A clothing store has a sale on T-shirts. The shirts come in small, medium, and large sizes and can be red, black, or white. How many different combinations of shirts are available?

So an easy way to actually see that is to do this:
So for the small, there will be three combinations. And if you do that with the mediums, six combinations. If you do that with the larges, nine combinations. You multiply.

Yeah. So if there are 3 sizes and 3 colors, you do 3*3 = 9 total combinations. Or you can add, like I just showed in the picture.
