Old Tang shook his head and smiled, pointed 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, and then came over curiously.

"Hiss—, this question, Teacher Tang, you actually use this question for a student to do it?!"

After seeing the story Cheng Nuo was studying, the man couldn't help but take a breath.

The question Cheng Nuo did is quite good!

This is the penultimate question in last year's IMO (International Mathematics Olympics) final.

According to rumors, at that time, only one dozen people solved the algorithm of this question in the delegation of China. Only five students participated in the competition.

One of the teachers in their math group did not know how to get this question.

Several teachers in their math group also tried it.

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

Now that he saw that Old Tang actually took out this question and asked a student to do it, he was inevitably surprised.

You should know that those who represent China to participate in the IMO competition are the best among Chinese high school students, and are mathematical geniuses selected from millions of students. Only one of these mathematical geniuses who represent China to participate in the IMO competition have solved this problem.

It is conceivable how difficult this question is!

Does Teacher Tang think that this student in his class can be compared with the talented students participating in the competition?

The male teacher wanted to stop Lao Tang's seemingly ridiculous behavior.

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

"Shhh~, whisper, it's almost time to get to the point, don't bother him."

Old Tang stared at the strings of formulas listed on the paper by Cheng Nuo. 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 Lao Tang's words, he realized that it seemed that the boy in front of him was really proving this question!

He started Cheng Nuo's proof steps from scratch. The more he looked, the more he was more surprised, and his mind was also immersed in it like Lao Tang.

The teachers from the math group came in one by one. When they saw a few people surrounding Lao Tang’s table, they joined in the fun and went over to take a look.

Like the first teacher, they were surprised that Old Tang actually gave this question to a student to do. But after seeing Cheng Nuo's steps of writing two A4 papers, he was completely speechless.

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

Cheng Nuo, who was immersed in the process of verifying math problems, did not notice that there was a lot of people behind him. Cheng Nuo's attention was extremely focused, and his brain was running rapidly like a machine that never stopped. Numbers were calculated and combined in Cheng Nuo's mind.

"It's finally done!"

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

As soon as he turned his head, he stared at the four or five teachers behind him with big eyes and small eyes.

The atmosphere suddenly solidified for two or three seconds...

"Haha, haha... Teacher, what are you doing behind me? Hurry up!" Cheng Nuo stood up and scratched his head awkwardly.

He was also wondering now, there were so many teachers behind him.

"This classmate, what's your name?" A teacher in his forties wearing glasses had a hint of trembling in his voice.

"Teacher, my name is Cheng Nuo, I am from Teacher Tang's class." Cheng Nuo answered honestly.

"How did you solve this question?" The teacher pointed to Cheng Nuo's proof steps full of five A4 papers, and his shock had not subsided yet.

It's so scary! It's so scary!

It can be said that Cheng Nuo calculated this question from scratch under his nose.

As the saying goes, hearing is false and seeing is true. This is how he witnessed Cheng Nuo's evil behavior with his own eyes.

"How did it be done? I did it like this, and it was done." Cheng Nuo continued with a calm look on his face, "In fact, this question is not too difficult except for the complicated steps of proof. If ordinary people do it, it should not be a problem! As for the teacher, it can be done in ten minutes!"

puff--!!

Old Tang, who was drinking tea, was sprayed with him again. However, seeing that the other teachers were also constipated, he felt a little better.

Cheng Nuo looked at the teachers' unusual expressions and felt a little puzzled.

Could it be that I said the wrong thing? Did I underestimate the teachers' math level?

He said that his speculation about this question was entirely based on his own feelings. In his opinion, although the problem was difficult, as long as the idea was right, all that was left was calculation. However, the huge amount of calculation was a considerable job for Cheng Nuo. This was also the reason why Cheng Nuo took more than ten minutes to prove it.

But now it seems that the computing ability of teachers is not bad compared to themselves. It is correct to think about it. After all, most of them are old teachers who have been in the industry for more than ten years. They are just students, so they are definitely far inferior to them.

"Haha... I mean, teachers, you guys will be almost five minutes away." Cheng Nuo explained forcibly.

"……………” All the teachers looked at Cheng Nuo with resentment.

Old Tang waved his hand helplessly. This was his signature bombardment action.

"The class is about to begin. Cheng Nuo, you go back first. Put your proof steps here first. If you want it, come to my side!" Old Tang looked at the other teachers teasingly, "If you stay here, my colleagues may not agree. Haha, okay, you go back first."

"Oh, then teacher, I'll leave first." Feeling the resentful eyes of the teachers, Cheng Nuo didn't know what was going on, but he should have left. He said hello to Lao Tang, and Cheng Nuo quickly left this place of right and wrong.

Mathematics Group Office.

As soon as Cheng Nuo left, a teacher took the problem-solving steps written by Cheng Nuo on paper, looking word by paragraph.

While looking, he was also amazed, "It turns out that this formula is used here, and here is to prove this formula. Genius is simply a genius! You can even think of such a different approach."

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

"Teacher Tang, this is Cheng Nuo from your class. He can be said to be a monster! But why have you never heard of him before?" a teacher asked in confusion.

Logically speaking, no matter which class they have produced a talent in mathematics, they would not know.

"Old Tang, this is your fault. You have always kept hiding such a genius and ruined his future."

"Yes, if he was asked to participate in this year's Olympics, he might be able to win a championship for our school!"
