How many games are played in a 12 team division?

In a 12-team division, if each team plays every other team once, a total of 66 games are played. This is calculated using the formula for combinations, where the number of games is ( \frac{n(n-1)}{2} ), with ( n ) being the number of teams. For 12 teams, it’s ( \frac{12 \times 11}{2} = 66 ). If teams play each other multiple times, the total number of games would increase accordingly.
