Study Notes

Integers

Defined as the set of all whole numbers, including negative whole numbers.
Represented by the symbol "Z."
Includes both negative and positive whole numbers along with zero: ( Z = {-3, -2, -1, 0, 1, 2, 3} ).
Examples include: -52, 0, -1, 16, 82.

Whole Numbers

Known as natural numbers including zero; they consist of all non-negative integers.
Represented by the letter "W."
The set of whole numbers is defined as: ( W = {0, 1, 2, 3, 4, 5,...} ).
Examples include: 67, 0, 49, 52.

Rational Numbers

Any number that can be expressed in the form ( p/q ) (where p and q are integers and q ≠ 0) is classified as a rational number.
Represented by the letter "Q."
Examples include:
- ( 7/1 )
- ( 10/2 )
- ( 1/1 )
- ( 0/1 )

Types of Numbers in Maths

Numbers are categorized based on properties and representation on the number line.
Each number classification has specific descriptions, properties, and examples for better understanding.

Natural Numbers

Also known as "counting numbers," consisting solely of positive integers.
Represented by the letter "N."
The set of natural numbers is defined as: ( N = {1, 2, 3, 4, 5,...} ).
Examples include: 35, 59, 110.
