"There's something about this year's college math competition...... Who came up with this question? ”

Office of the Dean of the School of Mathematics.

Looking at the line of calculations written on the blackboard, Wang Shuangquan touched the stubble on his chin with his right hand, and a solemn look appeared in his eyes.

Standing next to him was Professor Li Xuesong of the Department of Mathematics, a leading figure in the direction of pure mathematics in China, and one of the chief examiners of the National College Student Mathematics Competition in early September.

"It seems to be Professor Liu Shoufeng of the Xia National Institute of Mathematics."

"It's actually this old thing...... a sudden expression appeared on Wang Shuangquan's face, nodded and said, "No wonder ......"

Mathematics is the foundation of science, and Xia Guo is founded on science and technology, and attaches great importance to mathematics, and holds national competitions such as the National College Student Mathematics Competition every year, mainly for college students majoring in mathematics, and the winners are expected to directly enter the national key research units.

Normally, in order to open up the score, the last big question is often the professor of the Xia Guo Institute of Mathematics.

It's just that no one expected that the last big question of this year, no one in the entire main examination committee made it.

Even among these people, including Professor Liu Shoufeng himself.

As a member of the main examination committee, Professor Li Xuesong still remembers how the old man played with him innocently when he found him-

"I didn't think this question would be so difficult, but I suddenly thought of it and thought it was interesting, so I wrote the test paper."

Now it seems that this question is quite beautiful.

If you don't know it, it will become a mathematical conjecture.

The old man Liu Shoufeng was happy and left it alone, but he suffered from the main test committee of their competition.

In this way, half a week has passed since the end of the exam, and the answer to this question is still a mystery......

Seeing that Dean Wang Shuangquan did not respond for a long time, Professor Li Xuesong asked tentatively.

"You...... What do you think of this question? ”

"I don't have a good idea yet, but my gut tells me that the answer shouldn't be difficult?" After thinking for a moment, Wang Shuangquan shook his head, "Let me think about it for two more days...... Speaking of which, what about the Yenching Institute of Mathematics? ”

Unlike the Xia Institute of Mathematics, which focuses on applied mathematics research, the Yenching Institute of Mathematics mainly studies pure mathematics.

Obviously, it is better to leave this kind of number theory problem to the experts.

"The question has just been sent to them, so I guess there is a seminar going on right now."

Dean Wang nodded and touched the stubble on his chin.

"That should be stable."

"Hey, I thought it was my ability to regress before, but I didn't expect that even your old man couldn't think of it, it seems that the problem is still in the question itself."

Looking at Professor Li Xuesong, who was smiling there, Dean Wang was a little embarrassed and coughed and said.

"I can't figure out what you want...... Didn't you just get it to me? ”

"Haha, I don't care, anyway, I'm balanced!" Li Xuesong smiled and waved his hand, "Don't talk about it, I'm going to class, there will be a section of advanced math in a while, and there are two classes of homework waiting for me." ”

"Homework? You shouldn't be assigning this question as homework? ”

"It's a thinking question, I didn't let them do it, how much they could do."

Looking at this unreasonable old thing, Wang Shuangquan smiled and said, "Aren't you bullying people." ”

If you can have this ability, you will have already taken the report card of the National Mathematics Competition and sent Yan University to Yan University. Although Jiangcheng University is also the top 10 in Xia and even the world, its resources are still a little worse than those in Yanjing.

"Bullying? Oh, I don't think it's pressed enough! These freshmen who have just arrived at the university are like ducks in the mountains, with no discipline at all! Today's students, their mental outlook is far worse than ours, and they are really not as good as the generation! ”

As he spoke, Li Xuesong shook his head.

Looking at his old friend, Dean Wang coughed dryly and said.

"A generation has a generation's way of living, and you don't keep using the old calendar to demand current students. You ask yourself, would you like your grandchildren to live in the old calendar, or in the new era? ”

"Can that be the same? How old is my grandson," after all, he couldn't say that he was the leader, Li Xuesong muttered, diverting the topic, "It's almost time, I'll go back first." ”

Dean Wang smiled and nodded.

