About Calculator Apps project
This is a customized snack course for teachers and students of elementary and secondary schools
worldwide, as part of the sustainable development project for quality education via global goals; for
those who are new to computer programming and would love to have a starter pack to inspire them.
Also, teachers who find it difficult to introduce computer programming in their classrooms, especially
to ages 8 and 15 students will find it helpful to use, as a Kickstarter into explaining the rudiments of
coding to these categories of young children.
Small Basic is the sample programming language throughout this course due to it’s simplicity.
It would be very difficult to introduce majority of young students into computer programming no
matter how easy it is, without first creating a background check on Algorithms and how our day to
day living depends on them.
At interval you will meet my sidekick on Small Basic, his name is Wazobi, a stick figure that will take
you through the course via animated videos.

Overview/Purpose: To enable learners understand Algorithms and how we create them on daily basis.

Algorithm
Humans work with algorithms everyday unconsciously. This is how we live and this is also how
things get done from your to-do list to your shopping lists.
The algorithm of an average student’s life is as simple as:
This can be expanded into details by breaking down each step further into mini algorithms like a
table of contents.
An Algorithm is simply a list of processes to complete a specific task or event.
Algorithms help us understand how to write codes for the computer.
Step 1: Home
Step 2: School
Step 3: Home
Step 1: Home
Step 1.1 Brush(Teeth)
Step 1.2 Bath
Step 2: School
Step 3: Home

Logical Algorithms
We have several logical or conditional ways of creating algorithms by using IF, GOTO and ENDIF
and ELSIF commands. These are also Small Basic commands.
Lets change your normal student routine, to a situation that happens
when you fall sick on a school day.
You find that our normal TASKS will change when there is a new EVENT.
Step 1: Home
Step 2: IF sick
Step 3: GOTO hospital
Step 4: ELSEIF treated
Step 5: GOTO School
Step 6: ENDIF Home
Step 1: Home
Step 2: School
Step 3: Home

Algorithm example 1
An Algorithm is like a cookbook you can not eat the menu on paper after
shopping for items. The foodstuffs has to cooked according to the process in the
menu.
If your tummy was a computer, it wouldn’t know how to digest raw foods; the
cookbook is the algorithm, the chef is the programmer, while cooking the
foodstuffs is the programming language.
When you eat raw food you can become sick or get nauseated, because your
tummy might be rejecting the raw form of the food.
A computer programming language will reject an algorithm, if it doesn’t
understand the form the algorithm was typed.

Algorithm example 2
You understand only English Language and you are given an essay to read in Chinese;
you will need to ask someone that understands Chinese and English languages to
translate it for you.
The person who translates would write an short note (algorithm) on the meaning of
each Chinese word or sentences in English, before typing as the essay for you.
Humans can only teach computers in special languages called programming languages
or codes. Algorithms helps us understand how computers work and they are the best
way to explain our commands to computers.
Algorithms are written step-by-step and computer programming languages obey
commands (codes) one step at a time.

Algorithm and Math
The basic mathematical symbols/operators :
1. Addition (on keyboard “+”)
2. Subtraction (on keyboard “-”)
3. Division (on keyboard “/”
4. Multiplication (on keyboard “*”)
In computer programming, humans are the teachers, while computers are the learners.
Computers are blind, deaf, dumb, and they are still growing; your job as a programmer is to teach computers to see,
hear, talk and solve problems faster, so you have more time to play.
When writing an Algorithm for a computer code, you are going to use a mouse and keyboard, your algorithm will
have similarities with keys on the keyboard.
By teaching a computer to solve a problem, it will never forget it. This will give you time to focus on teaching the
computer more algorithms.

Algorithm and math exercises.
If you had a job that pays you $1000 monthly to add two numbers each minute everyday. Would it
not be smart to let your computer do the math?
This is a simple exercise in numeracy (2 + 3 = 5).
We can use images to represent the numbers
Now solve this: 1,000,000,000,000,000,000,000,000,000 + 2,000,000,000 = ?
Both exercises are still the addition of two numbers but the second exercise will take you more time
to figure out and pronounce. But it will take a computer the same time (less than 0.1 sec) to calculate
both math exercises with an algorithm that can be changed into a Small Basic code.

