1 Organizing Numbers into Number Sets

2 Definitions and Symbols for Number Sets Counting numbers ( maybe 0, 1, 2, 3, 4, and so on) Natural Numbers: Positive and negative counting numbers (-2, -1, 0, 1, 2, and so on) Integers: a number that can be expressed as an integer fraction (-3/2, -1/3, 0, 1, 55/7, 22, and so on) Rational Numbers: a number that can NOT be expressed as an integer fraction (π, √2, and so on) Irrational Numbers: NONE

3 Definitions, Symbols, & Venn Diagram for Number Sets The set of all rational and irrational numbers Real Numbers: Natural Numbers Integers Rational Numbers Irrational Numbers Real Number Venn Diagram:
