Famous American Inventor
People go about their everyday lives without even giving a little bit of thought to their gadgets and
tools. It seems as if everyone in well–developed countries takes the small things for granted. Things
like new cars, smart devices, and advanced technology are much more significant things that helped
modernize the world. But what about the more ordinary things in a common household, like a water
boiler or a microwave? Take an oven, for example. People all over the country use ovens to cook at
home on a pretty regular basis, and restaurants use huge ovens all the time to keep up with their
customers' orders. Imagine how the world would be without something as simple as an oven.
Similarly, the calculator is one of the world's most subtly powerful ... Show more content on

The very first known "calculator" was the abacus, which was first developed in China. Many years
later in 1642, a French mathematician named Blaise Pascal invented the world's first adding
machine, which was driven by gears that were capable of doing basic addition and subtraction.
Pascal was the first true "inventor" of the calculator, but the patent on the calculator was granted to
Burroughs. In 1886, Burroughs invented his first commercial adding machine called the P100
Burroughs Adding Machine that almost resembled a typewriter. His invention was used as
inspiration for Otto Steiger, who invented the "Millionaire", which was essentially just Burroughs'
adding machine but capable of doing multiplication. However, the reason why Burroughs received
the patent was because he developed an oil–filled dashpot, which was hydraulic, for the calculator.
This dashpot ensured that the machine worked properly no matter what and that he could still get the
right answer, no matter the order the numbers were entered in. Unlike this newer and more
developed machine, Burroughs older adding machine was unreliable because depending on which
way you pulled its lever, you could get varying answers. In fact, his very first adding machine
weighed about 63 pounds! As time progressed, several inventors took Burroughs' model and made it
more and more portable. Now, the modern day calculators run on battery and electricity, and some

The Invention Of Science And Mathematics
The world is currently filled with a vast array of different electronics, many of which are extremely
useful and positively benefit society. None of these objects would be possible without the invention
of electricity, which some consider to be the most influential invention in modern history. However,
there is one particular electrical object which I believe has not only been useful to society, but has
also been extremely useful in my personal life. The calculator has had a tremendous impact on
science and mathematics, and there are many things today that have been made possible or easier
through its invention. Complex calculations are made easier and quicker, and newer calculators even
have the capability of performing higher level ... Show more content on Helpwriting.net ...
Although it was not capable of completing mathematical arithmetic, the first electronic computer
was created. This idea then fed into the creation of ENIAC in 1946, a computer capable of
completing the four basic mathematical functions. A few years later in 1961, ANITA was released.
ANITA is often considered to be the first desktop electronic calculator. As with many product life
cycles, calculators progressively got smaller with the creation of the first pocket calculator in 1967,
the Texas Instruments Cal–Tech. However, this calculator printed calculation results on a spool of
tape. It was not until the invention of the Sharp QT–8D in 1969 that the world was introduced to
what we now call the pocket calculator.
As the designs got smaller, the size of the electronic components had to as well. Early calculating
machines were purely mechanical, and the early electronic calculators relied on vacuum tubes,
which was not the quickest or most reliable way of getting the job done. In 1958 however, things
would begin to become smaller with the invention of the integrated circuit. "The integrated circuit is
nothing more than a very advanced electric circuit. An electric circuit is made from different
electrical components such as transistors, resistors, capacitors, and diodes that are connected to each
other in different ways. These components have different behaviors."

