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

Chapter 117

43 seconds!

This number made Ge Yongqi slightly startled.

His first reaction was: “Who is Brother Chen?”

“That’s Brother Chen.” The wife seemed to hear the doubt in her husband’s tone, and said: “Chen Xuan, we saw him when we just ate.”

“43 seconds, are you sure?”

“Problems solved live.”

“correct?”

“correct.”

“Go home first, I’ll take a look at it later.” Ge Yongqi didn’t say such things as impossible.

After all, I am doing academic work, and I consider things more rigorously.

And no matter what math problem, there is more than one way to solve the problem.

It takes about two minutes to solve the problem according to his idea. This does not mean that others have to use two minutes.

This side.

Chen Xuan put the pen down, the waiter compared the answers and nodded: “The answer is correct.”

Asked again: “Brother Chen, do you… do you want to continue?”

“Go on.” Chen Xuan smiled and said, “I also want to see how difficult the questions Prof. Lin asked are.”

“Ms. Chen’s math turned out to be so good?”

“Forty seconds, so fast…”

“The idea of solving the problem is so clear, I never thought it could be solved like this.”

The students looked in admiration.

“Damn, I thought he was pretending to be forceful, but I didn’t expect him to be pretending to be forceful!”

“Damn it, let him pretend it!”

“If you don’t understand, just ask, what’s the level of Brother Chen?”

“It’s very strong. If you are placed on the high school math team, you can get three thousand levels in math competitions.”

“So hanging? Isn’t Brother Chen a liberal arts student?”

“It’s probably the math that I learned later.”

Netizens are also amazed.

The waiter said: “There are two ways to answer the one-fold question. One is that you need to solve all the steps within an hour. If you can’t solve it within an hour, you have to add another question.”

Everyone listened attentively, for fear of missing something.

Especially these students at the scene, they know, this question was given by Professor Lin.

Regardless of whether it can be unlocked, but if they have a chance to take a look, they will certainly not miss it.

Chen Xuan asked: “What more questions?”

“A quick calculation question.” The waiter said: “Professor Lin said that his questions require a certain quick calculation foundation. If you have this foundation, you don’t need to be subject to the one-hour limit.”

Chen Xuan thought for a while, nodded and said, “Make quick calculation problems first.”

“Ms. Chen, is this going to challenge high difficulty?”

“I don’t know if it’s a quick calculation of a few digits.”

“The number of digits is not important, the important thing is to add and subtract the multiplier… I’m afraid it is a quick calculation of multiplication and division, it is too difficult.”

The students present suddenly felt a sense of oppression and tension when they returned to the college entrance examination.

Although it is not them who have to answer the question, they are under pressure to empathize.

The waiter said: “Brother Chen, after I tell the question, you have ten seconds to quickly calculate the result. If it exceeds the time, it will be a failure.”

“good.”

“9285?? 2608? 73 = how much?”

The waiter wrote down the question as he spoke, and then started timing.

As soon as this problem came out, everyone felt dizzy in their heads.

“Crazy, do you call this a quick calculation?”

“This is really a quick calculation, but the difficulty is a bit high, just multiply and divide directly.”

“Will Mao be quick to solve a problem?”

“Because of many problems, if you don’t have the basis for quick calculations, you basically don’t want to solve them within the specified time.”The students at the scene felt malice, and this topic is really outrageous.

Although the onlookers do not particularly understand math problems, this kind of multiplication and division can still be understood.

But only when you can understand it can you understand how difficult it is.

There is a computer, which is easy to calculate, but the problem is that you are not given a calculator.

However, almost immediately after the question came out, Chen Xuan’s brain was already turning like a super calculator.

Numbers beating in my mind regularly, and the answer was given the first time.

He grabbed the pen and wrote the result: “.”

The waiter widened his eyes: “Brother Chen, are you sure?”

“Confirm.” Chen Xuan smiled: “Confirm the result.”

“okay.”

This question was also given by the waiter temporarily. According to the requirements, if someone chooses to do quick calculation, he will give the same number of multiplication and division.

He took out his calculator and started to calculate.

Not only him, but many people at the scene also took out their mobile phones to play tricks.

“Fuck, the answer is right”! ”

“Really right…”

“Brother Chen, you are not human!”

“Really? Chen Ge calculated it?”

“This is too great, this kind of quick calculation, how much a big cow can you figure it out?”

“I don’t even have a calculator as fast as Brother Chen reckons.”

“Really… I observed it and Brother Chen calculated that it only took less than two seconds. If the time for him to write is removed, it may only take one second… This is too ridiculous.”

The live broadcast room was slumped and kneeling.

The waiter also figured out the answer: “Is… correct?”

He counted it several times in a row and was sure that the answer was okay.

Moreover, he temporarily used this topic, and there is no possibility of cheating.

“Hiss~”

A group of students took a breath, and Teacher Chen was so terrible!

