Algebra 2 Week #1A Section 1 Just so you know. Week #1A – Section 1 GOAL: To review integer arithmetic rules and true/false statements. (Preliminary Review) CA ALGEBRA 1 STANDARD 1.0: To use the arithmetic properties of integers, and to demonstrate that assertions are true or false. • WARMUP QUESTIONS • • Evaluate: 1. 22 + 42 = ______ • 2. 52 + (-2)2 = ______ • 3. (-1)2 + 12 = ______ • 4. (-5)2 + 0 = _____ • 5. - 6 – (- 5) = ________ Week #1A – Section 1 GOAL: To review integer arithmetic rules and true/false statements.

Different signs: Add/Subtract 1. Same signs: 2. Different signs: Week #1A Section #1 Notes Integers and True/False Statements The Questions • • • • • • • 1. WHAT are the rules for integer arithmetic? Multiply/Divide 1. Same signs: Positive answer 2. Different signs: Negative answer Add/Subtract 1. Same signs: 2. Different signs: Week #1A Section #1 Notes Integers and True/False Statements The Questions • • • 1. WHAT are the rules for integer arithmetic? Multiply/Divide 1. Same signs: Positive answer • 2. Different signs: Negative answer • • Add/Subtract 1. Same signs: Add numbers, keep sign • 2. Different signs: Subtract numbers, keep sign of larger Week #1A Section #1 Notes Integers and True/False Statements The Questions • 2. WHAT kind of answer should you ALWAYS have for a evaluate problem? 3. WHAT are true or false statements? Week #1A Section #1 Notes Integers and True/False Statements The Questions • • 2. WHAT kind of answer should you ALWAYS have for a evaluate problem? A number 3. WHAT are true or false statements? Week #1A Section #1 Notes Integers and True/False Statements The Questions • • 2. WHAT kind of answer should you ALWAYS have for a evaluate problem? A number 3. WHAT are true or false statements? A true statement is an equation that is the same thing on both sides. (Like 4 + 1 = 5) With a false statement, the sides are different. (Like 4 + 1 = 6) Algebra wants to know. Do you know?
