Chapter 449: 449

When the bell rang for class, an old white haired professor with thick glasses came in.

The old professor put the book down and said: "today is the first day, I will not call the roll, to inform the students who did not arrive. If you're caught skipping three times this semester, you're out of school. "

"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 brought a boy here. We are in the classroom. Should we let the extra people leave?"

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

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

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

The old professor said in a deep voice: "this kind of rule doesn't need to be cared about. There is no end to learning. This kind of attitude is very good. Well, don't waste time on this. Please take out your textbook. Today we are going to talk about a more difficult formula. "

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

Shen Lang is idle and bored. He also listens.

Liu Qingyi was impatient after listening for a while. He covered his face with his textbook and talked to Shen Lang in a low voice. His playful appearance was a little cute.

Contact with Liu Qingyi for a while, Shen Lang also found that she belongs to the type of external cold and internal heat.

"That's the formula, you all know? OK, let's do a question now to consolidate it. " The old professor took the book and wrote down two questions on the blackboard. He said to the students, "these two questions are a little difficult. It's nothing if you can't solve them. After all, the formula is too complex. However, the students who want to take the postgraduate entrance examination should pay attention to look carefully. "

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

These two questions are too difficult. Few people in the class can solve them.

There are only a few people of Zhou Guangwen's rank who are trying their best to solve this problem first.

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

Shen Lang took a look at the topic with interest and remembered it in his mind.

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

"Oh, you've figured out one!" The old professor smiled and said with appreciation, "you are right. The answer to the first question is indeed equal to 1. It seems that you should have made this formula clear. If you take the postgraduate entrance examination later, this formula should be difficult for you. "

A lot of students cast an astonishing look at Zhou Guangwen. They can solve this problem. They are worthy of learning hegemony.

"In fact, this problem is not difficult. It only needs to be calculated by heart." Zhou Guangwen said with a thumping face.

After that, he glanced back at Shen Lang and said, "I think this question can be worked out by all the students who have just listened carefully, and by the students who have listened."

All the students looked at Shen lang. the old professor also looked at him. But the old professor didn't have much hope for Shen Lang. This kind of question is very difficult originally. You expect a person who comes to the audience on the first day to solve this kind of question. It's just like a dream.

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

There was a burst of laughter from the class.

Shen Lang didn't speak. Liu Qing frowned and stood up and said, "what do you mean, Zhou Guangwen?"

When Zhou Guangwen saw Liu Qingyi staring at himself with cold eyes, he was in a terrible mood. Anyway, he thought that he and Liu Qingyi were not possible, and he broke the pot.

"It's not interesting. I just want to see if your friend can hear the effect." Zhou Guangwen said with resentment on his face.

The old professor waved his hand and said, "OK, let's not talk about this. Let's see the second question, the second question. Has anyone figured 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 student, how do you work out such a precise number?"

"That is, those who have gone to university should know the law of high number? Generally difficult questions, the answers are very simple, which has such a complex

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

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

Liu Qingyi also didn't know why Shen Lang suddenly opened her mouth, but she felt vaguely that Shen Lang should not be talking nonsense.

But for such a difficult problem, neither Shen Lang nor Shen Lang can work out the real answer.

"Teacher, I think the answer to this question should be 2." Zhou Guangwen said that he had been calculating the problem, and had a general result in mind.

The old professor just got back to his senses, scratched his head and said, "if the answer is 2, this question will get half of the score."

Zhou Guangwen's face is full of complacency. This kind of problem is hard to solve in less than ten minutes. He only takes about five minutes to get half of the score. He feels very good about himself.

Zhou Guangwen thinks that in terms of knowledge, he has been very NB. If others don't know that he has such a good B, it's a very painful thing!

So he likes to show himself.

"Well, that's half the score." Guan Jing said, she can't stand 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, this kind of question is generally regarded as a bonus item. 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 paused and continued, "but the perfect answer is 2.13. If you can get 2.23, you can get a full mark up, usually 15 points."

Except for Qiao Xing, who was sleeping on the table, all the students in the class showed a look of shock.

is as like as two peas, 2.23.

When the students looked at Shen Lang again, the previous sarcasm and ridicule disappeared and replaced by surprise and shock. Liu Qingyi's boyfriend is too fierce. He can calculate the result so accurately!
