Chapter 287

This young man knew Xu mang. When he was in class the day before yesterday, he told Xu mang that this is a Bo class. He is a good man.

"Ah?"

"Is it?" Xu mang embarrassed but not politely said: "may be sleepy, said here is a Bo ban?"

"How many more do you want?" The student said.

"Oh..."

"is there too many students in this Bo class?" In Xu Mang's conjecture, there should not be so many doctors. Good guy... I saw at least 80 or 90 people in the multimedia classroom before.

There are so many doctors?

It's not worth it, right?

"It's not just mathematics. There are many other departments." The young man, who was not a young man, asked Xu Mang, "did you come here to listen?"

"Well!"

"What... They say that the quality of teaching in the Bo class is high." Xu mang said with a smile: "I felt it the day before yesterday, and it's really different... In addition, the professor has just arranged the problem, I'll see how strong the doctoral students are."

Hearing Xu Mang's words, the young man said with a bitter smile: "that problem... I believe that almost no one can do it."

"Ah?"

"Oh..." Xu mang nodded: "it's really difficult."

After that, Xu Mang and the young man got to know each other. They thought he was a Ph.D. student in the Department of mathematics, but they made a mistake. They studied economics.

"My girlfriend studies Chinese economy and trade." "I thought I didn't need to learn mathematics to study economics," Xu said. "I didn't expect to learn economics. I still need to master mathematics... My brother is tired."

"It's ok..."

"make a living." The young man gave a bitter smile and said in silence, "I'm sorry, I'm more realistic."

"It's OK."

"I'm more realistic than you are." Xu mang showed a smile that he didn't want to beat. He said quietly, "my brother, doctor of Economics... There are many places to work in the future. It is estimated that there is a million annual salary."

Of course,

Xu mang is just saying it casually. He doesn't know how much money he will give, but it's always right to say higher.

People like to listen to good ones.

At first, Xu mang wanted to help his father-in-law to recruit the young man. But he thought carefully... People might not look up to him. What should he do if the other side asked for an important position?

I can pat my chest, but all the problems are left to my father-in-law. I'm afraid at that time... I and Xiaoman will come to an end.

Alas...

"brother?"

"Do you think there is a way out for people like me to study economics?" Xu asked curiously.

"..."

"brother, don't make trouble!" The young man said with a smile.

Xu Mang: soon,

soon,

the number of students in the multimedia classroom gradually increased, and soon the number reached about 80.

Yesterday, after all, there was no reaction to many strangers in the second day.

"Have you worked out that question?"

"No... it's too difficult. At first, I thought it was a simple power series convergence problem. Who knows when the solution reaches a quarter, it's not!"

"Yes, yes, it's not a power series convergence problem at all... Professor, this is a trap deliberately set up."

"Ah... You are also stupid. Since the professor dares to give you two days, it means that you can't get a week's time!"

Suddenly,

there was a howl in the classroom.

Some people are indifferent,

they belong to the Department of mathematics, but it doesn't matter. They have done it, but they don't know if it is right.

The professor came in with a textbook.

Due to the lack of time, the professor did not attend class, but the students at the bottom were quiet.

At this time,

Xu mang received a call.

It's Xiaoman.

"..."

"hello Xu mang sneaked out of the back door and asked in a low voice, "what are you doing?"

"Where are you dead?" Yang Xiaoman said angrily: "early in the morning, I found you were not there. Did you sneak into other people's classrooms to make trouble?"

"Xiaoman..."

"in fact, I'm not the kind of person you think I am." Xu mang helplessly said: "I am a good man."

"Go away!"

"I went to the competition, in short, be a good man!" Yang Xiaoman told a, and then hung up the phone.

WellThis short girl is really eager to control!

Xu mang can understand why Xiaoman is like this, there is no other reason, is that I am really too handsome.

Sneaking back to the classroom again,

after a minute, the class began.

"Cough!"

"Let's talk about the teaching content first, and then leave half of the time to talk about the topic the day before yesterday." Said the professor.

The words

caused discomfort to all the people present.

Half the time?!

Sure enough, the difficulty of this topic is unimaginable.

Hearing the professor's words, most people's emotions gradually subsided. In fact, it's not that they won't, but that the topic is too difficult.

Balance, balance.

At this time,

at this time, Xu mang took a look at the man beside him and found that he was relieved by a long breath. After a little thinking, Xu mang thought that the elder brother might have re affirmed his IQ.

It's not stupid,

it's that the topic is too difficult.

Class,

is very boring.

