Chapter 322 A 300-Year Unsolved Mathematical Conjecture
This question is very similar to the sample question in the notebook given to him by the old man Wang Yongfei, and Yang Yihang was amazed by the ingenious way of solving the question.

Because, Wang Yongfei only took three steps to solve the whole question!It is really amazing.

However, this question is placed at the end of the notebook. Yang Yihang hasn't looked at it carefully yet, and how to solve it will have to wait for later study.

It seems that Yang Yihang gave Cui Renjie a condition to make the whole question easier, but added more restrictions.

Hey, there is a reason why Wang Yongfei can be reused by the country.

This Cui Renjie wanted to torment him as soon as he came in, so don't blame him... Huh!Who is afraid of whom?

The students in the audience were a little curious.

"This is one more condition."

"Everyone has studied mathematics, so you should know it. In mathematics, the shorter the question, the more complicated it is, because there are fewer conditions. But Yang Yihang added a few more conditions, which should be more complex than the previous question. It’s much simpler, right?” A boy who was the new squad leader sat down and forced to explain.

The monitor explained this, and the students around nodded together.

The squad leader is right!

Master Yang Yihang added a few conditions, and this question will be easier.

Everyone looked at Cui Renjie expectantly.

Students who pay attention to mathematics should know the name of Cui Tiancai.That is the existence of contemporary Hua Luogeng.

The headmaster really paid a lot of money to invite Cui Renjie to come here?
Presumably, Mr. Cui can solve this problem given by Master Yang Yihang without any effort, right?

Everyone likes to watch the excitement, and everyone looks at Cui Renjie eagerly.

A drop of sweat fell from Cui Renjie's forehead.

Yang Yihang smiled and stuffed the chalk into Cui Renjie's hand: "Mr. Cui, this is the advanced mathematics level of the junior year. Come on, come on, teach me. After all, I couldn't even answer the question just now."

Yang Yihang is not afraid at all.

Because he is a student.

He can show weakness!

He is a hungry sophomore!

But Cui Renjie in front of him is a teacher. The teacher who is going to teach them doesn't have any real materials. Will the students in the audience agree?

It's not strange if you don't go crazy.

Yang Yihang stood aside with a smile, while Cui Renjie looked at the topic in front of him with a chalk.

Yang Yihang added a condition, which was too tricky and restricted many ideas for solving problems in an instant.

Cui Renjie gave Yang Yihang a hard look with his long, narrow mouse-like eyes.

Yang Yihang definitely did it on purpose.

How could this girl be so kind?

Yang Yihang nodded, yes, I did it on purpose.Can you fix me, can't I fix you?

"Teacher Cui, what's wrong with you? Write the answer!"

"This should be easy for Teacher Cui, right? Didn't Master Yang Yihang say that this is the level of advanced mathematics for college students?"

The students in the audience couldn't help being a little puzzled when they saw Cui Renjie holding the chalk but not doing it for a long time.

Isn't it a genius?
The question becomes easier, but you can't answer it?

Yang Yihang curled his lips into a smile.This kid, if he doesn't teach him a lesson, he will really be turned upside down!
Sweat gradually appeared on Cui Renjie's forehead, this question is a bit difficult...

It is a bit difficult for him to answer in a few minutes.

Give him half an hour and he should be fine.

How could Yang Yihang make Cui Renjie happy?
He said from the side: "Mr. Cui, didn't you just say that the question you gave me can be solved in a few minutes? Then it must take less than one minute to answer this question, right?"

A mouthful of old blood was stuck in Cui Renjie's throat, and he almost spurted it out!
Yang Yihang specifically tricked him?
Yang Yihang suddenly glanced at his roommates and winked at them.

I have been roommates for a year, and I have a good sense of understanding.

As soon as they saw the eyes of the third child, Sun Quan immediately shouted: "What kind of teacher is this, he can't even do high math problems in college!"

Xiao Liqun followed suit without giving anyone time to talk: "That's right, he can teach us at this level? Mathematics is difficult in the first place, and our level is not high. He won't lead us into a ditch, right? "

"Fortunately, our third child has specially added new conditions. This topic is much simpler. Even if he doesn't know it, I really doubt that he can teach us advanced mathematics?" Ding Zhiming said casually.

Cui Renjie tightly held the chalk in his hand, with a look of embarrassment on his face.

He was a little angry, he really wanted to yell at this group of idiot students: This is not a college student-level topic!Even master students may not be able to do it!

