Natural numbers and Whole Numbers: What is difference between them?

Most students get confuse with Natural numbers and Whole numbers. I hope this tutorial will get rid of this confusion.

Now, the set of Natural numbers (N) is given by: N= {1, 2, 3, 4 ...} and the set of Whole numbers (W) is given by: W = {0, 1, 2, 3, 4 ...}. Thus the intersection of N and W = N and the union of N and W = W.

The smallest natural number is 1 and there is no largest natural number.

The smallest whole number is 0 and there is no largest whole number.
