Write a 150 word journal about the World Cup

When the South Korea-Japan World Cup was in full swing, did you notice that there were many math problems in the World Cup? If you don't believe me, you look down.

In the group stage of the World Cup, every four teams play a single round-robin match, with the winning team receiving 3 points, the losing team scoring 0 points, and the draw team scoring 1 point each. At the end of the group stage, the two teams with the highest total points qualify and advance to the next round of matches. If the total points are the same, further rules are also used.

The 4-team round-robin matches are required to play 6 games, with a maximum of 3 points per game and a maximum of 18 points for 6 games.

If a team has 6 points, they have 12 points left, and there may be two other teams with 6 points each, so they will be sorted according to further rules, so the team may not qualify.

I figured it out: if a team has 7 points, there are 11 points left, so that it is impossible for two of the other three teams to have 7 points equal to or more than 7 points, so that team will definitely qualify. Therefore, in order to advance to the next round, a team must have at least 7 points to ensure that it will definitely qualify.

Question 2: If a team only has 3 points, is it possible for this team to qualify?

It's possible. All six matches were draws, with all four teams scoring just three points, and in further order of the rules, the team could qualify if they were in the top two.

There is another situation, can you think of it?

Think about it: (1) If a team has 5 points, can the team qualify? Why?

2) If a team has 2 points, can the team qualify? Why?

Children, have you ever thought about these questions in the process of the World Cup? In fact, mathematics is everywhere in life, as long as everyone pays attention to it, you will have a lot of gains.

This summer, the World Cup quietly left with the heat of samba and the shouts of the fans, and it left us with miracles one after another, such as the uncrowned 5:1 defeat of the Bullfighting Army, and the 7:1 draw of the will chariot with the five-star Brazil.