Algorithm and math exercises contd.
Algorithm solution: (2 + 3 = 5). The plus and equal (+, =) signs are the only stable (constants) items in the math
exercise, the rest are unstable “2,3,5” (variables/changing).
We need to create a formula to keep adding two numbers, and formulas are created using the ALPHABET, but NUMBERS
are used to test if the formulas can calculate.
With this algorithm we can use any computer programming language to write a code to add up two numbers, even if the
numbers are in trillions.
the formula now has to come before the answer, so we swop the Steps 3 to Step 4, to make the algorithm calculate
properly.
Step 1: The first number is 2, we can call it alphabet A
Step 2: The second number is 3, we can call it X
Step 3: The third number is the answer 5, we can call it Z
Step 4: The formula looks like this (A+X=Z)
Step 3: A+X = Z
Step 4: Z = 16
Step 1: First alphabet A = 11
Step 2: Second alphabet X = 5

Algorithm and math exercises contd.
By changing the mathematical sign we can write an algorithm to subtract or multiply or divide any
two numbers; which looks like this:
With just one algorithm we have four more algorithms that can be made into simple calculator
apps, using Small Basic programming language.
An algorithm also helps us control how an app should work. Robots, the internet, software, apps
all work with specific algorithms.
We will learn how to convert our algorithms into Small Basic codes for the computer to learn
how to make use of it.
Step 4: The formula looks like this (A+X=Z) or (A-X=Z) or (A/X=Z) or (A*X=Z)

Algorithm for shapes
The algorithm for finding the area of a square:
The algorithm for finding the Perimeter of a square:
Remember all sides of a
square are equal, so you
do not need to have
different length, width
or height.
For other shapes like
the rectangle we will
need to add more steps
to our algorithm to get
numbers for width or
base height.
Step 1: Length of one side is G
Step 2: Area = G*G
Step 1: Length of one side is K
Step 2: Perimeter = 4K

Congratulations
you completed your
lesson on Algorithms.

Soccer commands and
Small Basic Programming
Lets compare playing soccer (football) to Small Basic programming:
Soccer as a sport is made of some rules which makes us call it a game.
Other sports like hockey, basketball, polo, NFL all have their special rules that
makes playing their games special.
You can not apply soccer rules to hockey, neither can you apply basketball
rules to NFL.
Computer programming languages are software with special commands for
creating apps. They are like different sports with their special rules.
Small Basic has it’s own unique commands that helps you create apps.

SOCCER COMMANDS/RULES
One big soccer rule is kicking the ball; we can call it the KickBall command (STATEMENT,
VERB(action word), Rule), which is done with the LEGS only, we do not kick the ball with our
hands. It is wrong or an error to do that. We must KickBall to Pass, Dribble or take a Shot.
We can make up a Soccer Command Plan: Lets put these soccer commands into groups i.e
1. KickBall (STATEMENT group);
2. Pass, Dribble, Shot (PROPERTY group). Statement and property are separated by a DOT;
3. Actions you put inside the bracket (OPERATIONS group)
KickBall
KickBall.Pass (a team mate to read your action)
KickBall.Dribble (trick opponent with the ball)
KickBall.Shot (towards a distant position)
Automatic ball actions
includes (this will lead us to
conditional commands:
1. Ball Bounces.
2. Ball spinning on the
floor.
3. Ball going out of the
field.

Small Basic Calculator app
EDITOR and SOURCE CODE
All rules in soccer work only in the FIELD; similarly in Small Basic, we have an
EDITOR that allows us to type in all commands that Small Basic must obey, in order
to create our Calculator apps, we call these step-by-step commands SOURCE
CODES. The Small Basic EDITOR looks like the photo below:
F5 or RUN tells Small Basic to create an app from all
commands (SOURCE CODES) we typed in the Editor
LINES numbers gives us the number of code line typed, when
we press the F5 key or RUN button.
Source Code Editor for typing codes

1. TextWindow.WriteLine() - Moves & displays text on a new line in app screen.
2. TextWindow.Write() - Leaves & displays text on same line in app screen.
3. TextWindow.Read() - Allows letters to be typed in app screen.
4. TextWindow.ReadNumber() - Allows numbers to be typed in app screen.
5. Math.Power(number, powernumber) - i.e. 73 is Math.Power(7,3)
6. Math.Pi or Math.Cos() or Math.Tan() or Math.Sin() i.e. Math.Cos(30)
7. Math.SquareRoot() - To get the square root of a number.
8. GOTO, THEN - Command for branching one code to another.
9. IF, ELSEIF, ENDIF. - To create a branch of events when coding.
10. Inverted comma ‘ - Allows you comment on a line of code
11. Quote marks “” - Works with .Write() or .WriteLine to display text
in quote marks on app screen. ie.
12. Variables - Numbers or letters you create that are not in Small Basic;
commands i.e. total = sum1 + sum2
Summary of important Small Basic commands
for the Calculator Apps lesson

