Omnipotent Data

The sage ♂ no Mori.

Cheng Nuo: "Has the high math teacher called? @袁华"

Yuan Hua: "No, I'm ready to start the first chapter, I guess I won't click it."

Yuan Hua: "Brother, you won't... prepare to skip class!"

If you skip class in the first class of school, then you are really great!

Cheng Nuo: "What can I do, I am also desperate!!"

Yuan Hua was silent for a while.

Yuan Hua: "Then you didn't attend the class, what about the advanced math course?"

Cheng Nuo: "It's okay. During the summer vacation, I read "Advanced Mathematics" up and down. Basically there is no difficulty, it is all the most basic things. Even if I directly let me take the final exam now, it is not worth it."

Cheng Nuo is right.

In the last two or three days before the end of the summer vacation, Cheng Nuo stayed at home and previewed all the freshman courses in the Department of Finance.

As for the first volume of high maths, Cheng Nuo only took half a day and more to complete the preview.

Then, I searched for the high-numbered test papers at the end of the first term of Tsinghua University last year.

The final score...100 points!

It's easy and no pressure! It was so simple that Cheng Nuo even wondered if what he was doing was elementary school math problems.

At that time, Cheng Nuo wondered, why many people say that high numbers are difficult?

is it hard?

Obviously very simple.

Someone even wrote a poem for him.

"High Numbers and Difficulties"

Author: hard to force students

噫嚱嚱, the danger is high! The difficulty of high numbers is difficult to reach the sky! Functions and limits, what a loss at the beginning! Come here for one hundred and sixty pages, not with the answers. The number sequence function has a limit, two criteria to achieve. The example exercises are dead, and then the final exam is linked. ... Although the university is happy, it is better to return home early. It's difficult to count, it's difficult to go to the blue sky, sideways looking to the west.

However, this is not a problem that Cheng Nuo is struggling with.

Cheng Nuo: "Okay, let's talk about this for now. I think the teacher on the podium is about to give a lecture. When the first get out of class of this big class is over, I will find a chance to sneak back."

Yuan Hua: "Yeah."

Cheng Nuo put away the phone and opened the textbook.

Uh……

Well, this is a high substitute course, what kind of a high mathematics textbook by yourself!

Cheng Nuo scratched his head, tucked the high mathematics textbook back into his school bag, and then took out a draft book.

They come, the security.

Since Cheng Nuo is here, naturally he can't just sit here.

Just by taking this opportunity, Cheng Nuo wanted to feel the learning atmosphere of the Department of Mathematics.

Isn't it Gao Dai?

Although the subject of advanced generation is a professional course of the Department of Mathematics, in the final analysis, it is only a basic course of the Department of Mathematics.

The difficulty is greater than the high number, but it is also not excessive.

Cheng Nuo doesn't think that going to Gaodai is a rare opportunity to live with himself. Even...in the absence of textbooks!

Cheng Nuo glanced roughly at the classroom.

Since the Department of Finance and the Department of Mathematics were trained on the same playground during the military training, Cheng Nuo knew that the number of students in the Department of Mathematics this year was about 30.

I swept it just now. There were 32 people in the entire classroom, except for himself and Teacher Liao on the podium.

30 boys and 2 girls.

A pretty scary male to female ratio.

This made Cheng Nuo pat his chest with joy. Sure enough, I didn't choose the Department of Mathematics at the beginning. It was a wise choice.

However, this male-to-female ratio is no way.

After all, the Department of Mathematics at Tsinghua has been like this over the years. Girls in their mathematics department are like national treasures.

In the classroom, Cheng Nuo also found a familiar figure, Zhao Yang.

The freshman in the mathematics department who was in the military district and Cheng Nuo. He was sitting in the first row at this time, listening carefully to the teacher on the podium.

Let's go...

Teacher Liao, who was standing on the podium, didn't have a long story. Like teachers in other schools, he didn't have the brilliance of blowing one class first in the first class.

Ms. Liao spent five minutes talking about the content of the course, the test method, and the short answer. I didn't say what projects I had participated in, and what awesome students I had brought out.

These things are all imaginary. As teachers at Tsinghua University, they can't finish the list of honors in two lessons.

But they are completely unnecessary.

At that time, it would be better to talk about two more questions.

"Come on, let's take out the textbook and write the first chapter." Teacher Liao said to everyone while opening the ppt courseware.

The first chapter of "Advanced Algebra", polynomials.

