The misunderstanding was eventually resolved

However, Professor Wu was very unhappy and kept hinting at Chen Fan....

After all, with Chen Fan, who can still look up to Pan Shuai!

What you can't get is always in turmoil, and those who are favored have no fear.

"What? Is he still your student? How do students become teachers? Isn't this nonsense? Professor Wu hadn't heard of it at all, so he became angry on the spot.

"No, no, all the formalities are in order, there is nothing wrong with being a teacher, and Chen Fan is a teacher, which is better than me to teach!" Li Meng told the truth.

“what？” Professor Wu was speechless.

Why didn't he believe it!

Li Meng is his beloved apprentice, and his level is there, otherwise he can't become a director at a young age.

"That's it, let Chen Fan give a lesson, you can just listen to it!" Li Meng had a flash of inspiration.

"Okay, I'll listen." Professor Wu said he didn't believe anything.

Chen Fan: "Teacher Li, no, Meng Meng, do you want to be lazy!?" I remember in the afternoon, there were three classes from you! ”

Li Meng said seriously: "This is a chance for you to prove yourself, do you know who my teacher is......"

Professor Wu was overjoyed by the praise, and his face was full of red light.

Chen Fan felt that there was no one for this old man!

I actually like to listen to sycophants!

Is it really a professor? Is it really a Taishan Beidou-level character?

Are you bullying me for being young?

Don't lie to me?!

Suspicious, he returned to the classroom

Li Meng led an old professor and sat in the back.

Li Meng sat down and said to Chen Fan, "Teacher Chen, please start your performance!" ”

Chen Fan looked at Li Meng who was enjoying himself, and affirmed in his heart that this product just wanted to be lazy and didn't want to go to class!

I grabbed him temporarily

Gu Senxiang looked at Chen Fan in surprise, and asked Huang Zhitao on the side, "Why is Chen Fan still lecturing in class?" ”

Huang Zhitao: "You are new here, you don't know, Chen Fan is Mr. Li's intern assistant teacher, and the class is also good." ”

Gu Senxiang looked at Chen Fan on the podium with strange eyes

This man is getting more and more mysterious!

"Well, today I'm going to talk about the workbook that was sent out that day! Huang Zhitao and Gu Senxiang read a copy first, and after a while, Gu Senxiang and Teacher Li went to her office to pick up a copy. Saying that, Chen Fan picked up the water cup that had been soaked in wolfberries.

He took a sip lightly, and then looked at the students below.

All students did not dare to have a trace of nonsense

They all took out their exercise books

Paper and pen

Chen Fan nodded with satisfaction and began the lecture.

Professor Wu watched and listened with interest.

After Chen Fan finished speaking a question, he was shocked!

He found that Chen Fan would talk about the knowledge points used in each question first

Tell the students who didn't do it right, their own shortcomings, and the questions they didn't get right because they didn't master that knowledge point!

The effect of this can be imagined

Professor Wu is not only a scientific researcher, but also a teacher who has been practicing for decades.

What kind of teaching level Chen Fan has, he understands almost everything after listening to a question.

And he found out that the classmates in the class were actually memorizing the knowledge points that Chen Fan said.

But after thinking about it, it is also a matter of memorizing the knowledge points, and even the students who do it right have benefited a lot!

When everyone does the question, they don't have a clear idea, maybe they just feel.

Sometimes, you can't tell the knowledge points at all.

"Xiaomeng, this teaching method is the most useful, teaching the method of doing questions is not the goal, the purpose is to teach how to use knowledge points reasonably!" Professor Wu couldn't help but admire.

"Well, the teacher is already improving the teaching method, and the teaching and application of knowledge points have been put on the agenda!" Li Meng also said solemnly.

The class continues

It's time to ask questions

When everyone's questions are answered

Lin Lei'er silently raised her hand: "Teacher Chen, I can't understand a question in this workbook, can you show me?" Next to the page number on page six. ”

Chen Fan opened the workbook: "Any even number greater than or equal to six can be written as the sum of two prime numbers!" ”

glanced at Lin Lei'er

"Poof-" Li Meng took a workbook from the classmate next to him, and when he came over to look at it, he couldn't help but smile.

Professor Wu also took it: "Hahahaha." ”

The two smiled wryly, and then looked at Chen Fan.

They know that this is the world's most famous Goldbach conjecture.

This question should be placed next to the page number, and it should be used as a decoration for the workbook, just like other workbooks with famous quotes next to the page number.

It's just that Lin Leier loves to study a little, and she doesn't even let go of the page number question.

However, neither Li Meng nor Professor Wu planned to relieve Chen Fan.

They wanted to see Chen Fan deflated

As for the solution?

They didn't think about it

Because since the Goldbach conjecture was proposed in 1972, it has become one of the three major problems in the world, challenging the IQ of all mathematicians!

"The original problem of this problem is that any even number greater than or equal to two can be written as the sum of two prime numbers!" Chen Fan said loudly.

"Since 1742, countless mathematicians have followed one after another, and this problem is the Goldbach conjecture!"

"In 1966, a great mathematician in China, Chen Jingrun, proved the famous 1+2 theory, which is still one 1+1 theory away from Goldbach's conjecture!"

Lin Leier realized her mistake at this time and hurriedly stood up: "Teacher Chen, I'm sorry!" ”

Chen Fan shook his head: "Actually, this theory is not so difficult!" ”

“！！！”

Professor Wu has even stood up!

"Do you know what you're talking about?"

"Hahaha, of course I do!" Chen Fan asked himself about the three major problems in the world, and it was difficult for him to have developed thirty percent of his brain.

"I'm a teacher at this point! I'll take responsibility for what I say, but I have a request if I prove it today.... Can I graduate early, after all, I am a teacher and a student at the same time! Chen Fan smiled.

"If you prove it, let alone China, I dare to guarantee that the world's famous schools are at your disposal! Even if you don't take any exams! Professor Wu said loudly.

Some of Li Meng's introductions just now have reminded Professor Wu of who Chen Fan is!

Erdsh Difference Problem!

The same high school student who solved the Erdsh discrepancy problem a few years ago.
