Qin Ze looked in from the door. There was no difference between this classroom and an ordinary classroom, except that the desks and chairs were cleared to the back of the classroom, leaving only fourorfive desks with notebooks. The students in front of the desks either looked up or were absorbed in doing their own things. Professor Li is in his fifties, with white temples, eight character eyebrows and a pair of rustic round frame glasses. He looks like a very serious and difficult old scholar.

He looked away from the computer, turned his head and said, "come in."

Qin Ze nodded and walked to the lectern.

Professor Li held 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." Qin Ze said that, he suddenly found that he didn't have a trace of tension. According to his past urination, he was examined by the professor's sharp eyes, and his legs were trembling. He should be a little restrained, but he was very calm in his heart, and even surprised himself.

Professor Li nodded, "although your father said hello to me, let's talk about things as they are. There should be no less examinations."

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

The girl student who opened the door immediately handed over a pen.

Qin Ze didn't talk nonsense. Looking around, he found that there were no extra seats, so he went to the back of the classroom and moved a desk out by himself, with light hands and feet, trying not to make too much noise.

Qin Zepu calculated the equation on the draft paper, and sometimes looked at the content of the subject. Several times, he saw that he had to push down and start over again to calculate the complete equation.

Numerical modeling is a profound knowledge, and what he is doing now is not even numerical modeling, but a small step in the 25000 mile long march. Mathematical modeling, also known as mathematical modeling, is essentially an important means of using mathematical tools to solve practical problems. What's more, it 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 establish a huge mathematical model to predict the weather tomorrow.

Of course, this is just a metaphor. Real weather prediction is far more complicated than this. But in fact, the meteorological bureau is a huge mathematical model.

Economics and mathematics are inseparable, and mathematical modeling is also widely used.

Qin Ze calculated for half an hour, his forehead gradually sweating, and finally felt the right direction. It's still that the foundation of mathematics is too shallow. Many formulas have to be racked up before they can be remembered. If Qin Baobao is here, he must hum twice, push it on Qin Ze's head and say, "you'll get it done in minutes."

It is said that men are naturally logical and women are naturally emotional, so men are strong in science and women are good in liberal arts. But this law is completely reversed on the Qin family's siblings. Qin Baobao has been at the top of mathematics since childhood, and his grades have not fallen out of the top three. He calls himself the queen of science. Qin Zeze's liberal arts is better. His most brilliant story is that he won the third prize in the national composition contest for middle school students that year.

Fortunately, he knew that he was not a smart man, and that he could work hard to make up for his weakness. He did not abandon himself, so he was not baffled by two problems that could stop 50% of college students from getting rich.

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

Two hours later, Professor Li seemed to think of Qin Ze. He walked down the platform and came to his desk without talking. He picked up his paper and looked at it. The answer to the equation was written on the white paper in neat handwriting, which Professor Li liked at a glance. Look at the cursive paper. There is no blank in the dense calculation formula. Qin Ze's mathematics was trained by the old man.

"OK!" Professor Li nodded, put the paper back on the table, turned and walked back to the podium, "stop the work at hand."

Fiveorsix assistants raised their heads.

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

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

Sparse applause.

Professor Li said, "Yang Chen, take your younger martial brother first these days and let him figure out our project this morning. I have classes later. Let's go first."

A boy in a blue T-shirt and light white slacks nodded and smiled, "I see, professor."

Professor Li left.

Before coming here, the old man had told Qin Ze in detail that Professor Li couldn't do everything by himself with a huge mathematical model, so he needed an assistant whose salary was 200 a day for a week. After the mathematical model is completed, he can get fourteen.

Professor Li was originally unwilling to recruit students at school. Several of his assistants are senior interns and will graduate next month. In the face of the old man, he promised to let Qin Ze try.

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

Yang Chen glanced at him, casually took out a pile of information from the drawer, and said, "look at it yourself first."

Qin Ze had to take the information back to his seat and chew it patiently. A good private placement company should have its own professional market analysts. It can be seen that the private placement company entrusted by Professor Li is not large. To build a complete mathematical model requires massive formulas and data. Mathematics is the most rational thing in the world, and every step needs to be reconsidered. Qin Ze's group is responsible for the yield and risk evaluation.

In addition to the not too detailed summary, there are a series of symbols in the material. Qin Ze seemed to be struggling. He took out his mobile phone, searched the Internet and translated one by one.

In the blink of an eye, it was time for dinner. The elder students in the classroom went to the canteen to solve the problem of food and clothing. Qin zeben wanted to take out the energy of hanging his head and stabbing his head, but he was driven out to eat by the schoolsister who was in charge of the key.

Because time was limited, he ate casually and hurried back to the classroom.

