Real Numbers Natural Numbers naturally what babies start with (counting) Whole Numbers natural numbers and zero. Integers - natural numbers, zero, and negative integers. Each negative integer is the additive inverse (or opposite) of a positive integer
Real Numbers Rational Numbers -all numbers that can be written as quotients (division) of integers. - can be terminating decimals or repeating decimals. Irrational Numbers - cannot be written as quotients of integers - decimal representations neither terminate or repeat (like pi). - if positive rational number in not a perfect square root such as 25 or then, its square root is irrational.
