Metropolis: I Am a Full-Time Professional, Attracting Worldwide Attention

Chapter 116

Chen Xuan ordered a large box with a total of three tables.

There are too many people to sit down at a table.

Anyway, they are all in the same box, and divided into three tables does not affect communication.

Everyone was seated, Chen Xuan began to order food, and the students chatted with each other, and the atmosphere was very harmonious.

After ordering the food, Chen Xuan swept around and did not speak, but silently observed.

Most of this group of students are more cheerful and lively, but some of them are more dull or introverted. The more crowded the occasion, the more nervous they are.

There are a few people who are getting more and more energetic and have a strong desire to express themselves.

But the overall atmosphere is very good. After all, they are all about the same age and have a common language.

The dishes were served quickly. Chen Xuan raised his teacup and stood up and said: “Introduce myself, my name is Chen Xuan, and I will be your counselor for the next month. If you have anything, call me.”

After finishing drinking a cup of Chinese tea, he said, “Everyone also introduce themselves, so I can be seated.”

Speaking and patted a man sitting on the right hand side: “Just you start.”

The boy was a little shy, and when he stood up to talk, his voice trembled a little, obviously he was a little bit shy about this kind of public speech.

“My name is Liang Haoran, I am 19 years old and I come from Dongshan Province.” After a brief introduction, I sat down, blushing like a monkey butt.

Then the next…

A person’s general character can be easily seen from the self-introduction.

He saw someone who liked self-expression, and the introduction was very detailed, just like a blind date.

But most of them are stage fright.

“My name is Han Yu, from Jinling.” The boy stood up and lowered his head to speak, and then sat down with his head lowered when he finished speaking, showing no expression at all.

Chen Xuan paid special attention. This guy is not the kind of stage fright, he just doesn’t want to talk much.

He looks pretty, but the whole person looks a little gloomy.

Everyone introduced themselves, and the students sitting at Chen Xuan’s table said: “Mr. Chen, there are so many of us, can you remember?”

“I must remember. Teacher Chen once read the crime database and remembered all of them. Why are we only 30 people?”

Chen Xuan smiled and nodded: “Remember.”

Let alone the names, these people have their names, gender, personality, contact information, and looks all imprinted in his mind.

This meal has been eaten until more than 8 o’clock in the evening, and the dishes at each table are eaten seven or eighty-eight. The chefs of this restaurant are really good at craftsmanship.

“Let’s go.”

Chen Xuan got up and walked out. They came to the lobby, and a student said, “Mr. Chen, otherwise we can answer a question and we can get a discount.”

Chen Xuan glanced at the wooden sign, then at the cash register, and found that there were quite a few people answering the questions.

“Good idea.” Chen Xuan said: “Go, go and answer the questions, try to get free!”

“There is no hope for free bills, but a 30% and 20% discount is definitely not a problem.”

A group of students are also interested. They are all from the Department of Mathematics, and ordinary math problems are nothing to them.

All subjects are in public, but mathematics has extremely high demands on talents.

It can be said that whether a person can take the path of mathematics has been decided from birth.

“Is this to answer the question?”

“The scumbag shivered.”

“Brother Chen is probably shivering too.”

“Hahaha, it’s true, who made me Chen Ge a 28th student in liberal arts.”

“It’s okay, what happened to the liberal arts student? Does he care about a group of science monks?”

Netizens love to hear.

Chen Xuan and his group walked to the checkout counter and said, “Hello, we want to answer questions.”

Cashiers are also accustomed to this situation, but the other party is Chen Xuan, and her smile is still very sweet: “Brother Chen, what difficulty do you want to choose?”

“Twenty percent off!” a student said.

Chen Xuan asked: “Can you answer more questions? For example, if they answered 20% off, I answered 30% off, or 40% off?”

The cashier said: “Of course you can, no matter how many times you answer it, it will always be the most difficult question you answer.”

This rule is very humane.

Chen Xuan turned around and asked, “Who wants to try?”

