After cleaning up Zhao Dezhu and them, Zuo Yan returned to the classroom to prepare for the next math class.

After the bell rang, Zuo Yan saw his math teacher, a bald man about forty years old.

According to the information in Zuo Yan's memory, his math teacher's name is Zhao Qiang, and his class is good. But he didn't deal with the previous Zuo Yan, because his class was messed up by the previous Zuo Yan.

So after Zuo Yan's family had an accident, Zuo Yan's life was naturally not easy.

And his math is not good in the first place, losing face in three days is a trivial matter, and he is often called by this guy to stand in the corridor with his schoolbag.

I hate this guy to death in Zuo Yan's memory, because he is always provoked by him and looking for opportunities to hit him.

Although he is now controlling Zuo Yan's body, it cannot be ruled out that he will be targeted, but it is nothing to target, and now he is not Zuo Yan before.

"Class!"

"Hello teacher!"

"Hello students, please be seated!"

After another routine, Zhao Qiang also checked the completion of the test paper first, as always, because the mathematics course that should be taught has been almost finished, and the current mathematics class is constantly brushing questions.

When he checked Zuo Yan's place, he was also frightened by Zuo Yan just like Xia Shiyun in the previous class.

Zhao Qiang obviously didn't believe it, and asked Zuo Yan, "You did it yourself?"

Zuo Yan nodded: "Well, do you have any opinions?"

"No, it's just that you're doing so well, and I'm just a little surprised by your previous performance. ”

As he spoke, Zhao Qiang didn't care about Zuo Yan, and after checking and getting on the podium, he began to speak.

Seeing him like this, Zuo Yan thought that he didn't plan to trouble himself, so he took out his history textbook and began to read it. No, it can't be said to be watching, it should be said to be "flipping!"

A class came to an end with the relish of Zhao Qiang's lecture and the attentive listening of the students.

When he began to talk about a question that everyone got a lot wrong, he stopped and said to Zuo Yan, who was reading a history textbook below: "Zuo Yan, come to the blackboard and tell everyone about your thinking about doing this question." ”

Zuo Yan, who was reading a book, put down the textbook in his hand, thinking that he really had to trouble me, and walked up slowly.

There is already someone below who is opening, betting on how long he can hold out on the podium, and the bet is on today's lunch.

After Zuo Yan came to the stage, he just looked at it for a while, and no less than three solutions to this problem came to mind. He chose the solution with the fewest words, picked up the chalk from the lectern, and began to write freely.

The two people under the podium saw that Zuo Yan had actually started writing, and they were directly blindsided.

The man exclaimed: ", what's the situation, this fat pig actually let it be written?"

"What are you afraid of, it's just nonsense, who wouldn't!"

The girl on the side replied, but she didn't know the bottom of her psychology.

About a minute later, Zuo Yan finished writing, put down the chalk and returned to his seat.

Zhao Qiang had been reading the style written by Zuo Yan just now, because he didn't believe that Zuo Yan could write it.

At first, like those two, he thought that Zuo Yan was writing blindly, because he couldn't understand what Zuo Yan was writing because a math teacher couldn't understand what Zuo Yan was writing.

When he finished writing it all, Zhao Qiang found out that he was using an inverted operation, that is, the reverse deduction method.

Only two very simple derivative formulas were used, and the correct answer was found, and the more he looked at it, the more he felt that Zuo Yan's two formulas were used well.

Even he didn't find out that there was such a practice, so he watched it for a while, wanting to learn Zuo Yan's way of solving the problem.

As a result, Zhao Qiang's non-speech, in the eyes of the two people who bet, it became impossible to say anything that made Zuo Yan write blindly.

The boy said happily to the girl next to him: "Let's go, I can't eat at noon, you count me as losing!", which made the girl look loveless.

There are still many people who think the same as the two of them, and it may be said that no one in the class believes that Zuo Yan can write it at all, but then Zhao Qiang's words slapped him in the face.

