Question: Math question need help with a word problem and getting an equation?

In a baseball league consisting of 10 teams, each team plays each other teams twice. How many games will be played?

Answer: How many teams much a given team play? There are 10 teams, each team must play 9 other teams.
10 x 9 = 90. To get the number of games if each team played each other once you would have to divide by 2 (since the game in which Team A plays Team B is the same game in which Team B plays Team A, and for any possible combination of two teams a similar duplication exists.

So, for a league of 10 teams, 45 games are required for each team to play each other once, and for each team to play each other twice you need to double this number, giving you a final answer of 90.

In fact, for any competitions where there are n teams, and they each play each other x times, then the number of matches in the competition is xn(n-1)/2.