“I’m coming!” The student who spoke was called Gao Shu, a very sunny young man.

Gao Shu said: “I choose the 20% off topic.”

Immediately a waiter came over, beside a white board with wheels: “Are you ready?”

“Okay!” Gao Shu was eager to try.

The waiter picked up a notebook and another marker, and quickly wrote a math problem on the whiteboard.

Netizens also stared at the question board seriously, although most people may not be able to understand it.

Question: Given that the complete set U={-1,0,1,2,3}, the set A={0,1,2}, B={-1,0,1}, then (C,A)∩B =?

After writing the question, the waiter said: “You have two minutes to answer the question.”

“Two minutes?” Gao Shu said, “Isn’t there no time limit?”

The waiter reluctantly said: “There are too many people answering the question. It must be restricted, otherwise our shop won’t be open anymore.”

“Are you ready? Ready, I have to time it.”

Gao Shu glanced at the question and nodded: “Time it.”

Then grabbed the pen and started to solve the problem.

Other students quickly calculated in their hearts, and Chen Xuan was also calculating.

This topic is not difficult, and the level is probably equivalent to about the third year of high school.

Just when Chen Xuan was about to calculate the result, a voice suddenly rang in his mind.

“[Xueba’s Blessing] is triggered, congratulations to the host for obtaining [God-Level Quick Calculation]”[God-level speed calculation]: You have the ability to speed calculations across the ages, and your brain is like a supercomputer. No matter how complicated the formula, you can complete the most perfect calculation in your mind!

Chen Xuan’s heart is shocked, this ability is simply against the sky.

Quick calculation is also called mental calculation. There were many programs in the past that included quick calculation.

Let some mathematics geniuses, or those who are clear about numbers, calculate some five or six digit addition, subtraction and multiplier operations.

But instead of using pen and paper, the results are given directly by mental arithmetic, and there is a time limit.

In the past, Chen Xuan always thought this was a lie, but later he discovered that there are really people in the world who can do this.

Just relying on mental arithmetic, you can instantly calculate some results that require a calculator.

When he looked at the question on the whiteboard again, almost instantly, he had the answer in his mind.

All the calculation processes and formulas of the problem were perfectly calculated in his mind within this second.

This kind of speed is beyond the reach of ordinary people and dare not imagine it.

“-1!” Chen Xuan subconsciously said the answer.

And just after he said the answer, about twenty seconds, Gao Shu also completed the problem-solving process, and calculated the final result–1!

Gao Shu almost didn’t encounter any trouble solving the problem, and the whole process went smoothly.

For students in his mathematics department, this kind of topic is simply pediatrics, not worth mentioning.

“What’s the matter, I don’t even understand this topic.”

“Me too. I can recognize them separately, but they won’t work if they are put together.”

“Did Brother Chen just say the answer?”

“I heard it too, and I said it.”

“I watched the replay specially and really said it. Although the sound is very small, it is still quite clear.”

“Brother Chen still knows mathematics?”

“This topic is not difficult, it is high school level.”

“The problem is not difficult, but Brother Chen does mental arithmetic. In the case of mental arithmetic, it is faster than the student’s paper and pen calculations, which shows that Chen is not weak in mathematics.”

Gao Shu put down the pen and said, “It’s done.”

The waiter got the answer right and nodded: “The answer is right.”

Asked again: “Will you continue to answer more difficult questions?”

“answer!”

Other students are also excited.

Anyway, the final answer is the most difficult question.

What’s more, all of them are from the Department of Mathematics.

“Dad is amazing!” At this moment, a girl’s voice sounded not far away.

“I’m going, is this uncle hanging so much?”

“Looking at ordinary, he turned out to be a math god!”

“This is a tri-fold problem, right? Uncle is a strong group!”

Many guests gathered around and let out a cry of exclamation.

Chen Xuan and his group saw that it was a forty-year-old man with a head, wearing a very ordinary striped shirt, wearing a pair of rimless glasses, short hair and flat head, and he had the unique temperament of an academician.

