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
- A is for Addition
- (left to right)
- S is for Subtraction
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
