Reborn Xueba, you don't really think that studying is difficult, do you?

When Ye Tianhe brought Lin Bei and six people into the classroom, there were already many people sitting inside.

Well, there are nearly two hundred of them, almost more than half of the participating students this time.

Most of them are students, and a small number of them are teachers who lead the team. Basically, the big ones lead the small ones.

Although everyone came to have a good rest, almost none of them really rested. Instead, men and women gathered together, and the communication was in full swing, so excited.

At the same time, there is also an unknown teacher on the podium, who is showing a PPT and talking about some good Mathematical Olympiad examples.

Of course, many people listen to these examples, but it seems that not many actually do it.

Obviously, the few who can come here to participate in the competition are fools. Before coming, the coach of the team may have reminded them that it is good to listen to these sample problems, and don't spend too much time and energy on solving them.

But with the entry of Lin Bei and others from the third middle school, the scene was naturally different.

This classroom is very large and has a stepped shape. Although it can accommodate many people, it can actually seat more.

Latecomers almost always go backwards. Firstly, sitting in the back can rest better, and secondly, sitting in the front is too conspicuous, and it is easy to be targeted by the teacher's questions on stage.

If you do not have a certain strength, it is best not to sit in front.

Of course, the teams from Lincheng No. [-] and No. [-] Middle School, Hong Hu Zhi and Threesome must sit at the front.

After all, these four schools are the four best schools in Lincheng, and the participating teams are also the strongest.

Especially the No. 50 Middle School directly occupied a large area. After all, No. [-] Middle School had a large number of people, nearly [-] people participated in the competition.

The Second High School is the second, with about 30 people, followed by Hong Hu Zhi and Threesome, with only more than 20 people.

But these 20 people are much better than other schools.

and so……

The four schools occupy the best four areas in the front, where there are both internal communication and external discussions.

It is said to be a discussion, but it is actually a secret competition to see which school's people are the first to do the example problems taught by the teacher on the stage, so as to show the strength of the school.

As the saying goes, where there are people, there are rivers and lakes, and where there are rivers and lakes, there are disputes. This is true.

Although the competition only started in the afternoon.

But the competition among the major schools has begun now.

All the students who can participate in the Mathematical Olympiad are the best among the students of each school.

For each other, no one will admit defeat.

At this moment, it is the warm-up of the competition.

of course.

This warm-up is also limited to No. [-] and No. [-] Middle Schools, Honghuzhi and Sanrenxing four schools.

After all, only these four schools have the strength to compete ahead of time, and the other schools are too far behind. Let alone competing with the front, it is good to be able to barely protect themselves.

and so……

In the four best areas in front of the classroom, there are only people from No. [-] and No. [-] middle schools, Hong Hu Zhi and threesomes.

The rest of the school contestants not only sat in the back, but also were several rows away from the four schools. They obviously didn't want to get too close and be affected.

If it is difficult to understand, just compare the scene of the martial arts conference in the martial arts movie.

The four most powerful sects sit in the top four best positions, while the rest of the sects stay far away.

But right now.

However, there was a fifth sect, under the gaze of many people, arrogantly passed all the people behind, and came to the front, not to mention, and even sat directly in the middle of the first four sects, it seemed that this sect was the most powerful sect. The head of the five sects is general.

All of a sudden, everyone present was counted as one, their eyes flashed and their expressions changed.

Among them, Honghu Zhi and the three of them frowned even more, and there was a glimmer of gloom in them.

"May I ask what school is here, so rampant?"

"The middle one is the best seat. No one dared to sit in No. [-] and No. [-] Middle School, Hong Hu Zhi and Threesome. As a result, there were only six or seven newcomers from the school, but they sat on it directly. People should pay attention to it!"

"What's the matter, are they going to pick four?"

"Σ(Д) is amazing!!!"

Everyone looked at the person in disbelief.

As for who is coming, I don't need to say much, everyone knows, of course, there is no doubt that there are seven people in the third class.

As the principal of No. [-] Middle School, Ge Tianxing could be described as a domineering group. He sat in the middle of No. [-] No. [-] Middle School directly, and then swept his eyes around, with a provocative look on his face.

Ok.

It is so confident that the people under him are capable.

And as the head of a school, it doesn't seem too much for him to occupy the best position, right?
Li Hao, Xu Xian and Fang Zheng had never seen such a scene before, and they were slightly nervous at the moment.

But Lin Bei, Zhao Qinghan and Zeng Xi all looked calm and calm.

And the three of them ignored the gazes from the surroundings, but immediately looked at the sample questions being shown on the podium.

Especially Lin Bei, it was like a bloodthirsty hungry wolf met a little lamb, and put all his mind directly into it.

This question is quite interesting.

only see...

[S is the set of all real numbers greater than -1, try to find all the functions f from S to S that satisfy all x, y, f ( x + f ( y )+ xf ( y ))= y + f ( x )+ yf ( x ), and for –1< x <0 and 0< x , f ( x )/ x is strictly increasing. 】

Difficult, but not difficult.

It takes about 1 minute to make it.

But this is not the point.

The point is that it is shown on the multimedia, but not only this one question, but also the second, third and fourth questions...

The difficulty of each of the following questions is the same as that of the first one. Although it is not as good as Ge Tianxing's previous paper questions on the car, it is more complicated than what Lin Bei usually does.

Immediately, Lin Bei's feeling came up, and he couldn't even control the flow of blood, and he rushed to a certain place madly, adrenaline, dopamine, and glucocorticoid all soared.

"I can't help it, I can't help it, I have to solve it on the spot, no one will say anything, right?"

Thinking of doing it, Lin Bei didn't care about the strange eyes around him, and directly took out his beloved pen and paper.

Then, start working in public.

When others look at these questions, they really just look at them, and actually do very little.

But Lin Bei was different, he started to do it directly, and the speed of "scrambling" was so fast, it seemed that he was holding back too hard.

In comparison, Zhao Qinghan next to her was much more reserved, she just frowned and thought quickly in her heart.

Zeng Xi quietly took out a pen and paper, keeping a low profile.

As for Li Hao, Xu Xian, and Fang Zheng, they didn't think about it and didn't do it. After all, the strength of the three of them is not enough.

But even so.

It's enough for them to catch people's attention.

A group of seven people occupied the best position as soon as they came, and they did not take Yierzhong and Honghuzhi's three people into consideration.

Some people glanced at the blackboard and started to solve the problem, and they didn't seem to pay attention to the teacher who was posing the problem on the stage.

Immediately, there were many people around talking about it.

"Who are these people?"

"How dare you be so brave?"

"Don't they know that the front row is the exclusive venue for No. [-] and No. [-] Middle School and Hong Hu Zhi's threesome?"

"They are only seven people, dare to sit on it?"

"Don't they know that the example questions on the blackboard are just example questions, unless they want to compete with No. [-] Middle School and Honghuzhi in advance, otherwise they don't need us to do it at all?"

"Now some of them have started directly. Could it be that they want to compete with the gods of No. [-] Middle School Ye Tian, ​​No. [-] Middle School Luo Lin, Honghu Zhi Lu Yuan, and Threesome Zhang Chao in advance???"
