I just want to be a quiet scholar

Chapter 15 Boss, please drink tea
After school in the afternoon, Shen Qi came to a small classroom in the laboratory building with a plastic bag of drinks.

Counting Shen Qi, there are twelve students gathered in the classroom. They are the 12 students with the strongest mathematics ability in Nangang No. [-] Middle School. They come from different grades and classes. There are no girls, all of them are boys.

They are the mathematics competition team of Nangang No. [-] Middle School and Senior High School, representing the top mathematics level of the school.

It is not easy to be selected into this team. Those who have not scored full marks in mathematics are automatically disqualified from joining the team.

There are 28 science classes in the first year, second year and third year of senior high school. He is the only one in Shen Qi's second year (2) class who was selected for the school's mathematics competition team. Zhang Wanbang gave Shen Qi a recommendation.

"Boss, please have some tea."

"Boss, please have some tea."

Shen Qi took out iced black tea, iced green tea, and lemon tea from the plastic bag, and handed tea to the other eleven team members one by one.

Shen Qi's father taught him that in the early days of integrating into a new environment, no matter how awesome you are, you have to keep a low profile, observe the situation secretly, and then start to show your strength.

In fact, Shen Qi knew that there was such a mysterious team in the school. Their assembly place was sometimes in the laboratory building, sometimes in the library, and they had no fixed place and no trace.

This morning, Zhang Wanbang informed Shen Qi to report to the small classroom of the laboratory building after school to prepare for this weekend's high school math league.

This is the first time that Shen Qi has joined forces with the school's math competition team. As a newcomer, he first handed tea and observed it secretly.

"How many years and how many shifts?" A fat man asked, taking Shen Qi's iced tea.

Shen Qi replied, "Second year (2) class, Shen Qi."

"Oh, Shen Qi, from the second year of high school." Fatty looked at the other students and asked them, "You are both from the second year of high school, are you familiar with Shen Qi?"

"Unfamiliar." Several boys in the second year of high school shook their heads.

None of the people present here have taken the math exam with full marks. Shen Qi, who has risen to prominence in the past two months, used to be a scumbag, and it is normal for people not to know him well.

Shen Qi kept an embarrassed but polite smile: "I'm a newbie, I would like to ask all of you to take care of me."

"Sit down, Shen Qi." Fatty asked Shen Qi to find a place to sit down, and then introduced himself: "My name is Meng Tianqiang, I'm the captain of the third grade (5) class, and you are welcome to join, Shen Qi."

"Boss, please drink another bottle of tea." Shen Qi took out a bottle of oolong tea from the bag and handed it to Meng Tianqiang.

"Don't drink, stop drinking, lose weight." Meng Tianqiang waved his hand and didn't answer.

Shen Qi unscrewed the oolong tea bottle cap and drank it by himself.

This team gave Shen Qi the feeling that everyone did not reject him, nor did they show any special enthusiasm.

Let's observe and observe.

Since it is a competitive team, there must be a coach.

Shen Qi found that the rest of his teammates were reading books and doing problems by themselves. Half an hour had passed, and the coach had not yet appeared.

Could it be that the training method of this math competition team is to focus on self-study?

Shen Qi didn't dare to ask any more questions, and continued to observe secretly.

When it was close to 7 o'clock, a person came into the small classroom. It was a small old man, thin and a little hunchbacked.

"Hello Teacher Cao!"

"Hello Teacher Cao!"

Meng Tianqiang and others greeted the little old man one after another.

"Hello, Mr. Cao!" Shen Qi greeted him. He didn't know the little old man, so it would not be wrong to call Mr. Cao after him.

Although Cao Xinan was old, his eyes were sharp. He glanced at Shen Qi: "New here? Recommended by Xiao Zhang?"

"Well, my name is Shen Qi. I'm a sophomore in high school. Teacher Cao please give me some advice." Shen Qi guessed that this old man Cao was probably the coach of the team, and the little Zhang he was talking about should be Zhang Wanbang.

"Mathematics relies on talent and comprehension, and advice is a piece of shit." Cao Xinan said lukewarmly.