The waiter stabilized his mind: “I will write down the topic of a discount.”

“good.”

The waiter erased the numbers on the whiteboard and quickly copied the questions.

Question: It is known that the side length of the square ABCD is 1…

“This topic…how it feels weird.”

“I can guess the answer, but I don’t know how to prove it.”

“Me too, the answer has a rough outline, but the argumentation process does not know where to start.”

A group of students frowned and looked at the title on the whiteboard, obviously stumped.

Chen Xuan’s first reaction when he saw the title was that it was difficult and not difficult.

This question needs to examine the focal radius formula and express multiple vectors.

The whole question is actually not difficult, but it is a coincidence that it requires a very, very solid foundation to be able to solve the process.

If you just look at the topic purely, you can give a rough result.

But mathematics questions are not just about giving the results. On the college entrance examination, you only give the results but not the process, and you won’t get high scores.

And this problem-solving process is more time-consuming, because it is very long.

No wonder there is a one-hour limit.

This has to be replaced by the Gaoshu guys, let alone an hour, even if they are given a day, it may not be able to solve it.

Because this question is very misleading, it is easy to be misled by a little carelessness.

Especially, you will find out what went wrong at the end of writing.

So before solving the problem, you must have a clear idea.

Chen Xuan grabbed the pen and began to write on the whiteboard, saying, “Bring two more whiteboards.”

“Ah? Oh.” The waiter immediately pushed the whiteboard over.

The students stared at it earnestly. Judging from the problems that Chen Xuan solved and the quick calculations, he did have a high level of mathematics.

At least, they have a higher standard than their mathematics students.

Chen Xuan wrote very quickly. In less than five minutes, a whiteboard was full.

He continued to write on the second whiteboard.

Everyone looked at the full numbers, with a kind of dazzling feeling.

What are these things?

Why can’t you understand a word?

About twenty minutes later, all three whiteboards have been written.

Chen Xuan felt relieved and said, “Okay.”

The waiter looked at the three whiteboards full of writing, a little lost, he couldn’t understand it.

“Brother Chen, I need to check the answer.”

Chen Xuan glanced at the time and said, “Well, let me pay at a discounted price first. The answer is that you turn around slowly. If there is no problem, when I come to eat next time, you will pay the discounted money. Return it to me.”

It’s getting late, it’s ten o’clock soon.

He doesn’t care, but these students have to go back to rest, it is impossible to spend here all the time.

The waiter thought about it, this is indeed a good way.

The main thing is that they are not professional, and it takes time to find the answer.

So Chen Xuan took the students and left after paying a 10% discount.

“Ms. Song, is the argumentation process and results given by Chen Xuan correct?” Jiang Ting asked.

Several other people came over curiously, and they wanted to know.

Teacher Song said: “The result should be right. I have to go through the process.”

“If the process is right, Chen Xuan’s talent in mathematics is a bit scary.” Xu Chengzhou said with emotion.

…

Ge Yongqi had already returned home. After a brief wash, he went back to the study to calculate the problem that Professor Lin Cheng gave.

As soon as the phone was turned on, a news popped up.

“Student master Chen Xuan, solved Professor Lin’s problem perfectly in only 20 minutes”

Ge Yongqi was a little surprised. He quickly clicked in and found that the top searches on Weibo were all Chen Xuan.

# Chen Xuan One second quick calculation of five-digit multiplication and division#

“one second?”

Ge Yongqi said softly and clicked in one by one to take a closer look.

After reading it, Ge Yongqi was silent.

From Chen Xuan’s solving the two-fold problem, to his quick calculation of the correct answer in one second, and less than 20 minutes to solve the problem of Professor Lin Cheng.

Ge Yongqi felt that he was a mathematical genius.

In terms of talent, I’m afraid it’s better than myself.

Ge Yongqi could understand his problem-solving idea, but he didn’t think of this problem-solving idea for the first time.

If you change him to solve it, it will take about forty minutes.

Chen Xuan doubled this efficiency.

“Such a mathematics genius, turned out to be a liberal arts student?” Ge Yongqi couldn’t help but laugh.

…

Chen Xuan took the students back to school and watched them go back to bed before turning around and walking to the dormitory with rhubarb.

After returning to the dormitory, Chen Xuan went to sleep.

On the Internet, Chen Xuan also has a new title-Xueba!

The next day, Chen Xuan still got up early, his work was monotonous and boring.

He even felt that solving the problem in the hotel last night would probably be his brightest moment in this month.

At noon, an old lady who was over 50 years old and gray-haired came to the courtyard.

She knocked on the courtyard door and shouted, “Is Teacher Chen at home?”

Rhubarb was lying on the ground basking in the sun. Hearing the sound, he turned his head and rushed into the room with a few “barks”.

Chen Xuan searched for her voice, saw the old woman at a glance, walked over to open the door and said, “Auntie is looking for me?”