Logarithms During The Scientific Revolution Of The 17th...
Though the Scientific Revolution of the 17th century produced many inspiring inventions and
discoveries, one of the greatest contributions of the period, at least in the field of mathematics, was
the introduction of logarithms. Mathematically, a logarithm is denoted as follows logb(x)=y, where y
is the power to which b must be raised in order to produce the answer x. However, simply explained,
a logarithm is a quantity representing the power to which a fixed number, the base, must be raised to
produce a specific number. Therefore, to give just one computational example, log2(32) = 5 because
25 =32.
The term logarithm was derived from the Greek words for ratio and number. Conceptually speaking,
logarithms are the inverse operation of exponents. ... Show more content on Helpwriting.net ...
The combined efforts of Napier, Burgi, and Briggs contributed to the invention of a mathematical
calculation that is used daily in our modern life. By referring back to the logarithm tables, large and
tedious calculations can be avoided and simplified by simply performing two steps by using the
logarithm laws. This discovery arose in the time period when there were several mathematical and
scientific discoveries being made, and resulted in a highly convenient and faster method for
completing complex

Why Is Calculator Is Not Appropriate In The Classroom
Math Research Paper
Since the 1980's calculator use in the classroom has been a huge controversy between educators
(Golden, 2000). It is becoming increasingly common to use calculators in the classroom on a regular
basis. Some states allow students to use calculators on standardized tests and as part of the regular
curriculum (Dion, 2001). Because we live in such a technologically changing world, hand held
calculators have been far surpassed and can be purchased for as low as $4.00 each. This low price
however, has not swayed the many people that believe calculators are not appropriate in the
classroom.
These critics argue that calculators take away student's basic knowledge of mathematics, prevent
children from truly ... Show more content on Helpwriting.net ...
This evidence alone is enough proof, for some, that calculator use takes away basic skills and when
given a test where these skills come into play, children do not perform well. It is believed that the
difference in calculator use based on race and wealth may reinforce inequality in scholastic
achievement, rather than narrow them (Golden, 2000). Because calculators are so cheap, in
comparison with computers, most schools can afford to provide them for each student, therefore,
this is the only technology readily available to low–income schools and calculators are often
overused (Golden, 2000). In addition, another concern with calculators is that many children feel
they are cheating, taking the easy way out, or taking and illegal shortcut by using a calculator. They
think they are skipping out on the work and by doing so are being immoral (Dresdeck, 1999).
On the contrary, advocates of calculator use in the classroom claim that calculators allow students to
spend less time on tedious calculations and more time on understanding and solving problems, help
students develop better number sense, allow students to study math concepts that they could
otherwise not have time to perform without calculators, allow students who are normally turned off
to math increase

Ada Lovelace Research Paper
When we observe math classes today there is often a identifiable staple, heads bowed as they plug
numbers into a calculator and waiting less than a millisecond to get their answers and sometimes on
their phones waiting for the next picture to load. However, many of those who do use modern
technology, in classes or out, never truly know the story surrounding the creation of it and the
people who contributed to it. Ada Lovelace is often dubbed the very first computer program for her
contribution in creating the very first algorithm for the first computer and without her innovative
thoughts and ideas we may not have had much of the technology that necessitates our everyday
needs. Ada Byron was born in London on December 10th 1815, bother her

Should We Use The Calculator Usage? The United States...
With the United States falling behind in mathematics, they need to take a stand against the issue –
calculators. The United States is ranked thirty–fifth internationally (Desilver). Considering America
is supposed to be one of the superpowers of the world, they should be ranked much higher. To climb
in the ranks, the United States should stop allowing students to use their calculator as a crutch;
calculator usage should be monitored and restricted in the classroom. In elementary school, there
should be no calculator usage allowed. As they get older, the restrictions on calculators should
loosen. Middle school students should be allowed to learn different functions on the calculator, but
still learn the concept traditionally. Then, in high school, calculator usage is fairly accepted for
several math classes require the calculator to be able to solve the problems. To alter calculator
usage, the United States school system may need to redo math curriculum. They should alter their
lessons to focus on the student's mental math ability instead of if they can type into a calculator
correctly. To enforce restricted calculator usage, there are various boundaries each type of school
can set. In elementary school, they should not allow students to bring calculators to school; without
a calculator constantly at their fingertips, there is no temptation to use it for simple math. This
permits students to learn the concepts thoroughly before using a calculator as a crutch.

