1. Solving Inequalities Using Multiplication and Division Chapter 4 Section 3

2. Pg 212 Multiplication Property of Inequality for c > 0 Pg 213 Multiplication Property of Inequality for c < 0 Pg 214 Division Property of Inequality for c > 0 and c < 0

3. Follow the rules for solving equations with 3 exceptions 1) When you multiply both sides of an inequality by a negative # you must reverse the inequality sign 2)When you divide both sides of an inequality by a negative # you must reverse the inequality sign 3)When you multiply both sides of an inequality by 0, it becomes an equality
