Note: Many problems in this packet will be completed together in class during review time. Students are not expected to complete every single problem in the packet. They should complete several problems from each page-- in addition to studying the notes and past quizzes– in order to be fully prepared for test. TOPICS COVERED ON “The language of algebra” TEST :  Order of Operations  Evaluating Algebraic Expressions (substituting numbers for variables)  Translating Algebraic Sentences  Properties (Commutative, Associative, Distributive, Identity, Inverse, and Zero Properties)  Vocabulary: Algebraic Expression v. Equation Constant Coefficient Variable NOTES SPACE/HELPFUL TIPS (to be filled out in class): Name:__________________________________________________________________________________Date: _____/_____/__________