on me. First it taught me about the complexity of elementary mathematics and not to underestimate
it. Secondly, it taught me about the consequences becoming overly dependent on mathematical aids
(leading to doing and not understanding). Thirdly, it taught me the reasons behind why we do certain
mathematical procedures. Lastly it gave me tips for future teaching and parenting.
One of the main themes in this book is challenging the notion of how simple it is to teach
elementary kids. In fact it is profound. Often times, professional mathematicians are so enveloped in

This reminds us not to underestimate and overlook elementary mathematics that appears basic.
Mathematical diversions, therefore, cannot be taught without the students' understanding of the
basic mathematical foundations. It is like learning to play an instrument; one must know the basics
before being able to play a piece.
Learning about the long and tiresome process of transforming ordinary fractions into decimal
fractions has made me realize how much I had taken for granted using calculator for the past decade.
There are downsides to relying more on the calculator than relying on "old–fashioned" mind.
"Patterns as Aids" becomes a problem when a student follows rules without understanding and
calculates large numbers mentally using tricks but fails to understand the purpose of the processes or
steps. Therefore it is better to understand less but thoroughly, than to be an expert in memorizing
tricks and rules without any understanding. Principles must be taken apart, and each ingredient
learned and taught individually. When something sounds hard or difficult, it usually means we did
not break the problem into portions. Often I take for granted and overlooked simple aspects of math
that I automatically perform. This book also mentions the importance of using word

As everyone grows up, everyone has to take a Math class from Kindergarten to twelfth grade. At the
early stage of math classes, most of the problems were solved by using pencil and paper. Eventually,
calculators took over the method of using pencil and paper. Calculators were first made in 1642 by a
French mathematician, Blaise Pascal. According to the article, "Who Made the First Calculator,"
calculators were created for the usage of helping a person add and subtract numbers without using
their hands ("Who made the first calculator"). However, they were not introduced into classrooms
due to the cost, size, and appearance of the calculator. Eventually they became sleeker and less
expensive. Ever since then students started to use them in ... Show more content on Helpwriting.net
...
It is also very important that students learn how to estimate an answer without relying on the
calculator. As stated in an article, "Using calculator in elementary math," it is very easy to make
mistakes on the calculator (Using Calculators). Students must learn how to solve a problem before
using the calculator although a calculator does make the process go by faster. Although calculators
make the process of solving a math problem faster, it makes a person depend more on the calculator.
According to Doctor Ian there will be times when there is not a calculator around to use and if there
is one, the battery might be dead (Ian, Doctor). For example, on the EOGs and SATs, there may be
sections on the test that calculators are not permitted. For kids who depend on the calculator, it may
be harder for them to do math in their head. The calculator prevents students from doing critical
thinking. Students, who usually depend on the calculator, tend to be weak at analyzing their answers
to make sure that it is right (Calculators: Good or Bad). This may explain the student's poor score on
their EOGs and SATs. Calculators is a problem to young kids these days. It makes them depend
more on the calculator then trying to actually work it out in their mind. However there is a solution.
With the ever growing world of technology, students should be allowed to use calculators in the
classroom, but only when it is necessary. Basic math skills, such as addition, subtraction,

Computers And The Classroom : A Help Or A Crush
Calculators in the Classroom: A Help or a Crush This research topic will discuss whether students
use or abuse calculators in the classroom. There are a number of reasons for discussing this topic.
Mainly, the concern over students using calculators has proven to be an extremely split and
controversial subject for professional educators, parents and other such special interests groups for
several years. Since the first hand–held electronic calculators appeared on the market nearly 30
years ago, many people have voiced strong opinions on both sides of the issue in regards to the use
of calculators in the classroom. It is this writer's hypothesis that students should not be allowed to
use calculators to perform basic mathematical computations if they have not mastered the basic
concepts of subtraction, addition, multiplication, and division. Based upon classroom observations
of students in various classed, serious issues have arisen because of students who have no desire to
learn that 2*3=6 because they know that they have the choice to use the calculator instead. This
research will attempt to address both sides of this issue and seek to create some solutions and / or
recommendations to satisfy the educational requirements for the advancements of technology within
the classroom, without sacrificing basic learning principles. This research will contain information
gathered from professional educators, students, and parents to support the various opinions and
theories