“Then the uncle did a three-fold discount?” Gao Shu blinked, “So strong?”

“It’s him!” said a female classmate: “He is the youngest professor of mathematics at Jiaotong University, Ge Yongqi!”

“Professor Ge?”

“Well, Ge Dashen came here to eat too.”

“The little girl next to me is so cute, is it Professor Ge’s daughter?”

“Nonsense, people call Dad, isn’t it a daughter?”

After recognizing the identity of this man, a group of students suddenly showed admiration.

Those who study mathematics have almost faith-like worship for the predecessors in this field.

In particular, such as Ge Yongqi, the talent is directly at the top, and casual learning is a genius that ordinary students can’t reach the height for a few lifetimes.

This kind of genius has a crushing effect on ordinary students in terms of talent, which is simply desperate.

However, the stronger they are, the more mathematics students will worship, and I hope they can become such a person one day.

After the introduction of these students, Chen Xuan also cast a curious look.

The youngest professor of mathematics at Jiaotong University?

“Are you going to continue to answer the questions?” The waiter’s voice pulled them back.

“answer!”

“How much discount did you answer this time?”

“30% off, step by step.”

“Then I wrote the question.”

The waiter began to write questions, and the students’ attention returned to the whiteboard.

Netizens are attracted by their words and want to see Ge Yongqi.

“Your sister, it has lifted people’s appetite.”

“I checked, it was hired by Jiaotong University at a high price. It is a good man. It is said that he almost proved Fermat’s Last Theorem!”

“Damn, so awesome?”

“Sure Niu Break, or else you can become the youngest professor of mathematics at Jiaotong University?”

“Oh, I don’t want to watch this group of students solve problems, I want to watch Professor Ge pretend now!”

“People are solving problems, not pretending to be force.”

“It’s all the same. Anyway, those who are better than me are pretending to be forced.”

Gao Shu and his team have easily solved the 30% off problem, and are now moving towards the 40% off problem.

And Ge Yongqi over there has already begun to solve the problem of two folds.

He looked relaxed, with a smile on his face, and even touched his daughter’s cute head from time to time.

“Finish!”

Gao Shu has already solved the 50% off problem, and he is a little excited, but the 50% off problem has begun to make him feel a little difficult.

Almost everyone in their mathematics department knows this shop, and occasionally people come here to eat and solve problems.

According to them, some people have solved the four-fold problem.

It’s not that the problem before the four-fold can’t be solved. I really want to solve it. The group of geniuses in the Mathematics Department of Mordu University will definitely be able to solve it.

It is to say that the questions with more than 40% off can already keep some mathematics students out of the door.

Of course, if there is no time limit as before, most students can solve it.

But that kind of doesn’t make much sense.

Chen Xuan watched from the side and nodded secretly.

You know, these are all freshmen.

And the question of the 50% discount just now is not simple, but it was solved within the specified time, which shows that they have a solid foundation in high school.

“Answered!”

“You can answer this question too? Isn’t it too easy to answer this question?”

“Your sister, I have answered all the two-fold questions, god!”

There was another exclamation over there.

“Dad is amazing!” The little girl has two tiger teeth when she smiles, which is very cute.

Ge Yongqi smiled and looked at the waiter, who had already worshipped the five-body cast.

Although he could not understand at all, it did not prevent him from worshiping.

“Teacher, do you still need to continue answering questions?” the waiter asked.

“Yeah.” Ge Yongqi said: “I heard that the title of Yizhe was made by Teacher Lin, and I would like to see it too.”

Lin Cheng is over half a hundred years old, and regardless of his age or his contribution to mathematics, he is his predecessor.

Ge Yongqi respected Lin Cheng very much.

The waiter said: “Teacher wait a minute.”

He ran to the cash register, took a new notebook, and said, “Teacher, there are two choices for this question.”

“What choice?”

Ge Yongqi was a little curious, why did he ask for it before the question came out?

