I Just Want to Be a Quiet Top Student

　　 "No, I don't have an opponent." Shen Qi said.

　　 "You only have 10 points, so Ji has 20 points." Zhou Yuan retorted.

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

　　 "Then why are you participating in the Olympiad?" Zhou Yuan asked.

　　 "Why not, let the fate." Shen Qi said.

　　 Zhou Yuan: "I @￥*@!"

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

　　嚯.

　　 The students under the stage made strange sighs, what the **** is this?

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

　　 The slender bottleneck was twisted and extended. Strangely, the bottle body was not punctured, but the bottleneck entered the bottle and adhered to the bottom of the bottle.

　　 The bottle has no borders, no inside and no outside. It seems that there should not be such a bottle in the three-dimensional Euclidean space.

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

　　 "Give you 1 minute to understand this picture." Sun Erxiong said.

　　All the students showed puzzling expressions, except Shen Qi.

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

　　 The new picture is a circle. It has no strangeness. It is the kind of circle that people often see. The diameter of the circle is indicated by a dotted line inside the circle.

　　 "Dear students, please listen to the question. I tell you that this surface is closed and its connected number is 1. What is its genus? Give you 1 minute of thinking time." Sun Erxiong said.

Hey…

　　 The students gave a wry smile, this thing is so abstract, who can understand it?

brush!

　　 Shen Qi raised his hand, and 10 seconds passed.

　　 "Oh, Shen Qi, have you all learned to answer questions?" Sun Erxiong was a little surprised.

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

　　 "Yes, yes, my brain is cramped." Sun Erxiong smiled and said, "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 topologically represented as a circle, that is, the circumference of this circle and a Mobius belt The boundary is connected, and its connected number is 1, so the genus is 0. The explanation is complete."

　　 Happiness.

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

　　 "No!"

　　 "This TM, who can?" Zhou Yuan asked the sky silently and stared at Shen Qi. He was selected for the Olympiad National Team anyway, and he didn't even understand Shen Qi's explanation.

　　 Shen Qi smiled without explaining.

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

　　 Ou Ye turned his head and glanced at Shen Qi, Shen Qi and her for a second, calculating Ji, mathematics is not just simple addition, subtraction, multiplication and division, or faster than anyone else, can you understand?

　　 The next situation is like this.

　　 "Shen Qi got 10 points!"

　　 "Ou Ye gets 10 points!"

　　 "Shen Qi got 10 points!"

　　 "Shen Qi gets another 10 points!"

　　 "Ou Ye gets 10 points!"

　　...

　　 Shen Qi and Ou Ye entered the heads-up mode.

　　Pure numerical calculations, quick calculations, Ou Ye is always the first to raise his hand and give the correct answer.

　　 Question types that require strong logical deduction, understanding of abstract graphics, and comprehensive use of various mathematical knowledge, Shen Qi accepts them all.

　　 After 11 questions were answered, Shen Qi got 70 points, Ou Ye got 40 points, and the remaining 24 students got 0 points.

　　 was hit, suffered a severe crit. The remaining 24 students have never felt such a failure. Shen Qi and Ou Ye, a man and a woman, are very perverted. They play with logical deduction and abstract concepts. They can't play with Shen Qi. They can't play Ou Ye with mental arithmetic and quick math with huge amounts of information.

　　 "Okay, the last question, question 12." Sun Erxiong has a general understanding of the true level of the 26 students. Shen Qi, the IMO perfect score champion, is indeed well-deserved. The only girl in the math camp, Ou Ye, has her unique arithmetic skills. The remaining 24 students, well, need further observation.

"The last question will not be projected on the screen. I will dictate it." Sun Erxiong said, "So you have to **** up your ears and listen carefully. I can give you a hint. The last question is pure mental arithmetic, especially simple. , Elementary school students who have learned mental arithmetic can give the correct answer immediately. This is a sub-question."

　　 Everyone under the stage is gearing up to send sub-questions. You must get points. Zero Duck Egg is too shameful. They never scored 0 points in their respective high schools. The full marks are normal.

　　 Shen Qi closed his eyes and whispered, "I have scored 70 points and I am very tired. I give up on the last question. Zhou Yuan, come on."

　　 "Okay, I will definitely defeat Ji Ji!" Since entering the Mathematics Camp of Peking University, Guo Zihao contestant Zhou Yu'an has held back his stomach, and he is determined to win the last question.

"Little ones!" Sun Erxiong yelled with a tone of voice, "Listen to my old grandson, 725 multiplied by 18 divided by 25 multiplied by 337 and then subtracted by 109 and then divided by 5. What is the UU reading www.uukānshu.com? Please answer now!"

brush!

　　 Brush!

　　 Brush!

　　 a dozen or twenty arms raised up.

　　 "Zhou Yuan! Your hand raised first, come, please give your answer." Sun Erxiong looked at Zhou Yuan and made a please gesture.

　　 Zhou Yuan was very excited. After Shen Qi abstained, he finally grabbed the right to answer one question. It was not easy.

　　 Steady and steady, Zhou Yuan said confidently: "My answer is 28,331."

　　 "Wrong! Zhou Yuan deducted 10 points, and the final score was negative 10 points!" Sun Erxiong drank.

　　 "Fuck..." Zhou Yuan almost fainted, why is life so difficult!

　　 Shen Qi suddenly opened his eyes: "Zhou Yuan, you idiot, silly dog, can this be wrong?"

　　Life has been so difficult, Shen Qi, don't you want to dismantle it, okay?

　　 Zhou Yuan covered his face and did not speak, minus 10 points, and meowed a bit. I have never scored too much negative points in my entire life, so it's a shame.

　　 "Ou Ye, you are the second hand raised, please continue to answer, quickly, immediately!" Sun Erxiong looked at Ou Ye.

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

Sun Erxiong: "The answer is correct. Ou Ye got 10 points! Today's general knowledge test and math professional test are all over. This class is a bottom test. Don't be nervous if it's okay. You can rest in the classroom for 20 minutes, and you can also go out and walk around. , 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 common sense test and the math professional test must be recorded?" Zhou Yuan asked anxiously.

　　 "Teacher Sun hasn't said it all, let's get the bottom line, don't be nervous if it's okay." Shen Qi comforted.
