**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.
