Natural numbers along with zero (0) are referred to as whole numbers. We know that natural numbers refer to a set of counting numbers starting from 1, 2, 3, 4 and so on. In simple words, whole numbers are a set of numbers without fractions, decimals, or even negative integers. It is a collection of positive integers and zero. Or we can say that whole numbers are the set of non-negative integers. The primary difference between natural and whole numbers is the presence of zero in the whole numbers set.

Whole Number Definition

Whole Numbers are the set of natural numbers along with the number 0. The set of whole numbers in mathematics is given as {0, 1, 2, 3, …} which is denoted by the symbol W.

W = {0, 1, 2, 3, 4, …}

Here are some facts about whole numbers, which will help you understand them better:

• All natural numbers are whole numbers.
• All counting numbers are whole numbers.
• All positive integers including zero are whole numbers.
• All whole numbers are real numbers.

Whole Number Symbol

The symbol used to represent whole numbers is the alphabet ‘W’ in the uppercase, W = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, …
