Chapter 2: Simplifying with VariablesFocusing on Variables
This chapter begins with a focus on the use of variables, such as x and y. First, you will use tools called “algebra tiles” to explore how and where to use variables. You will write expressions and then learn how to write them in the most efficient way. Later in the chapter, you will learn how to compare two expressions to determine which one is greater. This will lead to a process of recording your steps so that anyone can understand your work. Finally, you will look at what happens when you cannot tell which expression is greater and consider the question, “What if they are equal?” Since the topics in this chapter lay the foundation for simplifying expressions and solving equations, they will be revisited and built upon throughout the course.