"Go, go, go."

It just so happened that this question was quite interesting, and he also wanted to think quietly for a while.

If you can't figure it out, will you solve it?

Although it seems quite challenging......

……

Ding Ding Ding –

"Shhh...... Why hasn't Hao Yun come yet? ”

Looking at Lao Li, who had already stepped on the bell and walked into the classroom, Zheng Xueqian looked around a little anxiously, and whispered to Liang Ziyuan, who was sitting next to him, "This guy shouldn't have slept." ”

He didn't worry about Hao Yunque's lack of class, mainly because he helped occupy the position too high, and he threw the book there alone and was embarrassed. Especially this kind of small class with only two classes, it looks even more eye-catching.

Liang Ziyuan: "...... Possibly. ”

"Damn, don't come and say something."

Zheng Xueqian whispered, and before he was blinded, he took the book on the table away.

"In class, be quiet."

Li Xuesong, who knocked on the blackboard and walked onto the podium, threw the high math textbook in his hand on the podium, with his hands behind his back and an expression of a worldly master.

"The school committee of the class of 1801 took the homework."

As soon as I heard that the homework was being collected, there was a commotion of sighs and sighs in the classroom, and several students sitting in the front row looked at each other, but they only saw helpless expressions in each other's eyes.

"Did you write it?"

"I didn't write it."

"It's so difficult......"

"yes, yes, I can't write it at all!"

"I still have to hand in my homework, isn't that question a reflection question......

"It's over, it's over."

Seeing the students in the audience react like this, Li Xuesong didn't make any expression on his face, but he laughed twice in his heart.

Can't do it?

It's a coincidence that it can be made!

He Ping, who was sitting in the first row, bit his thumb and looked at the scratch paper on the table full of three or five pages, his brows were tightly knit and he didn't say a word.

Zhou Xuan, the little fat man sitting next to him, nervously poked his arm with a pen and asked in a low voice.

"What God, have you written it?"

"No ......"

"Damn, you can't even do it?"

The first province of the National High School Mathematics Competition!

Can't even do it?!

This guy doesn't play games in the dorm room, and spends his days in bed reading difficult books.

However, when he heard that He Ping hadn't written it, Zhou Xuan breathed a sigh of relief and was not as nervous as before.

What is the saying?

The law does not hold the public accountable!

If one or two people don't write it, that's the problem of those one or two people, and if everyone doesn't write it, then it's not everyone's problem, but the problem with the topic.

Not as optimistic as his roommate, He Ping didn't even bother to pay attention to him, and continued to stare at the question on the sketchbook and meditate, as if he had gotten into the tip of a bull's horn.

And no wonder......

After all, no matter how you look at it, this is a question that is so simple that it can't be simpler.

But the strange thing is that he has tried everything, but he can't do it!

Looking at the sad faces of the students in the audience, Li Xuesong couldn't be too happy in his heart.

He never thought that these future coders would be able to do this kind of problem.

Scold!

I want you grandsons not to take Lao Tzu's lessons seriously!

Now you know that you regret it, right?

However, happy is happy, and the majesty of the teacher still has to be put on display.

After squeezing out a trace of disappointment from his eyebrows, the old man who bowed his head comforted everyone with a pretending to be tolerant.

"It doesn't matter if you can't write it, you can write as much as you want, at least let me see your thoughts. The school committee of the first class, go and collect it, even if you just write a solution, you can collect it. ”

Hearing this, the students who handed in their homework below finally made a little movement, and hesitantly handed out the homework book in their hands that only copied one question.

There are also those who have not written their homework in the first place, and they are even more relieved, so they simply take the homework of the same table and copy the question, and then write a solution in the blank space.

Looking at the homework that had been collected in less than a while, Professor Li Xuesong smiled in his heart, but shook his head with a sigh on his lips.

