Chapter 13

Qin Ze looked in from the door. There was no difference between this classroom and the ordinary classroom. Only the desks and chairs were cleared to the back of the classroom. There were only four or five desks with notebooks. The students in front of the desks either looked up or did their own things with no distractions. Professor Li is over 50 years old. He has white temples and a pair of round glasses. He looks like an old scholar who is very serious and difficult to get along with.

He looked away from the computer and turned to look, "come in."

Qin Ze nodded and went to the platform.

Professor Li helped the mirror frame and looked at Qin Ze: "I'm a junior this year. It's time to practice in the second half of next year."

"Yes, so I want to exercise myself in advance." After finishing, Qin Ze suddenly found that he did not have a trace of nervous mood. According to his past urine, he was examined by the professor's sharp eyes, not to mention his legs trembling. He should be a little stiff, but he was calm and even surprised himself.

Professor Li nodded. "Although your father has said hello to me, we should discuss the matter as it is, and there should be some assessment."

He took out a stack of A4 paper from the drawer, which listed a lot of topics, picked out a few and handed them to Qin Ze: "this is a small part of this scale model, which is relatively simple and easy. You can take it and have a look. I'll give you two hours. You can choose two questions at will and calculate the analytic equation. Liu, give him a pen. "

The girl who opened the door immediately handed in a pen.

Qin Ze did not talk nonsense. He looked around and found that there was no extra seat. He went to the back of the classroom and moved a desk out of the classroom on his own. He was light handed and tried not to make too much noise.

Qin Zepu calculated the equation on the draft paper. Sometimes he looked at the content of the subject. He saw that he wanted to work out the complete equation several times, but he had to push it down and start again.

Mathematical modeling is a very profound knowledge, and what he is doing now is not even mathematical modeling, but a small step in the long march of 25000 Li. Mathematical modeling, also known as mathematical modeling, is an important means to solve practical problems by using mathematical tools. Moreover, the popular point is to use mathematical language and methods to establish "equations" for certain things and phenomena. For example, if a mathematician wants to predict the weather, he can collect data and build a huge mathematical model to calculate the weather of tomorrow.

Of course, it's just a metaphor. Real weather forecasting is much more complicated than that. But the weather bureau is actually a huge mathematical model.

Economics and mathematics are inseparable, and mathematical model is one of the most important and widely used.

Qin Ze calculated for half an hour, and his forehead began to sweat, and he finally felt the right direction. Or the mathematical foundation is too shallow, many formulas have to rack their brains to remember. If Qin Baobao is here, he must hum twice, push it on Qin Ze's head and say, "you give me the dead open, minute minute to finish."

It is said that men are born with strong logic and women are born with sensibility. Therefore, men are strong in science and women are good at arts. But this rule is completely reversed on the Qin family's brothers and sisters. Qin Baobao has been outstanding in mathematics since childhood, and has never dropped out of the top three, claiming to be the queen of science. Some of the most brilliant achievements of Qin Zeke in the national literature contest were won.

Fortunately, he knew that he was not a smart man, and that he could make up for his own incompetence, and that he did not abandon himself, so that he was not baffled by two problems that could block 50% of College Students' wealth.

Time flies. Professor Li, with the help of his assistants, pushes the modeling progress a little bit and sometimes holds small meetings, but all these have nothing to do with Qin Ze.

Two hours later, Professor Li seemed to think of Qin Zelai. He stepped down from the platform and came to his desk. He did not speak. He picked up his paper and looked at it. The answer to the equation was written on the white paper. The handwriting was neat and meticulous, which Professor Li liked at a glance. Look at the draft paper, daub, change, dense calculation formula, there is no blank. Qin Ze's mathematics was trained by the old man with a whip.

"Not bad!" Professor Li nodded, put the paper back on the table, turned and walked back to the platform, "stop what you're doing."

Five or six assistants raised their heads.

"I'd like to introduce a new member, Qin Ze, from class 7 of the Department of finance, your younger brother."

Qin Ze stood up and said politely, "please take care of me."

Scattered applause.

Professor Li said, "Yang Chen, you should take your younger brother with you these days to let him know our project this morning. I'll have classes later. I'll go first. "

A boy in a blue T-shirt and light white slacks nodded and beamed: "yes, professor."

Professor Li left.

Before he came here, the old man had already told Qin Ze in detail that a huge mathematical model could not be done by Professor Li himself. Therefore, he needed assistants, whose salary was 200 yuan a day for a week. When the mathematical model is finished, he can get a thousand four.

Professor Li was not willing to recruit students in school. His assistants were senior interns and would graduate next month. In the face of the old man, he promised to let Qin Ze have a try.

Qin Ze waited for a moment in his seat. Seeing that the schoolmaster named Yang Chen was buried in his work, he took the initiative to go over and called out "Schoolmaster".

Yang Chen took a look at him and took out a pile of materials from the drawer. He said, "look at it yourself first."Qin Ze had to take the information back to his seat and chewed it patiently. A good private equity company should have its own professional market analysts. It can be seen that the private equity company entrusted by Professor Li is not large. To build a complete digital model, a large number of formulas and data are needed. Mathematics is the most rational thing in the world, every step needs to be deliberated. Qin Ze's group is responsible for the yield and risk assessment.

In addition to a not too detailed summary, there are also a series of symbols. Qin Ze seems to have some difficulty. He takes out his mobile phone, searches on the Internet and translates them one by one.

In the blink of an eye, the students in the classroom went to the canteen to solve the problem of food and clothing. Qin Ze wanted to put his energy into studying hard, but he was driven out to eat by the elder sister who was in charge of the key.

