My Identity As A Schoolmaster Has Been Exposed

Chapter 257 He Junfei’s Will (nine more)

After hearing his explanation, students from the other two provinces took a cold breath. They had never thought of this approach.

They began to whisper to the discussion: “It seems that after they save it, they must learn from it! They studied the Olympiad questions.”

The leading teachers from these two provinces also looked sideways at the moment, looking at Xu Cong, they were a little curious.

“If I remember correctly, there are 56 students who went to participate in the Olympiad. Why are 57 people present today?”

“Is this classmate in the third year of high school?”

They can only understand it this way, because the students here are all in the second year of high school, they all know it, and only the third year of high school can explain it.

But if Xu Cong is the trump card, why don’t you use it earlier in the game, and wait until the exchange meeting?

“I don’t think it’s very possible. Don’t mention the tasks of the third year. If the student is really good at grades, then he will naturally be recommended.”

“If it is a pass, there will be more free time. Why not participate in the Olympiad?

Several teachers were muttering here, and at the same time they glanced at Xu Cong from time to time.

“In other words, do you think that classmate is a bit familiar? I always feel where I have met him?”

“You mean, he participated in the Olympiad?”

“No, no, no! No, it’s somewhere else! But I can’t remember it for a while.”

This is a mathematics exchange meeting. The preconceived nature of these teachers is related to mathematics, so they didn’t think about other aspects at all. As for literature and other aspects, they were thrown out of the sky.

Several teachers stared at Xu Cong. When they looked at the blackboard again, they couldn’t help but twitch their eyes.

Because the proof idea written by He Junfei on the blackboard is half the length of the last classmate’s!

Intuitive!

concise!

It’s clear!

After He Junfei wrote all the practices, he said to everyone indifferently: “The above are the five situations!”

“To sum up, ×1, ×2, ×3, and x4 are all 1, or three of them are -1 and one is 3!”

After speaking, He Junfei didn’t give them a chance to think, so he started to erase the questions on the blackboard.

“!!!”

“What are you doing?! This classmate!”

Not only the host is anxious, but many of the classmates here are nervous.

They haven’t understood it yet, so it’s wiped out? Well what does that mean!

He Junfei turned a little, and said frankly: “Erase it! I also want to take out the title and share it with you!”

He said so on the surface, but in fact, this is Xu Cong’s request.

Xu Cong chose to tell him how to do this question, just to make this question disappear quickly.

His condition is: Go up and get it done quickly, and then erase my question. Putting this question on it is not pleasing to my eyes.

Therefore, after He Junfei performed himself perfectly, he did not humiliate his mission and erased his question.

So when everyone was stunned, he really erased the question, and then put his question on the blackboard.

topic:

Let a1, a2,… be an infinite term just a sequence, there always exists an integer N≠1, so that for each integer n≥N,

(a1/a2)+(a2/a3)++(a(n-1)/an)+(an/a1) are all integers. Prove that there is a positive integer M such that am=a(m+1) pair All integers m≥M are true.

After He Junfei finished writing, he said presumptuously: “Don’t always entangle the past! Learn from one another, and look to the future is the key!”

In a word, it refuted the dedication of the previous students to the Olympiad.

Afterwards, he continued: “Please enlighten me, classmates!”

“Just give ten minutes…”

“Hey! Ten minutes is a long time! After all, some students in our province don’t bother to read these questions!”

These words he said are very arduous, but who made this a communication meeting?

The better the performance, the more resources will be tilted!

You are secretly provoking, and we don’t pretend anymore!

We are backed by Xu Cong, what are we afraid of?

One person is enough to kill more than 100 people in your two provinces, so He Junfei is very confident now!

After writing the question, he walked down. Whether the host or the leadership of the Education Bureau, they were all impressed by him because they hadn’t seen such an arrogant classmate for a long time!

In the eyes of others, He Junfei is too pretended, too much, just a prickly head, but in the eyes of these people, they are very happy!

For example, there are thorns in every class, and they are often remembered by teachers for the longest time.

Look at He Junfei again, people have this capital arrogance.

After all, the answer written last time was indeed much better than that of the last classmate. This is obvious to all present!

For ten minutes, the students from the three provinces were all looking at the questions, which puzzled the teachers from the other two provinces.

“Isn’t this a topic prepared by their province? Why are they immersed in proof?”

“Even their leading teacher is blank, what’s the matter?”

“Could it be a temporary intention, a temporary problem?”

Brush!

The leading teachers from these two provinces stared at He Junfei.

But when they looked at He Junfei, he was also sullenly writing and drawing. At this moment, the only person holding his head up and looking at everything was Xu Cong.

“this….”

“what happened?”

Involuntarily, they also looked at the blackboard.

This question seemed very simple and familiar, but when the students really set out to prove it, the students knew the complexity and cumbersomeness of it.

“I can’t start! Hiss…”

“Fuck! Not at all!”

“Will Feng Hechuan meet?”

Many classmates turned their eyes to the gentleman student with glasses, his name is Feng Hechuan, the third place in the final of this Olympic Mathematics competition!

It is also the first in mathematics in the province!

He has won numerous awards since he was young, and he has been recommended to the Mathematics Department of Peking University!

At this time, he is earnestly proving that he has some eyebrows, but ten minutes is far from enough!

Even the teacher came forward and reminded him: “Ten minutes, it’s just their aggressive method, Feng Hechuan, don’t worry, slowly prove that you are sure, and then go up!”

“In addition, I also watched it. After that student finished the question, he immediately slumped his head while writing and drawing!”

“It’s very possible that they just have questions and don’t know the answers.”

Looking in the direction of He Junfei again, he saw that He Junfei handed the paper on which he wrote and painted to Xu Cong.

These teachers were suddenly stupid: “???”

What the hell?

Why did that classmate He pass his things to him?

And they also saw the shadow of the students asking them these teacher questions from this scene!

Very weird as time goes by.

He Junfei stood up again and said to the classmates who were still working hard, “Ten minutes are here!”

PS: Good night!

Remember to give five-star praise! ! ! ! !
