It provides a unique representation of every number and represents the arithmetic and algebraic structure of the figures. It also allows us to operate arithmetic operations like addition, subtraction and division.
A number system is a way of representing and organizing numbers. There are several types of number systems, including:
1. Binary Number System: uses only two digits, 0 and 1, to represent numbers.
2. Decimal Number System: uses ten digits, 0 to 9, to represent numbers. It is the most commonly used number system in daily life.
3. Octal Number System: uses eight digits, 0 to 7, to represent numbers.
4. Hexadecimal Number System: uses sixteen digits, 0 to 9 and A to F, to represent numbers.
5. Scientific Notation: represents numbers in a compact form by expressing them as a product of a power of 10 and a number between 1 and 10.
Each number system has its own advantages and disadvantages, and they are used in different applications based on their suitability.
Here are some important things to know about number systems:
1. Number systems are used to represent and store numerical values in computers and other digital devices.
2. The choice of a number system depends on the requirement of a specific application, and each number system has its own advantages and disadvantages.
3. The decimal number system is widely used in daily life, but binary and hexadecimal number systems are more commonly used in computer programming and electronic devices.
4. Converting between different number systems requires an understanding of the place value system, which assigns different values to each digit based on its position in the number.
5. The binary number system is particularly important to understand in the context of computer science, as it is used to represent data in the form of bits, and all data processed by computers is ultimately represented as binary numbers.
6. The hexadecimal number system is commonly used in computer programming because it is more compact and easier to read than binary or decimal representations of large numbers.
7. The octal number system is used less frequently in modern computer systems, but it is still used in some specialized applications.
Number System is a method of representing Numbers on the Number Line with the help of a set of Symbols and rules. These symbols range from 0-9 and are termed as digits. Number System is used to perform mathematical computations ranging from great scientific calculations to calculations like counting the number of Toys for a Kid or Number chocolates remaining in the box. Number Systems comprise of multiple types based on the base value for its digits.
What is the Number Line?
A Number line is a representation of Numbers with a fixed interval in between on a straight line. A Number line contains all the types of numbers like natural numbers, rationals, Integers, etc. Numbers on the number line increase while moving Left to Right and decrease while moving from right to left. Ends of a number line are not defined i.e., numbers on a number line range from infinity on the left side of the zero to infinity on the right side of the zero.
Positive Numbers: Numbers that are represented on the right side of the zero are termed as Positive Numbers. The value of these numbers increases on moving towards the right. Positive numbers are used for Addition between numbers. Example: 1, 2, 3, 4, …
Negative Numbers: Numbers that are represented on the left side of the zero are termed as Negative Numbers. The value of these numbers decreases on moving towards the left. Negative numbers are used for Subtraction between numbers. Example: -1, -2, -3, -4, …
Number and Its Types
A number is a value created by the combination of digits with the help of certain rules. These numbers are used to represent arithmetical quantities. A digit is a symbol from a set 10 symbols ranging from 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Any combination of digits represents a Number. The size of a Number depends on the count of digits that are used for its creation.
For Example: 123, 124, 0.345, -16, 73, 9, etc.
Types of Numbers
Numbers are of various types depending upon the patterns of digits that are used for their creation. Various symbols and rules are also applied on Numbers which classifies them into a variety of different types:
Number and Its Types
1. Natural Numbers: Natural Numbers are the most basic type of Numbers that range from 1 to infinity. These numbers are also called Positive Numbers or Counting Numbers. Natural Numbers are represented by the symbol N.
Example: 1, 2, 3, 4, 5, 6, 7, and so on.
2. Whole Numbers: Whole Numbers are basically the Natural Numbers, but they also include ‘zero’. Whole numbers are represented by the symbol W.
Example: 0, 1, 2, 3, 4, and so on.
3. Integers: Integers are the collection of Whole Numbers plus the negative values of the Natural Numbers. Integers do not include fraction numbers i.e. they can’t be written in a/b form. The range of Integers is from the Infinity at the Negative end and Infinity at the Positive end, including zero. Integers are represented by the symbol Z.
Example: ...,-4, -3, -2, -1, 0, 1, 2, 3, 4,...

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This presentation provides an introduction to quantitative trait loci (QTL) analysis and marker-assisted selection (MAS) in plant breeding. The presentation begins by explaining the type of quantitative traits. The process of QTL analysis, including the use of molecular genetic markers and statistical methods, is discussed. Practical examples demonstrating the power of MAS are provided, such as its use in improving crop traits in plant breeding programs. Overall, this presentation offers a comprehensive overview of these important genomics-based approaches that are transforming modern agriculture.
3. Introduction
Number systems are systems in mathematics that are used
to express numbers in various forms and are understood
by computers. A number is a mathematical value used for
counting and measuring objects, and for performing
arithmetic calculations. Numbers have various categories
like natural numbers, whole numbers, rational and
irrational numbers, and so on. Similarly, there are various
types of number systems that have different properties,
like the binary number system, the octal number system,
the decimal number system, and the hexadecimal number
system.

[1]
5. 1. Decimal
The decimal number system or the base 10 number system uses 10 digits ranging from
0 to 9 to represent any number. The first position from the rightmost part of a decimal
number is known as one's place or unit's place, then the second position is known as
ten's place, and so on. Every decimal number is represented by the power of base 10.
For example, the number 1457 is represented as:
03
6. 2. Binary
The binary number system or the base 2 number system uses only two digits i.e. 0 and 1
to represent any number. For example, the decimal number 14 is represented as 1110 in
the binary number system. We need to keep dividing the decimal number by 2 until the
quotient becomes 0 and along with that, we need to remember the remainder. When
the remainders obtained in the division are represented in reverse order, a binary
number is generated.
04
7. 3. Octal
The octal number system or the base 8 number system uses 8 digits ranging from 0 to 7
to represent any number. The octal number is very commonly used the computer
systems.
Every octal number is represented by the power of base 8.
For example, the number 215 is represented as:
05
8. 4. Hexadecimal
The hexadecimal number system or the base 16 number system uses 16 digits ranging
from 0 to 9 (i.e. 10 digits) and A to F (i.e. 6 digits) to represent any number. Refer to the
chart shown below to know the representation of hexadecimal numbers.
Hexadecimal 0 1 2 3 4 5 6 7 8 9 A B C D E F
Decimal 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
06
9. We can convert a decimal number into a hexadecimal number. We need to keep
dividing the decimal number by 16 until the remainder becomes 0 and along with that,
we need to remember the remainder. When the remainders obtained in the division are
represented in reverse order, the hexadecimal number is generated.
