Chapter 402 They can't keep up with Teacher Chen's train of thought now.

The competition venue of the International Mathematical Olympiad is very large. They first took a look at the competition venue and then came to the waiting room prepared for them.

In the rest room, the two team leader teachers explained the rules of the game for them again. Although they emphasized it every day, they still had to tell them about this scene.

"The test is divided into two days, with three questions for 4.5 hours a day. The six players of the same team are assigned to six different test rooms to answer the questions independently. The answer sheets are judged by the team leader of the country, and then the coordinator designated by the organization Negotiate, if there is any disagreement, please ask the main test committee for arbitration, each question is 6 points out of 6 points."

"Then for imagination, there will be a first prize medal, a second prize silver medal, and a third prize bronze medal. The ratio is about 1:2:3."

"Speaking of which, have you heard clearly? And if you can get the first prize, you can play freely in this country for the rest of the summer vacation."

After listening to the words of the two team leaders, especially the last sentence, everyone's fighting spirit was aroused. Their goal is the same as that of other countries, which is to win the first prize medal.Although they were a little more selfish than others, they did not destroy their ultimate goal, but rather aroused their interest in the goal again.

After getting ready in the lounge, it was time for the game to start.All of them left the waiting room and headed to the playing field.

"Now all the contestants are in place, and the competition will start soon. Please get ready."

After another 5 minutes after this block, the game officially started.

"Okay, now the competition officially begins, please enter each competition room separately."

Lin Sheng and He Yang respectively entered the rooms that were closer to each other.

They got the topic of the International Mathematical Olympiad Competition in their hands respectively.

The content of the first question is: use Z to represent the set of all integers, find all functions F equal to Z→Z satisfying that f(1a)+2f(b)=f(f(a+ b)).

This question first stumped a small number of people, those who find it difficult to find sets.In fact, when they saw this question, Lei Sheng and He Yang hesitated. Although the number of times this question was relatively small, it was a little bit beyond their expectations.

But after reading the question several times, the two of them had the answer, and began to immediately write the answer to the question on the test paper.

Although the remaining questions were somewhat difficult, the two of them quickly answered them, and they were the fastest in the examination room.Of course, in addition to speed, the words here still pay attention to accuracy.

Here, the accuracy rate represents the strength, and the speed does not represent everything.

The first day's exam officially ended in the afternoon, and everyone handed in their test papers and waited for the results to come out later.

Except for Lin Sheng and He Yang, everyone in the team didn't have much confidence in themselves, and they all wondered if their results this time were bad.Because this year's questions are really a bit difficult and different from the test questions they did before, it can be said to be the most difficult in the past few years.

"Okay, cheer up, everyone, there is another exam tomorrow. After this time is over, if you can get the gold medal, everyone can play here. You just need to think about this." .”

All of them were silent, because they didn't know why Teacher Chen would say this.

No, Mr. Chen, why do you think we will win the gold medal this time?Are you a little too confident in us...

They can't keep up with Teacher Chen's train of thought now.
