Question 559730
This would probably be classified in a field of math called "combinatorics."


Each team plays 7 games, so intuitively the number of games would be 8*7 = 56. However, we are counting each game twice (e.g. team 1 & team 6, team 6 & team 1) so we divide by 2 to get 28. Using combinatorics, the number of games would be 8C2 = 8*7/2! = 28.
