2014 From June 13 to July 13, Brazil will host the World Cup. By then, 32 teams will be divided into 8 groups on average, and each group will play a single round robin. The top two teams qualify, and the qualified 16 team will decide the final champion, runner-up and runner-up in a single knockout. How many games will there be in the World Cup?

Math problem solving: divided into 8 groups on average, then each group has a group: 32 ÷ 8 = 4 (branch).

If a single cycle is performed in a group, each group will play one game: 3+2+ 1 = 6 (field).

8 teams * * * battle: 6× 8 = 48 (field)

In the case of further elimination, it will be compared with: 16 in 8 ... 8 games, 8 to 4...4 games, 4 to 2...2 games, champion and runner-up ... 1 game, 1 game, and one * * game: 8.

World Cup matches1* * are: 48+ 16 = 64 (matches).
