1. given a nonzero rational number a/b, the reciprocal, or multiplicative inverse is b/a The product non of a non zero number and it’s reciprocal is 1.
2. a number that is multiplied repeatedly
3. a number that shows repeated multiplication
5. an equation that contains one or more variables
7. a term that has no variable factor
9. a real number that can be written as a quotient of two integers where the denominator is not 0. Rational numbers in decimal form are terminating and repeating.
10. replace an expression with it’s simplest name
12. a number that cannot be written as a ratio of two integers. Irrational numbers in decimal form are nonterminating and nonrepeating