The old woman smiled and said, “Hello, Teacher Chen, I’m Qian Yanhong, a teacher from Modu University.”

Chen Xuan quickly invited her into the yard: “Teacher Qian, sit down and I will make you a cup of tea.”

When the tea was brewed, Chen Xuan brought it up and asked, “Does Teacher Qian have anything to do with me?”Qian Yanhong said: “There is indeed something I want to trouble you.”

“you say.”

“It’s like that. There will be a class for me tomorrow, but there is something in my house that can’t go away, so I want you to help me take the class.”

“¨” Substitute? “Chen Xuan was quite surprised: “Teacher Qian, take the liberty to ask, what subject do you teach?” ”

“Ancient poetry.” Qian Yanhong said: “I heard that you studied ancient literature in college, so I thought of you. Teacher Chen, is it convenient for you?”

Qian Yanhong’s ancient poetry class is held once every half a month, and the frequency is very low. There are not many people taking it, but she doesn’t care.

She is over 60 years old, and she has reached the age of retirement a long time ago. She was rehired by Magic University.

She is willing to accept the invitation of Magic University to open courses, purely because she loves ancient poetry, and also wants more people to feel the charm of ancient poetry.

But tomorrow she has something and can’t speak normally, so she thought of Chen Xuan.

Looking for Chen Xuan is also selfish.

First, Chen Xuan was born in ancient literature and has a certain foundation.

She will prepare the lecture content in advance for Chen Xuan, he only needs to teach according to his own preparation content.

Not to mention how amazing it is, but it is also quite satisfactory and not too bad.

Secondly, she also hopes that through Chen Xuan’s personal reputation, more people will pay attention to this course.

“I have prepared the content of the lecture in advance. Teacher Chen can read it out as usual tomorrow.” Qian Yanhong said.

Chen Xuan nodded slightly, thought for a while, and said, “No problem.”

Staying in the yard is just waiting. Someone asks him to replace him, at least in recognition of him.

And it also allows him to spend this month as a teacher in such a boring way.

“Thank you, Teacher Chen.” Qian Yanhong breathed a sigh of relief. She handed over the preparation textbook: “Thank you, Teacher Chen, here is the content of tomorrow’s lecture.”

“Okay.” Chen Xuan took it and said with a smile: “It’s the first time I teach a student. If I don’t speak well, I will ask Teacher Qian to bear it.”

Qian Yanhong shook his head: “My elective course is more to make students more interested in ancient poetry. It is far from reaching the point of preaching and receiving a career. Teacher Chen must not have too much pressure. Not to mention it. It is to teach new knowledge, rather than to discuss interests and hobbies together.”

“Brother Chen is really not afraid of anything. It’s not easy to listen to a class like ancient poetry, so I dare to take it.”

“At any rate, I also had a background in ancient literature, and there are also lessons to be prepared, so it’s not a big problem.”

“Because Mao doesn’t have a math teacher to ask him to take the place?”

“Sum (Wang Wanghao) is better. I read the explanations of several big cows, saying that the problem that Chen Ge solved last night is not difficult in nature, but his idea of solving the problem is very novel.”

“Brother Chen is hobbies at most, and there must be a gap between him and the teacher who specializes in teaching mathematics. Ancient literature is more suitable for Brother Chen.”

Qian Yanhong stayed in the small courtyard for a while before leaving.

Chen Xuan opened the preparation textbook and looked at it page by page.

This teacher Qian is very professional and his handwriting is also very beautiful.

The textbook is rich in content and clear in order. Chen Xuan knew the rhythm of the lecture at a glance.

He nodded secretly, as he deserved to be re-employed by Magic University. There are not two brushes that really dare not serve as a teacher here.

After reading the content of the textbook, Chen Xuan closed it, and in his mind he also planned to prepare for the lecture tomorrow.

The first is a sufficient reserve of poetry. There are many poets in this world, but they are still inferior to those on earth.

No matter what type of poem, the overall quality and quantity are far from each other.

In this regard, Chen Xuan is not worried, and only needs to explain the content of the preparation textbook according to the textbook, which is actually enough.

He thought for a while, and finally used a professional card.

“Please specify a profession…”

“The profession has been determined. Congratulations to the host for obtaining [Grandmaster-level Danqing]”

[Grandmaster-level Danqing]: The book is written by the brilliant pen Danqing, and each stroke is a self-contained system!

Chen Xuan picked up a pen casually from the room, and for a moment, he felt that he was not writing words, but building a world!

One word is one world!

This kind of strange feeling gave him a very strange feeling.

Ben just wanted to have a good hand, after all, I still have to write on the blackboard tomorrow.

Unexpectedly, he went directly to the top of calligraphy.

Tomorrow’s lecture, even if the content is general, but with this eye-catching handwriting, it can also add a lot of points.

That’s it!
