Number of matches: The number of matches in a single cycle can be calculated by the following formula (simple mathematical combination formula):
Number of matches = number of teams * (number of teams-1)/2 If 6 or 7 teams participate in the match, the number of matches is: 6 *(6- 1)/2 = 15 (field) 7 * (7- 1)/2 =.
So, a total of 10 teams participated!
You can set x pairs of participation equations, x(x- 1)/2=45.
