Today's main class is only Xu Shaowen's Chinese class, and he continues to teach his true meaning of answering questions.

In other subjects, as soon as class started, the teacher sent out the exam papers from last night's mixed-class exam.

The exam papers for the mixed-class exam were only one night after that and were all corrected.

Chen Zhou first received mathematics, and got 94 points.

Because the number of questions is reduced, mathematics is a paper with a full score of 100.

The same is true for comprehensive science, with only 200 points, 80 in physics, 70 in chemistry, and 50 in biology.

Looking at this bright 94, Chen Zhou thought, is this considered excellent?

After all, by score, it is more than 90% of the full score.

Of course, he just thought about it and knew it.

For an incomplete math test paper, the system cannot calculate that it can achieve small goals.

Chen Zhou turned the test paper to the end and looked at the finale of the function problem solved with advanced mathematical knowledge.

Wang Xuehui gave 14 points, full marks, no deduction.

Chen Zhou's mouth curled up a little, and he was a little proud.

Zhang Yifan noticed Chen Zhou's appearance, looked at him, and said in his heart, "Isn't it the last question that has been solved? As for it? This question is not difficult..."

However, when Zhang Yifan looked carefully at the answer written by Chen Zhou in the last question, a string of question marks appeared in his mind: "What's this? Lagrangian median theorem? Who is Lagrangian? How did he

Can you know these? That's right?"

On the podium, Wang Xuehui began to explain the topic, and Zhang Yifan had to temporarily suppress the doubts in his heart and listen to the lecture.

When get out of class was over, he immediately asked Chen Zhou and asked, "Chen Zhou, what are you writing about? What the theorem of Lagrangian? What is it? Can the question still be done like this?"

Chen Zhou was slightly stunned and looked at him.

Just as he was thinking about how to explain, Li Xiang heard Zhang Yifan's voice, turned around and asked, "Yifan, what were you talking about? What Lagrangian? Who used this theorem?"

Zhang Yifan pointed to Chen Zhou's test paper.

Li Xiang took Chen Zhou's paper and searched for it back and forth.

"The last question."

"Oh." When he turned to the last question, Li Xiang became more and more surprised as he read it.

After watching, he looked up at Chen Zhou, and his admiration in his eyes became stronger.

"Why are you looking at me like this?" Chen Zhou was covered in goosebumps when he was seen.

"Brother Chen, you are so awesome!" Li Xiang continued excitedly, "I only knew that you were good at Chinese and English before, but I didn't expect that Brother Chen, you are so good at math!"

Zhang Yifan was shocked by Li Xiang's exaggerated expression and tone, and couldn't help asking: "No, Li Xiang, what's wrong with Chen Zhou? What do you mean?"

At this time, Chen Haining also turned around and looked at him curiously.

Li Xiang picked up Chen Zhou's test paper, put it in front of Zhang Yifan, pointed to the "Lagrangian median theorem" written by Chen Zhou and the corresponding formula, and explained: "This theorem can only be learned after going to college and belongs to the advanced level.

Mathematics knowledge. Generally high school students don’t know anything, let alone use it to solve problems. Moreover, if you use advanced mathematics knowledge to solve high school mathematics problems, you must ensure that you are proficient in the relevant knowledge and cannot write any mistakes at all.

, otherwise there would be no 1 point."

"Damn it?" After hearing this, Zhang Yifan looked at Chen Zhou, then at Li Xiang, and asked, "Li Xiang, how do you know these?"

"I can do this theorem, but I dare not use it. I am not familiar with it and I am afraid of making mistakes..." After Li Xiang said that, he looked at Chen Zhou deeply, full of admiration.

Zhang Yifan and Chen Haining looked at each other, and Chen Haining asked again: "No, according to what you said, this is not something we can understand now. Where did you learn it?"

Li Xiang thought for a while and asked, "Do you know about IMO? Have you ever understood?"

Zhang Yifan and Chen Haining shook their heads.

Li Xiang asked again: "Do you know the National High School Mathematics Joint Competition and the Chinese Mathematics Olympics?"

The two nodded: "But what does this have to do with advanced mathematics?"

Chen Zhou also looked at Li Xiang with interest, waiting for his explanation.

After all, Chen Zhou didn't know what was involved.

Li Xiang continued: "The National High School Mathematics Joint Competition is a relatively high-level mathematics competition in the Chinese high school mathematics subject. You can understand that it has a higher status than the mathematics competition organized by our Anhui Province."

"Then, about 400 students who achieved excellent results in this national competition will be eligible to participate in the Chinese Mathematics Olympiad, which is what we often call CMO."

"And then, about 60 students with excellent grades in CMO can enter the national training team. After the training team selection, 6 top performers will enter the Chinese national team to participate in the International Mathematics Olympiad, that is,

IMO..."

Chen Haining couldn't help but interrupt, "It sounds very powerful, but what does this have to do with that theorem?"

"Don't be anxious." Li Xiang looked at him and continued, "Why should I talk about this IMO? Because the advanced mathematics knowledge that ordinary high school students cannot access is very common among IMO players.

For the sake of competition, I don’t know how many advanced mathematical theorems have been learned in advance. Like the Lagrangian median theorem used by Brother Chen, these players must master the knowledge."

"Anyway, except for the IMO players, I have never seen a few who can use these theorems in full. Even if others understand, they are not skilled. Like me, they are a half-baked person. So, do you understand?"

After saying that, Li Xiang looked at Chen Zhou with a scorching look.

Chen Haining and Zhang Yifan were a little slower, then said "Damn" and blurted out.

It turns out that this is a contestant participating in the international competition?

Chen Zhou looked at the eyes of several people. He didn't expect Li Xiang to say to this, IMO player... He looked high and looked high...

After thinking about it, Chen Zhou said, "Don't look at me like this. I really haven't participated in this IMO. These... I said I taught myself, do you believe it?"

Seeing the three of them skeptical eyes, Chen Zhou said again: "Uh... think about it, if I were an IMO player, would I still come here?"

This sentence reminded the three of them. When they were about to interrogate Chen Zhou again, the class bell rang.

The three of them had to give up temporarily and prepare for class.

Chen Zhou heard Chen Haining still whispering to Li Xiang again.

"Li Xiang, this IMO is so strong?"

Li Xiang: "If you don't understand, you will know when you go back to check the value of IMO in the evening."

Chen Haining asked again: "Then are you also an IMO player?"

"No, I am..." Li Xiang paused before saying, "Primary contestant..."

"Oh, that's fine. You are the same as me and Yifan." Chen Haining asked again, "Then do you think Brother Chen is really an IMO player? But he doesn't look like him..."

Li Xiang replied: "Is this important? Do you think it is important to be able to learn these theorems of advanced mathematics and apply them proficiently. Is he an IMO player?"

"And why I said that using this to determine the comprehension question, if you make a mistake, you will not have a single point. In fact, this is the protection of ordinary students in the college entrance examination, and not everyone can access this knowledge. For fairness, it has to be restricted.

You can't use it randomly. If you want to use it, you have to master it proficiently, otherwise you can do the questions honestly. You must know that mastering it proficiently and not making any mistakes at all is much more difficult than learning this theorem..." Li Xiang said this, and

He turned his head and looked at Chen Zhou.

Chen Haining was stunned, then suddenly realized, "That's right. It seems that Brother Chen has completely left us... I used to think that Brother Chen is only good at Chinese, but later I found that his English is also very good, but I didn't expect that he

Mathematics is even more outstanding than Chinese and English, and I went directly to advanced mathematics in college..."
