This person is really a snob, so gentle to the top student, but the same is true to Li Che, who is a scumbag.

Li Che was helpless, and under the gaze of the whole class, he had to slowly walk over to the blackboard.

And Tang Ning, a scholar, really had no idea, so he had to turn around and leave, ready to return to his seat.

Li Che looked up at Tang Ning, he thought that Tang Ning would put the chalk on the lectern.

Suddenly, Tang Ning stopped in front of Li Che, and then took the initiative to hand him the chalk in his hand.

No way!

The goddess actually took the initiative to hand him the chalk head.

For the first time, Li Che approached this goddess at close range in such a positive way, and he was inevitably a little excited in his heart.

Li Che carefully took the chalk and couldn't help but say, "Thank you!"

Tang Ning didn't give any response and returned to his seat.

Li Che smiled casually, and didn't care about Tang Ning's attitude, which was expected.

Coming to the blackboard, Li Che glanced at the question again.

Some people want to see Li Che's jokes, and some people express sympathy.

Li Che didn't rush to put pen to paper, but turned to look at Luo Shuangshuang, the math teacher next to him.

Without waiting for Li Che to speak, the black-faced old demon said: "If you don't know how to do it, just say it, don't waste everyone's time." ”

"Black face, uh, no, it's Mr. Luo. I want to ask, do I only write one solution to this problem, or do I write all the solutions?" Li Che said with an innocent face.

Hearing Li Che almost call out "black-faced old demon", the male classmates in the class couldn't help but almost laugh, but because of the old demon's Y power, they didn't dare to laugh, and their faces turned red one by one.

"Isn't there more than one?Okay, then you can write everything you know!" The black-faced old demon's face turned pale, and it was obvious that she was about to be angry by Li Che's seemingly casual words just now.

In Luo Shuangshuang's opinion, Li Che must have deliberately called her that just now.

Squeak••Squeak•••

Li Che didn't say anything more, took the chalk in his hand and quickly wrote on the blackboard.

The people in the audience slowly quieted down, but they didn't expect this Li Che to really be able to write something.

Halfway through his first solution, the audience began to whisper again.

The people who studied well read Li Che's answer and slapped the table one after another, "Damn! yes! Why didn't I think of using this method." ”

"yes, these formulas are just right!"

Tang Ning was also a little surprised on her face, she had naturally seen that Li Che's method of solving the problem was correct.

The school girl was a little surprised.

"This Li Che really knows how to do this question? Then why is he so bad in every exam? It seems that he is always at the bottom of the class. Could it be that he used to deliberately get low grades. What a strange guy. “

This naïve school girl didn't know that he had a trace of curiosity about this boy who was a little handsome, used to be a scumbag, and now he didn't know what strength it was.

Now she doesn't know that if a woman becomes curious about a man, then what will often happen in the future is hard to say.

Look at those students who are poor in learning, they can't understand Li Che's answer at all.

"Is what he wrote right, is this Li Che scribbling?"

"I don't know, but look at those who study well, their expressions seem to be saying that Li Che wrote correctly. “

"I look like it, is Li Che really a scholar. “

"I remembered that when Li Che entered the first year of high school, he was one of the top ten in the whole grade. He must have been pretending to be for the past three years, in order to make a splash in the college entrance examination. “

"Yes, it's possible, this kid is too scheming. “

Li Che's hearing has improved several times now, and he can hear the whispers of the students in the audience clearly.

In this regard, Li Che couldn't help but feel a little wronged in his heart, "This classmate, you really wronged me, in the past three years, I have focused all my energy on online novels, and I really haven't studied." “

However, he did not stop in his hand and continued to write.

Soon, the result of this problem came out, which was "x is equal to 4, y is equal to 3, z is equal to 2".

The black-faced old demon looked at this result with a complicated expression.

Undoubtedly, this answer is correct, because all the steps of Li Che's solution are correct.

Just when everyone was incredible.

However, Li Che did not stop.

Instead, he took a step to the right, continued to write the second solution on the blackboard, changed his thinking, changed the formula, and continued to answer the question.

Oh no!

The fat man sitting in the last row was a little speechless, "Is this still my brother Ah Che?"

"The second kind, look, he really knows the second way?!"

"I saw it, let's take a look, right?"

A girl sitting next to Tang Ning looked at Tang Ning and whispered, "Ning, you said that he used to behave like such a scumbag, did he pretend to be?"

"I don't know, right? Let's see him solve the problem first, and see what kind of thinking he uses in the second way?"

