(2) Explain why one answer to the counting problem is A. (3) Explain why the other answer to the counting problem is B. Since both A and B are the answers to the same question, we must have A=B. The tricky thing is coming up with the question.

We have already learned to multiply binomials and to raise binomials to powers, but raising a binomial to a high power can be tedious and time-consuming. In this section, we will discuss a shortcut that will allow us to find (x+y)n without multiplying the binomial by itself n times.

We will give an example of each type of counting problem (and say what these things even are). As we will see, these counting problems are surprisingly similar.
