In this video, we will be learning how to solve equations using order of operations.

Use** PEMDAS**:

**P**arenthesis

**E**xponent

**M**ultiplication

**D**ivision

**A**ddition

**S**ubtraction

## Examples of Order of Operations

### Example 1

First, we will solve the number with exponent

Then, we will divide 28 by 4

Now, we add the two numbers

Therefore, the answer

### Example 2

First, we subtract the numbers inside the parenthesis

(16-4)+3\times2=(12)+3\times2

Then, we multiply 3 and 2

(12)+3\times2=12+6

Now, we add 12 and 6

Therefore, the answer

## Video-Lesson Transcript

In this video, we will be learning how to solve equations using the order of operations.

PEMDAS stands for:

Parenthesis

Exponent

Multiplication

Division

Addition

Subtraction

Multiplication and division can be interchanged. Whichever of the two comes first.

Same is true for addition and subtraction.

Square root has the same order as the exponent.

While the absolute Value Bars have the same order as the parenthesis.

Let me give you an example.

We have

First, do the operation inside the absolute value bars first.

Some would think that it would be

But it is not.

Let’s do

Here, we should compute the first.

We will come up with

So it will be

And the answer is

Notice that if we keep this

The answer wouldn’t be the same.

Let’s move on to square roots.

We have

We can’t just add these together.

We have to do the Exponent first.

So, it’s going to be

Add these and we’ll have

So there you have it.

Again, treat square root with the same order as exponent.

And absolute value bars with the same order as the parenthesis.