"Well... Good... Good!"

"Zuo Yan's writing is so good, I didn't expect this kind of problem solving idea, you all have to learn it, use the simplest formula to find the answer, sometimes it is the best solution. ”

Zhao Qiang walked to the podium and praised Zuo Yan, and then he explained Zuo Yan's solution to the problem for the students below who looked confused.

Then they were stunned, and many people looked back at the fat man in the last row. There was nothing but surprise and confusion on their faces.

Zuo Yan's Di Nishang was embarrassed, but Zuo Yan didn't react at all, still looking at his history textbook.

And Zhao Qiang on the podium couldn't speak energetically, so he used Zuo Yan's thinking to substitute for the next question, but he couldn't go on halfway through the lecture.

He scratched his head, and suddenly thought of Zuo Yan in the back row, so he said to Zuo Yan: "Zuo Yan, can you tell us about the solution and ideas of this problem?"

Zuo Yan, who was flipping through the book vigorously, heard Zhao Qiang ask himself to do the question again. Extremely impatiently, he stood up and walked over, and said to Zhao Qiang, who was smiling:

"The last time, if there is anything else to bring together, I will do it for you at one time, and you will leave me alone in math class in the future!"

When Zhao Qiang heard this, a trace of displeasure appeared on his face, "Why did you float up after praising you?"

He didn't speak, he just made up his mind that he would have to let Zuo Yan suffer for a while, otherwise this kid would have to go to heaven.

"Yes, you can write this question first!"

Zuo Yan took the test paper, looked at it for a while, and then turned around and wrote on the blackboard.

This time, it took Zuo Yan about five minutes to finish writing the question.

By the time he finished writing, the classroom fell into a deathly silence.....

", is this all the solution that this girl wrote?"

"One, two, three, four, five! Five solutions, my God!"

Tang Yu saw the dense piece written by Zuo Yan, and asked the people around him. Because of the above solution, he couldn't understand it.

His tablemate was a good-looking young lady, and when Tang Yu asked her, she replied: "I can only see the second one, and the second solution is right!"

At this time, her best friend in front of her turned around and interjected: "I understand the third solution and the fifth bell, is what he wrote right?"

Hearing this, Tang Yu and several people at the table were shocked, and a thought came to their minds: "This fat man is going against the sky?"

"Write a solution in a minute, he can't remember so much even if he memorizes it, and the answer is only one solution, so how did he find the rest of the solutions. ”

Zhang Yang, the representative of the mathematics class, muttered indifferently, but it is estimated that no one knows the answer to his question except Zuo Yan himself.

Zhao Qiang, who was on the podium, saw that Zuo Yan wrote five solutions in one breath, and there was another solution that he couldn't understand, so the whole person fell into a stupor.

After a while, he exclaimed, "How is this possible!"

Why exclaim? Because he finally came up with the first solution.

He thought it was incredible, so he couldn't help but scream.

Five solutions, he, a math teacher, couldn't think of it, Zhao Qiang looked at Zuo Yan on the side, and couldn't believe that he wrote it.

He wondered if he had prepared it a long time ago, but the first solution was too unconventional, and he had to look at it for a long time before he had an idea.

He also looked up information on the Internet, but he hasn't seen this solution on it!

So he suspiciously handed Zuo Yan the next question, which was a very high-level function problem he deliberately found in order to elevate himself.

Unexpectedly, he handed it to Zuo Yan, and Zuo Yan began to wipe the blackboard after looking at it for a few seconds.

Then, in less than two minutes, Zuo Yan wrote the answer to this question on the blackboard, leaving the sluggish Zhao Qiang back to his seat.

Jingle bell .......!

It was still the bell that seemed to be late for the end of class, and it woke up Zhao Qiang in a sluggish state.

He took out his mobile phone and took a picture of Zuo Yan's solution on the blackboard, because now he has not been able to bring Zuo Yan's solution ideas, and he needs to go back and take a good look.
