About Whole Numbers

We use counting numbers in our daily lives, such as 1, 2, 3,…..and so on. Thus, Whole numbers are all of the basic counting numbers plus 0. Zero is the smallest whole number. In whole numbers, 0 has no predecessor or preceding number. There is no such thing as the ‘largest’ whole number.
Negative numbers, decimals, and fractions are not whole numbers.


Whole Number Symbol

The alphabet ‘W’ in capital letters is used to represent whole numbers.

W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,…}

Whole Numbers on Number Line

These numbers are easily visible on a number line because the number line, in general, represents integers from – to +, and whole numbers are positive integers, including 0. A number line shows that the integers on the right side of 0 including 0 are all whole numbers, while the integers on the right side of 0 excluding 0 are all natural numbers. This graphic representation is the most effective way to demonstrate that all natural numbers are whole numbers but not vice versa.