"Seeing that one or two of you don't listen carefully, and some of you arrive late and leave early, I thought you all learned. I didn't expect such a simple question to be made by no one else. ”

"This class of students, I really don't know how you studied in high school!"

Hearing this, the students in the class were all ashamed.

To be honest, those who can sit in this classroom and take classes are strictly speaking, there is no real scumbag. Not to mention the overseas friends recruited by the international class, but at least in mathematics, physics and chemistry, none of them have a low score.

Therefore, this kind of soul torture is undoubtedly a bit damaging for them.

Especially for a student who had won a provincial grand prize and almost entered Shuimuyan University, it made him even more uncomfortable and wanted to bite off his thumb.

Why can't you write it???

It's impossible!

Seeing that Lao Li on the podium had already opened the cover of the high mathematics textbook, and he didn't plan to talk about this question that he couldn't figure out for half a week, He Ping knew that he couldn't wait any longer, so he got up from his chair suddenly.

"Teacher, I want to know the answer to that question!"

Zhou Xuan, who was sitting next to him, was startled by his roommate's movements and hurriedly stuffed his phone into a drawer.

Wang Ziyi and Yuan Gaofei were the same, looking at He Ping in a daze, not knowing what plane he was doing.

Coincidentally, Li Xuesong, who was standing on the podium, was the same.

Hearing this question, the expression on his face suddenly froze.

"Answer, answer? Hehe, I can't do such a simple question, so I'm embarrassed to ask me the answer, "In the end, ginger is still old and spicy, Li Xuesong was a little timid when he was caught off guard, but he quickly covered up the past with a serious face, and hit me back, "I'll give you the answer after a while, you think about it again." ”

As soon as he heard that he would have to wait a few days before announcing the answer, He Ping's face, which was originally not emotional, suddenly twisted a trace of pain for the first time.

"Teacher! Please! Tell me about it. ”

"Well, what will be said will be spoken, in two days...... Give you some time to think about it. Actually, this question is just for you to collect your heart, not the focus of our high math class, even if you don't know the answer-"

"I beg you! I haven't slept well in half a week......"

Looking at He Ping, who suddenly hugged his head in pain, Zhou Xuan, who was sitting next to him, was stupid.

it?

Is this learning crazy?

There was a commotion in the classroom.

Many people began to talk with a confused face.

"Who's that guy?"

"I heard that it's the first class of students who won the first provincial competition!"

"Holy! How did you read a software major? ”

"Who knows, no matter what people read, don't you think it's outrageous to throw us questions that can't even be done?"

"It turns out that people can really be driven crazy by mathematics......"

People are not only stupid in the 402 dormitory, but Li Xuesong who is standing on the podium is also stupid.

This guy ......

Isn't it stimulated?

I was also a little timid in my heart, this old guy who was thankful was also seeing this situation for the first time, and he hurriedly wanted to divert the topic.

"That classmate, I understand that you are very curious, but you sit down first, we are about to have class, and we will talk about any questions after class. By the way, I forgot to name them just now, so I'll call them first......"

He Ping's face was uncomfortable, but he still didn't want to sit down.

Obviously, this guy was stimulated, and now he didn't just get on the bar with himself, but the whole class was on the bar.

Just when Li Xuesong hurriedly opened the roll call, hurried footsteps suddenly came from outside the corridor.

Then the back door opened a crack, and a figure carrying a shoulder bag was seen lightly trying to sneak in from the outside.

Such an obvious big black mouse, of course Li Xuesong will not be invisible.

If he usually turns a blind eye, originally the university mainly relies on self-consciousness, which teacher can be a father and a mother like in high school?

But who wants to be so unfortunate today?

Hit the muzzle of the gun!

Li Xuesong, who was worried that he didn't have a chance to find a step down, suddenly turned his face into a board, took out a different momentum, and shouted as if he was cutting meat and chopping vegetables.

"The one who was late in the back."

"Stand for me!"

The voice was like a trull-horn.

Hao Yun, who had just taken two breaths and pulled out a chair and was about to sit down, almost didn't catch his breath, and the whole person was blindfolded......
