# Whole Numbers, Definition Of Whole Numbers

## What Are Whole Numbers?

**Whole Numbers** are 0, 1, 2, 3, ... infinity, and are Integers.

Whole numbers are represented by the digits from 0, 1, 2, 3 through to infinity. In math, there are an infinite number of whole number digits. Each number is defined by having a number before it and following it. A simple example: 9, 10, 11, ... infinity; 9 is before 10 and 11 is after 10 so on forever.

There is one important fact that makes whole numbers uniquely different from Natural Number: Zero is a whole number.
