You must know that the two problems that Shi Shouxin came up with were the second of the ultimate problems in ancient Chinese mathematics, but Wang Chen was able to solve them easily, which naturally caused them to be shocked.

In fact, it is not that ancient Chinese mathematics was underdeveloped.

On the contrary, ancient Chinese mathematics has always been well developed, at least until modern times, far ahead of Western countries.

It's just that there are several stages in the development of mathematics in China.

Not to mention the rest, the golden age was the Song and Yuan dynasties, and there were four mathematicians, known as the "Four Masters of the Song and Yuan Dynasties", namely Li Zhi, Qin Jiushao, Yang Hui and Zhu Shijie.

The writings of these four people pushed ancient Chinese mathematics to the highest peak.

Unfortunately, Li Zhi, who is closest to the present time, has not yet been born, and the solution of some mathematical problems is very complicated.

For example, Shi Shouxin just came up with two questions.

In the eyes of many modern people, hey, elementary school students can answer.

However, in the early days of the Northern Song Dynasty, it was not that no one could answer the two questions just now, and there were definitely some questions, but it was unheard of to be able to solve them as easily as Wang Chen.

Because he uses modern mathematical theories!

To put it mildly, if a person sorts out modern primary and junior high school mathematics and brings it to the Northern Song Dynasty, he is definitely the great master of the mathematics industry!

The two problems that Wang Chen solved were based on Sun Tzu's theorem, that is, the remainder theorem, and it was not until the appearance of the Southern Song Dynasty mathematician Qin Jiuzhao that it became easier to solve.

Zhao Kuangyin looked at Shi Shouxin, "Shi Shizhong, what else is there to ask?"

Shi Shouxin looked at Wang Chen in front of him and couldn't help but smile bitterly, he finally understood how awesome Wang Chen's mathematics was, but he didn't need to ask the third question, but when he saw a few old brothers who had placed heavy bets on him, he had to grit his teeth and said: "There is a third question, you must not be able to answer it." ”

Wang Chen thought he was still acting, and blinked and said, "Just let the horse come." ”

Gao Huaide, Wang Ming and others were nervous, their palms were full of sweat, each of them made a heavy bet, more than 2,000 yuan, less than 1,000 yuan, according to their salary, almost half a year!

Xue Juzheng and Shen Yilun were curious, curious about what problems Shi Shouxin would come up with, of course, they didn't doubt that Wang Chen would be able to solve them easily.

As for Wang Jien and Li Jilong, their eyebrows are already dancing, they have won two games in a row, can they not be happy?

Shi Shouxin had no way to retreat, so he had to say the ultimate mathematical problem, "A chicken is worth five dollars, a chicken mother is worth three dollars, three chicken chicks are worth one dollar, and you must buy all three kinds of chickens.

Zhao Kuangyin quipped: "Shi Shizhong, shouldn't there be no answer again?"

This time, Shi Shouxin said confidently: "Yes." ”

Xue Juzheng looked at Wang Chen, eager for knowledge: "Jinghai Hou, answer?"

Shen Yilun and other civil officials also pricked up their ears and listened carefully.

Wang Chen said lazily: "There are four chickens, eighteen hens, and seventy-eight chicks." ”

Hearing this, Shi Shouxin laughed, clapped his hands and said, "Jinghaihou, you still made a mistake. ”

Zhao Kuangyin asked, "Isn't the correct answer this?"

Xue Juzheng and the others have not yet calculated, and they also looked at the past at the same time.

"Of course not. Shi Shouxin said confidently: "Jinghaihou is still almost arithmetic." ”

Gao Huaide, Wang Ren and the others let out a long breath, they finally didn't have to lose money, they couldn't help but give Shi Shouxin a thumbs up, and said in their hearts that they had finally cured the arrogant boy.

But their joy had just been born, and Wang Chen pouted and said, "Do you want to say that there are eight chickens, eleven hens, and eighty-one chicks, or twelve chickens, four hens, and eighty-four chicks?"

Shi Shouxin snorted, his eyes widened and he didn't speak.

Shen Yilun was puzzled: "Why did Jinghaihou say three answers?"

Gao Huaide didn't know how to pretend to understand, and sneered: "Didn't Jinghaihou think that he could bump into it by saying a few more answers?" ”

Shi Shouxin said helplessly: "Jinghaihou has already said just now, there are eight chickens, eleven hens, and eighty-one chickens, but the old man doesn't understand why he said the other two answers." As he spoke, he looked at Zhao Kuangyin, "Your Majesty, Jinghaihou's answer is one of the three, count me as winning, or count him as winning?"

Zhao Kuangyin was a little embarrassed, and he didn't speak.

On the contrary, Wang Chen looked at everyone with a smile and made a calculation gesture at Xue Juzheng.

Xue Juzheng's eyes lit up, and he felt that he seemed to have comprehended something, so he immediately pulled Shen Yilun and the others to quickly reverse reason and calculate.

"Three middle schools and one ......" Zhao Kuangyin hesitated for a moment, and said to Wang Chen: "Jinghaihou, you can't rely on ...... for counting"

Before he finished speaking, Xue Juzheng exclaimed, "Oh my God!"

Zhao Kuangyin was a little unhappy when he was interrupted, and frowned: "How can Xue Xiang be amazed?"

