If both classes contain 167 students then we add them 167+167= 334
If you're doing addition, you will add 167 and 167.

167 + 167 = 334

If you're doing multiplication, you will multiply 167 by 2.

167 * 2 = 334

There are 334 third and fourth graders.

Hope I was able to help :) if you have any questions, just ask.
