Chapter 14: The shock of the math group

　　 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, then curiously leaned over.
　　 "Hiss—this question, Teacher Tang, did you ask a student to do this question?!"
　　 After seeing the Dao Cheng Nuo was studying, he couldn't help taking a breath.
　　 Cheng Nuo’s question is not small!
　　 Last year’s IMO (International Mathematical Olympiad) finals, the penultimate question was this.
　　 According to rumors, in the entire Chinese delegation at that time, only one of a dozen people solved the algorithm for this problem. And all the students who participated in the competition were solved by only five.
　　 One of the teachers in their math group didn’t know how to get this problem.
　　 Several teachers in their math group also tried it.
　　 But the result...it makes teachers like them uncomfortable! After two or three days of research, there was little practical progress.
　　 Now that he sees Old Tang actually come up with this question for a student to do it, his surprise is inevitable.
　　 You should know that those who represent China to participate in the IMO competition are the top high school students in China, and they are math geniuses selected from millions of students. And only one of these mathematics geniuses who represented the Chinese nation could solve this problem.
　　 One can imagine how difficult this question is!
　　 Did Teacher Tang think that this student in his class could be compared with the talented students participating in the competition?
　　 This male teacher wanted to stop Old Tang's seemingly absurd behavior.
　　 He just wanted to say something, but was stopped by Old Tang.
　　 "Shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh he shall be quiet, his time is almost critical, don't disturb him.
　　 Old Tang stared at Cheng Nuo's string of formulas 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. After listening to Old Tang's words, I realized that the kid 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 he was surprised, and his mind was as immersed as Old Tang.
　　 The teachers from the math group came in one by one, and when they saw a few people surrounded by Tang’s table, they joined in the fun.
　　Like the first teacher, they were surprised that Old Tang actually gave this question to a student to do. But after seeing that Cheng Nuona had written two full A4 papers, he was completely speechless.
　　 After a while, Cheng Nuo gathered four or five attentive math teachers.
　　 And Cheng Nuo, who was immersed in the process of verifying math problems, did not notice that there were people standing behind him. Cheng Nuo's concentration was extremely concentrated, and his brain was spinning like a machine that never stopped. Each number is calculated and combined in Cheng Nuo's mind.
　　 "Finally made it!"
　　 Ten minutes later, Cheng Nuo stopped writing, leaned back on the chair and stretched out.
　　 turned his head, and 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 standing behind me, do it now!" Cheng Nuo got up and scratched his head awkwardly.
　　 He is still wondering what so many teachers are behind him.
　　 "This classmate, what's your name?" There was a tremor in the voice of a forty-year-old teacher wearing glasses.
　　 "Teacher, my name is Cheng Nuo, I belong to 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 has not subsided.
　　 is too scary! It's really scary!
　　 It can be said that Cheng Nuo worked out this problem from scratch under his nose.
　　 As the saying goes, hearing is futility and seeing is believing. This is how he witnessed Cheng Nuo's enchanting behavior.
"How did you do it? I just did it, and I did it." Cheng Nuo continued with a calm face, "In fact, this question is not too difficult except to prove that the steps are a bit complicated. Most people do it. If it is proved within an hour, it shouldn’t be a problem! As for the teacher, ten minutes will be fine!"
　　噗! !
　　 Old Tang drinking tea was sprayed all over again by himself. However, looking at other teachers with constipation, he felt a little better.
　　 Cheng Nuo looked at the abnormal faces of the teachers, feeling a little puzzled.
　　 Did you say something wrong? Did you underestimate the math level of the teachers?
　　 He said that his speculation about this question was based entirely on his own feelings. In his opinion, although the difficulty of this question is there, as long as the idea is correct, the rest is just calculation. However, for Cheng Nuo, the huge amount of calculation is not a small job. This is why it took Cheng Nuo more than ten minutes to prove it.
　　 But now, it seems that the teachers' numeracy skills are not worse than their own. It's right 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 and they are definitely far behind them.
　　 "Haha. UU reading www.uukanshu.com. I mean, teacher, you are almost the same in about five minutes." Cheng Nuo forced an explanation.
　　 "..." All the teachers looked at Cheng Nuo with resentment.
　　 Old Tang waved his hand helplessly. This was his signature bombardment.
"Class is about to start, Cheng Nuo, you go back first, put your proof steps with me first, if you want, come to me to get it!" Old Tang looked at the other teachers teasingly, "You stay here again. Here, my colleagues probably disagree. Haha, well, you can go back first."
　　 "Oh, the teacher, I will leave first." Feeling the resentful eyes of those teachers, Cheng Nuo didn't know what was going on, but he should slip away. Say hello to Lao Tang, Cheng Nuo hurriedly left this place of right and wrong.
　　 Office of Mathematics Group.
　　As soon as Cheng Nuo left, the teacher took the process Nuo to write the problem-solving steps on the paper, looking word by word.
　　While looking at it, he was exclaimed, "It turns out that this formula is used here, and here is to prove this formula, genius, it is genius! You can think of other ways of doing this."
　　 It's not just him, other teachers are also stunned after reading Cheng Nuo's problem-solving steps.
　　 "Ms. Tang, this is Cheng Nuo from your class. It can be said to be an evildoer! But why have you never heard of him before?" a teacher asked suspiciously.
　　 Logically speaking, if their school has such a talented mathematics in any class, they would not know.
　　 "Old Tang, this is what is wrong with you, such a genius, you have been hiding and holding it, and it has ruined his future."
　　 "Yes, if he is allowed to participate in this year's Olympic Games, he might be able to bring back a championship for our school!"
