Algebra 2 Unit 2 Lesson 2

Additive Inverse : The opposite of a number a is -a

multiplicative inverse : Two numbers with a product of 1. any nonzero number n is 1/a. ex. -5(-1/5) =1

communitive property of multiplication : a x b = b x arearrange problems to make them easier to solve

Assosiative Property of addition : (a+b)+c=a+(b+c) changing or grouping numbers differently wont effect the outcome
