At Tubman Middle school there are 7 English teachers and 6 science teachers. If each student takes one English class and one science class, how many possible combinations of teachers are there?

7 English and 6 Science

There are 7 * 6 ways this can be put together. Which makes 42.

Take a look at the diagram below. There are 6 possible science teachers that the student could choose after choosing E1 which is the first English teacher. Each of the remaining 6 english teachers also allow for 6 science teachers.
