Chapter 513 Are We Number One?

Liu San was stunned for a moment: "Why are you looking at me?"

"It's a pity that you don't want to be a mathematician!" The others laughed.

Zimo also smiled: "Your thinking is also very good. Much better than mine."

Liu San said: "Where, you know this thing better. I don't involve much, just follow my own thinking."

"Let's go. There are still some exams in the afternoon." Instructor Sun led everyone away with a smile.

Instructor Sun: "I invite you to dinner."

Liu San said: "Let me treat you to eat. Let's go."

Instructor Sun was stunned.

Anyway, the money is too much to spend, and the instructor is just invited to have a meal, which is regarded as two months of hard teaching fees.

Seeing Liu San being so generous, Instructor Sun didn't say much.Now I rely on my pension to support my family.My wife doesn't study much, so naturally she doesn't have a good job.Not even a civil servant.After retirement, take that cheap pension.

If it weren't for the working relationship of Instructor Sun, the two of them would still be very tight.

The two of them had a good life, but they were sick or something, so they really didn't dare.After all, the hospital is a place with serious running water.In the past, there were very few clinics that cost a few yuan or more.Most of them are dozens of registrations and hundreds of films.

When encountering some diseases, hundreds of thousands are not enough.

Therefore, in order not to get sick, Instructor Sun almost always relies on running to exercise and make himself less sick.

It is also the most economical type.

But when it comes to spending money, Director Sun has never been stingy.

He has always had hope that he can bring out a champion in his lifetime.

That would be cool.

Liu San came to a hotel: "Let's eat here. It's close to the examination room, and everyone has plenty of time."

Everyone followed.

"Let's eat here." Liu San said.

Everyone looked at it: "It's not cheap. Why don't we go to eat fast food."

Liu San smiled and said: "Don't worry, you don't need to pay. I made a little money before, so it's no problem to treat guests. Let's go."

Zhou Jie asked, "How much is the small money?"

Liu San smiled without saying a word.

When we walked into the hotel, the waiters were very welcoming.

"Give me the best private room." Liu San said.

The waiter was wearing a school uniform at first glance: "Yes. But."

"It's okay. Let's open it. Then order your signature dishes."

Everyone was talking and laughing in the private room.

After eating, everyone left together.

Another exam in the afternoon.It's a physics subject.

One of the most difficult topics is the acceleration mixing variable.

This time, it seems to be much more difficult.

the next day.

Some teams were eliminated directly, and some teams were eliminated.

The overall difficulty of the exam is getting more and more difficult.

Liu San's team was as expected by instructor Sun, and the others stopped in the semi-finals one after another.

And Liu San and Zimo's grades are very stable, and there are a few people from other schools who continue to compete for this thing.

In the end, the remaining 16 people entered the final round.

My brain is about to explode.

All kinds of difficult questions emerge in endlessly.

Everyone followed the trainer's train of thought, and after getting the easy scores, they took the time to study the general ones.

The last 16 people compete for the final challenge.

On the seventh day!
It’s very difficult from the first question!

Mathematical Olympiad is a competitive spirit of the Olympic mathematics competition.

Expand mathematical thinking.

"It's a bit difficult." Like everyone else, Liu San couldn't write on the first question.

After looking at several questions in a row, it is almost difficult to write.

President Wu was patrolling the invigilation room, and the surrounding teachers were also constantly patrolling.They did not speak and did not interfere with students' thinking.

Even walking is very light.

The same is true for Zimo.

Almost all top math students get stuck on the last round.

These aggregate scores ultimately determine the ranking of all schools in the country.

IMO is one of the top competitions in the world, and the national exam basically has several processes of rematch and preliminary rematch.

At present, Liu San is participating in a national mathematics competition mode.

A way to discover mathematics talents through total scores and average performance.It is different from regular exams.

Most people look at the test paper with a frowning face and don't know how to do it at all.

Occasionally, I picked up a pen and did it for a while, then stopped again.

The same is true for Liu San.

One topic is the problem of Archimedes dividing cattle.

Liu San had some impressions and began to think carefully.

The sun god has a herd consisting of male and female cows of four colors: white, black, flower and brown.Among bulls, white bulls outnumber brown bulls.

多出之数相当于黑牛数的1/2+1/3；黑牛数多于棕牛，多出之数相当于花牛数的1/4+1/5；

花牛数多于棕牛数，多出之数县党羽花妞数的1/4+1/5，花牛数是全体棕牛数的1/5+1/6；

Uncle Brown Cow is 1/6+1/7 of the total number of white cows. How is this herd composed?

"It's definitely not possible to use conventional equations." Liu San frowned.

After thinking about it a few times.

Liu San started to write.

I started writing quickly.

设功能公牛为1，母牛为2，白牛为A，黑牛为B，花牛为C，棕牛为D，由题意可以的A1-D1=(1/2+1/3）*B1=5/6*B1
①.
②.
Final A1=140350178787374137344
A2 = 101006732442665484288
The answer is very big.

When Liu San calculated it, it was close to the ringing of the bell.

Everyone sighed and left the examination room.

"It's so difficult. I'm so dazed." A girl from Heilongjiang said.

Another man said: "I have some ideas. It's just that you are not allowed to bring a computer. It's too difficult."

Zimo glanced at Liu San: "How is it?"

"I also have a lot of time to do. If I give a few more days, I guess I can do it. It is impossible for the competition to give so much time." Liu San smiled wryly.

Zimo said: "I will just do a few small questions."

Liu San said: "I guess it's the same. After the seven-day assessment scores come out, the full score assessment should be 140 points."

Seven-day exam, in the morning, a total of 10 points can be scored, and 10 points in the afternoon.A day is 20 minutes.In this way, the total score is 140 in seven days.

The 10 points are evaluated based on the overall performance.

And use rounding to estimate the total score.

"The exam is over. Let's go. Let's get together."

Liu San and Zimo left one after another.

Instructor Sun was waiting outside the door: "There will definitely be top eight this time. As for the specific number, we have to wait for the results."

Everyone is waiting outside.

"Boss Liu, is the last round difficult?" Although everyone knew it in their hearts, they were still very curious.

As a result, Liu San spoke out some questions.

A bunch of people in the public looked confused.

The world of mathematics is indeed very mysterious. After listening to Boss Liu's speech, it was completely as if he hadn't listened.

"Let's go. Go back to school. There will be a re-evaluation later. If you get good grades, you will get a trophy."

Instructor Sun took everyone on the bus and returned to school.

After returning to school, Liu San smiled.

The next few days are normal study.

Until the moment Instructor Sun appeared in the classroom, there was a change!
"Zhou Jie, Liu San, Zimo, you three come out." Instructor Sun stood at the door of the class with a smile.

Zimo looks similar to Liu San.

The three left together.

The whole class looked at the three of them in surprise.

"What are they doing out there?"

"Looking at Teacher Sun like this, there must be a reward!"

"Could it have entered the semi-finals!?"

"I don't know!"

Liu San asked: "Could it be that we won the first place?"

Instructor Sun shook his head, and the corner of his mouth did smile: "No."

Immediately Liu San was surprised, not the first, why is he smiling so happily?