But...the words can't be said.Once you say it, you will definitely be scolded to death.

Deliberately presenting difficulties to Yang Yihang.

Cui Renjie was suffering for a while and couldn't tell, his face turned red and white for a while...

Cui Renjie thought for a while: "Give me half an hour and I should be able to figure it out..."

Yang Yihang shrugged: "Teacher, this is the classroom, the place where you teach, we all paid the tuition... Time is so precious now, we can't delay the precious time of all the students who are about to build Huaxia because of you what!"

Cui Renjie was so angry that he wanted to vomit blood, he said with a sullen face, "Then Yang Yihang, what would you say is the answer?"

Yang Yihang glanced at Sun Quan who was flipping through his notebook, and immediately said: "Don't talk about me, the fat people in our dormitory can do it!"

Sun Quan's heart sank, he always felt that something was wrong...

Sure enough, Yang Yihang immediately called out: "Sun Quan, tell me, what is the answer to this question?"

Sun Quan stood up, looked at Yang Yihang, and then at Yang Yihang's notebook, and said, "...2! The number 2!"

Yang Yihang nodded: "Look, I've said it before, Sun Quan, who is at the bottom of the high math score crane in our class, knows that the answer is - 2!"

When the students around heard it, they immediately said: "This fat man is the one at the end of the crane, everyone knows it."

"That's right, is this person just a waste of his name? Sun Quan can do it, and he still needs half an hour as a teacher? Are you kidding me?"

The students looked at the ugly Cui Renjie suspiciously.

Suddenly some students shouted: "I heard that there are two brothers in their family. Could it be that the real genius is the elder brother?"

Yang Yihang shrugged, walked down with a smile, and said to the classmate: "You mean his brother? He did something bad and sent him to prison. Teacher Cui Renjie is a veritable genius!"

This time the students were even more skeptical.Is this a fake?
I really want to kill Yang Yihang!
Cui Renjie was standing on the podium, he really couldn't get up and down, he was about to suffer internal injuries!

He immediately started the class, and no one wanted to listen to the class under the podium.

You can't even do college-level questions, so you expect him to teach others?

Just kidding, isn't it?

Cui Renjie experienced the first lesson in his life, which he will never forget in his life...

This matter was directly reported to the principal...

In fact, the principal is still very concerned about Yang Yihang.

Yang Yihang's high math teacher was naturally concerned about the first class.

"What? Teacher Cui can't even solve high math problems for college students?" The principal was shocked!
This is impossible.Didn't that mean that Cui Renjie was a genius?
How many institutes think about the desired characters?

I have also helped many people decipher passwords and won rewards.

The principal was thinking that after Cui Renjie became a teacher for a month or two, let him evaluate his title and become an associate professor.

As a result, this kind of thing happened on the first day?
The director of the learning department nodded: "Yes, principal, I followed your instructions. That's true. Teacher Cui Renjie was very embarrassed. And..."

The headmaster frowned: "And what?"

The director said embarrassingly: "Besides, many students didn't want to listen to that class that day... They said that a teacher of this level is too bad, it's better to let Master Yang Yihang take it..."

The headmaster slapped his forehead, a little angry.

Was he deceived by Cui Renjie?
"Let's wait for one more month. If it's still too bad, forget it, just fire me!" The headmaster dropped this sentence and left.

Cui Renjie quickly got a reply to the principal's words, and his face turned black with anger.

If it wasn't for dealing with Yang Yihang, would he have gone to Jiangzhou University to do such a thankless thing?
Cui Renjie watched the group of students spread rumors about him on the Jiangzhou University forum, and threw the phone out of his hand in anger!

Fuck your sister!

These idiot students with no level of knowledge!

But Yang Yihang went directly to Wang Yongfei with Cui Renjie's question, and Wang Yongfei was still asleep in the library.

After Wang Yongfei woke up, he showed Yang Yihang the problem, and he was a little surprised: "This problem is not a professional mathematics doctor, so it should be impossible to solve it? Xiao Yang, where did you get it?"

When Yang Yihang heard this, he sneered in his heart. Cui Renjie really wanted to trick himself...

Yang Yihang asked: "Then master, how do you calculate this question? What is the answer?"

Wang Yongfei rolled his eyes and smiled: "I can tell you the answer, number 2."

Yang Yihang was a little surprised, this was the same answer to his previous question.

