Chapter 400: Mental arithmetic

On Wednesday afternoon, Qin Fei received a notice from Mr. Zhong Zhiqiang to go to classroom A305 of the No. 3 teaching building.

Take a math Olympiad class.

Longhuai No. 1 Middle School also attaches great importance to the Olympiad competition, after all, students win prizes in such competitions.

That can greatly increase the visibility of the school, so No. 1 Middle School will also set up a team of teachers for Olympiad mathematics to teach these students.

The National Mathematics League in May is about to start in less than a month, and the time is pressing, which is also the first concentrated class of this year's Olympiad class.

Qin Fei is the only representative of the higher level.

A man alone came to the No. 4 school building, which represents the senior class.

Yes.

The layout of the teaching building of Longhuai No. 1 Middle School is also very particular, and each grade almost occupies a teaching building.

So the students in the upper and lower grades.

They rarely see each other, except occasionally in the cafeteria or at the school gate.

So Qin Fei was not familiar with this building, and after looking for a long time, he finally found 305.

But there is no one in it, and it is still a reference room.

Qin Fei studied for a long time, only to find that he ran to Building B, which was B305.

Hehe!

It's really your mother's B, why are you so complicated?

When Qin Fei came to classroom A305,

It was already full, and there was a teacher lecturing, and he was writing something on the blackboard.

Qin Fei couldn't see his front, but he could see his back, and he felt very thin.

And the back of the head is bare.

There is a rumor that the standard configuration of math teachers is that the less hair there is, the higher the level of math teaching.

Hehe, the one in front of me should be top.

Qin Fei was late.

I was embarrassed to say: "Report to the teacher, my Qin Fei, who is eight years old, came to class." ”

Dozens of pairs of eyes in the class looked at him in unison, which made Qin Fei embarrassed.

But soon he stopped looking at him again, and concentrated on the topics on the blackboard, and his pen kept writing and drawing.

"Mediterranean" did not look back at the first time, and did not come back until he finished writing the first question.

Gently looked at Qin Fei.

I looked up and down again.

Pushed his glasses.

"Zhong Zhiqiang told me that there is a good seedling in the higher level, and it is you. The teacher didn't speak a little upright.

"It should be me, I'm the only one to participate in the Olympiad training class. Qin Fei said.

"I heard that you got a perfect score in the last Olympiad paper?"

As soon as Mediterranean's words came out, the stupid thirty or so people inside stopped writing.

He looked at Qin Fei again in surprise.

Out?

A freshman in high school actually got a perfect score?

They wouldn't believe it, because they'd done it all, and it wasn't very difficult.

But the higher level is a perfect score.

When pigs fly.

"Yes, that paper is pretty simple. ”

Qin Fei told the truth, but this caused a lot of dissatisfaction among the big guys.

"This guy is very dragged. ”

"It's easy. ”

"Just him? even took up a precious place for us, brushed us alone, this is the fucking bastard son of the principal. ”

"Damn, a senior brat, go back. ”

"Yes, you know a fart, can you solve binary cubic equations, don't be ashamed. ”

"Do you know anything about Euler's formula?"

“...”

Qin Fei didn't know why, the people inside were suddenly so hostile to him.

It's also strange to thank you, senior, it's just one level higher than you, as if you have an inexplicable sense of superiority.

will treat junior students as mentally retarded and stupid.

In fact, Qin Fei was about the same age as them.

But they can't be blamed entirely, Qin Fei himself doesn't know, it's because of his arrival.

As a result, there was also a ranking test competition between them, and the person at the end of the ranking was eliminated, a cruel game.

Fittest.

This is the list of participants in Longhuai No. 1 Middle School, which is so much, 36 people.

So...... Qin Fei has become a person who cuts in line, and it is natural to be hated.

"Silence, you guys do a good job of this question, I'll ask a question later, I hope any of you can make it. As soon as the Mediterranean words came out, they hurried to solve the problem again.

