To find out how many more saxophone players there are than tuba players, we need to subtract the number of tuba players from the number of saxophone players. In this case, there are 32 saxophone players and 10 tuba players.
So, we would solve the problem as follows:
32 (saxophone players) - 10 (tuba players) = 22
Thus, to fill in the blank in the sentence, it should read: "To solve this problem I subtract 32 people with 10."
