Chapter 49

In the face of the high difficulty of the examination, the candidates face dignified one by one.

In the face of these problems, Lu Li has the feeling of racking his brains. The difficulty is beyond imagination, and it seems to be even more difficult than the "previous international Olympic mathematics competition questions" that Lu Li once brushed.

In the office building of Shuimu University.

Many teachers and professors of the Organizing Committee of the Olympic mathematics competition were surprised when they saw this paper.

"It's difficult It's a little scary! "

A graduate of mathematics staff, looking at this paper, forehead are out of a cold sweat.

If I had done this paper, I'm afraid Did you fail the exam?

"What is the Olympiad? It's about selecting talent for the national team. The selected people are going to take part in the International Olympiad Mathematics Competition. "

An old professor praised this paper very much. "This paper can't be finished. What international competition do you want to take part in? Don't make a fool of yourself. "

"Mr. Wang, you are right!"

Everyone nodded and echoed.

But in private, he secretly said: the truth is right, but We can choose the members of the national team during the winter camp training!

This national competition, we can reduce the difficulty of some questions, only increase the difficulty of individual questions, don't let everyone die too ugly!

I'm afraid that many people will cry when your paper comes out. The whole team was destroyed, and many candidates returned with zero eggs. How can this be embarrassing?

In the examination room.

As time goes by, the candidates have been shivering.

Some face blue, some eyes straight, some heart if dead, some silent tears.

Can go to today, can go to this step, can come to the national competition examination room, who is not Xueba? Who is not the most beautiful one?

However In front of this paper, the scenery of the past, the glory of the past, the pride of the past, like a soap bubble, fly ash and smoke out in an instant, broke clean.

Tear open the gorgeous coat, leaving only bloody wounds.

I always thought I had a high IQ, but now I find that In front of this paper, I am just a mentally retarded!

Lu Li also felt that he was a "fake bully".

After finishing the three questions with solutions, it took half an hour for the fourth question to come out.

Next, question five what the fuck! What the hell is this? It seems to be a geometric problem, but it's actually an algebraic problem. It's back to geometry by solving it with algebra.

I can't do it. I'm in a mess!

Lu Li let out a long breath, put aside the fifth question and did the sixth one first.

This question

"There are 17 people in a QQ group, each of them chatting and sending messages to others in private. They discussed three different topics. Each two people only discuss one topic. Verification: at least three of these people are talking about the same topic. "

SHENTE QQ group! I use wechat!

Why should we have a private chat when we discuss topics in a group? Don't you know how to send a group directly? Even if it's about driving, you don't need to talk about it in private. You should have a collective discussion!

Hemp wheat skin! I hate driving without a group. I'm just chatting!

Lu Li secretly scolded a few words, but his mind was inspired, and he soon found the way to understand the problem.

Sure enough, driving is good for physical and mental health!

The sixth problem was solved quickly. And then Lu Li looked at the fifth question again.

"Four real numbers, the product of any three of them and the fourth number are equal to 2. Find all the possible values of these four numbers."

2…… 2…… Love It's all made!

Love when you die. It's not pleasant if you don't love thoroughly!

I don't know if it's the inspiration of driving and flying. Suddenly, Lu Li has a flash of inspiration and comes up with the idea of understanding.

Some questions, with a layer of yarn, vaguely see the direction, but always hover outside the door, not the door.

Only by tearing off this layer of camouflage and finding the right direction can we drive straight in, attack the Yellow Dragon and kill seven in and seven out.

The surging passion, like a raging tide, tossed back and forth several times, until the momentum, a thousand miles!

It's done!

There are so many beauties in the National Games, which make countless heroes bow down.

Some have broken their halberds into sand, some have broken their heads into blood, and some are still struggling.

And I Just feel dull!

Lu Li put away his water pen and felt empty, just like sage time.

……

The test is over!

Lu Li also felt physically and mentally exhausted, and his whole body was empty. So don't drive if you have a bad kidney Oh, no, stop learning Mathematical Olympiad. I can't bear it.

After taking a deep breath, Lu Li got up and walked out of the examination room.

In the green belt outside the examination room, Lu Li meets Liu Qin.

At the moment, Liu Qin looks depressed and unhappy."What's the matter?"

Lu Li went up and asked with concern.

"I have a question Not finished! "

Liu Qin looked bitterly at Lu Li with red eyes. "It took me too long to think about the solution. When I came up with the solution, I didn't have enough time. I didn't finish all the steps, so I wrote the answers

"That's it

Lu Li smiles, "it doesn't matter! You just omitted a few steps, the problem has been solved, at most a little point deduction. Besides, what if it doesn't work out? Look at the others... "

Looking in the direction indicated by Lu Li, Liu Qin sees Out of the examination room of the candidates, one by one sad face, such as grief.

"You mean I've already done well in the exam? "

Liu Qin was a little relieved. "I made an appointment with you to take part in the international competition. I I always worry about being eliminated. "

"Don't worry! It won't be

Lu Li comforted him and pointed to the exit of the examination room. "Look, Zhang Yu and some of them have come out. Ask them later. I can assure you that you did well in the exam

With that, Lu Li waved to several other teammates in Sichuan Province, "this way! This way

Zhang Yu, Yang Wenli and Wang Yujia saw Lu Li waving and quickly came up.

"You How was the exam? "

Liu Qin was very concerned about the results and asked the other three.

"Don't mention it!"

With a long sigh, Yang Wenli's face was full of sadness and wrinkles on his fat face, "this topic It's too hard! Get a hammer! I've just come up with three questions. "

"I've just done two questions! Hemp wheat skin! Which son of a tortoise asked the question? He's the first one in Japan! Make a shovel

Wang Yujia was so angry that he couldn't speak English any more. He was full of the flavor of Xichuan.

"I hung up, too."

Zhang Yu can't stand the image of cool brother any more. Her face is already full of sadness. "I only did three questions. Others I can't think of a solution at all. "

With that, Zhang Yu looked up at Lu Li and Liu Qin and asked, "what about you? How was your exam? "

"Alas! Don't say that. "

Lu Li sighed, "if you don't say it's OK, it's even worse if you say it."

"All right! No more

Zhang Yu three people listen to this, also feel that Lu Li they must hang up.

Forget it! Forget it!