Small Basic Calculator app
(Statements, Properties, Operations)
Small Basic app screen command is TextWindow. Like the KickBall STATEMENT works with
other commands like (PASS, DRIBBLE or SHOT) separated by a DOT in our Soccer Command
Plan.
All calculators have a small screen that displays RESULTS. The TextWindow STATEMENT
command tells Small Basic to display a small black app screen after the next command, when
we press the F5 button on the keyboard or click RUN on the monitor.
The small black screen shows that our calculator apps can display any result we are going to
program on the SOURCE CODE editor.
Small black app screen
appears after pressing
F5/RUN button
Source Code

TextWindow Properties and Operations
Our entire lesson is focused on making Calculator apps,
using 5 Small Basic commands.
Small basic understands when you use the commands in
the combination given below:
i.e. TextWindow.Write (“Calculator Apps”)
Displays the comment in the quote on the small black app
screen after pressing F5/RUN.
Using WriteLine instead of Write put your cursor on the
next line in the small black app screen.
TextWindow.ReadNumber()
Displays a cursor for you to type in numbers only on the
small black app screen after pressing F5 Take note of the
DOT in-between the STATEMENT and PROPERTIES
TextWindow
Write

IntelliSense & Comments
1. IntelliSense in Small basic provides suggestions on commands you try using
on your EDITOR via a small box. It also provide you with the proper spelling and
usage of a command you are not too sure of.
2. Comments help you keep a note on each line of command you typed. As a
young computer programmer, it is easy to forget the use of a code your typed
on the Editor; a comment uses an “Inverted comma”, which tells Small Basic to
ignore any command after the inverted comma. i.e ‘this is to test comments.

Coding branches
Making a branch code is like turning your program into a cross road; or when
you try adding a menu options into your app.
You will notice such events on a phone call voice menu
i.e. For English press 1
For Spanish press 2
GOTO, THEN, IF, ELSEIF & ENDIF are branch commands in Small Basic.
IF English THEN
GOTO 1
ELSEIF Spanish THEN
GOTO 2
ELSEIF Yoruba THEN
GOTO 3
ELSEIF Hausa THEN
GOTO 4
ENDIF
Press 1 for English.
Press 2 for Hindi.
Press 3 for Yoruba.
Press 4 for Chinese.
1
2
3
4
For each branch you will
have to create other events
when coding. These events
represents each branch,
which are options your app
gives the user.

Debugging
Debugging your code is correcting errors
(bugs) you made in the source code editor
during typing or working with Small Basic
codes.
Making errors or mistakes in your source code
stops your code from becoming a app when
your press F5 or RUN button.
Small Basic EDITOR will show you the LINE
number(s) where error(s) where found, with
an error message on each line.
You can also debug a code by reading the
COMMENTS section to know what it was
meant to do; then you can rewrite the
algorithm.
The LINE number where
an error was found.
Error messages to read

Code debugging exercises 1
1. Type the codes and do not copy directly into your Small Basic source code editor.
2. Read the comments to find out what each line of code is meant to calculate.
3. Retype the correct commands, formulas or algorithm.
4. Use F5 or RUN button to test and see if the source can now create an app screen
TextWindow.Write("Type a number to know the 2nd power:") ‘displays text
square = TextWindow.ReadNumber() app ask for number
TextWindow.Write("The square of the number:") ‘displays text in quote
TextWindow.Writeline(Math.Power(square,2)) displays the the 2nd power
TextWindow.Write("Type a number to know the fourth power:") ‘displays text
fourthpower = TextWindow.ReadNumber() ‘to type a number
TextWindow.Write("The fourth power of the number:") ‘displays text in quote
TextWindow.Writeline(Math.Power(square,1)) ‘displays fourth power of number

Code debugging exercises 2
1. Type the codes and do not copy directly into your Small Basic source code editor.
2. Read the comments to find out what the code is meant to calculate.
3. Retype the correct commands, formulas or algorithm.
4. Use F5 or RUN button to test and see if the source can now create an app screen
TextWindow.WriteLine("A app to add two numbers") ‘to display text in quote
Write("Type the first number we call A:") ‘to display text in quote
firstnumber = TextWindow.ReadNumber() ‘app asks for number
TextWindow.Write("Type the second number we call X:") ‘to display text in quote
secondnumber = TextWindow.ReadNumber()
addingnumbers = firstnumber + secondnumber
TextWindow.Write("Addition of the two numbers:") ‘to display text in quote
TextWindow.Writeline(addingnumbers) ‘to display text in quote
TextWindow.WriteLine("A program to multiply two numbers") ‘to display text
firstnumber = TextWindow.ReadNumber() ‘to get 1st number
