In this lesson, you will learn why we combine like terms and how to simplify them. Like terms are terms that are exactly the same, such as 3x and 5x. By grouping them together, we can combine them to get a simpler expression. It's important to remember to only combine terms that are like, and not try to combine terms that are different. With practice, combining like terms will become second nature!
Simplifying why we combine like terms
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.
