In this lesson, you will learn how to write an expression from a word problem. Using a used book store as an example, the teacher explains how to identify variables and what they represent, as well as how to determine the constant cost of each item. By adding the expressions for the cost of buying hardcover books and paperback books, you can calculate the total cost of buying any combination of books.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework.
