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.
