The class bell rang, and a white-haired old professor wearing thick glasses walked in.

The old professor put down the book and said, "Today is the first day, I won't name it anymore, I'll notify the students who haven't arrived. If I'm caught and skipped three times this semester, then this class will be dead." "Teacher, no one is absent from our class today. And there are more individuals!" In order to vent my dissatisfaction, Zhou Guangwen stood up again, glanced at Shen Lang, and said, "Student Liu Qingyi brought a boy here. We are class, aren't we?

Should the extra people leave?"

"Oh?" The old professor looked at Shen Lang.

Liu Qingyi stood up and said, "Teacher, he is my friend, and he is here to listen. The school does not prohibit outsiders from listening. It should be allowed, right?"

"Teacher, this is too unruly." Zhou Guangwen frowned. The old professor said in a deep voice: "There is no need to care about this kind of rule, of course you can listen. Learning is endless, and this kind of attitude of being willing to study is good. Okay, don't waste time on this matter. Please take out your textbooks, we will talk about it today.

A hard formula.”

The old professor started giving a lecture, and Zhou Guangwen was in a very bad mood.

Shen Lang was bored and started to listen.

However, Liu Qingyi became impatient after listening for a while. She covered her face with a textbook and spoke to Shen Lang in a low voice, her playful look a bit cute.

After a while of contact with Liu Qingyi, Shen Lang also found that she belongs to the cold outside and hot inside. "This formula is like this, everyone should understand it, right? Okay, let's do one question now to consolidate it." The old professor took a book and wrote two questions on the blackboard, saying to the students: "These two questions are a bit difficult, and they can be solved.

It doesn’t matter if you don’t come out, after all, the formula is too complicated. However, students who want to take the postgraduate entrance examination should pay attention to take a closer look.”

The students in the class looked at the topics on the blackboard and all showed confused expressions.

These two questions are too difficult, and few people in the class can solve them.

There are only a few Zhou Guangwen-level figures who racked their brains to be the first to solve this problem.

For some academic masters, this is equivalent to a competition.

Shen Lang looked at the topic with interest and remembered it in his heart.

It took ten minutes for Zhou Guangwen to stand up first and said, "Teacher, I calculated it. Is the answer to the first question 1?" "Oh, you calculated it!" The old professor smiled and praised, "You calculated it correctly. The answer to the first question is indeed equal to 1. It seems that you should have figured out this formula. If you take the postgraduate entrance examination in the future, this formula should not defeat you.

”

Many students cast amazement at Zhou Guangwen. Being able to solve such a difficult problem is worthy of being a top student.

"Actually, this question is not difficult, you just need to calculate carefully." Zhou Guangwen said with a proud look on his face.

After saying that, he glanced back at Shen Lang and said, "I think all the students who have listened to this question should be able to calculate it, and the students who were listening to it can also calculate it." The students looked at Shen Lang with all their eyes, and the old professor also glanced at him, but the old professor did not have much hope for Shen Lang. This kind of question is difficult, and you expect a person who came to listen to this question on the first day can answer this question. That's no different.

So it was a foolish person.

Zhou Guangwen wanted to deliberately cause trouble for Shen Lang. He said directly: "This classmate who was attending, what do you think of this question?"

A burst of laughter came from the whole class.

Shen Lang didn't say anything, Liu Qingyi frowned, stood up and said, "Zhou Guangwen, what do you mean?"

Zhou Guangwen felt very bad when he saw Liu Qingyi staring at him with cold eyes. Anyway, he felt that there was no possibility of him and Liu Qingyi, so he simply gave up.

"It's not interesting, I just want to see if your friend has heard the results." Zhou Guangwen said with a resentful look on his face.

The old professor waved his hand and said, "Okay, okay, don't discuss this matter. Let's take a look at this second question, and has anyone figured out the answer to the second question?"

Shen Lang said coldly: "The answer to this question is 2.13."

As soon as these words came out, the class was quiet for a while, and then a group of students burst into laughter.

"I said, this classmate, how did you calculate such accurate numbers?"

"That is, those who have been to college should know the rules of advanced mathematics, right? Generally, the answers to difficult questions are very simple, so how can they be so complicated?"

"Yes, you're still with a decimal point. You're too capable."

Everyone burst into laughter, but no one noticed that the old professor on the podium's face suddenly solidified.

Liu Qingyi didn't know why Shen Lang suddenly spoke, but she vaguely felt that Shen Lang shouldn't be talking nonsense.

However, Shen Lang didn't even calculate such a difficult question, and it was impossible to get a real answer.

"Teacher, I think the answer to this question should be 2." Zhou Guangwen said. He had been lying on this question just now, and he had a rough result in his mind.

The old professor then came to his senses and scratched his head and said, "If the answer is 2, this question can get half of the score."

Zhou Guangwen looked proud. This kind of problem is difficult to solve without more than ten minutes. He can get half of the score in just about five minutes, and he feels very awesome.

Zhou Guangwen felt that in terms of knowledge, he was already very NB. If others didn’t know that he was so awesome, it would be a very painful thing!

So he likes to show himself very much.

"Hmph, isn't it just half the score?" Guan Jing snorted. She was a little disgusted with Zhou Guangwen's proud face. The old professor looked at Shen Lang with great meaning and said, "Actually, the real answer to this question should be 2.2. During the postgraduate entrance examination, such questions are generally used as bonus points. The result is 2, and you can get half the score. Answer

If the case is 2.2, you can get the full score.”

Speaking of this, the old professor paused for a moment and continued, "But the perfect answer is 2.13. If you can get 2.23, you can get a full bonus, usually fifteen points."

Except for Qiao Xing, who was sleeping on the table, all the students in the class showed shocked expressions.
