Everyone finally realized this problem, and suddenly they were struck by lightning, their faces were as black as carbon, and their heads were smoked...

Even the good-tempered Lin Leier couldn't help showing a faint murderous aura.

Not to mention other classmates, murderous, permeating the entire Chunfeng Middle School campus...

But Qiao Yingzi's eyes showed a very determined look.

In any case, when we deliver breakfast tomorrow, I must ask that guy Tao Cheng about it.

Jiang Xueying's cherry mouth closed and opened again, she realized what a stupid idea she just wanted to give way to Tao Cheng...

[Ding, negative emotions from Qiao Yingzi +20! 】

[Ding, the negative emotions from Lin Leier +10! 】

[Ding, negative emotions from Jiang Xueying +30! 】

【ding, from... 】

The negative emotions of the teachers and students in the whole school broke out in an all-round way, and they rushed to Tao Cheng like a mountain...

However, when it comes to negative emotions, it is Li Tiegun and Pan Shuai who are behind the two old pedants.

Because the two old pedants in front of them were listening deeply. They used to be ruddy with a smile on their faces, but now they were suffocated to black and red like a dead pig's liver...

It took a long time for Old Qin to spit out a sentence between his teeth:

"Tao Cheng from your school, good, very good, very good!"

Old Scholar Wu also gasped and murmured:

"If you don't send the last half of the sentence, hehe, top middle school, hehe..."

Li Tiebang and Pan Shuai were so frightened that their scalps became numb, and cold sweat ran down their backs.

……

[Ding, the negative emotions from the old pedant Qin +50! 】

[Ding, the negative emotions from Old Scholar Wu +50! 】

[Ding, negative emotions from Pan Shuai +80! 】

[Ding, negative emotions from Li Meng +100! 】

.. ......

Jingle bell~~

The bell for class rang, and Tao Cheng's footsteps also happened to step into the classroom of Class Three.

Facing the murderous gaze of the entire third class, Tao Cheng walked back to his seat calmly.

The remaining two classes are Li Tiegun's math class.

Therefore, even the students who couldn't wait to know what Tao Cheng's next sentence was, were all quietly waiting for Li Tiegun's arrival.

However, Li Tiebang did not appear for a long time.

In desperation, Qiao Yingzi, the representative of the class, had to go to inquire about the military situation.

At this time, Lin Leier was biting the pen, looking at the exercise book Tao Cheng arranged yesterday with a solemn expression, thinking hard.

"Haha, who asked you to hand in the answers to the exercises on your own yesterday, now you know you have a headache~". "

Fang Yifan stuck his head out and smiled happily.

Lin Leier stroked her eyes and replied calmly:

Well, the simple ones like the exercise book have been done a long time ago. "

"..."

Fang Yifan suddenly choked, and said angrily for a long time: "Who can't learn from Taoshen..."

[Ding, negative emotions from Fang Yifan +10! 】

Fang Yifan snatched the exercise book from Lin Leier's hand:

"Didn't you say it's already done, then what are you doing researching!"

Lin Leier pointed to a blank spot on the exercise book:

"Look, there are questions written by the teacher at random."

Fang Fan looked in the direction of Lin Leier's finger, and sure enough there was a line of writing, and it looked like Li Tie's handwriting.

He subconsciously read it out:

Prove that any even number greater than or equal to 6 can be written as the sum of two prime numbers.

what is this?

Fang-Fan looked confused. This question seemed simple, but in fact it was impossible to start.

He subconsciously took the question and turned his head to ask Tao Cheng who was behind him.

Tao Cheng glanced at it and recognized that this was the famous Goldbach conjecture.

In fact, the correct version should be (,) that any even number greater than or equal to 2 can be written as the sum of two prime numbers.

This is a question that students can understand, but it has stumped all mathematicians in the world.

Up to now, this is still one of the three major mathematical problems in modern times in the world, challenging the limit of wisdom of all mankind.

From 1742, Goldbach proposed this conjecture in a letter to Euler.

Countless algebraic mathematicians followed, and it wasn't until the early twentieth century that they began to find ideas.

陆续着,数学家们才开始证得”9+9”,”7+7””6+6”……等。

Until 1966, a great mathematician in China, Chen Jingrun, proved the "1+2" ​​theory in Goldbach's conjecture, which greatly advanced the proof of Goldbach's conjecture.

step.

And Chen Jingrun's "1+2" ​​is only one step away from "1+1".

As long as the "1+1" theory is proved, Goldbach's conjecture can be drawn to a perfect end.

This is the popular name for the so-called "1+1=2 conjecture".

In fact, the name is wrong, the correct one should be "1+1 conjecture".

However, over the past few decades, this "1+1", which is known as the jewel in the crown of mathematics, has no one been able to pick it off after all.

Even Tao Cheng's father, Tao Zhexuan, tried it, but failed.

Therefore, the question that Li Meng wrote on Lin Leier's exercise book is simply not something that a high school student can do.

However, this does not include Tao Cheng!

As an abnormal human with a brain developed to 15%, Tao Cheng naturally wanted to try it.

He took the exercise book from Fang Yifan's hand, and his serious expression made Fang Yifan's heart shudder.

Tao Cheng picked up the water-based pen and wrote directly on Lin Leier's exercise book...

Now Lin Leier and Fang Yifan do not know that this ordinary exercise book will become a treasure that major museums will collect in the future.

Tao Cheng wrote very carefully, mobilizing almost all the brain cells that can be used in the brain.

Moreover, without his subtle control flaws, his handwriting is also very beautiful.

Fang Yifan, who couldn't understand what Tao Cheng was writing, was shocked by Tao Cheng's handwriting that was more beautiful than a copybook.

Learning God is learning God, and in just a short period of time, he has practiced so beautifully.

But he didn't dare to speak out.

Because Tao Cheng had such a serious and dignified expression, it was the first time he had seen him, so how could he dare to disturb him.

"∥ Well, an old math professor will give you a lesson when he comes, so Mr. Li explained that before that, he should collect the workbook that was sent out yesterday. "

(Get it) Qiao Yingzi went to the office to ask, and then came back to announce to everyone.

"Ah? I just posted it yesterday, and I have to take it back today!"`

"Do you want to be so ruthless, I only did a few questions, woohoo~"

"Nima is all relying on Taoshen, what kind of exercise book do you have to send..."

"'"

The students were crying...

As clever as Lin Lei'er, she was also quite annoyed at this time, angrily:

Tao Shen is solving the world's problems!

I have to come to collect the exercise book at this time, isn't it sincere to make trouble?

Tao Cheng, who was writing at a critical moment, also stopped the pen in his hand.

He breathed a sigh of relief, even if he was as strong as him, he would have to spend almost all of his energy.

But this question doesn't need to be calculated any more.

Because of the calculation here, he has completely clarified the idea and proved it in his mind.

It's just a matter of writing or not.

Well, even if Mr. Li Meng came to him with half of the problems to solve...

It's not his fault for the tail docking or anything...