Shen Qi stopped talking. Why does this old man Cao have the same coaching style as Zhang Wanbang? Zhang Wanbang was brought out by old man Cao?

There is a small blackboard in front of the classroom. Cao Xinan walked to the blackboard and picked up the chalk to write the next question:
"It is known that a is the only real root of f(x)=0, and a>0, please prove that f(x) is divisible by (xa); if a is an imaginary root, please prove that f(x) can be divided by ( x+a) is divisible."

After writing the topic, Cao Xinan said to Shen Qi: "New classmate, I will give you 10 minutes to write the certification process. I am smoking two cigarettes outside the classroom. If you have not completed the certification when I come in, please Where did you come from and where did you go." Then he left and went to smoke outside the classroom.

There are tests everywhere in life, Mr. Cao is testing his math level.Shen Qi stood up, ready to solve the problem.

"Shen Qi, we all went through this kind of test when we first joined the team. Those who are not strong will be eliminated." Meng Tianqiang said with the attitude of someone who had come over.

"I understand, thank you Captain Meng for reminding me." Shen Qi walked to the small blackboard, picked up the chalk but didn't answer immediately, he fell into deep thought.

It is right to fall into contemplation. Of course, Mr. Cao's questions are difficult.Meng Tianqiang stared at Shen Qi's back, this new little junior brother, you are a good and clever person, but unfortunately you don't have hard power.

"This question is too simple, and our school's math team is at this level?" Shen Qi said silently in his heart, it shouldn't, it can't, if Xiao Zhang (Zhang Wanbang) was brought out by old man Cao, the two of them would be better off. The style of the test will not be so low, right?I want to train Chen Xiaoting for a period of time, and she can solve the problem within 10 minutes.

trap.

This must be a trap.

There are traps everywhere in life.

The rivers and lakes are sinister.

5 minutes passed, Shen Qi did not write a mathematical symbol, he stood in front of the blackboard in a daze.

Several high school sophomores in the seats whispered, "Is he from class 2?"

"The overall mathematics level of Class 2 is average, which is a little better than that of Class 3. Class 2 and Class 3 are taught by Mr. Zhang Wanbang Zhang."

"The top is not considered top-notch. Huang Zikun is the best mathematician in his class, but he can't make it into the school team."

"This Shen Qi should have appeared in Class 2 recently. I seem to have a little impression. He got a perfect score in mathematics last mid-term exam?"

"Which of us is not a perfect score in mathematics?"

The rest of the team stopped the books and exercise books in their hands and gathered around to watch Shen Qi. Their suspicions of Shen Qi were deepening. How did this guy sneak into the team?

At this moment, Shen Qi suddenly wrote quickly, brushing, chalk dancing between his fingers, mathematical symbols beating dexterously, and forming an offensive lineup according to a certain pattern, launching a fierce attack on the hypothesis on the blackboard.

This question from Cao Xinan is related to number theory.

Number theory is one of the branches of pure mathematics, which can be traced back to the Diophantine equations in ancient Greece.

The most famous work of Greek mathematician Diophantus is "Arithmetic". Fermat, the "king of amateur mathematics", wrote a hypothesis in the margin of the book when he studied "Arithmetic" and explained it in words: "This hypothesis must be If it is established, I can write the proof process, but there are too few blank spaces in the book to write it down.”

This is the origin of the famous "Fermat's Last Theorem" in the history of mathematics. It was not until 1995 that Fermat's Last Theorem was proved by the British mathematician Wiles.

Qin Jiushao, one of the four major mathematicians in the Song Dynasty in my country, also had a deep research on number theory. The "Nineshao Algorithm" recorded in high school mathematics textbooks came from Qin Jiushao.

The mathematician who is recognized as the most important contributor to number theory is Fermat.

Shen Qi was solving the problem in Fermat's way, which was the main reason why he didn't write for five minutes.

Among the three great gods, Diophantus, Qin Jiushao, and Fermat, Shen Qi finally chose Fermat.

Before Cao Xinan entered the classroom, Shen Qi completed the proof, then returned to his seat and sat down.

