## Introduction

In this lesson, you will learn about the P.E.M.D.A.S Method. This method is used when simplifying algebraic expression. This topic will teach what each letter stands for and a few tips and tricks on how to remember and order P.E.M.D.A.S. So let's get started!

## P.E.M.D.A.S

P.E.M.D.A.S. stands for the following:

• P is for Parenthesis
• E is for Exponents
• M is for Multiplication
• (left to right)
• D is for Division
• (left to right)
• S is for Subtraction
Keep in mind that for multiplication and division and also for addition and subtraction, you have to solve from left to right.

The best way to remember  P.E.M.D.A.S. is by remembering the following sentence:

Please Excuse My Dear Aunt Sally

Now, that you know what P.E.M.D.A.S. stands for, let's solve an algebraic expression using P.E.M.D.A.S.

(5 x 3)+14/7-6

According to P.E.M.D.A.S. Parenthesis comes first.

(5 x 3)+14/7-6
15+14/7-6

Next, is exponents but since we don't have any exponents in this, we'll just move on to Multiplication and Division from Left to Right. We only have division.

(5x3)+14/7-6
15+14/7-6
15+2-6

Now, we just have to add or subtract from left to right.

(5x3)+14/7-6
15+14/7-6
15+2-6
17-6