Xu mang is about to fall asleep. The waves of sleepiness are constantly scouring the beach of consciousness. Fortunately, Xu mang holds back and secretly takes out his mobile phone.

Because the account number of King glory was closed for a week, Xu mang can only play the legend of furnace stone. After updating the game version, Xu mang found that a lot of orange cards had been issued recently.

What to do?

Krypton!

Ka Ka Ka, Xu mang krypton 20000.

In fact, Xu mang doesn't like playing with Firestone. What he likes is the process of opening the card inside, especially "Wow! Golden Legend! " It can make people feel happy.

It's a pity...

Xu mang is a non chieftain, not a very non chieftain.

However, such a person has become the heart of the emperor of Europe.

This is not,

it took nearly 20000 yuan to show the picture of three eggs once.

Screenshots,

were sent to the game group.

Gentle and easygoing pastor (Xu mang): three eggs wrapped in a free card [picture]

and then the group exploded.

Xu mang saw all kinds of words from the members of the group, all around the word "ouhuang niuqiang", and then showed a happy smile. The 20000 yuan was really worth!

"This classmate!"

"Smirk what?" The professor glanced at Xu Mang and saw that he was so stupid that he couldn't stop laughing. He said on the spot, "pay attention to classroom discipline."

"Oh..."

Xu mang quickly put away his smile and put on a serious look.

Soon,

at last, Xu mang slipped away to the toilet. However, when he came back, there were three or four groups of people in the classroom.

"What's the situation?"

"Is it because the class is boring and the students are fainting?" Xu Mang in line with the mentality of eating melon, hastily gathered up, the original is everybody is discussing the topic, is also... Immediately the professor wants to test the student's achievement.

In class,

the students returned to their seats.

The professor in front of the platform asked, "who made the question the day before yesterday?"

In a word,

scattered, three or four people raised their hands, and they were all from the Department of mathematics.

In the face of this situation, the professor has no complaints. After all, the difficulty is there. If all of them are solved, it does not mean that there is a problem with his own level.

"Little money."

"Tell me about it." The professor said to a student.

Then,

the student named Xiao Qian came to the platform, inserted U inventory to open the document, and began to explain his problem-solving process.

"Here..."

"there..."

Xiao Qian's words flew up, and the students at the bottom listened very carefully. But Xu mang was the only one who was confused and confused.

What is he doing?

Why don't you understand?

Oh, my God!

Is it because my business ability is not good again?

Don't say... Xu mang really can't understand what he is talking about. The confusion of logic and the complexity of the process make people disgusting.

Ten minutes later,

the little Qian finally finished speaking, and then he clapped with applause. Although he didn't know what had just happened, it was a matter of courtesy to respect other people's labor achievements.

The professor was expressionless, and then called the next classmate, then another one, and both of them were...

Xu Mang: (﹤)

What's the situation?

In fact,

the answers of these people are all correct. However, almost everyone went around a large circle and solved the problem in a very complicated way.

It's a little time-consuming and laborious.

Sure enough,"The answer is right, but there is something wrong with the process and it is not concise enough," the professor said

Then

the professor began to analyze this power series convergence problem for all present.

"First of all, don't be blinded by the topic." The professor said: "in the future, you will encounter a lot of such situations. It seems that the problem of power series convergence is actually another problem, but you will find that the final answer is back to the convergence of power series."

"..."

"..."

"

"... "

Professor,

you are a little simple!

This is clearly a fusion of a variety of elements in it, but once in, there is no way out.

In the next 20 minutes,

the professor analyzed the pitfalls of this problem and the matters needing attention in detail. Xu Mang and professor had the same views. All the problems were in these points. As long as we straightened out their respective logic, we could almost solve the problem.

It seems that...

I don't need myself today.

However,

things are far less simple than Xu mang imagined.

Then,

the professor began to solve problems for the students on the spot. In the previous steps, there was no accident, almost the same as Xu Mang's, but at a very critical point, Xu found that there was a problem in the professor's problem-solving process.

There is no mistake.

but it will become cumbersome later.

Sure enough,

after a problem appeared in the middle, the professor's problem-solving process was redundant. There were about... Seven steps that were redundant.

In fact, this is already a standard process, but for Xu Mang, it can be simplified a little more to make it more perfect.

"That's all the process." Finally, the professor wrote an answer, and said without expression: "this topic needs to pay attention to logical thinking, and find the corresponding balance point on each key transformation."

"All right."

"Off..."

the professor was about to say "class over" when he was interrupted by a student.

"Professor!"

"I think there are some flaws in your solution." Xu mang stood up and said to the professor, "your process is not simple enough."
