anonymous · Answer

4 teams... 3 games with each other makes it 9 multiplied by 4 (the number of teams) = 36 that's the way i learnt it @satellite73

@Adrian7   I think you are double counting the games.  when team 1 plays team 2, that is the same game as when team 2 plays team 1.  If you list 4 teams, and all the games for 1 round, you will get 6 games.