Understanding The Concept Of Division
The purpose of this lesson is to introduce the students to the concept of division. This will be
somewhat of a review for the students who have had practice with division in past grade levels. It
has been a long time since the students have had any practice with division, so this lesson will serve
an introduction to the meaning of division, division vocabulary, as well as its relationship to
multiplication. Students will be introduced to fact families as a way to show the connection between
multiplication and division. The students will be able to see the relationship between a concept they
have had a lot of practice with (multiplication), to a concept that might be new to them (division).

Teens, or girls in general read this magazine, and by placing an ad such as this in the magazine
would generally boost sales. Another aspect of this ad that would commonly appeal to the teen age
group would have been the choice of colors, and the background of the advertisement.
As far as background goes, historical background is also relatively important in the relevance of the
TI–83+ silver edition graphing calculator advertisement. Teens have many choices when it comes to
graphing calculators, so that is probably why the author chose to include a feature that not all
calculators have. The phonebook feature would appeal greatly to the viewer, hence its purpose. This
particular feature, the phonebook, would be of importance because in the past no calculator
including all other Texas Instruments calculators has offered such a feature.
The Texas Instruments advertisement also allows the viewer to make assumptions in relation to the
pictures and text displayed on the page. These assumptions could be anything from the approximate
cost of the tool, to the pondering of the ray of colors used in the composition of the calculator itself.
These different conjectures are made due to the actual composition of the advertisement itself.
Then comes the purpose of the advertisement. The advertisement is presented to show the viewer
what a unique tool the TI–83+ silver edition is, and what new features are included in the calculator.

Solar powered calculators first came out in 1976–77. They became common in the mid–1980s and
now have become the most common. Calculators today have the time–alarm feature, computations
in multiple languages, solar power, the buttons are multitasked, and overall have more functions. A
cheap calculator today is only $2 or $3 and a more functional calculator could be $90.
Computers over the past decades have gone through tremendous changes. In 1960 the first
commercial computer was introduced as the first minicomputer that only consisted of a keyboard
and monitor (Polsson, 2003). It was not until 1963 that Douglas Engelbart, of the Stanford Research
Institute, invented the mouse. Five years later he demonstrated the keyboard, keypad, mouse, and
windows together at the Fall Joint Computer Conference. Also at this conference he demonstrated
word processor, a hypertext system, and a dynamic file linking (Polsson, 2003). Honeywell in 1969
released the "Kitchen Computer," the first home computer, at the price of $10,600. IBM, also in that
year, built SCAMP, one of the world's first personal computers, now more commonly called PCs
(Polsson, 2003). The first floppy disk which was an eight inch plastic disk called a "memory disk"
was introduced by IBM in 1967 (Brown, 2003). In 1976 the 5.25 inch floppy disk was produced;
another floppy disk, the 3.5 inch, was created in the 1980s (Brown, 2003).

The reason why it has this growth for best, average, and worst cases however is because of the way
the sort itself works. It compares the "smallest" (first index at first iteration) value it has to every
single other element in the array. Every time it finds a smaller, it redefines it as smallest, then once it

Interview With A Calculator
INTRODUCTION The purpose of this interview is to distinguish the learning between a high school
student of today's date with a student back in 80's. The methods we use today for our math solving
problem is very different as we rely more on calculators. Does it really going to help us remember it
after almost 15 years from today? Will we be able to solve a math problem without a calculator use?
I also wanted to analyze the misconception that both groups had regarding decimal division and
multiplication. London, Brightlemon and Tribal stated on their website of Count On some common
misconceptions about multiplying decimal numbers, one of them was about most people ignoring
the fact that 0.1 * 0.1 is the same as 1/10 * 1/10 which becomes 1/100 ... Show more content on

