The gym is sponsoring a basketball elimination tournament with 16 teams entered. Winner play winners until only one team is left. What is the total number of games that must be played?
First round: 16 teams --> 8 games
Second round: 8 winners --> 4 games
third round : 4 winners --> 2 games
Championship : 1 game
What is 1+2+4+8 ?
