Chapter 24-This Child Can Be Used
The thing he hated the most was disturbing him when he was playing games. Of course, if his teacher was looking for him, he would tell him something else.
"The core of this question is actually the development of logical thinking. You have to remember that the core of Mathematical Olympiad is thinking. In fact, the essence is still mathematics. Of course, remember that Mathematical Olympiad and International Olympics cannot exceed high school knowledge points.”
Chen Fan naturally had to listen carefully to the teacher's lecture, but this did not affect Chen Fan's two-pronged operation.
"You guys should get to know each other. When the time comes, you'll be a team. Helping each other is the core. Also, Chairman Zhou, you should work harder and do more questions. There are two gold medals in the individual competition and the team competition.”
Chairman Zhou naturally understood what he meant. The other five people all got full marks or close to full marks, except for him.
Only twenty points, and of course, Chen Fan also had twenty points.
Of the seven people in the video, the other five were rather dull. Three were boys and two were girls.
The questions given by the teacher were answered by the other five people in about five minutes. Chairman Zhou took about ten minutes.
If he wasted time because of Chairman Zhou, it would be unfair to the other five.
"Teacher, please tell me. There's a video here. I'll prepare for it myself later. Don't delay other people's results because of me.”
What a good boy. To be honest, among these people, Qian Donghai liked Chairman Zhou the most. He was the most suitable for academic research, but he was a little stupid.
"Alright, I'll teach you something different first. I'll teach you the solution to the Spica equation.”
Qian Donghai had been preparing for a long time. This year was a military year. It could be said that many people cared about this matter. It had been a long time since they had won the Mathematical Olympiad championship. This was unacceptable to China.
Therefore, everyone was working extra hard this year.
Chen Fan yawned. It took him about three minutes to understand what the teacher was talking about. Basically, he had just written the beginning of the equation solution. Chen Fan's eyes lit up slightly and he realized it.
Ding! You have received guidance from an expert. Your mathematics foundation has improved.
This kind of fulfilling feeling was actually quite good.
Chen Fan was like a martial arts master who suddenly gave him a hundred years of cultivation strength. He had to figure out how to use it.
And replenishing the foundation was a good solution to this kind of awkwardness.
It wasn't that Chen Fan didn't listen, but he understood faster.
Yang's triangle, the Diesro function, the meaning of splitting a linear curve, and so on.
Qian Donghai wished he could give everything to these students, hoping that they would be able to learn everything.
"There are a few questions here. You guys calculate first and see the effect.”
Chen Fan could play for a long time.
It was a powerpoint presentation with a total of three questions. Chen Fan spent some time, about ten minutes, to answer them.
It wasn't that he didn't know how to do it, but these questions were a little long. It would take time to find the conditions from them.
This time, Chen Fan didn't send it to the group. Instead, he wrote it and put it aside.
This time, Chen Fan did not open the game because Chairman Zhou was looking for him.
"Chen Fan."
"Big brother, what is it?"
"You can be the main force. I know you have the ability. You probably don't want to be too famous and like to keep a low profile.”
"Then my stomach hurts, but you still have to go up, don't you?”
Chairman Zhou sighed helplessly and said,"In the past, I also controlled my points, but later on, I realized that after I used my full strength, I actually didn't get first place. That's why I started to study seriously.”
"Don't talk nonsense. I'll sue you for slander.”
" I want to study mathematics, but I'm not talented. I can only do the questions, but I feel like I'll be a burden this time. Let me ask you, Chen Fan, if we were to participate in the competition this time and were eliminated in the preliminary round because of my failure, how do you think they would scold us?"”
Chen Fan was just about to open the Cloud Top to play chess when he stopped.
It seemed to make sense.
"Hmm…what you said is indeed a problem. How do you want to deal with it?”
"You go and participate in the competition. I'll be a substitute. You go all out and don't control your points.”
"No, I can get as many marks as I want. That's my freedom. Why should I listen to you? The more you say that, the more I won't listen to you.”
Chen Fan began to think.
Chen Fan was a lazy person, and people would instinctively think that it would not be so troublesome.
The system didn't give him any tasks at the moment, and he was only a substitute, so Chen Fan naturally wouldn't waste too much time. However, since Chairman Zhou was begging him, Chen Fan decided to help him.
However, based on what Chairman Zhou had said, Chen Fan felt that this group of people were a little noob.
"Teacher, I saw a question here. I want everyone to sit together. I think it's quite suitable.”
A question?
Qian Donghai looked at Chen Fan's camera in surprise.
"Send it out."
Find all functions f:Z→Z such that for any number a,b,c satisfying a b c=0, there is
f(a)2 f(b)2 f(c)2=2f(a)f(b) 2f(b)f(c) 2f(c)f(a)
Chen Fan wrote the question and waited silently.
Qian Donghai looked at it and said,"Not bad. Everyone, do this question first."?”
Qian Donghai also took out a pen and began to calculate.
Time ticked by. Five minutes, ten minutes, fifteen minutes.
Someone had figured it out.
Then, the second person also calculated.
There were only two of them, a man and a woman from the affiliated university of science and technology.
The rest of the people who did not manage to calculate it in fifteen minutes were basically dead.
" If you don't have an idea after 15 minutes, you basically won't be able to do it," said Qian Donghai.”
F * ck.
Chen Fan's head began to hurt.
You so-called top students, why are you so weak? I came up with this question casually.
