Chapter 449

The bell rang and an old professor with thick glasses came in.

The old professor put down the book and said, "today is the first day. I will not call the roll and inform the students who have not arrived. If you're caught skipping three times this semester, you'll lose the course

"Teacher, no one in our class is absent today. And there are more people! " In order to vent his dissatisfaction, Zhou Guangwen stood up again, glanced at Shen Lang and said, "Liu Qingyi has brought a boy here. This is the classroom. Should we let the redundant people leave?"

"Oh?" The old professor took a look at Shen Lang.

Liu Qingyi got up and said, "teacher, he is my friend and is here to listen in. The school doesn't forbid outsiders to listen. Should it be allowed? "

"Teacher, it's out of order." Zhou Guangwen frowned.

The old professor said in a deep voice: "there is no need to care about this kind of rule. If you want to listen, you can. This kind of attitude is very good, learning is endless. Well, don't waste time on it. Please take out your textbooks. Today we are going to talk about a more difficult formula. "

The old professor began to lecture, and Zhou Guangwen was in a bad mood.

Shen Lang was idle and bored, and listened.

Liu Qingyi was impatient after listening to it for a while. She covered her face with her textbook and talked to Shen Lang in a low voice. She looked cute.

After contacting Liu Qingyi for some time, Shen Lang also found that she belonged to the type of external cold and internal heat.

"This is the formula. We should all understand it? OK, let's do a question to consolidate it The old professor took the book and wrote down two questions on the blackboard. He said to the students, "these two problems are a little difficult. It's nothing if you can't solve them. After all, the formula is too complicated. However, want to take an examination of graduate students or pay attention to carefully look at. "

The students in the class looked at the questions on the blackboard with confused expressions.

These two problems are so difficult that few people in the class can solve them.

Only a few Zhou Guangwen level figures, racking their brains, want to be the first to solve this problem.

For some Xueba, this is equivalent to a kind of competition.

Shen Lang took a look at the title with great interest and kept it in mind.

After ten minutes, Zhou Guangwen was the first to stand up and said, "teacher, I have worked out. Is the answer to the first question 1?"

"Oh, you've worked out a one!" The old professor laughed and said with appreciation, "you are right. The answer to the first question is really equal to 1. It seems that you should have made this formula clear. If you take the postgraduate entrance examination in the future, this formula should not be difficult for you. "

Many students cast an exclamatory look to Zhou Guangwen, who can solve this kind of problem, and is worthy of learning hegemony.

"In fact, it's not difficult to solve this problem. You just need to calculate it carefully." Zhou Guangwen said with a face thumping.

After that, he also glanced back at Shen Lang and said, "I think that all the students who have just listened to the lecture can work out this problem, and so can the student who is listening to him."

All the students looked at Shen Lang, and the old professor also looked at him. However, the old professor did not hold much hope for Shen Lang. This kind of question is very difficult originally, you expect a person who comes to listen on the first day to be able to solve this kind of question, that is just like a fool talking about a dream.

Zhou Guangwen was trying to find Shen Lang's trouble. He said directly, "what's your opinion on this question, this listening classmate?"

There was a burst of laughter from the whole class.

Shen Lang did not speak. Liu Qing wrinkled her eyebrows and stood up and said, "what do you mean, Zhou Guangwen?"

Zhou Guangwen saw Liu Qingyi staring at himself coldly. He felt that he and Liu Qingyi had no possibility. He just broke the jar.

"It's not interesting. I just want to see if your friend has heard the effect." Zhou Guangwen was full of resentment.

The old professor waved his hand and said, "well, let's not discuss this matter. Let's take a look at the second question, the second question. Has anyone worked out the answer? "

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

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

"I said, this classmate, how do you work out such a precise number?"

"That is, those who have been to university should know the law of high mathematics, right? Generally difficult questions, the answer is very simple, which has such a complex

"Yes, with the decimal point. You are too good at it."

Everyone laughed, but no one noticed. The old professor's face on the platform suddenly froze.

Liu Qingyi did not know why Shen Lang suddenly opened his mouth, but she vaguely felt that Shen Lang should not be talking nonsense.

But such a difficult question, Shen Lang did not calculate, it is impossible to get a real answer.

"Teacher, I think the answer to this question should be 2." Zhou Guangwen said that he had been working hard on the problem just now, and he had a general result in his mind.The old professor just regained his mind, scratched his head and said, "if the answer is 2, this question can get half of the score."

Zhou Guangwen's face is full of contentment. It is difficult to solve this problem in less than ten minutes. He can get half of the score in about five minutes, and he feels very good about himself.

Zhou Guangwen felt that in terms of knowledge, he has been very NB, if others do not know that he has such a cow B, this is a very painful thing!

So he likes to show himself.

"Well, it's just half the score." Guan Jing hums a way, she is a bit not used to Zhou Guangwen's face.

The old professor took a deep look at Shen Lang and said, "in fact, the real answer to this question should be 2.2. In 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 a full score. "

At this point, the old professor's voice stopped 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 15 points."

Except Qiao Xing, who is sleeping on the table, all the students in the class show a shocked expression.

is as like as two peas, 2.23.

All the students looked at Shen Lang again, and the former ridicule disappeared and was replaced by surprise and shock. Liu Qingyi's boyfriend is also too powerful, can actually calculate the result so accurately!