Because of the limited time, he ate some food casually and rushed back to the classroom.

The door of the classroom was lying open. As soon as I was about to push the door in, I heard someone inside saying, "brother Chen, what's the new way? We've been working hard for a month, and it's more than a week before the delivery time. Good guy, he's too cold to get in and earn our labor costs. "

The guy who talked is also from Qin Ze's group, so I don't know the name.

Yang Chen snorted, "his father and Professor Li seem to be in the same office. They are related to each other. They come here to have a long knowledge and mix some pocket money."

"Our group is only 10, 000 yuan in bonus, which is more than 1000 yuan, which is enough for half a month's rent."

"Don't you still live in the bedroom?"

"Then you can have two big health care."

"Don't worry. He didn't even know the basic situation of the task today. I will assign some subjects to him at that time. He can't finish it. Ha ha, Professor Li must be unhappy. If you come a few more times, you may kick him out. "

Qin Ze face a black, the heart says these two little red guy. He went downstairs in silence and walked around the teaching building. He sighed that where there were people, there were rivers and lakes. This kind of fighting without swords and swords became more and more cruel after he went to university. No, life is full of fighting. Primary and secondary schools are no exception. At that time, they were young and liked to express themselves in violent ways.

Qin Ze doesn't like this kind of intrigue hidden in the dark. He hasn't adapted to it.

More than ten minutes later, he went upstairs to the classroom, and most of the seniors and sisters came back. The elder sister named "Xiao Liu" smiles at him, and Qin Ze politely smiles back.

There was a professional class at 1:30 p.m. after class, Qin Ze refused his roommate's invitation to open the black online, and plunged into the modeling data pile. Although he is not Qin Baobao's natural science talent, he has one advantage that makes the old man praise him very much: he has calmness in every big event! That's what the old man said.

At five o'clock in the afternoon, Professor Li came back. Each group assigned tasks. Before announcing the end of the day, he thought of Qin Ze.

"How are the information contents of the yield and risk assessment

"I'm a fool, I haven't eaten it yet." Qin Ze said.

Professor Li frowned and looked at Yang Chen: "I asked you to take him."

Yang Chen's face was innocent: "I gave him information, let him ask me casually if he didn't understand, but he didn't have any problems all day long. I thought Qin Ze had a good foundation and understood himself well."

Nima, when did you say that.

Professor Li took a look at Qin Ze and didn't say anything. He announced the end of his work today. However, Yang Chen was disappointed by Professor Li's indifferent attitude. Only Qin Ze can guess his mind. In fact, the modeling is coming to an end. It is true that there is a lack of assistants. However, it is mostly for the sake of the old man that Qin Ze is invited to join the gang. That day, the old man also said implicitly: what do not understand to ask him.

Therefore, it doesn't matter whether Qin Ze is a fool or not. He has his father behind the scenes to help.

Qin Ze asked Yang Chen for information, but he didn't refuse. He handed him a pile of copies. A college student, he could see whether the flowers had come or not?

After the break-up, it was still early, and he spoke on the chat group: "liberated!"

A moment later, Li Liang replied, "come on, come on, we need you to take charge of the overall situation. Mom, you can't take them."

Zhao Ba Liang then replied: "I can't take you, brother with one enemy three, vow not to retreat, a turn back, NIMA, where are your teammates? All my teammates are dead back in the hot spring. "

Then there was Liu Ziqiang: "I will watch you pretend to be forced, do not speak."

Qin Ze mouth hook up, mobile phone back pocket, carrying a shoulder bag, trot to the direction of the Internet cafe.

Familiar location, familiar three animals. With his cigarette in his mouth, he leaned back on the sofa chair. Because of waiting for Qin Ze, Li Liang took time to watch the game video. Zhao Ba Liang opened a small window to watch Liu Ziqiang play with his mobile phone.

On the habit of smoking in the eyes.

"At the end of the month, it's summer vacation. What do you think you're doing. Be careful of your failure. " Li Liang took a hard smoke.

"Earn a little pocket money, always can't let elder sister raise." Qin Ze took out the mineral water from his bag and gave each one a bottle."The modeling of investment is not easy. There are too many factors to consider. How did you feel on the first day?" Relative to the other two, Liu Ziqiang, the best student, unscrewed the lid and took a sip. He asked with a smile.

"It doesn't matter if it's difficult or not. It's just that I'm in a bad mood when I meet a bitch today." Qin Ze make complaints about it.

"You have a story, but I have no wine. Tell me about it? " Li Liangshun invited Qin Ze to join the game in the computer.

"It's just a fool. I'll find a chance to do something with him." Qin Ze skimmed his mouth.

"When the time comes, you must take eight Liang and stab the stupid chrysanthemum with his human cannon." Li Lianggang finished saying, suddenly a fuss called: "neuropathy, you invited rookie why."

A guy with ID called "little Manyao" mixed into the camp. It was bronze dish B that made them miserable that day.

"Long live, God, you are finally on line."

"God, you are black."

"Today, the little girl knelt down for three sets, and then fell off."

"The great God takes me up, the sub takes me to fly, others open the video with you."

The three animals don't want to pay attention to her. Even Zhao Baliang, who lacks love, disdains to talk to her. Nowadays, there are too many demons on the Internet. It's disgusting to think of a tough guy across the screen.

Qin Ze playfully returned a sentence: "naked (harmonious) chat?"

"I hate it!"

When the screen goes dark, enter the game.
