"There are 93 players signed up for a single elimination tennis tournament. How many matches will be played in all?"

Question

How would you go about solving a problem like this? I am confused.

Answer 1

This problem can be solved any effort at all. All you have to do is realize that in each match one player is eliminated. When the tournament is over there is one winner, so 92 players have been eliminated, therefore 92 matches will be played.
