Jiang Han hurriedly made a silent gesture: "Shhh, don't ask, it's annoying to ask too much." ”

“？？？”

Zhou Qinqin was trembling with anger.

Why does this person owe it so much?

"Jiang Han!" she instantly raised her tone and glared angrily.

"What's wrong?"

Zhou Qinqin only felt the green tendons on her head bulge, "Do you know the difference between taekwondo and Muay Thai?"

Jiang Han subconsciously asked, "What's the difference?"

"It doesn't make a difference, as long as you are ruthless, you can be sent to the hospital. Zhou Qinqin said hatefully.

“......”

Seeing Zhou Qinqin's angry eyes, she looked like she was going to shave herself alive...... Jiang Han hurriedly said, "What question did you want to ask just now?"

Zhou Qinqin glanced at him, smoothed out the anger in his heart a little, and then said, "I want to ask if you have solved the problem given to you last time." ”

"It's not that it was solved a long time ago, but it was solved at the time, but I didn't have time to talk about it. ”

Zhou Qinqin didn't believe it, "Really?"

Before she knew that he was a freshman, she was a little confident that Jiang Han would be able to solve it.

But after knowing that Jiang Han was a freshman, she didn't believe it at all.

She took this question to the Q&A room and asked Professor Wu, who said that this is a topic that only graduate students will study.

If you can't use it for an undergraduate, you can't take the exam.

And Professor Wu patiently explained the topic to her in the end, but she still didn't understand it until now.

And Jiang Han is just a freshman who has just entered the school, even if he has taught himself all the courses of linear algebra and learned it well, this question is not something he can solve.

Jiang Han said: "Yes!"

"Then how about you explain it again and show me?" Zhou Qinqin sneered in her heart, what are you still pretending to be?

If you give your senior sister a soft face, won't I let you go?

Since you want to pretend, then let you pretend again.

If you can't solve it, then don't blame the senior sister for doing it to you.

Senior sister is just one excuse to do something to you now......

"Hmm......" Jiang Han frowned and muttered for a moment.

To be honest, he didn't really want to figure it out.

That problem is quite tedious to solve and takes a lot of time. And I have to review the modern history and wait for Monday's exam......

"Actually, if you want to go to graduate school, you don't need to study this kind of difficult question......"

Zhou Qinqin said decisively: "But I want to learn." ”

"Alas, okay, since you humbly ask for advice, then I will teach you reluctantly, let's hurry up. ”

Saying that, Jiang Han pulled Zhou Qinqin to a table where there were not many people sitting, and then took out the topic from his backpack that he wanted to throw away that day but didn't make it, and spread it out on the table.

"Well, I'll just say it once. ”

Jiang Han picked up the pen and first analyzed the backbone of the topic for Zhou Qinqin, and then began to explain.

After talking for about ten minutes, the general solution idea of the whole problem has been clarified, and the next thing is to calculate and solve, but he doesn't plan to do this part, but plans to leave it to Zhou Qinqin to solve it himself.

"How's that? Understood?"

“...... Almost. Zhou Qinqin hesitated.

"Now that the idea of solving the problem is clear, will you do the next calculation and solution?" Jiang Han said.

Zhou Qinqin pursed her lips, to be honest, Jiang Han just talked about the topic, and she didn't understand much at all.

The main thing is that Jiang Han always likes to jump steps.

And don't give her time to think at all.

So much so that he jumped to the next step before he fully thought about the previous step.

She found that she couldn't keep up with Jiang Han's train of thought at all.

"I want you to explain it to me. She said.

"Do you want me to solve this?" Jiang Han was a little dissatisfied, "Don't you understand? I still have to do the rest of the calculation and solution? It's just a very simple mathematical integral operation." ”

Zhou Qinqin's eyes widened, and she was unreasonable: "I just want to see you solve it, can't you?"

"Okay, okay!" Jiang Han was a little helpless.

So I spent more than ten minutes talking about the detailed solution steps of the whole question.

"That's for you. ”

Zhou Qinqin took the steps to solve the problem handed over by Jiang Han, and didn't look at the detailed steps, because she seemed to find that she couldn't understand it at all. So she glanced directly at the final answer and compared it with the answer given by Professor Wu......

It turned out to be exactly the same!

Zhou Qinqin's eyes widened instantly!

He made it.

He really did it!

I did it in front of myself, without looking through the information or searching the Internet!

"How did you really do that?"

Jiang Han said a little impatiently: "Of course I made it with my brain. ”

Zhou Qinqin was speechless for a moment, and looked at Jiang Han in a daze.

He...... Is it really just a freshman?

Zhou Qinqin began to doubt life, what kind of demon is he?

What did Qingda receive this year?

What is the purpose of making such people exist?

Is it just to get the mentality of our people?

Or is it to remind yourself all the time that you are just a scumbag?

"If nothing happens, I'll go!"

Zhou Qinqin came back to her senses in an instant, "Where are you going?"

Jiang Han said: "Go and review." ”

Zhou Qinqin frowned, "Isn't it good to review here?"

Jiang Han said lightly: "I still have to review today, I don't want to teach others math problems today." ”

“？？？”

It's the same as if I had to ask you a question.

Zhou Qinqin's face sank, and she was about to get angry, only to hear Jiang Han's fearless reminder: "Don't forget that you cleaned the library for a week last time......

In an instant, Zhou Qinqin was even more angry, but she didn't dare to say it.

"That, classmate......"

Suddenly, a very careful voice came, Zhou Qinqin and Jiang Han looked over when they heard the sound, and saw that it was a girl wearing a wide dress and long hair, looking at Jiang Han cautiously.

"It's you. ”

Seeing that it was Lin Youwei who bumped into her around the corner before, Jiang Han smiled and asked, "Are you also here to review?"

"Hmm......" Lin Youwei nodded.

"Is there something wrong?" Jiang Han asked with a smile.

"I ...... I have a problem that I can't solve......" Lin Youwei secretly saw Jiang Han helping the classmate next to him solve a problem that seemed to be difficult, so she planned to ask Jiang Han for a problem that she hadn't solved all morning.

But she seemed to have heard Jiang Han say that she wanted to review ...... She was afraid that she would delay other people's review.

"Is it a math problem?" Jiang Han asked.

"Hmm. ”

"Well, I don't have anything to do right now, so you can show me the title. ”

Zhou Qinqin: "???"

Lin Youwei glanced at Zhou Qinqin, who had a somewhat strange face, and said with some embarrassment: "Okay, thank you, thank you." ”

"No thanks. Jiang Han took the question with a smile and looked at it carefully.

After Jiang Han thought about it for a while, Lin Youwei asked out loud: "How is it, this topic ...... Will you?"

Jiang Han raised his head, smiled confidently, picked up a pen and spun it in the air, "Of course it will, you must know that no one knows mathematics better than me!"

"Can you teach me?"

"Absolutely. ”

Zhou Qinqin, who was standing on the side, instantly darkened his face.
