How is the Serie A game played?

There are 20 teams at home and away, which means that each team plays 19 at home and 19 away.

***38 games a season.

Win a game with 3 points, draw a game 1 point, lose a game with 0 points, and then accumulate. The more scores, the better the ranking.

Which round means which game?

The specific schedule, which round to play is arranged by the Italian Football Association.

I don't know what you mean by permutation and combination kick. Is it possible to meet any of the 38 games in the first round? Suppose it is a game against A, then the second round will avoid A, so we will take any of the other 36 games.

So the combination of the first two games is 38*36.

Is that what you mean?

I got so many points, you must give it to me. Ask me if you don't understand.
