0Number System:
There are two majaor division in the Number System
i.e.
1. Real Number System
2. Complex Number System
Real Number System: (SYMBOL Is "R")
It is a set that contains following sets as subset
Natural Numbers: N = {1, 2, 3, ...}
Whole Numbers: W = {0, 1, 2, 3...}
Integers: Z = {..., -2, -1, 0, 1, 2,...}
Rational Numbers: Q = {p/q : p,q∈Z, q≠0}
Irrational Numbers: π (pi), e, and square root of natural numbers which are not a perfect squares
Note:
N ⊂ W ⊂ Z ⊂ Q ⊂ R