And mostly young people like the high school pupil often have the misconception that 6 divided by
15 is the same as 15 divided by 6. My cousin had the misconception exactly like Benny that
Erlwanger mentioned in his writing (https://drive.google.com/file/d/0B–
zCt1YBD2VJNFpDOFhyaEsyOG8/view?usp=sha). They often ignore which number is divided by
what. Calculators are also making younger generations mentally handicapped which doesn't allow
them to do a simple calculation without it, they rely more on it rather than trying to solve it
themselves. Consequently, more use of calculators at each and every class is increasing the
misconception of a small number divided by a larger number compared to the other facts I was
considering. Back in the old days, they were not allowed to use calculators at for every calculation
which made them faster at doing it themselves. My cousin took double the time compared to my
father as he was stuck in the division. Although he had done high school math after decades, he still
finished it faster than my cousin as he remembered the steps he had done in school. My cousin had
the misconception that if the denominator is greater than the numerator, it works the same way as it
would work for a smaller denominator. Benny from one of our readings also had the same problem
as my cousin. When he was asked to solve 4/11 and then 11/4. He answered that both would end up
having the same result, ignoring which is bigger: denominator or numerator. Considering the way
my cousin applied his methods for solving the problem of the division, it shows that he lacks the
"cognitive structure" and its "coordination" just like Benny. We have discussed in the class that
misconceptions are resistant to change and after the interviews I have realized that it is true. This is
because after the interview was done, my cousin still had the misconception that 15/6 gives

The Importance Of Computers And Technology
Computers and technology has evolved over the years and has come useful but there are many
reason that contract the good. Due to all this technology changed over the time, you can see that
human interaction has stopped and it has failed to fill our needs of education. What I mean by this is
that we are really not being educated but take what others put online and automatically believe it is
right. Instead of researching and making your own conclusion. Another reason to why computers
and technology is not good for society is because it has become very dangerous and harmful in
many ways.
Due to the growth and expansion of technology, on a daily basis now you can see less human
interaction compared to when we barely had any type of technology. A great example of this we you
go out to eat now, you usually see families and couples that are the tables on their phones. When
they can be talking communicating with each other and some even just text each other being at the
same table even though can say whatever they have to say right there. There was a study done "in
2012, in fact, scientists at the Chinese Academy of Sciences found that the brain chemicals of people
who habitually used the Internet (and were perhaps addicted to it) had abnormal connections
between the nerve fibers in their brain" (CNBC News). We are becoming very addicted to
technology because now we can not live without them. It has caused us, not to use our brain to think
but allowing someone or a device to do

absurd. The same idea applies to technology in the classroom. Calculators, in particular, are
becoming more readily available in the classroom, but technology should not stop there. Many

The myths include:
1. "Calculators are a crutch: They are used because students are too lazy to compute the answers on
their own; they do the work for the student."
2. "Because calculators do all of the work for the student, he/she will not be stimulated or
challenged enough." 3
3. "If I didn't need to use technology to learn math, then neither does my child. After all, I turned out
just fine."
4. "The use of calculators prevents students from effectively learning the basic mathematics they
will need when they enter the workforce."
5. "People will become so dependent on calculators that they will be rendered helpless without one.
(e.g.:
What if the battery dies or the student has to perform a computation when no calculator is
available?)" (Waits pg. 6–8)
Waits gives reasons why these myths are in fact false and why it is important for the myths to be
overcome by the public in his essay. In conjunction with the importance of parents and teachers
fostering technology is the importance for students to foster technology in the classroom.
Students should be taught to use technology as a tool for learning and not a "crutch." As noted in the

sites. She's always teaching me about computers and what their functions are, so I can know what to
do when my computer breaks down so that I can figure out what the situation is and how I'm
supposed to handle it all on my own.
I am a very antisocial person, so I rather use the internet to socialize instead of talking to people in

looking for good deals on items that I want. When I was in high school, I would go on the computer
a lot to help with my homework more than I did in middle school, because I would get harder
homework which would require more information from the computer. I would go online to get
research for my biology reports or help for my math homework or even my English reports.