"To decompose x^2-1 into two linear factors, let
x^2-1=(x+a)(xa)
Multiply out the term to the right of the equal sign
Then make the coefficients of the same power terms on both sides of the equal sign equal..."

The rest of the math team stared at the small blackboard with a demented look on their faces, speechless for a long time, what is this newcomer writing, I can't understand!
Captain Meng Tianqiang is a senior in high school. After all, he has a lot of knowledge. He was the first to understand Shen Qi's proof idea: "So Shen Qi, you did not use the Jiu Shao algorithm to prove, but introduced a new proof method to simplify the complexity. The proof process is refreshing to me, and the finishing touch is that the coefficients of the transformation and the power term are equal."

Shen Qi explained: "It is not too new. This kind of proof method already existed in France in the mid-17th century, and the Jiushao algorithm appeared in the Southern Song Dynasty in the 13th century. In fact, Qin Jiushao was involved in the study of number theory earlier than Fermat. It has been 400 years. Perhaps Fermat has read Qin Jiushao's "Nine Chapters of Mathematics". From the perspective of mathematics itself, Fermat's theory is more incisive, and of course, standing on the shoulders of giants, he can see farther."

"Hey, that's amazing, Shen Qi, you have already taught Fermat's number theory by yourself." Meng Tianqiang looked at Shen Qi instantly, and he said to the second-year high school students, "Hey, you are all second-year high school students, are you really unfamiliar?"

"Once it's born again, it's cooked twice!"

"It's not familiar now."

"Class 2 has produced talents since ancient times. Shen Qi can do it, but he is a late bloomer."

"Shen Qi, after you joined our team, there are exactly 12 of us, and all the golden saints are in place!"

"Shen Qi, what's your zodiac sign?"

A few high school boys immediately became acquainted with Shen Qi, like long-lost brothers.

"Brothers, let's play together in the future." Shen Qi's secret observation has reached a preliminary conclusion, Meng Tianqiang's mathematics level is higher in this group of people in the classroom, and the other ten people have at most level 2 mathematics level. If you can give them to them rating.

"What's the noise!"

Suddenly, with a loud shout, Cao Xinan returned to the classroom.

The people were quiet and did not speak.

Cao Xinan came to the small blackboard, just glanced at it briefly, and already made a decision in his heart.

With no change in his expression, Cao Xinan looked at Shen Qi and asked, "How long have you been in college?"

Shen Qi thought about it for a while and said, "I read a lot of books. If I had to compare, I would have learned from sophomore, junior and senior years."

dong dong.

Cao Xin'an tapped on the blackboard: "Shen Qi, self-study in college is amazing? You remember it for me, during the main competition of the mathematics league, methods beyond the knowledge of high school textbooks are not allowed, which is equivalent to cheating. What's wrong. Habit, Zhang Wanbang taught you?"

"No, no, I created it myself, I created it myself." Shen Qi definitely couldn't let Zhang Wanbang, his mentor, take the blame.

"I think you're right, change it for me!" Cao Xin'an roared, and then left the classroom with his hands behind his back.

Shen Qi looked confused, Cao Xinan didn't comment a single word on his proof, he just scolded him and left, more condescending than Zhang Wanbang.Are all math teachers like this?

"Have I passed or failed Mr. Cao's test? Should I go home or stay?" Shen Qi asked Meng Tianqiang.

Meng Tianqiang said with a smile: "Of course I stay. Teacher Cao has said that when you are asked to participate in the main competition of the mathematics league, you must not use your university knowledge to solve problems. Congratulations to Shen Qi, I would like to represent the strongest mathematics team of Nangang No. [-] Middle School. My warmest welcome to you! Come, come, applause!"

clap clap.

There was warm applause in the classroom, and all the team members officially accepted Shen Qi.

"Boss, please drink tea." A high school boy wearing glasses handed Shen Qi tea, lemon tea.

"I bought this tea." Shen Qi took the lemon tea.

"Isn't it too late to buy new tea, but the sense of ceremony must come out. Senior Brother Shen Qi, teach me Fermat's number theory when you have time." The high school boy looked humbly asking for advice.
