Natural numbers along with zero (0) are referred to as whole numbers. We know that natural numbers refer to a set of counting numbers starting from 1, 2, 3, 4 and so on. In simple words, whole numbers are a set of numbers without fractionsdecimals, or even negative integers. It is a collection of positive integers and zero. Or we can say that whole numbers are the set of non-negative integers. The primary difference between natural and whole numbers is the presence of zero in the whole numbers set.
