1. Lesson 1 - Irrational Numbers

2. Number Systems Natural Numbers: N = { 1, 2, 3, …}
Whole Numbers: W = { 0, 1, 2 , 3, ...}
Integers: I = {….. -3, -2, -1, 0, 1, 2, 3, ...}

3. Number Systems Cont… Rational Numbers:
Irrational Numbers: Q = {non-terminating,
non-repeating decimals}
Real Numbers: R = {all rational and irrational}
Imaginary Numbers: i = {sq. roots of negative numbers}
Complex Numbers: C = {real and imaginary numbers}
