The formula N=t^2-t/2
The formula describes the number of football games. N, that must be played in a league with t teams if each team is to play every other team once.
Solve equation below
If a league has 36 games scheduled, how many teams belong to the league, assuming that each team plays every other team once ?
-----------
N(36) = 36^2-(36/2)
= 1296 - 18
= 1278