"Come in. Zhong Zhiqiang's people, he still retains a skeptical attitude.

Qin Fei didn't know this group of coers, but judging from their performance just now, they didn't like them.

So Qin Fei didn't have to deal with them, he ran directly to the last row and sat down.

Stay away from this group.

"Has anyone made it, this question requires strong spatial thinking skills. Mediterranean walked down and asked as he went.

No one answered, all in deep thought, scratching their heads in confusion.

There are also people who knock their heads wildly.

Lunatic!!

"Everyone's thinking should not be rigid, but flexible, spatial imagination should be rich, and attention should be paid to the relationship between points and surfaces. "Teacher Mediterranean keeps giving hints.

"Huang Tianxiang, how is it, have you made it, can you tell me how much the answer is?"

"Teacher, I don't know if it's right or not, I figured out that it's root number three. When Huang Tianxiang said this answer, he was a little hesitant.

When Qin Fei heard this name, he raised his head and glanced at it.

Because the name is all too familiar.

I heard Wu Jing mention it.

The god-like characters of the second level of high school have always been at the top of the list, more stable than Liu Hailu.

In the last semester, I have been famous inside and outside the school, and I have won various awards in mathematics, physics and chemistry many times.

This time, he came for an Olympic national medal.

"Well, yes, sit down, does anyone have any other answers. Mediterranean continued.

He didn't say that Huang Tianxiang was wrong, or yes, weird, ordinary people have already put it down.

No more struggles.

Anyway, it won't be counted, and when the answer is revealed, half of the people will listen to Huang Tianxiang's answer.

I pushed back the answer and found that the answer was correct.

My heart was full of admiration for this person.

Huang Tianxiang is Huang Tianxiang.

Well deserved!!

"Nobody has any other answers, do they? "The Mediterranean repeats it twice.

I picked up the chalk and got ready to start talking.

"Root number three. A certain voice came from the back of the classroom.

.........

Everyone looked at it and took a look, it was the last one to come in, Qin Fei from the eighth class of high school.

Qin Fei didn't bring anything because he was in a hurry, and his desktop didn't have anything.

Not even a piece of paper or a pen.

It shows that he didn't count.

But he had an answer.

"Nonsense, nonsense. Someone immediately refuted it.

Huang Tianxiang's answer is correct, don't come out and be embarrassed by the students of the higher level. ”

"Really, don't pretend if you don't, others have told you the answer, you don't understand it yet, haha laughed. ”

A bunch of people were sneering.

There is also an answer root number 3. ”

Qin Fei didn't care about other people's comments at all, and repeated his answer loudly.

Mediterranean looked at Qin Fei, smiled meaningfully, and said, "You are right. ”

The audience was in an uproar!!

Many people immediately lowered their heads and used Qin Fei's answers to verify, and in the end they all threw down their pens in disappointment.

That's right, indeed.

When Huang Tianxiang heard this answer.

It has already dawned on me.

I ignore the limitation that people can only see straight lines, the problem of overlapping spaces.

couldn't help but glance at Qin Fei more, this person was indeed not simple.

But I feel a little familiar, isn't he the invincible Hot Wheels at the school sports meeting?

Qin Fei?

Yes, it's him.

The boy that Wu Kaiying favors, every time he reads his newsletter, he is extremely excited.

Huang Tianxiang once partnered with Wu Kaiying in the school sports meeting and was responsible for the broadcasting work.

So he remembered Qin Fei.

Unexpectedly.

He is also so good at mathematics, if Wu Kaiying knows, I don't know what he thinks.

"Qin ...... What is flying, have you ever done this question? Teacher Mediterranean asked.

"No, the first time I did it. ”

“???? I haven't even seen you. ”

"I calculated it in my heart. ”

“......”

It's so awesome.

To know.

This problem requires not only great spatial imagination, but also complex calculations.

Surprised, is this really a freshman in high school?

I've definitely read the original question!!
