Teacher Xu, Please Take Care of the Reckless Students in Your Class

Xu Heng narrowed his eyes slightly, "You two, you are going too far!"

Meng Liangshan and Hong Yangjun smiled bitterly.

"Actually, this matter was not proposed by us!"

"That old Feng! Feng Hongqi! I love doing things the most! They think they can do other things during the time they come back!"

"He suggested that the nine people on the other side should start to study your manuscript on Teacher Xu, and on our side..."

"but……"

"Hey! It's really embarrassing! I really feel that I'm a little shameless, and I can't tell."

"Old Hong, come and tell me."

Hong Yangjun 22, "That's it! Teacher Xu, Lao Meng and I have been working on a problem of the law of numbers, and we haven't made any progress, so I would like to ask you to help us!"

Look at what it says!

How beautiful!

Please help me!

Pooh!

I don't know what kind of guts you have in your stomach?

Xu Heng rolled his eyes immediately, although he was a little disgusted, he was still willing to help.

Sitting down, he took out a pen and paper and looked at Hong Yangjun and Meng Liangshan, "Then talk about it! I'll help you early, we'll end early!"

Rumble!

Hong Yangjun was dumbfounded!

Meng Liangshan gasped again, and put his hand on the heart and pressed it well. He was afraid that he would be too surprised to see Xu Heng again, and fainted with excitement.

Xu Heng, "???"

"What's wrong with you? Isn't it just a number rule? Hurry up!"

Others don't know what this number rule is, but Meng Liangshan and Hong Yangjun are clear about it.

"hiss……"

They took a deep breath, then stepped forward.

Meng Liangshan suggested, "Let's go to the conference room! Principal Gu has already done everything!"

Hong Yangjun, "If you think the conference room is empty, we can go to the reception room, too!"

Meng Liangshan, "That's right! The reception room is fine! Let's not be in the office!"

The two had something to say.

Everyone heard that this number rule may take a long time, and it is really inappropriate to solve it so hastily in the office.

But Xu Heng still insisted on staying here as if he didn't understand.

He was so calm, and he thought so lightly that it would not take him much time.

The more he was like this, the more Meng Liangshan and Hong Yangjun became numb.

"Crash..."

Meng Liangshan took a deep breath, walked to Xu Heng and sat down, picked up a pen and paper, and wrote:

For any positive integer, if it is an odd number, multiply it by 3 and add 1; if it is an even number, divide it by 2; if it is an odd number, it will eventually return to 1.

"It can also be called a numbers game."

The crowd came together and took a closer look.

Yu Chuyao was startled, "Isn't this a hail conjecture?"

She looked at Meng Liangshan and Hong Yangjun suddenly, "You two! Are you testing Xu Heng? This is a mathematical conjecture!"

"Don't you think that if Xu Heng can prove the abc conjecture, he can solve the hail conjecture?"

Luo Xueting, "???"

"Hail... guess? Hail can also guess?"

Yu Chuyao glared at Luo Xueting, "Don't talk nonsense! This is a mathematical conjecture! It's the same as abc conjecture, brother's guess, and other conjectures! It's a mathematical problem!"

"In 1976, a math news recorded a story. In the mid-70s, on the campuses of many famous universities, people were like crazy, playing a math game day and night, night and day."

"The game is very simple: write any positive integer N, and transform it according to the following rules: if it is an odd number, the next step becomes 3N+1; if it is an even number, the next step becomes N/2."

"Not just students, but even teachers, researchers, professors and academics joined in."

Luo Xueting was surprised, "Ah? Really? This game is a hail conjecture? But I still think that this thing has nothing to do with hail..."

"Excuse me! I'm sorry I'm sorry."

Yu Chuyao, "This game is enduring!"

"Because people found that no matter what number N is, there is no way to escape back to bottom 1 in the end."
