Integers are the set of all positive and negative numbers including zero. They are denoted by Z, i.e. z= {........, -4, -3, -2, -1, 0, 1, 2, 3, 4 ..........} 

All the natural numbers are integer but converse is not true. e.g. 2000005 is a natural number and integers. On contrary (-5) is an integer but not a natural number.

Similarly whole numbers are integer and converse is not true.
