In this lesson, the instructor teaches how to simplify an expression using the order of operations. The first step is always to evaluate any content within the parentheses before proceeding with multiplication, division, addition, or subtraction. The instructor emphasizes that it is crucial always to follow the correct order to end up with the correct answer.
Using order of operations to simplify an expression
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.