Tang Ning didn't communicate too much with her tablemates, after all, she never talked about others behind her back.

This time, it is a little more complicated than the first solution, and there are several more formulas used than the first one. But Li Che still writes very clearly, at least those students who have some mathematical foundation can understand it at a glance.

Soon, the second solution was completed.

At this time, the face of the black-faced old demon was a little hot, and he just said that he would not go down.

But now, this Li Che quickly wrote the correct answer.

What's even more slap in the face is that he has more than one answer.

But is that the end of it? However, no.

Li Che still stopped, only to see him move to the right again, and then wrote the third solution.

The black-faced old demon instantly forgot about being slapped in the face, and was shocked instead.

"Can he come up with a third solution, impossible! After I read the standard answer, that is, the first method he wrote, I thought about it for a long time, and then I came up with another one, that is, the second one he wrote, there should be no third way!" Luo Shuangshuang didn't believe that Li Che could still write a third way to solve the problem.

Li Che didn't pay attention to the incredible eyes of everyone, and thought in his heart, since you want to be crazy, let's be crazy to the end!

In the third method, Li Che uses the idea of reverse deduction to solve the problem in reverse.

At first, everyone really didn't understand what Li Che meant.

"What does he mean by that? Does it have anything to do with this question?"

"I don't understand it either, so keep reading. ”

With Li Che presenting little by little.

Finally, the black-faced old demon was the first to see it, "Oh, it turns out that he used the reverse deduction idea, I thought of it at the time, but it was too troublesome, there were too many things to consider, and I couldn't do it at all." Unexpectedly, he could write it clearly. ”

"Ah, I can see it, he's using a reverse push!" I don't know who it is, and I shouted excitedly.

"yes, I can see it too, it's really backwards. ”

"That's too strong, isn't it?"

Tang Ning looked at Li Che's back and sighed in his heart, "With his level, if he can really play in the exam, I'm afraid that the first place in the school will have nothing to do with me." ”

"My good girl, Ah Che, you are my god!" Although the fat man couldn't understand what Li Che wrote, looking at the reactions of the black-faced old demon and his classmates, he knew that his brother had used three methods to solve math problems that he couldn't do in the whole school.

It seems that this fat man is even more excited than Li Che himself.

After writing the third type, Li Che didn't look back, but smiled slightly, "Is this the end?"

Everyone thought that after he finished writing this third method, he would turn around and come back.

All were ready to greet him with expressions of envy, jealousy, and adoration.

Unexpectedly, Li Che took a step to the right again and wrote down the fourth solution vividly.

"No, come back!"

Seeing that Li Che was going to continue writing, the students in the audience were going crazy.

"Li Che, you are a scholar. ”

"What a scholar, phew! My brother Che is a scholar!"

"Yes, Xueshen, Xueba can't express Brother Che's strength anymore. ”

This time, several top students, including the black-faced old demon and Tang Ning, were also a little unable to sit still, everything they could think of and what they couldn't think of had already been written out by Li Che, but looking at his current posture, could he still have any way?

Li Che only paused for a moment, and then began to draw the figure.

"Ah, I see, the fourth method is a combination of geometry and algebra. ”

"Nonsense, people have drawn all the diagrams, it must be a combination of geometric algebra. ”

"You can think of it, or is it not human?"

"Of course it's not a human being, it's a god, it's a god!"

"Yes, it's God, it's terrifying!"

The fourth method, easy to do.

"Okay, Brother Che, go back and accept the worship of the younger brothers!"

"Ahh

"Why did you take another step to the right?"

"He's going to write again?!"

Everyone is not mistaken, Li Che wrote the fifth solution a foot away from the edge of the blackboard.

This time the classroom was completely silent, and no one was talking about anything else.

Everyone, whether they understood it or not, was quietly watching Li Che on the podium.

Watch the chalk in his hand wander smoothly across the blackboard.

The fifth method is the substitution method, which uses some super-outline equations, which are also induced by Li Che himself in the process of reading the book just now.

Therefore, the next kind of thinking may only be understood by the math teacher black-faced old demon, and even those top students will definitely be a little confused.

"We don't think we have learned this equation yet, do we?"

"Yes, but I think Li Che seems to be right. ”

Hearing this, the tablemate next to him looked at him with great disdain, and said, "You still need to see, can the equation I use to be clear?" It seems that this guy has been completely conquered by Li Che.

Well, the fifth method ended perfectly.

Before anyone could react, there was still silence in the classroom.

"Teacher, there's no room on the blackboard..." Li Che turned his head to the black-faced old demon and said.
