Looking at the topic on the blackboard, some of the students in the class couldn't help taking a breath.

"Hiss..."

"I can't see what this topic is. I'm a man with a high score of more than 80."

"If you say a hammer, I can't understand a man who gets more than 90 points every time. It's strange that you can understand it."

"This math problem is so terrible that I doubt the teacher can solve it."

……

All the students in the class are talking about it.

At this time, one of the students quietly took out his mobile phone and searched for the topic.

When he saw the content of the search, he suddenly widened his eyes and let out a exclamation.

"It's a world-class mathematical problem that takes a day and a night to figure out the answer."

"Most mathematical researchers can't even understand the process of solving problems. How can Chu Feng do it?"

This shocked voice soon spread throughout the class.

Class, immediately set off a burst of uproar.

"What, such a difficult math problem, no wonder I'm a man who scores more than 90 times and can't understand it."

"You say a hammer, this problem, don't say it's you, even teacher Zhang on the stage, I'm afraid there's no way?"

"Although there is a process of solving this problem on the Internet, you have to memorize it completely."

"Well, it's true that Chu Feng is a mathematical genius, but he certainly doesn't know how to solve this problem."

All the students in the class are not sure that Chu Feng can solve this mathematical problem.

At this time, Mr. Zhang scanned the class, and the classroom was quiet.

Immediately, Mr. Zhang looked at Chu Feng and said:

"as other students in the class said, even I can't solve this problem, but as long as you can solve it, what I just said will be effective."

"Of course, if you give up, we don't have to waste any more time, as long as you can listen to the class carefully and finish the task I told you on time."

To this, Chu Feng calmly smile, replied: "teacher Zhang, I want to try."

"Well, since you don't admit defeat, come up and have a try."

"But say in advance, your time is before class."

Zhang said faintly.

"No problem. I'm sure I can solve this problem before the end of this class." Chu Feng replied.

"Well, try it."

For Chu Feng's confidence, Mr. Zhang shook his head and said.

In her opinion, no matter how powerful Chu Feng is, it is impossible to solve the above problem.

You know, the above mathematical problems, but even the world-class mathematicians also spend a day and a night to solve them.

Even if Chu Feng has read the answer to the above question, he probably can't understand it?

Mr. Zhang thought so.

Under the gaze of the crowd, Chu Feng quickly stepped onto the platform.

Chu Feng glanced at the whole topic, and a smile came from the corner of his mouth.

In my heart, I said:

so it is. The difficulty of this question is really high.

However, this is not difficult for me.

Chu Feng shook his head with a smile.

Then he took out a piece of chalk from the chalk box on the platform and quickly wrote on the blackboard.

Chu Feng's chalk writing is very beautiful and neat.

It's like a printing press on it.

"Hiss!"

See this scene, some students in the classroom can't help but take a breath.

"This chalk is too neat, isn't it?"

"Well, I've been practicing calligraphy for several years. As a result, compared with the words written by Chu Feng, the words I wrote are just a lump of Xiang."

……

They couldn't help admiring Chu Feng's chalk.

However, some of them began to talk coolly.

"Cut, what's the use of good writing? It's a problem-solving, not better than who writes the words."

"That's right. No matter how good his handwriting is, if the title can't be solved, it's useless."

There was a lot of discussion in the classroom.

Some praise, some think that Chu Feng will lose.

Chu Feng didn't pay attention to the comments on the field, because at the moment he was concentrating on solving the problem, where he had time to pay attention to what they said.

On one side, Mr. Zhang watched Chu Feng solve the problem, but he shook his head secretly.

Because Chu Feng's problem-solving process, with the original version of the problem-solving process gap is too big, basically can not be the correct way to solve.

Chu Feng kept writing down the process on the blackboard.

Twenty minutes later, Chu Feng's problem-solving process has been filled with two blackboards.

Finally, Chu Feng wrote the answer."Teacher, I have solved the problem." Chu Feng put down his chalk and said to Mr. Zhang.

Suddenly, there was an uproar on the field.

"So quickly?"

"No, it's a problem that mathematicians spend a day and a night solving."

"I'll go. The answer seems to be right."

……

For a moment, the classroom became noisy.

"Be quiet."

Teacher Zhang calm face, yelled.

The sound of scolding, let all the students in the classroom, completely quiet down.

Seeing that everyone was quiet, Mr. Zhang looked at Chu Feng and shook his head: "although your answer seems right, the process of solving the problem is basically wrong."

"I guess you've read this question before, and you happen to write down the answer and write it on it."

After Mr. Zhang's words fell, everyone on the field showed a relieved expression.

"It turns out that's what happened. I'll tell you, how can a world-class mathematician solve a problem that takes one day and one night?"

"That's reasonable, just remember the answer."

"I said that no matter how God he was, he couldn't reach that level, could he?"

But under the gaze of everyone, Chu Feng looked at Mr. Zhang and slowly shook his head and said, "Mr. Zhang, my problem-solving process is not wrong."

"Your problem-solving process is too far away, how can it be right?" Mr. Zhang thought that Chu Feng was trying to be brave and said, shaking his head.

"Teacher, the process of solving mathematical problems is ever-changing. How can there be so-called standard answers?"

"This problem is calculated in this way. If you don't believe me, you can ask my friends who can see the process."

Chu Feng sighed and continued.

He doesn't admit defeat. He knows that this is the correct process of solving problems. That's what he said to Mr. Zhang.

"You don't think you did it wrong?" Mr. Zhang frowned and asked.

"That's right." Chu Feng nodded and answered truthfully.

"Well, teacher, some of my friends are famous mathematicians at home and abroad. I'll show them the problems you do and let them judge. What do you think?"

Mr. Zhang pondered for a while and said in a voice.

She put forward such a proposal, of course, not to believe that Chu Feng really did it right.

Just want to let Chu Feng die early, honest face reality.
