　　 The next day, Wednesday, in the classroom of Class Two of Sixth Middle School.

　　 Chen Yu leaned on the chair, staring at the teacher in charge, writing and drawing on the notes from time to time.

　　 "Buzz! Buzz!"

　　 Suddenly, there was a vibration from the mobile phone in my pocket, and I took out the mobile phone and found that it was a short message from a "overtime salesman".

　　【Overtime promotion: "Mr. Chen, congratulations! Your real fans have exceeded 30,000."】

　　 Chen Yu was taken aback, and then typed quickly and excitedly.

　　 [Chen Yu: "Did you just break through? Thirty thousand?"]

　　【Overtime promotion: "Yes, congratulations."】

　　 [Chen Yu: "It's only Wednesday today. Will it exceed 40,000 by next Monday?"]

[Overtime promotion: "The possibility is still very high. The homepage recommendation effect of the B station platform is great. It's a pity that all news, reposts, and discussions about you on the Internet are removed from the shelves, otherwise the increase in fans will be even higher." 】

　　 [Chen Yu: "I am blocked by the entire network?"]

[Overtime promotion: "Almost. Since reposts, news, posts and discussions of other platforms or media are not part of our company’s legitimate income, they cannot be blocked. But it’s okay. After the trial period is over, your live broadcast will be Videos can be published on multiple platforms, and any external force's ban on you will only get weaker and weaker."]

　　【Chen Yu: "Thank you so hard."】

　　【Overtime promotion: "It's not hard work, our interests are the same, these are what I should do."】

　　 [Chen Yu: "I really touched Yinhe Galaxy's dedicated staff, are you ready for the fourth phase of product application?"]

　　【Overtime promotion: "The process has already started, this is a very interesting product, you will love it."】

　　 [Chen Yu: "As long as I can break through 50,000 fans, I can bring that girlfriend back. (Withdrawn]

　　 [Chen Yu: "As long as I can break through 50,000 followers, I like it."]

　　【Overtime promotion: smile】

　　 Quit WeChat and took back the phone. Chen Yu sighed contentedly and tangledly, picked up his notes, and continued to listen to the teacher's lecture.

　　 Now, all the knowledge points he has missed have been made up, and there will be no feeling of incomprehension. And vaguely noticed that the teacher's teaching level seems to be very low...

　　 "Ring Ling Ling..."

　　 Twenty minutes later, the get out of class bell rang, the head teacher put away the preparation book, supported the podium with both hands, scanned the audience, and said: "Classmates, before get out of class ends, I want to notify one thing."

　　 "Hullah."

　　 A few male classmates who were just about to get up and rushed out, sat back in a chattering manner.

"Next Saturday, our Sixth Middle School will hold the Autumn Games. Whether it is an athlete or not, every student will come to fight for class honor and school honor! Cheers! Many leaders from education departments and even capital will come to this games. Everyone, everyone must maintain good discipline. It is the style of our Sixth Middle School!"

　　 After the words fell, the head teacher was silent for a moment: "What are you doing in a daze? Applause!"

　　 "Papa Papa Papa......"

　　 "Very good, get out of class is over!"

　　 The class teacher waved, and the students ran out of the classroom.

　　 "Chen Yu, don't go, come here."

　　 When Chen Yu was about to walk out of the classroom to get some air, the head teacher hooked his finger at him.

　　 "What's the matter, teacher?"

　　 "It's like this. Based on your monthly exam results, Principal Pang is willing to gamble to lose. At the same time, he decided that if you can get the first place in the school in the next monthly exam, you will never be forced to learn sports again."

　　 "Number one in the school?" Chen Yu was surprised: "Is this span a bit big?"

　　 "Anyway, the situation is such a situation, the matter is such a thing, if you have any questions, please talk to Principal Pang."

　　 After that, the head teacher picked up the prepared textbook, turned and left.

　　 "I must say it! Isn't it nonsense that the school is number one!" Chen Yu followed behind the head teacher and walked out of the classroom angrily, preparing to debate with Principal Pang.

　　 "Don't look for it now, the principal went to dinner with the leader, and went with the dean." The head teacher turned his head and glanced at Chen Yu.

