Because of the disagreement of 5.68 pounds, Shen Qi, Zhou Yu'an and the cashier British girl were deadlocked.

This sparked a lot of discussion among the British crowd in line behind them.

"They are Orientals. ”

"Chinese?"

"Chinese have the best mathematics. ”

"The Chinese multiplication table is amazing. ”

The British crowd of onlookers were not disgusted with Shen Qi and Zhou Yu'an occupying the pit and not paying, but watched the excitement with interest, and in their minds, people who were good at mathematics were very good.

"Shen Qi, what should we do, will something happen to us? Forget it, let's give her 33.50 pounds and leave, scatter the wealth and avoid disaster. Zhou Yu'an was timid and retreated.

"Don't be anxious, don't panic, don't you see that these British people are praising us?" Shen Qi wanted to be calmer, he held the dual-currency credit card in his hand, and he couldn't bear it, so he swiped the card to pay 33.50 pounds, so as not to be beaten for a few pounds.

"She has no ill intentions, please don't get me wrong, two young gentlemen. Suddenly, an authentic South London accent sounded behind Shen Qi and Zhou Yu'an.

The two looked back, and an old white man with glasses looked at them with a smile.

The old Englishman's outward features were peculiar, his face was thin and long, his cheeks were sunken, as if he had been machined with a knife, his hooked nose was astonishingly sharp, and his ears were almost perpendicular to his cheeks at a right angle of nearly 90 degrees, which would have been a little scary if he hadn't been wearing a pair of gold-rimmed glasses.

“No，no。 Shen Qi waved his hand, indicating that we are all good citizens, not here to do things in the British Empire.

"Tesco is a world-famous supermarket chain, they don't deliberately deceive consumers, admittedly some of the discounted prices are miscalculated, I think this is an oversight of their financial manager, and it has nothing to do with this beautiful lady. ”

"The British are obviously not as good as the Chinese, and most of us cannot calculate addition, subtraction, multiplication and division within 20 without relying on calculators, for which we will lose about £800 million a year, and our Prime Minister has decided to import mathematics textbooks from China to improve the overall level of mathematics in the whole British people. The British old man looked at the cashier girl, then at Shen Qi and Zhou Yu'an, and explained. He was carrying a shopping basket and was also a guest.

Shen Qi, who is at level 1 English level, understood it halfway, and the old man probably meant that they British people are very poor at math and often make mistakes in accounting, so please forgive me from Chinese friends.

If you explain it like this, then I won't be angry, Shen Qi is no longer entangled in the loss of 5.68 pounds, he swiped the card and paid 33.50 pounds.

The cashier girl in the fog put the goods purchased by Shen Qi into the shopping bag, and Shen Qi took the shopping bag and prepared to evacuate.

"Perhaps I can compensate you for the loss of £5 and 68p by other means. The old Englishman said again.

"!" Shen Qi was shocked.

"What kind of groove?" Zhou Yu'an didn't know what to do.

"This weird old man can mentally calculate addition, subtraction, multiplication and division within 40, he is a local folk master! Strong dragon does not suppress the head snake, Zhou Yu'an, hurry, run!" Shen Qi ran away with his shopping bag.

Zhou Yu'an followed Shen Qi to the door of the supermarket, and the two of them gasped, and then walked slowly along Waterloo Avenue to enjoy the British scenery.

During the movement, Shen Qi, who couldn't bear the loneliness, stopped in front of the stall along the way, and he was attracted by the traditional British snack of fish and chips.

"Hey, Zhou Yu'an, let's buy some local snacks in London and try them. Shen Qi took out a £10 note and was greedy.

"Shen Qi, you are a foodie, you bought a bunch of food in the supermarket, and came out to buy food again! Fish and chips are hard to eat, I don't want to eat them, let's go." Zhou Yu'an dragged Shen Qi and wanted to pull Shen Qi away.

"It's your first time in the UK, how do you know that fish and chips are unpalatable?"

"Teacher New Oriental said. ”

"Do you understand the unity of knowledge and action, practice is the only criterion for testing all theories, Zhou Yu'an, you are a stingy ghost and are reluctant to spend money, I will invite you to eat." Boss...... Oh no, hey-man, fish-and-chips, two. Shen Qi handed the £10 bill to the roadside stall boy.

The British guy who sold fish and chips quickly wrapped two fish and chips, handed them to Shen Qi and Zhou Yu'an, and then found a five-pound bill and a bunch of coins.

Shen Qi glanced at the change that the British brother was looking for, one fish and chips was 2.3 pounds, two were 4.6 pounds, and he was looking for me for 8.6 pounds, what kind of god operation is this?

Is the mathematics of the British really scummy to such a point?

How much is 10 minus 4.6, Chinese primary school students can immediately give the correct answer.

Shen Qi returned 3.2 pounds to the British brother, and the stubborn Englishman was not happy, he insisted that he had not miscalculated.

"Zhou Yu'an, you testify to me that I am an honest person and did not deliberately defraud the British people of their money. ”

"Let's go, let's go, if you go with this Englishman, he may beat you. ”

With £8.6 in change, Shen Qi and Zhou Yu'an left the fish and chips roadside stall, and the two walked to the Thames River to find a bench to sit down and eat fish and chips.

"Newton was English, and he invented the integral. Shen Qi said.

