I was taught three types of numbers that have no fractional parts:

integers, from negative infinity up to zero then up to positive infinity.
natural numbers, the non-negative integers 0,1,2,3,...
whole numbers, the positive integers 1,2,3,...

Hi Mathfan,

A whole number is any number that is zero or greater but is not a fraction or decimal.

One way of thinking of whole number is that it's "whole" because it's not a part of something.  For example, the number 24.5 is not a whole number (it's a decimal or fraction) because it's a part of a larger number.  On the other hand, the number 25 is a whole number.

Another way of thinking about whole number is if you can form that number using just dollar bills without change then that is a whole number (remember to include zero though).

Hope this helps!
