Qin Ze looked in from the door, this classroom was no different from an ordinary classroom, except that the desks and chairs were all cleared to the back of the classroom, leaving only four or five desks with notebooks, and the students in front of the desks were either looking up or doing their own things without distraction. Professor Li is in his fifties, with gray temples, figure-eight eyebrows, and a pair of rustic round-framed glasses.

He looked away from his computer and turned his head to look, "Come in." ”

Qin Ze nodded and walked to the podium.

Professor Li lifted the frame of the mirror and looked at Qin Ze: "I'm a junior this year, and it's time for an internship in the second half of next year." ”

"Yes, so I want to train myself in advance. After Qin Ze finished speaking, he suddenly found that he didn't have a trace of nervousness, according to his previous urine nature, under the sharp gaze of the professor, not to mention that his legs were trembling, he should always be a little restrained, but he was very calm in his heart, and he was even surprised by himself.

Professor Li nodded, "Although your father has greeted me, we will talk about things and there should be no less assessments." ”

He took out a stack of A4 paper from the drawer, listed many topics on it, picked out a few, and handed it to Qin Ze: "This is a small part of the topics in this digital model, it is relatively simple, you take it and take a look, I will give you two hours, you can pick two questions at will, and calculate the analytical equations." Xiao Liu, give him a pen. ”

The schoolgirl who opened the door immediately handed over a pen.

Qin Ze didn't talk nonsense, looked around, and found that there were no extra seats, so he went to the back row of the classroom and moved a desk out on his own, lightly, trying not to make too much noise.

Qin Ze pounced on the scratch paper to calculate the equation, sometimes looking at the content of the topic, and several times saw that he had to deduce the complete equation, and had to reverse it and start over.

Digital modeling is a very profound knowledge, and what he is doing now is not even digital modeling, it is just a small step in the 25,000-mile long march. Digital modeling, also known as mathematical modeling, is essentially an important means to use mathematical tools to solve practical problems. For example, if a mathematician wants to predict the weather, he can collect data and build a huge digital model that can be used to calculate tomorrow's weather.

Of course, this is just a metaphor, and the real weather prediction is far more complicated than that. But in fact, the Bureau of Meteorology is a huge mathematical model.

Economics and mathematics are inseparable, and numeracy is also a very high and wide application.

Qin Ze calculated for half an hour, his forehead gradually sweated, and he finally felt the right direction. Or is the mathematical foundation too shallow, and many formulas have to rack their brains to remember. If Qin Baobao was here, he would definitely snort twice, push it on Qin Ze's head and say, "You give the old lady a dead door, and you can do it in minutes." ”

It is said that men are naturally logical, and women are naturally sensual, so men are strong in science and women are good in liberal arts. But this law is completely reversed on the Qin family sisters and brothers, Qin Baobao has been top-notch in mathematics since he was a child, and his grades have never fallen out of the top three, and he calls himself the queen of science. Qin Ze is better at liberal arts, and his most brilliant deed is that he won the third prize in the National Middle School Student Essay Contest that year.

Fortunately, he knew that he was not a smart person, he could make up for his clumsiness with diligence, and he did not give up on himself, so he was not stumped by two questions that could block 50% of the students of finance and economics.

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

Two hours later, Professor Li seemed to remember Qin Zelai, stepped down from the podium, came to his desk, did not speak, picked up his scroll and read, the answer to the equation was written on the white paper, the handwriting was neat, and there was a meticulousness that Professor Li liked at a glance. Looking at the scratch paper again, scribbling and altering, the dense calculation formula is not the slightest blank. Qin Ze's mathematics was trained by the old man.

"It's okay!" Professor Li nodded, put the paper back on the table, turned and walked back to the podium, "stop what you're doing." ”

Five or six assistants looked up.

"I would like to introduce you to a new member, Class 7 of the Department of Finance, Qin Ze, your junior. ”

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

Scarce applause.

Professor Li said, "Yang Chen, in the past few days, you should take your junior brother first, and let him figure out our project this morning." I'll have classes later, so I'll go first. ”

A boy in a blue T-shirt and light white slacks nodded, smiling all over his face: "Got it, Professor." ”

Professor Li left.

Before coming here, the old man had already told Qin Ze in detail that it was impossible for Professor Li to do everything with a huge mathematical model, so he needed an assistant, and the assistant's salary was two hundred a day, a week's time. Once the mathematical model is complete, he can get one thousand four.

Professor Li was originally reluctant to recruit students at the school, and several of his assistants were all fourth-year interns who would graduate next month. For the sake of the old man's face, he agreed to let Qin Ze try it.

Qin Ze waited in his seat for a while, and when he saw that the senior named Yang Chen was immersed in work, he took the initiative to walk over and called "senior".

Yang Chen glanced at him, took out a stack of materials from the drawer, and said nonchalantly: "You can take a look for yourself first." ”

Qin Ze had no choice but to take the materials back to his seat and gnaw patiently. A good private equity firm should have its own professional market analysts, which shows that the scale of the private equity firm entrusted to Professor Li is not large. To build a complete digital model, a large amount of formulas and data are required. Mathematics is the most rational thing in the world, and every step needs to be scrutinized. Qin Ze's group is responsible for the rate of return and risk evaluation.

In addition to a not too detailed summary, there is also a series of symbolic explanations. Qin Ze looked a little struggling, took out his mobile phone, searched the Internet, and translated them one by one.