Yang Yihang couldn't help asking, "How did you do it?"

Wang Yongfei shook his shoulders: "Want to know? Then you cook me a dish for the master? I want to eat spicy chicken recently."

Yang Yihang turned around and left: "No need, I'll go back and think for myself."

After walking a few steps, Wang Yongfei rushed up and grabbed Yang Yihang's sleeve, "Forget it, I'll give you the idea of ​​solving the problem, otherwise you won't be able to figure it out at your current level."

Wang Yongfei took the paper and quickly wrote down the ideas for solving the problem.

Yang Yihang took a look, and suddenly had some eyebrows.

This old man Wang is really very skilled.

Holding the piece of paper, Yang Yihang asked suddenly: "Then master, you stay in the library every day? Do you have no other pursuits?"

Don't you like this kind of professor the most?

Why are you willing to go to a university as a librarian?
Professor Wang chuckled: "I'm thinking about two things right now. I eat your cooking every day, and the other is... to prove a conjecture."

guess?

What do you mean?
Wang Yongfei continued: "Do you know what 1+1 equals?"

"2."

Wang Yongfei nodded, "Then do you know Goldbach's conjecture? I just want to prove this conjecture in my lifetime, or...have a chance to see this conjecture proven!"

People who have been engaged in this kind of research all their lives naturally want to see the conjecture proved.

This conjecture has been around for almost 300 years, and no one has been able to prove it so far...

If this is proved, it will be famous in history.

Wang Yongfei also hopes that he can live to that day.

Wang Yongfei looked at Yang Yihang's dazed look, and smiled: "It's nothing, it's fine if you don't know, anyway, it's good if you can understand the conjecture at your current level."

Yang Yihang felt like shit in his heart, this Wang Yongfei really looked down on him!

Yang Yihang took the solution to the problem and turned around and left.

Wang Yongfei shouted from behind: "Xiao Yang, why are you leaving? Didn't you promise to cook for me? Hey, Xiao Yang!"

Yang Yihang has disappeared...

Yang Yihang walked to the dormitory with the idea of ​​solving the problem, watching while walking.

Suddenly, a cold voice stopped him. "Yang Yihang."

Yang Yihang's expression changed slightly, and he suddenly raised his head.He had a half-smile: "Hey, isn't this our Teacher Cui? Have you seen that forum? There is also your photo!"

The students put Cui Renjie's photo on it...

A mathematics professor saw it by the way, and felt a little angry.

What kind of teacher is this?
Such a bully?
How could Cui Ren's outstanding question be the advanced mathematics level of college students?College students are not so awesome!
Even if you call a doctoral student majoring in mathematics casually, you may not be able to calculate it within half an hour!What a bully!

The math teacher only saw Cui Renjie's outstanding questions, but didn't see the questions Yang Yihang added later...

The math teacher is straightforward, and he always hoped that Yang Yihang would switch to them to study their mathematics major, so he was quite concerned about Yang Yihang's affairs.So the mathematics professor turned around and went to the principal and told him about it.

The headmaster's face... is a bit complicated...

The director of the study department always felt that Cui Renjie's life would not be easy in the future.

Cui Renjie looked at Yang Yihang in front of him, and Cui Renjie glanced at the paper in Yang Yihang's hand.

It happened that I saw that it was the problem-solving idea of ​​the problem he asked before.

Cui Renjie raised the corners of his lips, and said contemptuously: "It seems that student Yang Yihang still doesn't know how to do this question..."

Yang Yihang smirked: "Didn't Teacher Cui also solve the college-level questions I gave?"

Cui Renjie's little oh made that momentary stiff.

This guy really can't open any pot!Just to piss him off.

Seeing Cui Renjie's expression changed, Yang Yihang lowered his voice and said, "Cui Renjie, kill someone, don't try to escape so easily."

Sooner or later, the police will come to the door and throw him in prison, where he and his brother will go to jail together, as a pair of brothers and sisters!
Cui Renjie's face changed slightly, but he smiled evilly: "I... look forward to that day."

So fucking confident!

I guess they thought they had no proof?
You wait!

Yang Yihang sneered.

This kind of person walks too much at night, and one day he will run into a ghost!
Yang Yihang thought to himself, this Cui Renjie definitely didn't just want to be a teacher when he came to Jiangzhou University.

Either against him... or his girlfriend, friend...

Paralysis, bad luck!
