### Unit 4: Inequalities

You probably use inequalities, just like equations, in everyday life without thinking about it. Every time you go to the store, you need to decide whether you have enough money to pay for the items you need to purchase. The inequality you need to solve is the Amount of Money has to be GREATER than the Total Cost of Items. In this unit, very similar to Unit 2: Equations, you will generalize the procedure for solving inequalities. You will learn that an inequality is a statement and its solution is a set of numbers that makes this statement true. You will explore which properties of inequalities are the same and which are different from the properties of equations.
