Omnipotent Data

Old Tang shook his head and smiled, pointing to the question in front of Cheng Nuo and said. Look at which question he is doing now?

The math teacher was suspicious for a moment, then came over curiously.

Hiss, this question, Mr. Tang, you actually asked a student to do this question?!

When the man saw what Cheng Nuo was studying, he couldn't help but gasped.

Cheng Nuo did this question for a lot of reasons!

Last year's IMO (International Mathematical Olympiad) finals, the penultimate question was this.

According to rumors, only one of the dozen or so members of the entire Huaguo delegation solved the algorithm for this problem. And all the students who participated in the competition were only five people who solved it.

This problem was obtained by one of the teachers in their math group in some unknown way.

Several teachers in their math group also tried to do it.

But the result... made them, the teachers, very uncomfortable! After two or three days of research, there is almost no progress of practical significance.

Now that he saw that Old Tang actually took out this problem for a student to do, it was inevitable that he would be surprised.

You must know that the representatives of Huaguo to participate in the IMO competition are all the best high school students in Huaguo, and they are mathematics geniuses selected from millions of students. And among these math geniuses representing Huaguo, only one of them solved this problem.

One can imagine how difficult this question is!

Does Teacher Tang think that this student in his class can be compared with the gifted students who participated in the competition?

The male teacher wanted to stop Old Tang's seemingly absurd behavior.

He was about to say something, but was stopped by Old Tang.

Shh~, keep your voice down, it's almost critical time, don't disturb him.

Old Tang's eyes were fixed on the series of formulas that Cheng Nuo had listed on the paper. The proof of the first question of this question has reached a critical moment.

The teacher standing behind Cheng Nuo always thought that Cheng Nuo was just writing and drawing on paper casually. After listening to what Old Tang said, he realized that it seemed that the boy in front of him was really proving this question!

He looked at Cheng Nuo's proof steps from the beginning, and the more he looked at it, the more surprised he became, and he was as immersed in it as Old Tang.

The teachers from the mathematics group came in one by one, and when they saw a few people around Lao Tang's table, they went over to have a look.

Like the first teacher, they were surprised at first that Old Tang gave this problem to a student to do. But after seeing that Cheng Nuona had already written the steps on two A4 papers, he was completely speechless.

After a while, four or five math teachers gathered behind Cheng Nuo.

Cheng Nuo, who was immersed in the process of proving the math problem, did not notice that there were already people standing behind him. Cheng Nuo's concentration was extremely concentrated, and his brain was running at high speed like a never-ending machine. The numbers were calculated and combined in Cheng Nuo's mind.

It's finally done!

Ten minutes later, Cheng Nuo stopped writing, leaned on the chair and stretched.

As soon as he turned his head, he stared at the four or five teachers behind him.

The atmosphere suddenly froze for two or three seconds. .

Haha, haha... Teacher, what are you all doing standing behind me? Do it quickly! Cheng Nuo got up and scratched his head in embarrassment.

He is also wondering now why there are so many teachers behind him.

This classmate, what...is your name? A teacher in his forties wearing glasses trembled in his voice.

Teacher, my name is Cheng Nuo, and I'm in Teacher Tang's class. Cheng Nuo answered honestly.

How did you solve this problem? The teacher pointed to Cheng Nuo's proof steps written on five A4 papers, and the shock in his heart still hasn't subsided.

It's scary! It's really scary!

It can be said that Cheng Nuo was right under his nose,

Calculate this problem from scratch.

As the saying goes, hearing is believing, seeing is believing, and this is how he witnessed Cheng Nuo's monstrous behavior.

How did you do it? I just did it this way, and I made it. Cheng Nuo continued with a calm face, Actually, this question is not too difficult except to prove that the steps are a little complicated. Most people do it If you can prove it within an hour, it shouldn't be a problem! As for you teachers, ten minutes will be enough!

puff--! !

Old Tang who was drinking tea was sprayed all over by himself again. But seeing other teachers also look constipated, he felt a little better.

Cheng Nuo looked at the unusual faces of the teachers and felt a little puzzled.

Could it be that I said something wrong? Did I underestimate the mathematics level of the teachers?

He said that his speculation about this question is based entirely on his own feelings. In his opinion, although this question is difficult, as long as the thinking is correct, the rest is just calculation. But even with that huge amount of calculations, it was a lot of work for Cheng Nuo. This is why it took Cheng Nuo more than ten minutes to prove it.

But now it seems that the calculation ability of the teachers is not bad compared to their own. It's right to think about it, after all, most of them are old teachers who have been working for more than ten years, and they are just students, so they are definitely far inferior to them.

Haha.. I mean, teacher, you'll be done in about five minutes. Cheng Nuo forcefully explained.

... All the teachers looked at Cheng Nuo with resentment.

Old Tang waved his hand helplessly, this is his signature sensational gesture.

Lesson is about to start, Cheng Nuo, you should go back first, and leave your proof steps with me first, and if you want them, come to me to get them! Old Tang looked at the other teachers teasingly, You stay here again Here, my colleagues may not agree. Haha, well, you go back first.

Oh, teacher, I'll be leaving first. Sensing the resentful eyes of those teachers, Cheng Nuo didn't know what was going on, but he should slip away. Greeting Old Tang, Cheng Nuo hurriedly left this place of right and wrong.

Mathematics Office.

As soon as Cheng Nuo left, the teacher took the steps of solving the problem written by Cheng Nuo on the paper and read it word by word.

While watching, I was still amazed, It turns out that this formula is used here, and this formula is proved here. Genius, simply genius! Such a different approach can be thought of.

Not only him, the other teachers were also stunned after reading Cheng Nuo's problem-solving steps.

Teacher Tang, this is Cheng Nuo from your class. You can almost call him a monster! But why have you never heard of him before? A teacher asked suspiciously.

Logically speaking, if there is such a monster in mathematics in any class of their school, they will not know.

Old Tang, this is your fault. You have been hiding such a genius, and you have ruined his future.

Yes, if he is allowed to participate in this year's Olympiad, maybe he can bring back a championship for our school!
