# When to do What

The first step in interpreting word problems is to understand what each of the four basic operations mean. Not knowing HOW to add, subtract, multiply, and divide- rather knowing WHEN.

## STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES

### Make sure to note the following:

The four basic operations are addition, subtraction, multiplication and division. It is crucial that you can correctly identify the appropriate operation in the real-world scenarios presented in GED word problems.

### Print out these example problems to follow along with the video.