Zhou Yu'an answered: "Green and Taylor are amazing British mathematicians, they invented the Green function and Taylor's formula, and they almost drove me crazy. ”

"And McLaughlin and Clem, McLaughlin series and Clem's law bothered me for a long time. ”

"Turing was also British, he was a mathematical genius. ”

"There have been so many outstanding mathematicians in British history, why is the mathematics of contemporary Britons so bad?"

"When my junior high school students come to the UK, they should be able to dominate the field of mathematics alone. ”

"So the UK is a great place to be. ”

"But seriously, Shen Qi, your English needs to be strengthened. ”

"That's true, fortunately, the IMO exam questions are translated into various Chinese, otherwise I may not be able to understand the questions." ”

Shen Qi and Zhou Yu'an returned to the hotel after a walk around the streets of London to prepare for the upcoming IMO race.

China has been the most powerful king in the International Olympiad in the past 30 years.

Since participating in the IMO for the first time in 1985, the Chinese Olympiad team has won 18 team championships, and the other countries called Dad.

Shen Qi: The Chinese Olympiad team came to the UK with only one purpose--- championship.

"Shen Qi, the overall level of mathematics in our Chinese is so powerful, primary school students can do addition, subtraction, multiplication and division within 100, while most adults in the UK cannot complete simple calculations within 20. It can be said that we have laid a very solid foundation in mathematics since childhood, but no Chinese has ever won a Fields Medal, and the British who have rotten mathematics like such a bird have won the Fields Medal six times. ”

Zhou Yu'an, lying on a single bed in a hotel room, added: "I mean Chinese whose nationality is China." Well, even with the addition of Yau Chengtong and Tao Zhexuan, only two Chinese have won the Fields Medal so far. ”

"I feel that my country's mathematics is similar to cycling, both of which are populous countries in this sport, and the mass base is extremely deep, but there are only a handful of top world-class athletes. On the other hand, in the UK, although most of them are weak chickens, once a few strong chickens emerge, they are world-class super strong chickens. I can't tell you why, maybe it's because of the different national conditions. After Shen Qi finished speaking, he went to the shower to take a shower, of course he knew that the Fields Medal awarded every four years was the highest achievement in mathematics, yes, why no Chinese had ever won the Fields Medal, this is not scientific.

On July 25, local time in the UK, the Chinese Olympiad team gathered at the hotel for a meeting.

The leader of the Chinese Olympiad team has been controlled by the British organizers, and the team is currently controlled by the deputy team leader.

In fact, the leaders of the Olympiad teams of all countries were controlled by the organizers, and they were arranged in a secret location, unable to communicate with the outside world.

For the sake of fair play, this rule has been in place since the first IMO was held in 1959 and continues to this day.

Team leaders from all over the country gathered together and each person came up with one to three questions, forming a question bank of nearly 300 questions. After several rounds of screening, the team leaders voted for the six questions with the highest number of votes as the six official competition questions of this year's IMO. And each of them is translated into the Chinese language for the organizer for the record. The competition papers obtained by the contestants from all over the world will be in their native language, so there is no language barrier in doing the questions.

It wasn't until the end of the competition that the team leaders were released. This mechanism guarantees fairness.

The team leader was locked up, and the deputy leader of the Chinese Olympiad team mobilized before the game: "In the past 30 International Olympiad competitions, our China has won 18 team championships, and we are the well-deserved overlord of this event. ”

"However, players and coaches, you must be clear that although our Chinese Olympiad team is strong as a whole, it is not invincible. ”

"We've lost and we've missed, we've lost to the United States, Russia and even South Korea, and that's a hard lesson. ”

"In this IMO, the above three teams are still the most difficult opponents on our road to the championship, especially some developed countries led by the United States, they advocate take-it-or-leave-it, they do not cultivate talents, they are the harvesters of talents. ”

"All in all, we must do our best, boys, do you have the courage!" said the deputy leader, suddenly impassioned.

"Yes!"

"There is no determination!"

"Yes!"

"Our goal?"

"Champion! Champion!"

Shen Qi, Zhou Yu'an, and Yu Lei went with me to participate in the pre-game announcement, and the rest of the players and coaches stayed in the hotel to prepare for tomorrow's IMO race. The deputy team leader left the hotel with three team members and walked to London South Bank University.

London's South Bank University auditorium was packed with representatives of Olympiad teams from 102 countries around the world.

On the rostrum sat a group of bigwigs, of all colors, who were well-known experts in the international mathematical community.

I would like to invite the head of the jury, Sir Andrew Wiles, a Fields Medalist, a Fellow of the Royal Society of London and a professor at the University of Oxford, to announce the rules of the competition. The moderator asked the head of the jury to read out the rules of the competition, which is a routine matter, and the teams from each country must be represented on the spot.

The leader of the judging panel, an old white man, stood up and the audience erupted in thunderous applause.

Fields Medal winner, Fellow of the Royal Society of London, Professor of Oxford University, and knight canonized by the Queen, these titles are too scary to set up in one person.

Professor Wiles, who had also been the head of --- Princeton's mathematics department, began to read out the rules of the competition. His most famous masterpiece that shocked the world was the successful proof of Fermat's Great Theorem in 1995.

After Princeton's tenure ended, Wiles returned to his native England to serve as a professor at his alma mater, Oxford Merton College.

"Lying in a big groove ......" Shen Qi and Zhou Yu'an in the audience were dumbfounded, the leader of the judging team, Sir Wiles, who was known as the scary man, had seen them, it was the old British man they met in the supermarket two days ago.
