Whole Numbers

Whole numbers are the natural or counting numbers (1, 2, 3 and so on through infinity) plus the number zero.

The number zero is a relatively recent innovation. There is no Roman Numeral zero, for example. See http://en.wikipedia.org/wiki/0_%28number%29#History for more details.

Add the zero to the counting numbers and you have whole numbers.
