Natural Numbers(N): Natural Numbers are counting numbers from 1,2,3,4,5,................
N = {1,2,3,4,5,................}
Whole Numbers (W): Natural Numbers plus zero. Whole Numbers are 0,1,2,3,4,5,...............
W = {0,1,2,3,4,5,..............}
W = 0 + N
Positive Numbers:
Positive numbers are, 1,2 ,3 ,4 ,5.................
Positive Numbers: {1, 2, 3, . . .}
Negative Numbers:
It is a number that is less than a zero.
Negative numbers are, ............3, 2, 1.
Negative integers: { . . . 3, 2, 1}
Integers (Z):
 Whole Numbers together with negative numbers.
 Integers are set containing the positive numbers, 1, 2, 3, 4, ...., and negative numbers,............3, 2, 1, together with zero.
 Zero is neither positive nor negative, but is both.
 In other words, Integers are defined as set of whole numbers and their opposites.
 Z = {..., 3, 2, 1, 0, 1, 2, 3, .....}
Example:
