******* WHOLE NUMBERS******

WHOLE NUMBER

* The series of number starting from zero is called whole number.
eg: 0,900000,56789.

Natural no: * The series of number starting from 1 is called natural number.
eg:23,1,4,5,6

* Natural numbers and Whole numbers are divided into two groups
odd number and even number.

* Even number: The number which is the multiple of 2 is called even number
for eg:2,4,6,8,10,12.
*Odd number:The set of numbers other than even number is called odd number.
For eg:1,3,5,7,9,11.

* Natural numbers and Whole numbers are divided into further two groups
Composite numbers and Prime numbers.

* Prime numbers: The numbers which has only two factors(divisor) one and number itself.
for eg1,2,13,23,59 etc.
*Composite numbers: The numbers which has more than two factors(divisor) is called composite numbers.
For eg:16,3333,56,78,2290 etc
