Whole Numbers are combination of Zero and natural numbers. They are 0, 1, 2, 3, 4, 7..., and so on are called counting numbers, or natural numbers. They are called counting numbers because each counting number can be used to count physical objects.

For example we can label each of the blocks by a counting number to find out how many blocks we have. Therefore, the counting numbers can be shown as the set { 1, 2, 3,. . .

Also, it is to be noted that all natural numbers are whole numbers, but not all of them are natural number. Because, the number zero is known as a natural number. In this module one can detect how a number can be classified as more than one type. For example, the following numbers 2, 3, 4,5, 6, etc, can belong in both categories. Arithmetic, is known as the science of numbers.