The Pros And Cons Of AI And AI
The phenomena of computers have most certainly become an indispensable part of everyday life and
have inevitably revolutionized the way in which we live. Although their presence is made visible in
the small everyday aspects of life, computers more often than not mark their presence in the fields of
mathematics and science, where numbers become the language in storing and working with vast
quantitative data and information. It can then be said that in crunching numbers and processing such
vast information, computers are able to exhibit forms of knowing and understanding. Does this
mean then, that due their ability to process such large amounts of data, computers are able to attain a
degree of knowledge and understanding which far surpasses the human mind? While there may be

It is true that some Al programs are more flexible, with recent innovations regarding abilities of
knowing, reasoning and natural language processing and that of ASIMO, wherein an AI is able to
formulate a method as to how it would walk up a ramp. However, this may not exactly mean a
higher form of intelligence than that of a human's, as even if the AI is able to further evolve, it might
not necessarily mean that it would be able to gain the intelligence of an adult human. Human
intelligence, after all, cannot be defined by mere programming and algorithm. Thus, it could perhaps
be said that the AI lacks the ability to fully rationalize and reflect on its decisions. Therefore, as
computers, and ultimately AI are designed and programmed in a systematic way, they are in a sense

was invented by Presper Eckert, John W. Maulchy, and their associates. ENIAC was created during
World War II, it was used to calculate movement and strategies for the military during the war. It
was very helpful for America during World War II. John Vincent Atanasoff was born on October 4th,
1903. Atanasoff was a professor of mathematics and physics, that had always been interested in
finding new ways to perform mathematical calculations at a faster rate. He was the inventor of the
electric digital computer. Clifford Berry, a graduate student, and also a gifted engineer helped in
assisting Atanasoff in building that world 's first electronic computer. ""In December 1939, the first
prototype of the Atanasoff Berry Computer (ABC) was ready"" (Do 2). ""John Vincent Ananasoff
gave birth to the field of electronic computing, in doing so, he also gave birth to a new era, an era of

Technology And Its Impact On Our Lives
Computers and technology at large have changed the lives of many people in the world both
positively and negatively. Computers have unveiled many things which have greatly influenced our
lives. This has made many teachers and students to adopt their use in classrooms. However, the use
of computers in our classrooms has been characterized by over reliance on them. Cyber space has
also played key roles in our lives. For instance, there is an increase in the number of research papers
done each day while, on the other hand, movies watched by students has increased. These can be
controlled through regulations and legislation from the governing bodies. However, the author says
that 'Cyberspace is a voluntary destination' and "Regardless of how many laws or lawsuit are
launched, regulation won't work". However, many people have used virtual books for their own
benefit helping them write good research papers. We will critically analyze the literature behind the
use of technology, mainly computers, to see how they have influenced our lives both positively and
negatively. We will also look at the effectiveness of computer usage in our classrooms today.
Computers are an advantage for learners in both scientific and technological education as compared
to books. Approximately 2 billion dollars have been used to purchases of more than 2 million
computers in America (Gelemter, 1994). However, computers are awaited in a religious fear in both

The tool was also a weakness, because the students had seen it once before by taking the pre–
assessment. The pre– and post–assessment could have been better if the researcher had either mixed
up the order of the problems or made a completely different assessment with the same type of
problems. Problems Encountered Problems encountered during the execution of the project were
excessive student absences, lack of consent, and school assemblies. One of the target students in the
study had excessive absences due to behavior. The student got in some trouble that required that
they spend time in In–school suspension as well as Out–school suspension. This problem made it
impossible for the students data to be included in the study. A couple of students did not return the
consent form. One student in particular needed multiple copies while the other student just never
gave the consent to their parents. Unscheduled school assemblies served as a problem as well. Since
they were unschedule, they were not taken into consideration when planning the study. The
assemblies were also mandatory, so there was no way to get around not attending. Influential
Factors Factors that may have skewed the findings were wording of a interview questions and grade
level mathematics class. Students needed for the researcher to explain exactly what was meant on

