1) Count the total number of games that each team plays; then, since that counts each game twice, divide by 2:

(number of teams) times (number of opposing teams) times (number of times per season)

6*5*9 = 270

then divide by 2

270/2 = 135

OR, to be a bit more sophisticated mathematically....

(2) Determine the number of pairings and multiply by the number of times per season that each pairing occurs:

(6 choose 2) times (number of times per season)

6C2 * 9 = 15*9 = 135
