Hi, sry, forgot to divide by 2.

*Note: Each player plays 10 matches
There are 11 players total
In general, If n is the number of competitors, a pure round robin tournament requires (n/2)(n-1) games. 
(If n is even, then in each of (n &#8722; 1) rounds,  n/2 games could be run in parallel.
If n is odd, there will be n rounds with (n-1)/2 games and one competitor having no game in that round.)

110/2 or 55 matches will be played in this round robin tennis tournament