calculator should be used, we will decide at what points should they be used. In order to do that we
will discuss the pros and cons of calculators in beginning algebra.
What are the pros of using a calculator in this course? There are three main pros of using a
calculator in beginning algebra. The three main points I am going to hit are technology knowledge,
enjoyment and accuracy. Technology is a huge part in today's learning experience, so I think its a
good idea for the students to learn how to use a calculator. Math is horrible anyways so having a
calculator will help make math more enjoyable. If your teacher hates the idea of using a calculator
then maybe you should bring up a calculator day. The final pro of using a calculator in math is
Accuracy. Accuracy is very important in math. That is why I personally think we need to use
calculator in math to check our work and if we answered the problem wrong then we will need to go
back and re work it out so we can get it right. Calculator are immensely valuate for validating work.
Students should learn calculators are helpful tools and a tool that should not be taken advantage of.

Teaching The Flexible Learning Program
Literature Review(10) One of the areas that students find most challenging is math. For the past
three years I have been teaching The Flexible Learning program, which covers 6th, 7th and 8th
grade Mathematics. The curriculum is was created by both the district curriculum staff as well as the
federal programs department of the school system. The Flexible Learning Program (FLP) focuses on
mathematics for grades 6–8 for students who are at the highest risk academically. The program is
supplemental to the student's CCGPS classroom, remedial class and Title I support. The curriculum
in the classroom is aligned to the Common Core Georgia Performance Standards adopted by the
state.
Each student is given an individual student plan that is used to help them reach their own learning
goals. The students in my class are usually labeled as special education kids. More than half of the
students that are enrolled in my class have IEP with some type of accommodation. My school
district prides itself on being one of the leading districts in technology. Each school has been
eqipped I–pad carts, Cromebooks, projectors, clickers and other instructional technology.
Since it is in the schools, it has been stressed to use them in our lessons. I personally do not have a
problem using technology to a point. In math class you expect students to be able to use calculators,
but how much is too much? Students are relying heavily on the use of calculators to answer basic

I have always been a firm believer in the utilization of technology on regular occasions, in my

Smart Boards, Airliner Wireless Slates, Classroom Performance Systems, Document Cameras, and
of course computers. I believe that in order for our students to be successful in today's workplace,
computer literacy is a necessity. My philosophy on technology is this, in order for us and our
students to be competitive in today's workforce, we must be sure to educate our students on how to
properly use it. The most commonly used form of technology, in our classrooms, is the computer. In
order for the computers to be used correctly, and computer time to be used effectively students must
adhere to the guidelines set in place. The following guidelines, from Betty Kistler would be great to
post in at the computer stations in the classroom;
(1) Keep your hands off the keyboard and mouse until you know what we're doing.
(2) Work quietly and stay on task. Make every effort to do your best.

printing)
(4) Get permission if you want to use the internet for anything other than the day's assignment. (give
students with permission a brightly colored card)
(5) Leave your workspace the way you'd like

This method involves drawing a second line adjacent to the original 4cm line and drawing the 8mm
scale onto this line. Then dividing both these lines into four parts to reveal that 1cm represents 2mm.
When I came across this question I felt confident in my ability to answer it. Throughout high school
I was exposed to many similar questions; because algebra was heavily focused on in my
mathematics classes. To answer the question I converted the written instructions into an algebraic
statement. So, each sentence was represented by a series of letters and numbers instead of the
original words. The algebraic expression that I formed matched one of the possible answers; thus, I
felt confident with my final answer. This question is linked to the Australian Curriculum's 'Patterns
and Algebra' content descriptor (ACMNA176) which requires children to "create algebraic
expressions and evaluate them by substituting a given value for each variable" (ACARA, n.d.).
Algebra is essentially the study of mathematical symbols and the rules for manipulating these
symbols. Thus, by converting written sentences in symbolic numerical expressions, algebra has been
utilised. More specifically, an algorithm has been followed. Algorithms are step by step guides on
how to do something. Thus, the series of clear steps listed in this question creates an