The waiter said: “Professor Lin said that because it is to be reserved for us as a free sheet, it must be solved within an hour. If it cannot be solved within an hour, one more question must be added. ”

“You show me the problem.” Ge Yongqi nodded. Since Lin Cheng said so, it means that this problem can be solved within an hour.

The waiter grabbed the pen and quickly wrote the question on the whiteboard.

After reading the title, Ge Yongqi said softly: “One hour?”

“Yes, one hour.”

“This question…one hour should be no problem.” Ge Yongqi nodded, then looked at his watch, it was almost nine o’clock.

If the problem is solved, it will take at least ten o’clock, the daughter will have to go to school tomorrow, and the wife will have to go to work.

After thinking for a while, Ge Yongqi said: “I can solve this problem, but I don’t have time now, can I take it down? I still pay for the meal at a two-discount price. I just like this topic purely and wait for me to go back. Solve it at home later.”

The waiter said: “Of course it can be photographed.”

Although I don’t know who this teacher is, he must be a scholar who can solve so many problems.

Ge Yongqi photographed the title: “Thank you.”

After paying for the meal, he left with his daughter and wife.

Before leaving, I saw many people watching Chen Xuan and smiled: “The atmosphere here is really good.”

“Husband, that seems to be Brother Chen.” The wife said.

Ge Yongqi said softly: “Really.”

Although he is an academic, he occasionally watches the show, especially like Chen Xuan.

He feels that Chen Xuan is completely different from other reality show stars.

He has real abilities and never makes a show.

Whether you are a cook, a farmer, or a policeman, you have achieved the upper limit that this profession can achieve.

“Go back, don’t disturb him.” Ge Yongqi did not go up to say hello, and left with his wife and daughter.

After they left, Gao Shu also solved the four-fold problem smoothly.

So I continued to solve the three-fold problem, but when it came to this problem, I couldn’t solve it anymore.

The time for the tri-fold question is three minutes, but the difficulty is several times higher.

Gao Shu held the pen and calculated it for a while, but in the end he could only see that the time was up.

“Time is up.” The waiter said.

Gao Shu sighed.

“This question is a bit difficult.”

“Actually, it’s okay, mainly because the time is too short, and it can be solved within ten minutes.”

“The idea is wrong, it shouldn’t be solved like this.”

Among the 30 students, many of them are amazing, but now it doesn’t make much sense to say these.

The waiter asked: “Will you continue to solve it? If you solve it again, you can only start with the two-fold solution.”

Gao Shu shook his head. The other students were eager to try, but they were afraid of being embarrassed if they couldn’t solve it in front of so many people, so no one came forward.

“untie.”

A voice sounded, and everyone saw that it was Chen Xuan.

“Teacher Chen……””I’m quite interested.” Chen Xuan said with a smile: “Write the inscription of the two-fold.”

The waiter said: “The time to solve the problem for two folds is five minutes. If I am sure, I will write the problem.”

“Well, write it.”

The waiter erased the above questions and began to write two-fold questions.

For guests like them, restaurants are welcome.

Most customers can basically solve only a 20% discount or a 10% discount.

And these college students came to solve the problem, and the restaurant was also a propaganda of changing directions, which made the restaurant a little more academic.

Therefore, at this time, they are no longer particularly concerned about the discount, but hope that someone will be able to get through all the way and answer all the questions.

It’s just a pity that the teacher just turned up, and several waiters can see that the teacher has a chance to solve the waived question.

It’s a pity that it’s too late.

“Brother Chen solves the problem?”

“Let me gather, Brother Chen, you are crazy, you are studying literature, what math problems do you solve?”

“This depends on talent, talent is not good, and the hard work acquired is very limited.”

“Brother Chen is not bad, okay, he just figured out a question just now.”

“That question has nothing to say, it’s a high school level question.”

Everyone was surprised that Chen Xuan took the initiative to solve the problem, and the students were also a little surprised.

