all the number sets we have seen above put together comprise the real numbers real numbers are also inadequate in the sense that it does
the set of whole numbers also does not satisfy all our requirements as on observation we find that it does not include negative numbers
observe that natural numbers do not have a zero this shortcoming is made good when we consider the set of whole numbers the
to begin with we have counting numbers these numbers are also known as natural numbers and are denoted by a symbol n these
