I Just Want to Be a Quiet Top Student

"No, I have no opponent." Shen Qi said.

"You only have 10 points, so count Ji's 20 points." Zhou Yu'an retorted.

"Mathematics is not for competition." Shen Qi shook his head.

"Then why did you participate in the Olympiad competition?" Zhou Yu'an asked.

"No reason, just follow fate." Shen Qi said.

Zhou Yu'an: "I @￥*@!"

"Hey, Shen Qi, Zhou Yu'an, what are you two talking about? Please pay attention to the discipline of the math camp!" Sun Erxiong reminded, and then pointed to the projection screen: "Please see the fourth question."

Huh.

The students under the stage sighed strangely, what the hell is this?

A bottle is displayed on the screen, a bottle made of surfaces and curves.

The slender neck of the bottle twists and extends. Strangely, the body of the bottle is not pierced, but the neck of the bottle enters the bottle and sticks to the bottom of the bottle.

The bottle is boundless, has no inside and no outside, and it seems that this kind of bottle should not exist in the three-dimensional Euclidean space.

There is a prompt on the screen: "The bottle is one-sided, and its one-dimensional connectivity number is 3, that is, the genus is 1."

"I'll give you 1 minute to understand this picture." Sun Erxiong said.

All the students showed puzzled expressions, except Shen Qi.

After 1 minute, the projection screen switches to a new screen.

The new picture is a circle, and there is nothing strange about it. It is the kind of circle that people often see. The diameter of the circle is indicated by a dotted line inside the circle.

"Students, please listen to the question. Let me tell you that this surface is closed and its connectivity number is 1. So what is its genus? I will give you 1 minute to think about it." Sun Erxiong said.

Why……

The students smiled wryly, this thing is so abstract, who can understand it?

brush!

Shen Qi raised his hand, and 10 seconds had passed.

"Hey, Shen Qi, have you learned to answer quickly?" Sun Erxiong was a little surprised.

"Mr. Sun, isn't this the answering session?" Shen Qi asked back.

"Yes, yes, my brain is cramping." Sun Erxiong smiled, and said again: "Please tell me your answer."

Shen Qi gave the answer: "The genus of this closed surface is 0."

Sun Erxiong asked: "Why?"

Shen Qi: "From the conditions given by the Klein bottle in the previous picture, we can deduce that this closed surface can be expressed topologically as a circular domain, that is, the circumference of this circular domain and a Möbius strip The boundary is connected, and its connectivity number is 1, so the genus is 0. The explanation is over."

clap clap.

Sun Erxiong applauded, and then asked the students in the audience: "Can you understand Shen Qi's explanation?"

"cannot!"

"This shit, who can?" Zhou Yu'an stared at Shen Qi speechlessly. He had been selected for the Olympiad national team, but he couldn't even understand Shen Qi's explanation.

Shen Qi smiled without explaining.

Sun Erxiong: "If you can't, then you can't. Shen Qi gets 10 points, everyone else gets 0 points, next question."

Ouye turned his head and glanced at Shen Qi, Shen Qi and her looked at each other for a second, Calculation Ji, mathematics is not just simple addition, subtraction, multiplication and division, or you can calculate faster than anyone else, can you understand?

The next situation is like this.

"Shen Qi scored 10 points!"

"Ouye scored 10 points!"

"Shen Qi scored 10 points!"

"Shen Qi scored another 10 points!"

"Ouye scored 10 points!"

...

Shen Qi and Ouye entered the heads-up mode.

For pure numerical calculations and quick calculations, Ouye is always the first to raise his hand and give the correct answer.

Shen Qi accepted all the question types that required strong logical deduction, understanding of abstract graphics, and comprehensive application of various mathematical knowledge.

After answering 11 questions, Shen Qi got 70 points, Ou Ye got 40 points, and the other 24 students got 0 points.

Hit, suffered a severe crit. The other 24 students have never felt such a failure before. Shen Qi and Ouye, a man and a woman, are very perverted. They play with logical derivation and abstract concepts. They can't play against Shen Qi. They can't compete with Ouye in mental calculation and quick calculation with huge amounts of information.

"Okay, the last question, question 12." Sun Erxiong had a general understanding of the real level of the 26 students. Shen Qi, the IMO perfect score champion, really deserved her reputation. The only girl in the math camp, Ouye, has her unique arithmetic skills. The remaining twenty-four students, well, need further observation.

"The last question will not be projected on the screen, I will dictate." Sun Erxiong said, "So you have to prick your ears and listen carefully. I can give you a little hint. The last question is purely mental calculation, which is very simple. , Elementary school students who have learned mental arithmetic and quick calculation can give the correct answer immediately, this is a sub-question given by Tao.”

Everyone in the audience was gearing up to give points, and they had to get points. Zero duck eggs was too shameful. How could they ever get 0 points in their respective high schools? Full marks are the norm.

Shen Qi closed his eyes, and said softly, "I've already scored 70 points. I'm very tired. I'll give up on the last question. Zhou Yu'an, come on."

"Okay, I will definitely defeat Calculus Ji!" Ever since he entered Yanda's mathematics camp, Zhou Yu'an, a national player, has been holding back his stomach, and he is determined to win the last question.

"Little ones!" Sun Erxiong yelled in a tone of voice, "Listen to my old grandson, what is 725 times 18 divided by 25 times 337 minus 109 and divided by 5? Please answer immediately!"

brush!

Brush!

Swipe!

A dozen or twenty arms were brushed up.

"Zhou Yu'an! Raise your hand first, come, please give your answer." Sun Erxiong looked at Zhou Yu'an and made a gesture of please.

Zhou Yu'an was very excited. With Shen Qi abstaining, he finally got the right to answer a question. It was not easy.

Steady, Zhou Yu'an said confidently, "My answer is twenty-eight thousand three hundred and thirty-one."

"Wrong! Zhou Yu'an deducted 10 points, and the final score was minus 10 points!" Sun Erxiong shouted.

"Damn it..." Zhou Yu'an almost fainted, why is life so difficult!

Shen Qi suddenly opened his eyes: "Zhou Yu'an, you idiot, useless dog, how can this be wrong?"

Life is already so difficult, Shen Qi, don't expose it anymore, okay?

Zhou Yu'an covered his face and didn't speak. He lost 10 points and meowed. I've never had a negative score in my life. It's a shame.

"Ouye, you are the second to raise your hand, please answer, quickly, immediately!" Sun Erxiong looked at Ouye.

Ouye said slowly: "Thirty-five thousand one hundred and sixty-one."

Sun Erxiong: "The answer is correct, Ouye gets 10 points! Today's general knowledge test and mathematics major test are all over. This class is just a test. Don't be nervous if you are fine. Everyone can rest in the classroom for 20 minutes, or you can go out for a walk , Go to the bathroom."

After speaking, Sun Erxiong and his assistant turned off the projector and left the classroom.

"Shen Qi, the scores of the general knowledge test and the math major test must be recorded, right?" Zhou Yu'an asked anxiously.

"Didn't Teacher Sun say it all, just find out, don't be nervous if you're fine." Shen Qi comforted.