You know, with his fame and the identity of a teacher, if it is not solved, it will somewhat delay his identity.

Especially in front of a group of mathematics students, and just now there was the youngest mathematics professor of Jiaotong University.

In this way, if Chen Xuan can’t solve it, he will be ridiculed by some people.

However, Chen Xuan did not think about it.

He is currently selecting what he needs from the [Teacher Purchase Channel].

As a gold teacher, the abilities of various subjects have actually reached the top level that ordinary people can reach.

At the current level, these problems can be solved.

However, the biggest gap between ordinary people and geniuses is thinking!

For a problem, ordinary people and geniuses have completely different ideas for solving problems.

Most ordinary people still stick to the formulas and routines left by their predecessors.

The genius does not stick to any form, does what he wants, and can easily deduce the answer.

This is the gap.

If you want to solve it, then solve it in the most perfect state.

“[Mathematician] Successfully purchased”

“Congratulations to the host for obtaining [mathematician]”

[Mathematician]: Five thousand years of experience, the most powerful brain!

Suddenly, Chen Xuan seemed to see a well-known mathematician at home and abroad appear in front of him.

These mathematicians do calculations, research, argumentation, or write a line on the blackboard in front of the blackboard that looks like a celestial book.

Chen Xuan can clearly feel the excitement hidden under the calm faces of these mathematicians.

This is the excitement when we are about to prove some theories!

“Next, you have five minutes to solve the problem.” The waiter wrote the two-fold inscription, and his voice pulled Chen Xuan back to reality.

Chen Xuan’s gaze was fixed, and he fell on the whiteboard’s question, swept across it, and subconsciously replied, “One minute.”

When the words are over, grab the marker and start writing the calculation process and formula on the whiteboard.

“One minute? Brother Chen, this can’t be bragging.”

“Finished, Brother Chen is about to collapse.”

“This question is a bit curious. It takes some time for mathematics majors to answer it. One minute is basically impossible.”

Wu Tongdao: “Chen Xuan also seems to have a very good score in mathematics, but one minute…I think it’s still a bit dangerous.”

“I’m a liberal arts student and I don’t understand mathematics at all.” Jiang Ting smiled bitterly, and looked at a teacher from a college who had just invited today: “Ms. Song, is this problem difficult?”

Teacher Song said, “This question involves the Law of Sines and The Law of Cosines. The difficulty is not low, and it is very complicated.”

“Can it be solved in one minute?”

“I can’t.” Teacher Song didn’t say anything to death. Suddenly, her eyes stared at the screen slightly changed: “He…seems to really be able to solve it.”

Everyone in the live broadcast room looked at Chen Xuan right now, holding a pen on the whiteboard and writing down the deduction formula line by line without chaos.

There is no trace of stagnation, just like Te Mo’s answer, it is extremely smooth.

From the beginning, Gao Shu’s group was skeptical, and now they open their mouths, unbelievable.

The barrage in the live broadcast room also disappeared. Although they could not understand, the derivation process written by Chen Xuan felt unclear.

Teacher Song was full of vigor, and after about forty seconds, he said, “He solved it!”

After speaking, Chen Xuan wrote down the final answer, put the pen down, and then glanced at the cell phone in the waiter’s hand: “How long?”

The waiter pressed his mobile phone, his voice knocked: “43…seconds.”

There was deathly silence in the live broadcast room.

…

…

Ge Yongqi is already taking his wife and daughter on the way back, he is driving, his wife and daughter are sitting in the back seat.

Suddenly, he heard his wife whisper.

“What’s wrong?”

“Husband, how long did it take you to solve the two-fold problem?”

“About three minutes.” Ge Yongqi said: “This question is not difficult, but the process is a bit complicated, and it takes a certain amount of time to write it down. If you change to pen and paper, you can finish it in about two minutes if you change it faster.”

After speaking, Ge Yongqi asked: “Why do you suddenly ask about this?”

The wife was silent for a long time before she said, “Brother Chen spent 43 seconds.”