HP-48SX Scientific Expandable Calculator Essay
HP–48SX Scientific Expandable Calculator
History
The HP–48SX Scientific Expandable calculator was manufactured by Hewlett Packard and the
copyright is dated 1989. At the time of release, the HP–48 series was the most advanced line of
scientific calculators available to those in the technical fields. I purchased the calculator in 1991
through a high school mathematics program. It has been used extensively since then for virtually
every class I have taken. So far, the calculator has never malfunctioned.
Material
The main material of the HP–48SX is plastic. The case is hard brown plastic. The front panel is a
thin metal sheet with soft plastic buttons. The screen is a large liquid crystal display.
For a much more detailed ... Show more content on Helpwriting.net ...
The HP–48SX has little other ornaments besides the screen and keypad interface. These few
ornaments are comprised of the Hewlett Packard logo, the 48SX model number, and the serial
number on the back. Soon after purchasing the calculator, I carved my first name, last name, and
high school nickname into the plastic back cover in order to identify the calculator as mine.
Function
The intended functions of the HP–48SX are the standard functions of a scientific calculator, plus
several unique to the HP. This calculator can graph all functions, perform all mathematic operations,
convert units for most properties, and solve equations. It also can store data in a database and
perform statistical operations on this data. This last ability reveals one of the calculator's intended
functions of laboratory assistant.
There are many unintended functions for the HP. The main one is a source of entertainment. Games
such as Pac–man, Joust, Tron, and Tetris can all be easily obtained and installed on the calculator.
The wide selection of games can provide hours of amusement.
The data storage capability gives the HP–48SX many more unintended functions. It can hold phone
numbers, grades, banking information, formulas, and almost any other data imaginable. The HP can
be used as a personal organizer for virtually all aspects of life.

Evaluation
The HP–48SX calculator performs its functions more than adequately.

It has its advantages and also disadvantages which are sometimes alarming and one of these
disadvantages are that when students do not know the basics and they are already using the

foundation of knowledge in mathematics if they will not know mental calculation and solving
problems by just thinking and not using any of the modern devices nowadays. This problem had
been studied for years because researchers are curious if a calculator can really affect one's way of
dealing with numbers mentally. Mathematics has different fields and all includes basic calculations
and one must first know how to analyze the things needed in a problem. A problem may need some
manipulations first before performing calculations and a student very dependent to calculators might
have a problem answering it. Calculators are just instruments which can help us improve our skills

We Need Up Our Carbon And Water Footprint
Sometimes we, as humans, don't realize how much we use our resources. This project opened my
eyes to how much we waste every day. The resources and how we use them on a day–to–day basis
make up our carbon and water footprint. I used the two websites
http://coolclimate.berkeley.edu/calculator and http://waterfootprint.org/en/resources to calculate my
impact on the world. The results definitely made me think about how I use my resources. For the
two online calculators, I put in information such as how much I travel, how many loads of laundry I
do, how much meat I eat, and even how often I wash my hands. The websites then took all of my
information and calculated it to give me my specific carbon and water footprints. A carbon footprint
is the closest estimation we have to the total set of greenhouse emissions as set forth by one specific
person. The online calculator calculated my footprint to be 21.9 tons of CO2 per year. This means,
with the way I am currently living, I am either directly, or somewhere down the line, party to
emitting close to 22 tons of CO2 into our environment. The carbon footprint calculator not only told
me how much my total carbon footprint is, but also specifically where my carbon emissions came
from. Table 1.1 shows the majority of my results. The first question the calculator asked was how
much I use my car. I live only two hours away from school, hardly ever go home, and walk to my
