You have used many powerful tools, including graphs, tables, and equations, to represent relationships among variables. Graphs allow you to see the shape of a relationship. They also help you identify intercepts and maximum and minimum points. Tables help you observe patterns of change in the values of the variables. Equations give you an efficient way to generalize relationships. In Say It With Symbols, you will concentrate on symbolic expressions and equations. You will see that different ways of reasoning about a situation can lead to different but equivalent expressions. You will use mathematical properties to rewrite expressions, and you may discover that an equivalent expression allows you to think about a problem in a new way. And, you will learn new ways to solve equations. Pools are used as a context throughout this unit to introduce these ideas.
