# Order of Operations

## PEMDAS

In the Order of Operation you use PEMDAS to figure out your equation. The **P** stands for **P**arentheses, since the** P** comes first in PEMDAS do the **P**arentheses first. Next, do **E**xponents,** **for the **E. **Then, do any **M**ultiplying or **D**ividing for the **M **and** D**, if there is both do what comes first going left to right. Lastly, do any** A**ddition or **S**ubtraction for the **A** and the **S**, same with this if there is both or more than one do what comes first going left to right. Congratulations! You now know PEMDAS.

## Time for a Example!

Let's start with a equation: 8x(9+17)-9+21

If we are following PEMDAS, we have to do the **P**arentheses

9+17=26

Now the problem looks like this: 8x26-9+21

Since there are no **E**xponents go to the **M**ultiplication or** D**ivision.

For the Multiplication part in the problem we now multiply 8x26=208.

Now the problem looks like this: 208-9+21

If you are following PEMDAS, **A**ddition and **S**ubtraction is next in left to right order.

In this problem in left to right subtracting 9 from 208 is next, 208-9=199.

Now the problem is 199+21.

There is only one more thing you have to do in this equation is simple **A**dding, 199+21=220.

Now you know how to solve a problem and use PEMDAS!
