In this lesson, you will learn how to solve one-step word problems using algebraic expressions. The instructor uses the example of two people with different numbers of CDs to explain how to pick a variable to represent the unknowns and create an expression for each. By setting the two expressions equal to the given total and simplifying, the variable can be solved for, revealing the number of CDs each person has. This method can be applied to a variety of one-step word problems.
Solving a one step word problem
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. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