The first section, the number field.

The second section, the concept of divisible.

...

Teacher Liao's lecture is very fast.

How fast is it?

In some places, the high-generation teachers on the stage have already finished speaking.

But under the stage, there are still many people who can't find it. Where is this theorem in the textbook?

One by one formulas, theorems, and example questions were instilled into the brains of more than 30 students in the classroom by teachers from Gao Dai.

In each section, the high-generation teacher points out the key points, and then exposes one or two typical sample questions, and continues to the next section.

Under the stage, every student in the Department of Mathematics was waiting like a college entrance examination, looking up and listening, while memorizing something in textbooks or notebooks.

But even so, still only a very small number of people can keep up with the rhythm of Gaodai teachers.

Most of the students looked dumbfounded, staring blankly at the densely packed mathematical symbols on the blackboard.

who am I? where am I? What should i do?

For example, the fat student who is sitting next to Cheng Nuo.

In the first ten minutes, I can keep up with the rhythm of Gao Dai teacher.

But when he accidentally dropped the pen, picked it up with his head down, and then raised his head to continue attending the class.

Suddenly found out crying without tears...

I really can't understand it!

In this short period of four or five seconds, the teacher Gao Dai has already talked about the past two or three key steps.

This……

He looked at a pile of mathematical formulas that seemed clueless to him at this time, completely speechless.

In sharp contrast with most of the people in the class, it was Cheng Nuo.

The other classmates were either looking up to listen to the class carefully, or lowering their heads to take notes in a rush.

Cheng Nuo is different.

Although he has no textbooks and no preview, he has no idea what the first chapter of the advanced textbook is about.

But this did not prevent him from attending the class.

Students in other mathematics departments think that the fast lecture speed is just right for Cheng Nuo.

On the stage, every time Teacher Liao uttered a formula or concept, Cheng Nuo could quickly grasp it.

Cheng Nuo basically glanced at the sample questions and calculated them in his mind. The steps are basically not too different from what the Gaodai teacher said.

As for notes, they don’t exist! It is impossible to take notes, and it is impossible to take notes in this life. I can only rely on the occasional full score to sustain my life.

brain! It is Cheng Nuo's best notebook! If you want to use any knowledge points, you don't need to bother to go through the notes, just call them out of your mind.

Hey! there's no way!

Cheng Nuo sighed. With the halo of Xueba, he is so helpless even if he is so cheating!

Cheng Nuo took advantage of Teacher Liao's teaching effort, drank his mouth water, and simply chatted with Mu Leng for a while. Look up, scan the courseware and the formula on the blackboard roughly to keep up with the progress of the teacher.

It's so beautiful and beautiful!

In the entire classroom, I'm afraid there is only Cheng Nuo alone, so it's so relaxing.

The scariest thing is that Cheng Nuo... is a student of the Department of Finance!

"Advanced Algebra" Chapter 1 Polynomials, a total of eleven sections, fifty or sixty pages!

Liao Zhixing only took less than half an hour to finish the lecture.

Yes, yes, it only took half an hour!

This is the legendary Tsinghua speed!

Rather than finishing the lecture, in the eyes of the students of the Department of Mathematics, it is better to say that it is just a thread from beginning to end.

In theory, they almost got a rough idea.

But when it comes to actual combat, when it comes to specific topics, whether they can apply the knowledge of these theorems proficiently is still a false proposition.

On the podium, Liao Zhixing threw only a small piece of chalk at the table mountain, rolled up his suit sleeves, and asked everyone with a smile. "Does everyone understand what I said?"

"I understand..."

"No……"

Two different voices sounded below.

Liao Zhixing smiled faintly, "Do you think my teaching speed is a bit too fast?"

Everyone nodded together, except for Cheng Nuo, of course.

Liao Zhixing shook his head gently, "No, no, it's not that I speak fast, but your understanding is too slow. I just saw that many students have been immersed in taking notes when I was teaching. Instead, they kept raising their heads. Very few people attend the class."

"I don't object to you taking notes, but you must always remember them with emphasis. Don't just remember what I say, you just write it down."

"and also……"

Let's go~

Liao Zhixing talked a lot about it painstakingly, "At present, this speed is only the most basic speed. If it is not for fear that you can't keep up, I will use half of the book in one class."

One lesson, half a book!

The whole class thought of dying.

Although, they are all learners who have emerged from millions of candidates across the country. But it's just ordinary people!

