In this lesson, you'll learn how to simplify expressions using the order of operations or PEMDAS. By starting with the operations inside parentheses, then handling exponents, followed by multiplication and division, and finally ending with addition and subtraction, you can avoid common mistakes and get the right answer every time. Remembering the acronym PEMDAS can help you keep the order straight, ensuring that you always follow the right steps in the right order.
Simplifying an expression with four operations
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.
