From Almighty Scholar to Chief Scientist

Chapter 36 What are you writing about, boss?

Is this the point?
Isn't the point about your full marks?

To this, Lin Xiao can only express that it is obvious that being handsome is the key point.

Just kidding, full marks are only for a while, handsome is a lifetime, not to mention, getting full marks in competitions is a basic practice for Lin Xiao, and he doesn't care about praise or not.

And he will only care about those who praise him for being handsome.

"Ahem, he's really handsome, but you and your girlfriend can discuss this matter in depth later on. Okay, you should sit down first."

Chen Song didn't expect that this guy with thick eyebrows and big eyes was quite narcissistic, but he didn't bother to get entangled. He waved his hand and asked Lin Xiao to sit down, and then continued to report the results of other students.

And when he was studying the grades of other students, he didn't specifically ask this student to stand up. Obviously, he just wanted to know Lin Xiao, and he was not interested in other students.

In this exam, except Lin Xiao's No.1 score was perfect, No.2's score was only in the early 3s, and No.90's score was even more than [-] points.

The scores after that were getting lower and lower. However, Chen Song did not continue to report when the score was [-] points. Obviously, there were still students with scores below [-] points, but Chen Song did not take care of their face. Say.

"Okay, the results are finished. The members of the training team and the students who are observing are among them. If you feel that your grades are not good, then work harder."

"Okay, what about today's class, I will specifically explain the exam papers to you."

Then Professor Chen Song talked about the papers.

There is nothing to say about the test papers. Lin Xiao didn't even bring the test papers, so he couldn't listen to them.

Moreover, it was boring to listen to, because the problem-solving methods taught by Professor Chen are all standard methods, and he has considered them when writing, but these methods are too basic, requiring many words and steps, and he I was PASS when I figured it out.

He is lazy and basically uses more convenient methods to do it.

So, he gave up listening to the lecture, and then opened the abstract algebra he brought over, and continued to read.

Because after reading advanced algebra, he already has a certain foundation to understand abstract algebra. Generally speaking, abstract algebra is also arranged to be learned after advanced algebra.

However, there is no necessary connection between the two. Abstract algebra, also known as modern algebra, is closely related to group theory. It can be said that abstract algebra is the prerequisite knowledge of group theory, and group theory is also an important branch of abstract algebra.

So entering abstract algebra, that is, entering a deeper level of algebra, is naturally not low in terms of difficulty. After all, just look at the name, 'abstract', and you will know that it is difficult. Looking at the masterpieces of abstract masters, how many people can understand?

Of course, abstract algebra is difficult, and it naturally has an important impact on all modern mathematics and some other scientific fields, so its status is still relatively high.

Just looking at it like this, Lin Xiao gradually indulged in it and entered the state of learning.

As for the students around when they saw him bring out an inexplicable textbook, some of them simply glanced at it, but after a few glances, they felt that their eyes were blind. What was the thing on it?Why can't I understand anything?

Then he quickly avoided his eyes and looked at the blackboard again, only to be even more shocked on his face, hey, why is the blackboard full?

Eh?Teacher, why are you going to wipe the blackboard?
In the end, the unlucky guy could only cry without tears.

Everyone is a math genius, but obviously there is a difference between a math genius and a math genius.

In this way, Mr. Chen Song talked all the way to the last question.

He didn't continue talking, but looked in Lin Xiao's direction and shouted, "Student Lin Xiao."

Lin Xiao didn't respond.

"Student Lin Xiao?" Chen Song called again.

At this time, the student next to Lin Xiao pushed him, and he finally came back to his senses, and then asked with a puzzled look, "What's wrong?"

"The teacher is calling you."

Lin Xiao quickly stood up and said, "Teacher?"

Chen Song shook his head helplessly, but he didn't worry about Lin Xiao's failure to attend the class. His class was originally an evaluation paper, and Lin Xiao got full marks. Of course, he had the unconditional right not to attend the class.

Then he said to all the students: "The last question of our exam is the most difficult one in this exam, and only student Lin Xiao got a full score, followed by No.2 student Ouyang who got 11 points. There are 5 students who also got scores ranging from [-] to [-], and the rest of the students got no score."

"And Lin Xiao's method on this question is very good, so I hope everyone can learn it. Let's also listen to how Lin Xiao came up with this method."

Lin Xiao touched his nose, he didn't bring the test paper, his process was written on the test paper.

Also, is that question really that difficult?
He thinks it's pretty good.

However, if the teacher told him to go up, he could only go up. Anyway, he still had an impression, so he could recalculate and it would be over, so it was not a big problem.

So he got up from his seat and walked to the stage.

Chen Song handed him the blackboard pen, but seeing that he didn't bring the test paper, he couldn't help but ask, "Where's your test paper?"

"The test papers are in the hotel."

Chen Song: "..."

Didn't bring any test papers to class?
Could it be that Lin Xiao was confident enough to get full marks after the exam?
But without the paper, Lin Xiao probably couldn't write it. After all, the process of this question was quite long, and there were a lot of calculations in the middle, so Lin Xiao might not be able to remember all of them.

So he asked: "Then can you write? If you really can't, you can talk about your thinking."

Lin Xiao waved his hands, and said indifferently: "Ah, it's okay, it's not in the way, just do the calculation again, I calculated it faster, and I still have a little impression."

Everyone was speechless.

Just do the math again?Alright, you're big guy, get on your show.

Chen Song didn't say anything. Some math geniuses are like this. If they forget a theorem or formula, they just re-deduce it, so they 'remember' it.

Although it is quite difficult for Lin Xiao to repeat such a complicated calculation, it is not necessarily impossible.

So he stepped aside and looked forward to Lin Xiao's performance.

Lin Xiao took the pen and looked at the questions Chen Song had written on the blackboard.

[For a positive integer n, there are exactly 36 different prime numbers that divide n.For k=1, 2, ..., 5, remember [(k-1)n/5, kn/5] the number of integers that are relatively prime to n is taught as Cn, and it is known that C1, C2, ..., C5 are incomplete Similarly, prove that ∑5>j>i>1(Ci -Cj)>2^36. 】

"Well... yes."

After briefly looking at the question and adding his own impression, he quickly said, "Everyone see this ∑5>j>i>1, what can you think of?"

"It's very simple, the principle of tolerance and exclusion!"

"So next we write the expression using the inclusion-exclusion theorem."

Then, he wrote on the blackboard.

【证明：不妨设n=P1^a1*P2^a2……*P36^a36.
Definition: f(n)=……]

Looking at what he was writing on the blackboard, more than half of the math geniuses below were still stunned.

Boss, what are you writing about? !
