Lesson Summary:

In this lesson, students learn how to simplify expressions using the order of operations, also known as PEMDAS. The teacher walks through the steps of solving an example problem, demonstrating the importance of doing operations inside parentheses first, then following the order of operations by performing multiplication and division before addition and subtraction. Students are reminded to work from left to right when performing operations of the same priority. By the end of the lesson, students will have a solid understanding of how to properly evaluate expressions using the order of operations.

How to simplify an expression using PEMDAS with Brackets

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.