In the blink of an eye, it was time for dinner, and the seniors in the classroom went to the cafeteria to solve the problem of food and clothing. Qin Ze wanted to take out the strength of his head to study hard, but he was kicked out to eat by the senior sister who was in charge of the key.

Because of the limited time, he had a casual meal and hurried back to the classroom.

The door of the classroom was hidden, revealing a crack, and just as he was about to push the door in, he heard someone talking inside: "Brother Chen, what is the new road?" We have worked hard to build this model for a month, and it will be more than a week before the delivery time, good guy, he inserted it coldly and earned our labor costs." ”

The guy who spoke was 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, and they are related to each other, so come over and have a long look at it and mix it with pocket money." ”

"Our group only has a bonus of 10,000 yuan, and he has divided more than 1,000 yuan, grandma's, enough for half a month's rent. ”

"Aren't you still living in your dorm? ”

"Then you can also come to the big health care twice. ”

"Don't worry, there is a task today, he hasn't even figured out the basic situation, and when the time comes, I will assign some topics to him, and he won't be able to complete it, hehe, Professor Li will definitely not like it." A few more times, maybe you'll kick him out. ”

Qin Ze's face darkened, and he said in his heart these two little red guys. He silently went downstairs, walked around the teaching building, and sighed in his heart, sure enough, where there are people, there are rivers and lakes, this kind of fighting without swords and swords is more and more cruel after going to college. No, life is full of fights, and elementary and middle schools are no exception, but at that time, I was young and liked to show it in a violent way.

Qin Ze didn't like this kind of intrigue hidden in the shadows, and he hadn't gotten used to it yet.

Ten minutes later, he went upstairs into the classroom, and the seniors were basically back. The senior sister named "Xiao Liu" smiled at him, and Qin Ze politely smiled back.

There was a professional class at half past one in the afternoon, and after class, Qin Ze refused his roommate's invitation to open the black online, and plunged into the pile of modeling data. Although he is not a talented science expert like Qin Baobao, he has one advantage that the old man praises: he has calm in every major event! This is the old man's own words to praise him.

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

"How are the contents of the information in the area of return and risk assessment?"

"A person is blind and has not yet eaten thoroughly. Qin Ze said.

Professor Li frowned suddenly, and looked at Yang Chen: "Didn't you let him take you." ”

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

Nima, when did you say that.

Professor Li glanced at Qin Ze and didn't say anything, announcing the end of today's work, Professor Li's indifferent attitude made Yang Chen a little disappointed. Only Qin Ze could vaguely guess his thoughts, in fact, the modeling was nearing the end, and the lack of assistants was real, but how could he invite a half-witted man like Qin Ze to join the gang, mostly for the sake of the old man. That day, the old man also said vaguely: If there is anything you don't understand, ask him.

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

Qin Ze asked Yang Chen for information, but he didn't refuse, handed him a stack of copies, a college student, just looking at the information, can you see that the flowers are not successful?

It was still early after the gang broke up, and he spoke in the chat group: "Liberated!"

After a while, Li Liang replied: "Come on, come on, we need you to preside over the overall situation, damn it, you can't take them." ”

Zhao Baliang replied: "I can't take you with me, my brother is one enemy and three, and he will not retreat, and when he turns around, Nima, what about his teammates? ”

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

The corners of Qin Ze's mouth were hooked, the mobile phone was put back in his pocket, and he trotted towards the Internet café with a shoulder bag on his back.

Familiar location, familiar three livestock. With a cigarette in his mouth, he leaned on the sofa chair, because he was waiting for Qin Ze, Li Liang took the time to watch the game video, and Zhao Baliang opened the small window to observe the island country****** Liu Ziqiang played with his mobile phone.

Qin Ze habitually put on a cigarette, turned on the machine, squinted and swallowed the clouds.

"It's summer vacation at the end of the month, what do you say you're tossing. Be careful. Li Liang took a hard puff on his cigarette.

"To earn some pocket money, you can't always let my sister raise it. Qin Ze took out mineral water from his bag and gave each person a bottle.

"Investment modeling is not good, there are too many factors to consider, how did you feel on the first day?" Liu Ziqiang, who had the best results compared to the other two, unscrewed the lid and took a sip, and asked with a smile.

"It doesn't matter if it's hard or not, it's just that I met a slut today and I'm not in a good mood. Qin Ze complained.

"You have a story, but I don't have alcohol. Tell me about it?" Li Liang invited Qin Ze to join the game on the computer by the way.

"It's just an idiot, I'll look for a chance to get him. Qin Ze pouted.

"When the time comes, you must bring eight taels and poke that stupid chrysanthemum with his human cannon. As soon as Li Liang finished speaking, he suddenly made a fuss and shouted: "Neurotic, why are you inviting a rookie." ”

A guy with the ID "Little Waist" mixed into the camp, and it was Bronze Dish B who made them miserable that day.

Xiao Manwaist spoke enthusiastically in the room: "Long live long live, great god, you are finally online." ”

"Great God, you are black. ”

"The little woman knelt three times in a row today, and then fell again. ”

"The great god took me to the top and took me to fly, and people will open a video with you. ”

The three animals didn't want to take care of her, and even Zhao Baliang, who lacked love, didn't bother to talk to her, these days, there are too many shemales on the Internet. The thought of a rough guy across the screen makes Titus disgusting.

Qin Ze playfully replied: "Naked (harmonious) chat?"

"I hate it!"

As soon as the screen goes dark, enter the game.