A lesson and a half book, even if it is called the top pick of this year's college entrance examination, it may not be able to bear it!

"Well, no matter what you understand or don't understand, we will first practice with two questions." Liao Zhixing opened a ppt, and a question appeared on it:

Find all polynomials with complex coefficients satisfying f-ff=0.

The topic is short, it seems simple at first glance.

But often, the simpler the problem, the more difficult the calculation.

"This topic is a bit difficult. You can try it out first, and I'll ask your classmates to answer it later." After speaking, Liao Zhixing took a thermos with medlar and sipped it.

Tsinghua's high-generation teachers are all called difficult questions, and the degree of difficulty should not be underestimated!

This is a hard stubble!

However, since they chose to apply for the Department of Mathematics, they were well prepared to face the math problems.

Under the stage, students from the Department of Mathematics took out pens and papers, frowned, and worked on the paper while frowning.

In the classroom, apart from the sound of the pen tip and the paper rubbing, no other sound can be heard.

The fat and beard-looking classmates are also looking down and writing and drawing on the paper.

Although, he didn't understand much before, and he didn't know what he was calculating.

A minute later, the fat and clueless classmate threw the draft paper aside in frustration.

When he turned his head and was about to check the progress of other students, he suddenly saw Cheng Nuo, who was sitting next to him, who was completely in two worlds in his surroundings!

What made Fatty classmates puzzled was that when other classmates were immersed in solving problems, Cheng Nuo, who was sitting next to him, seemed unmoved. He propped his head with his hands, his eyes moved away. On the table, there was nothing but a notebook. Yes, there are no textbooks or pens.

And the notebook is blank.

All this made the fat classmate wonder how the fellow next to him came to Tsinghua University.

I have tried hard to hear it! Although... it's still tragic, I didn't understand it! But after all, I tried my best!

But you guys who don't even bring textbooks, take notes, and don't do topics, are a bit too much!

It's still in class now, which is somewhat inconvenient.

The chubby classmate decided that after class, he must preach the tutorial. Let Cheng Nuo know when he is lost, don't waste his studies and become a person who is useless to society.

five minutes later……

There are still ten minutes before get out of class.

Liao Zhixing halted everyone's answering questions. He held the desk and asked with a smile, "Well, anyone would volunteer to come up and solve this question?"

Silence, the silence of needle dropping.

No one raised their hands and no one answered.

Liao Zhixing's expression showed a slight embarrassment. "It seems everyone is very shy!"

"In that case, I'll just call a classmate at random!"

After speaking, Liao Zhixing scanned the classroom.

The fat classmate who didn't solve the problem, had a guilty conscience, lowered his head, like an ostrich, wishing to lower his head into the soil.

Liao Zhixing's gaze ~www.readwn.com~ scanned the classroom for a week, and then suddenly fell on the fat classmate.

The chubby classmate who was bowing his head felt the chrysanthemum suddenly tighten.

"Come on, that fat classmate, come up and tell everyone about this question."

The fat classmate raised his head, looked around, and pointed to himself.

"Yes, that's right, it's you, that fat classmate with glasses!" Liao Zhixing said with a smile.

The fat classmate got up with a look of reluctance and stood there blankly.

"This chubby classmate, come here to share with you your ideas for solving the problem. Only by brainstorming together can we make progress together!" After speaking, Liao Zhixing looked at the chubby classmate with encouragement.

The chubby classmate hesitated for a while, bit the bullet and said, "Teacher, I...I won't!"

"No?" Liao Zhixing was taken aback, "This...by the way, what's your name?"

"Li Xiurui." Fatty classmate said weakly.

"Fatty classmate Li Xiurui, yes, I will call you this in the future."

Li Xiurui has a black line.

Teacher, you just call me by name, and the first two modifiers are unnecessary...

"You shouldn't be this!" Liao Zhixing walked back and forth on the podium, and taught him, "This question is difficult, but it is good, but as long as you understand all of what I said before, and you understand it, you still haven't done it Question."

"Teacher, I..." Li Xiurui said.

Teacher Liao raised his hand to stop, "If you don’t believe me, you just call another person in our class to see if you can solve this problem. If you can’t, it means that there is indeed a problem with my teaching speed, if so. , Then it shows that your basic knowledge is not solid enough."

"Then I choose him!"

Li Xiurui stretched out his hand and did not hesitate to choose...Cheng Nuo who was sitting next to him!
