## Introduction: Simplifying an Expression

After going through these steps you should know how to simplify an expression and use a calculator to check your answer.

## Step 1: Rules

The order in which we evaluate expressions can be ambiguous.

## Step 2: First Step

Because of the exponent we must compute it first. Notice that we are really just multiplying 2, six times.

## Step 3: Step 2

Now we multiply more. In general we should be starting from the left and then working our way to the right, but because of notation we start with the exponent.

## Step 4: Step 3

Remember to start adding and subtracting from the left and work you way to the right.

## Step 5: The Calculator Uses Order of Operation

So we always can check our answer by using a calculator.

## Step 6: Now You Try!

You have the tools. Now it is up to you to use them.

## Step 7: Answer

If you got the answer right, Wonderful! If not, keep trying!

## Step 8: Calculator

Did you check your answer using a calculator?
