Properties of Whole Numbers

The properties of whole numbers are as follows:

• The number 0 is the first and the smallest whole numbers.

• All natural numbers along with zero are called whole numbers

• There is no last or greatest whole number.

• There is no largest whole number since they are infinite.

• There is infinitely many or uncountable number of whole numbers.

• All natural numbers are whole numbers.

• Each number is 1 more than its previous number. 

• All whole numbers are not natural numbers.

For example: 0 is a whole number but it is not a natural number.

• Whole numbers are denoted by 'W' normally.

Note:
The system has infinite numbers. 
Thus, W = {0, 1, 2, 3, 4, ……….}


Even Whole Numbers (E): 
A system of whole numbers, which are divisible by 2 or are multiples of 2, is called a set of even numbers. It is denoted by 'E'. 

Thus, E = {2, 4, 6, 8, 10, 12, .....} 
There are infinite even numbers. 


Odd Whole Numbers (O): 
A system of whole numbers, which are not divisible by 2 or are not multiples of 2, is called a set of odd numbers. It is denoted by 'O'.

Thus, O = {1, 3, 5, 7, 9, 11, .....} 
There are infinite odd numbers. 

Note:
0’ (Zero) is neither a negative number nor a positive number, it’s a natural number.
