2. DEFINITION OF NUMBER All counting digits are called numbers.
For example- 0,1,2,3...

3. NUMBER LINE - 4 - 3 - 2 - 1 1 2 3 4

4. TYPES OF NUMBER Naturals numbers Whole numbers Even numbers
Odd numbers
Prime numbers
Rational numbers
Irrational numbers

5. 1. Natural numbers
Those numbers which starts from one and ends to infinity.
For example- 1,2,3,4,..

6. 2.Whole numbers
Those numbers which starts from zero and ends to infinity.
For example- 0,1,2,3,..
All naturals numbers are also whole numbers but all whole numbers are not natural numbers. Because whole numbers contains 0 which is not natural number.

7. Even numbers
Those numbers which are divisible by 2, are called even numbers.
For example- 2,4,6,...

8. Odd numbers

For example- 1,3,5,..

9. Prime numbers
Those numbers which has only two factors, are called Prime numbers.
For example- 2,5 are prime number because these numbers have two factors. 5 2 2 1 5 1

10. Rational numbers
Those numbers which are in forms of p/q, are called rational numbers.(where q is not equals to 0)
For example- 3/4, 5/7 are rational number.

11. Irrational numbers
Those numbers which are in the form of square root, are called irrational number.
For example- 2

12. Importance of number system
Number system is very useful in our daily life.
All calculations are also based on number system.
For example , if we want to purchase anything then knowledge of number system is necessary.