　　 "Really?"

　　 "Why lie to you, you can go in the afternoon."

　　 At this moment, the teacher in the next math class of Class 2 came over and greeted Chen Yu and the head teacher: "Good morning."

　　 Seeing the math teacher, Chen Yu's eyes lit up, and he quickly stepped forward: "Teacher, are you not busy now? I still don't understand the finale of the last month's exam. Can you tell me something?"

　　 Hearing the words, the math teacher narrowed his eyes.

The head teacher beside 　　 also narrowed his eyes.

　　 The two looked at each other, nodding their heads insignificantly, and completed a "spy-level" information exchange...

　　 "Okay, no problem, you can't do any of the questions, the teacher will give you the answer now." The math teacher patted his chest grandly.

　　 "The final finale! I didn't understand the logic inside."

　　 Chen Yu took the math teacher to the podium, then ran to his seat and found the math test paper, then hurried back, put the test paper in front of the teacher, and pointed to the last math question: "That’s it, I don’t understand."

　　 "Oh." The math teacher frowned and nodded: "This question."

　　 "Right. How should I solve it? What is the idea?"

　　 "This question..." The math teacher reviewed the question carefully, spreading his hands: "Neither can I."

　　"?"

　　 "It's too difficult, none of the teachers in the school can."

　　 "Why don't you want to come out?!" Chen Yu roared.

　　 "We came out because we couldn't." The mathematics teacher scratched his head: "I want to see if there are other student associations, and then I find that the students won't either."

　　 Chen Yu: "……"

　　 "Chen Yu, don't look at me like that. No one is perfect, and Einstein has questions that can't, right? You can't force people to lock men."

　　 "Do you think you are reasonable?"

　　 "I don't know how to do it anyway." The mathematics teacher said with his arms akimbo: "Why can the problem be solved? Can't the three major conjectures in mathematics be solved?"

　　 Chen Yu: "……"

　　 "No."

　　 "... OK. OK. OK." Chen Yu took a deep breath, nodded, and pointed to the penultimate question: "What about this question? This question is also difficult, and I can't grasp the idea."

　　 "This question." The math teacher watched carefully for a while: "No."

　　 "Are you special..."

　　 "It's too difficult. It seems that our No. 1 student in Sixth Middle School got the answer right."

　　 "Students can answer correctly, can't you?"

　　 "Then some classmates still dance in the Pure Land of Bliss, why don't you?"

　　 "Can this be the same thing?!"

　　 "I don't know that question anyway."

　　 "Yes. It's awesome." Chen Yu turned a page of paper, UU reading www.uukanshu.com pointed to a blank question: "What about this?"

　　 "No."

"This one?"

　　 "Neither."

"This……"

　　 "Oh my god, I can't."

　　 "..." Chen Yu was silent, after a long while: "How much is 1+1?"

　　 When the math teacher's eyes lit up, he stretched out his hand and drew a piece of chalk, writing the formula crazy on the blackboard!

【One, 0 is a natural number; two, every certain natural number a has a certain successor x', and x'is also a natural number; third, if b and c are both successors of the natural number a, then b=c; 4. 0 is not a successor of any natural number; 5. Let S be a subset of the set of natural numbers, and (1) 0 belongs to S; (2) if n belongs to S, then n'also belongs to S. 】

　　 [……x is not in the range of f; f is an injective; if x∈A and “a∈A implies f(a)∈A”, then A=X……]

　　【……N (set of natural numbers) is not an empty set; there is a one-to-one mapping of a→a' from N to N……】

　　 [... If the subset P of N contains both non-successor elements and subsequent elements containing each element in the subset, then this subset is equal to N...]

　　【1+1 Proof:

The successor number of 　　∵1+1 is the successor number of the successor number of 1, which is 3,

The number of successors of 　　∴2 is 3.

　　 According to Peano's axiom ③, we can get: 1+1=……】

　　 In Chen Yu's shocked eyes, the math teacher took five minutes to write a blackboard formula, then he held his shoulders to meditate for another minute, and wrote the number after the =.

　　 [Available: 1+1=...13 thousand six hundred and twenty-seven. 】

　　 Chen Yu was dumbfounded.
