M在举行门球循环赛时,一个场地的比赛场数,是运用这样的公式计算:场数=参赛队数×(参赛队数-1)÷2如,有9个队参赛,场数应为:9×(9-1)÷2=72÷2=36(场)其实,在计算时可采用一种简便方法:如果参赛队数是奇数,如上例为9个队,那么每队应当有(9-1)8场球,通过口算,用8除以2,等于4;用4 M In the goalkeeper round robin, the number of matches at a venue is calculated using the following formula: Number of Teams = Teams × (Teams -1) ÷ 2 If there are 9 Teams competing, the number of Teams should be (9-1) ÷ 2 = 72 ÷ 2 = 36 (field) In fact, a simple method of calculation can be used: If the number of teams is an odd number, as in the previous example 9 teams, then each team should have (9-1) 8 games, through the mouth count, divided by 8 by 2, equal to 4; with 4
