The smallest whole number is zero. The set of whole numbers includes all natural numbers and the number 0. There is not a largest whole number, as the set of whole numbers is infinite.

The set of whole numbers is represented by the symbol W. This set is given as follows: W = {0, 1, 2, 3, 4…}.

The set of natural numbers is represented by the symbol N. These numbers are referred to as counting numbers. This set is given as follows: N = {1, 2, 3, 4…}.

Whole numbers are all positive numbers. All natural numbers are whole numbers, but not all whole numbers are natural numbers.
