When we select a set of natural numbers and set of whole numbers to compare, we find that both the lists are different in one aspect. What is that aspect? Is our observation correct?
Natural number are the ones which starts with 1,2,3.... and goes on whereas the set of whole numbers start with 0, 1,2,3.... and goes on. The only difference in their set is the number 0, whole numbers have 0 and natural numbers do not. Natural numbers are also called counting numbers as they are the most commonly used numbers in our daily life, counting starts with the number 1. The set of both natural and whole number does not contain negative numbers, they are a set of non negative numbers.