The classroom door was ajar, revealing a crack. As soon as I was about to push the door in, I heard someone inside saying, "brother Chen, what's the new way? We have worked hard to build this digital model for a month, and it's more than a week from the delivery time. Good guy, he jumped in cold and earned our labor costs."

The guy talking is also from Qin Ze's group, so I don't know his name.

Yang Chen snorted, "his father and Professor Li seem to be in the same office. They are related households. Come and have a long experience and mix pocket money."

"The bonus of our group is only 10000 yuan. He just distributed more than 1000 yuan. Grandma's is enough for half a month's rent."

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

"Then you can have two major health care."

"Don't worry, there is a task today, and he didn't even know the basic situation. I'll assign some topics to him at that time, and he won't be able to finish it. Hehe, Professor Li must be unhappy. Come a few more times, and maybe he will be kicked out."

Qin Ze's face was black, and his heart said that these two little red guys. He went downstairs silently, strolled around the teaching building, and sighed in his heart that there was indeed Jianghu where there were people. This kind of fighting without swords and swords became more and more cruel after he went to college. No, there are battles everywhere in life, and primary and secondary schools are no exception, but at that time, I was young and liked to show it in a violent way.

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

More than ten minutes later, he went upstairs into the classroom, and the seniors and sisters basically came back. The schoolgirl named "Xiao Liu" smiled at him, and Qin Ze politely replied with a smile.

There was a professional class at 1:30 p.m. after class, Qin Ze refused his roommate's invitation to go online and plunged into the pile of modeling materials. Although he is not a talented science expert like Qin Baobao, he has one advantage that the old man praises endlessly: there is calmness in every major event! This is what the old man praised him personally.

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

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

"A person is unpredictable and hasn't understood it yet." Qin Ze said.

Professor Li frowned and looked at Yang Chen, "didn't you take him with you?"

Yang Chen looked innocent: "I gave him the information and let him ask me casually if he didn't understand it, but he didn't have any problems all day. I thought Qin Ze had a deep foundation and understood it by himself."

Nima, when did you say that.

Professor Li glanced at Qin Ze and didn't say anything. He announced that today's work was over. Professor Li's calm attitude made Yang Chen a little disappointed. Only Qin Ze can vaguely guess his mind. In fact, modeling is nearing the end, and the lack of assistants is true, but how can you invite such a half hearted person as Qin Ze to join the gang? It is mostly for the sake of the old man. The old man also said implicitly that day: ask him if you don't understand anything.

So whether Qin Ze is fooling around or not, Professor Li doesn't care. His father is helping behind the scenes.

Qin Ze asked Yang Chen for the information, but he didn't refuse. He handed him a pile of copies. A college student can see whether the flowers come by looking at the information alone?

It was still early after breaking up. 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, can't take them."

Zhao Ba Liang followed and replied, "I can't take you. I will fight against three with one brother. I will never retreat. When I look back, NIMA, where are my teammates? All my teammates are dead back in the hot spring."

Then there was Liu Ziqiang: "I'll watch you pretend to be forced and don't talk."

Qin Ze picked up the corners of his mouth, put his mobile phone back in his pocket, and trotted towards the Internet cafe with a shoulder bag on his back.

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

Qin Ze habitually takes a cigarette in his mouth, turns on the machine, squints, swallows clouds and exhales smoke.

"It's summer vacation at the end of the month. What do you say you're doing blindly? Be careful to fail." Li Liang took a hard smoke.

"If you earn some pocket money, you can't let your sister keep it all the time." Qin Ze took out mineral water from his bag and gave each one a bottle.

"Investment modeling is not easy to do. There are too many factors to consider. How did you feel on the first day?" Compared with the other two, Liu Ziqiang, who achieved the best results, unscrewed the lid, took a sip, and asked with a smile.

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

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

"It's just a fool. I'll find a chance to get rid of him." Qin Ze pie pie mouth.

"At that time, you must take eight Liang and stab the stupid chrysanthemum with his human cannon." As soon as Li Liang finished speaking, he suddenly made a fuss and shouted, "crazy, why are you inviting a rookie?"

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

Xiao Manyao spoke enthusiastically in the room: "long live, God, you are finally online."

"Great God, you are black."

"The little girl knelt three times in a row today, and fell off again."

"The great God takes me up, divides me, and flies me. People open videos with you."

Three animals are unwilling to talk to her, and even Zhao Ba Liang, who lacks love, disdains to talk to her. There are too many human demons on the Internet these days. It's disgusting to think of a rough man across the screen.

Qin Ze replied thoughtfully, "naked (harmonious) chat?"

"Annoying!"

When the screen goes dark, enter the game.
