Lesson Summary:

In this lesson, the instructor goes over how to evaluate expressions with three variables by using specific values for each variable. The key takeaway is to remember to follow PEMDAS rules, including working on parentheses, exponents, multiplication and division, and addition and subtraction from left to right. By plugging in the values for each variable into the expression, students can simplify and determine the final value of the expression.

Lesson Description:

Evaluating an expression with three variables

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.
