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, so I won't name it anymore. I'll notify the students who haven't arrived.

If you are caught and missed three times this semester, you will be out of this subject.

"Teacher, no one is absent from our class today.

And there are more people!" In order to vent his dissatisfaction, Zhou Guangwen stood up again, glanced at Shen Lang, and said, "Student Liu Qingyi brought a boy here. We are in class. Should we let 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 to it.

Learning is endless, and this kind of attitude of being willing to study is good.

OK, don't waste time on this matter.

Please come up with the textbook, and today we will talk about a relatively difficult 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 contacting Liu Qingyi for a while, Shen Lang also found that she was cold on the outside and hot on the inside.

"This is the formula, everyone should understand it, right? OK, let's do a question to consolidate it now.

"The old professor took the book and wrote down two questions on the blackboard, saying to the students: "These two questions are a bit difficult, and it's nothing to solve them, after all, the formula is too complicated.

However, students who want to take the postgraduate entrance examination should still 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. If they can solve such a problem, they are worthy of being a top student.

"In fact, this question is not difficult, you just need to calculate it 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 just 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 together, 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 it is a dream to expect someone who comes to listen to this question on the first day.

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 and stood up and said, "Zhou Guangwen, what do you mean?" Zhou Guangwen saw Liu Qingyi staring at him with cold eyes, and his mood was immediately terrible. Anyway, he felt that there was no possibility between him and Liu Qingyi, so he simply gave up.

"It's not interesting, I just want to see if your friend heard the results.

"Zhou Guangwen said with a resentful look on his face.

The old professor waved his hand and said, "Okay, okay, everyone should not 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 to this classmate, how did you calculate such accurate numbers?" "That's right, those who have been to college should know the rules of advanced mathematics, right? Generally, the answers to difficult questions are very simple, but they are not so complicated.

"Yes, you still have a decimal point. You are 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 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's face was full of pride. This kind of problem would be difficult to solve without more than ten minutes.

He only took about five minutes to get half of his score, and he felt 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 liked 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 arrogant 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.

If the result is 2, you can get half of the score.

If the answer is 2.2, you can get the full score.

"At this point, 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 Qiao Xing, who was sleeping on the table, all the students in the class showed shocked expressions.

It's really 2.23, exactly the same as what Shen Lang said.

The students looked at Shen Lang again, and the previous ridicule and ridicule disappeared, replaced by surprise and shock.
