I Just Want to Be a Quiet Top Student

　　 "Andrew Wiles, in fact, I have heard of this big name, a great man in contemporary mathematics." Shen Qi said, his sight never looked away from Wiles on the podium.

　　 Zhou Yu'an took it for granted: "Nonsense, the Philippine Prize winner, proved the super difficult Fermat's Last Theorem, who has never heard of Wiles?"

　　 "But we didn't know that this old man was Wiles!" The two said in unison.

　　 "Such a big person still needs to go to the supermarket to buy salad dressing in person?" Shen Qi expressed doubts. Little bosses like his dad never go to the supermarket, just order what they want to buy.

　　 "Hey, Shen Qi, Zhou Yuan, what are you two muttering? Are you familiar with Professor Wiles?" the deputy leader asked.

　　 Shen Qi shook his head: "I don't know him well, but I know that Professor Wiles is a master of mathematics, and his skills are quite deep. Maybe he is the best local master."

"I need you to say it? Be quiet, listen to Professor Wiles reading the competition rules, it is very rare for the organizing committee to invite him to be the leader of the jury group." The deputy team leader plugged in the earplugs again, and the earplugs were connected to the simultaneous translation. equipment.

"Unexpectedly, there are weak chickens in the same city who can't do subtraction within 10, and there are mathematics masters and masters. The difference in strength is too great. It is simply the difference between the five scums and the **** of war." Shen Qidai Put on your earplugs and listen to Wiles reading the rules of the competition.

"...The competition rules have been read out, children, the last thing I want to say is, where there are numbers, there is beauty. We are engaged in a beautiful job, worthy of our life's work." Wiles' last One sentence is quoted from the Greek mathematician Proclos, who quoted this article at the 1998 Philippine Prize Award Ceremony and quoted it again today.

　　 The auditorium roared with applause. The British, foreigners, Europeans, Americans, Asians, players from various countries, coaching teams, and security guards to maintain order, everyone paid the highest respect to Wiles.

　　 People seem to have forgotten that Wiles is not the protagonist of this IMO, he is just a judge, who reads the competition rules routinely.

　　 But does it matter?

　　 Shen Qi was deeply shocked. It turned out to be the best in learning, in exchange for the supreme glory and the respect of the world, this kind of glory and respect regardless of nationality, regardless of race or color.

　　 "I really hope that one day, I can also achieve such a great achievement as Professor Wiles. What is Guangzong Yaozu? This is how Guangzong Yaozu rules the rivers and lakes."

　　 Shen Qi felt that this trip abroad was very rewarding, and some scenes were not immersive to experience, and they could not feel the shock that touched the soul.

　　 Professor Wiles poured a bowl of fierce chicken soup for more than 600 young players from 102 countries. Young talents from Europe, Asia, the United States, Africa, and Australia were gearing up, and the battle was about to start.

　　 On the morning of July 26, the first day of this IMO competition kicked off. The venue was London South Bank University.

　　Professor Wiles, the leader of the judges group, has fully understood the competition rules and schedule. There are a total of six questions. There will be three questions today and three questions tomorrow. Each question is 7 points, and the maximum score is 42 points.

　　The competition time on each competition day is 4.5 hours. You can bring any stationery and drawing tools, and all electronic equipment is not allowed to be brought into the competition field.

　　Because the competition time is long, each contestant can bring their own food and drink into the arena, and can bring no more than three reference materials.

　　 Yeah, this is an open-book exam, you can read the book by eating and drinking.

　　 IMO looks so relaxed, almost like a summer camp.

　　 But is that really the case?

Obviously not.

　　 The food that Shen Qi brought was muffins and bear biscuits, and the drinks were mineral water and Red Bull bought in a local supermarket. The three reference materials were "Introduction to Analytical Techniques", "The Art of Presumption", and "Research on Analytical Geometry and Differential Geometry".

　　 When Shen Qi got the first day of the competition examination papers, he found that the three reference books were basically useless. The most useful ones were Bear Biscuit and Red Bull.

　　 The three questions on the first day test paper have been translated into Chinese. Shen Qi must first crack the first question because it is a threshold question.

　　 There is a line of cold Chinese characters printed on the surface of the volume: "The first question, the threshold question. This question is 7 points for correct answers, and -7 points for incorrect answers and no answers."

　　 The threshold question for the first question is really frantic. You get a maximum of 7 points for correct answers, and you think you can get 0 points for incorrect answers and leave it blank? nonexistent.

　　 See clearly, the threshold question is -7 points for incorrect answers and no answers.

　　 means that the bottom line of this IMO test paper is not 0 points, but -7 points.

　　 If there is a slight mistake, it is death.

　　I came to Great Britain all the way, and brought a negative score home, and asked if you were ashamed?

　　 Zero Duck Eggs have been boiled, and after waiting for a long time, I finally waited till today.

　　 Shen Qi did not dare to be careless, he reviewed the title of the threshold question for the third time:

　　 "The mathematics professor at Oxford University has three smart students, they are Tom, Jerry and Thomas."

　　 "One day, the professor wants to test which of the three students is the smartest."

　　 "The professor put a note on each of the three students' foreheads with numbers written on them."

　　 "Tom, Jerry and Thomas can see the numbers on the foreheads of the other two classmates, but they can't see the numbers on their foreheads."

　　 "The professor said, the numbers on your forehead notes are all positive integers, and two numbers are added together to get another number. Then Tom, let me ask you, what is the number on your forehead?"

　　 "Tom said, sorry professor, I don't know."

　　 "The professor asked Jerry again, hey, Jerry, how about you, do you know what your number is?"

　　 "Jerry said, sorry professor, I don't know."

　　 "The professor continues to ask Thomas, UU reading www.uukanshu.com, dear Thomas, you are the only one left. What is your answer?"

　　 "Thomas answered immediately, Professor, my number is 144."

　　 "The professor nodded, congratulations Thomas, your answer is correct."

　　 "If you understand the above short story, may the numbers on Tom and Jerry's foreheads be () and () respectively."

　　 The above is the entire content of the first threshold question. A correct answer is 7 points, and a wrong answer or no answer is -7 points.

Shen Qi knows that in front of this life-saving problem, the real variable function and the Stitches integral, the Cayley transition matrix and the Weilstrass quadratic form, the hyperelliptic integral and the Abel's theorem...all advanced mathematics Formulas, theorems, and inferences are all invalid.

　　 This is a purely logical derivation question, which was voted as a threshold question by the leaders of 102 countries.

　　 It doesn't work if you bring any reference books. The most useful one should be the junior high school math textbook.

　　The necessary mathematical knowledge reserves are addition, subtraction, multiplication and division operations within 500, and simple linear equation solving methods.

　　 There are only two words left: brain power.

　　 The international rules seem to be different from the Chinese rules. Shen Qi didn't need to think about it and knew that their Chinese team leader must have voted against this threshold logic problem, but the minority obeyed the majority, and it was useless to vote against it.

　　 What Chinese students are strong at is model-based problem-solving, while internationally, the logical thinking ability of young people is more important.

　　 Shen Qi fell into contemplation, and came to the international arena to discover that it is not the esoteric theory that is not afraid of playing all over the world, but the nine-nine multiplication table and the simplest linear equation.

　　 He had some ideas, so he deduce three necessary conditions along the way, and listed a system of linear equations.

　　 Next, whether to score 7 points or -7 points, it depends on pure brain burning.