Xue Juzheng said with a look of surprise: "The three answers that Jing Haihou said are all correct!"

Yes?

Three full pairs?

Shi Shouxin was stunned, let alone Gao Huaide and others.

Xue Juzheng, Shen Yilun and others respectively showed the three reverse reasoning processes to everyone.

Everyone laughed helplessly after reading it, and the eyes that looked at Wang Chen were completely different.

"It's not easy for ordinary people to get one of the answers to this kind of problem, but Jing Haihou actually got three?"

"Count, absolute count, Jinghaihou is really amazing, although I don't know how he calculated it, but if he guessed correctly, he should have used the method just now. ”

"Awesome!"

"Jinghai Hou is a math and a celestial!"

"Admiration, admiration, I can come up with three answers in such a short period of time, and it is not an exaggeration to say that Jinghai Hou is the first count of my Great Song Dynasty!"

"yes. ”

The other officials present couldn't help but marvel.

They were all shocked by Wang Chen's level of mathematics.

Gao Huaide, Wang Renzhan and other old brothers who supported Shi Shouxin's face became a little ugly in an instant, they had already imagined the situation of losing half a year!

Zhao Kuangyin, who saw that he was going to sit in the village to win money, laughed, clapped his hands and said, "Jinghaihou, it's good, it's really good." He smacked his lips, a little impatient, "Jinghai Hou, take out your arithmetic questions and ask Shi Shizhong, if he can't answer, even if you win." ”

Xue Juzheng also hurriedly took a look, "Jinghaihou's arithmetic questions must be very difficult, I really want to see it." ”

One of the middle-aged men in the official position said, "Jinghai Hou, hurry up and ask the question." ”

Wang Chen looked at Shi Shouxin, who was still acting, and pretended to be disdainful: "Shi Shizhong, don't say that I bullied you, I will make my debut later, and a five-year-old child can do it, but I don't know if you can answer it." ”

Can a five-year-old make it?

Everyone was a little disappointed, they originally wanted to see how difficult Wang Chen's question was, and then listen to the solution, but it seemed hopeless.

Shi Shouxin was also happy, "The question that a five-year-old child can do, is it possible that the old man can't do it?"

Zhao Kuangyin sighed, "Jinghaihou, you can't act like this, I'll sit in the village." ”

"Your Majesty, rest assured, I believe that Shi Shizhong will not be able to do it. Wang Chen smiled, and looked at the dozens of officials present, "And I don't think anyone present can do it." ”

Ha?

Do you think we're not even as good as five-year-olds?

Not only did Shi Shouxin believe it, but even Xue Juzheng, Shen Yilun and others didn't believe it, they felt that Wang Chen was talking big.

Shi Shouxin urged: "Come out, say it in advance, if a five-year-old can't do it, even if you lose." ”

"No problem. Wang Chen put his hands behind his back, raised his head at a forty-five degree angle and looked up at the sky, and said lightly: "There are three people who go to the inn and ask for a room, the house price is thirty Wen, and each of them pays ten Wen, but my Great Song Dynasty recovered Jiangnan Putian Tongqing, the store only needs twenty-five Wen, and the remaining five Wen He asked the shopkeeper to return it to the three, the shopkeeper was greedy for ink and two Wen, and then returned one penny to each of them, so that each of them only paid nine Wen, and the three of them had a total of 27 Wen, plus the two Wens of the shopkeeper's greed for ink were only 29 Wen, excuse me, where did the penny go?"

As soon as the question came out, everyone in the audience was stunned!

it!

yes, where did the penny go?

Isn't it twenty-nine twenty-seven yuan, plus the two pennies that the shopkeeper is greedy for? But Wang Chen just said very clearly, the three of them each contributed ten yuan, a total of 30 yuan, why did the money change hands and lose one penny?

Xue Juzheng was stunned.

Shi Shouxin's eyes were even darker.

The remaining Gao Huaide, Zhao Kuangyin, Wang Jien and others are even more frowning and racking their brains, why is there a penny missing?

Instead, Wang Chen looked at everyone with a smile and asked, "Does anyone have an answer?"

"Wait, I seem to be working out. "Shi Shouxin is a little unwilling, crazy calculating.

Xue Juzheng and others also held pens and paper and kept counting.

It's not right, three nine twenty-seven is right, plus two texts is indeed twenty-nine.

Wang Chen yawned.

Suddenly, Zhao Heng, the third son brought by Zhao Guangyi, whispered: "Daddy, the fifth brother said that Jinghaihou was deceiving. ”

Because everyone was quietly calculating, even if Zhao Heng's voice was small, he was still heard by everyone.

Zhao Kuangyin looked over curiously, "How to deceive people?"

Zhao Guangyi also looked at his fifth son, Zhao Yuanjie, who was only four years old, "Fifth brother?"

Wang Chen smiled, the question he came up with just now would be complicated as long as normal people, and children were as pure as snow, so they would naturally not be blinded.

Sure enough, Zhao Yuanjie, who looked very cute, snapped his fingers and said: "The store returned five texts, the three of them came out with twenty-five texts, the shopkeeper two were greedy for ink and two texts, and the actual three of them produced a total of twenty-eight texts, not twenty-seven texts." ”

Shi Shouxin was puzzled: "Why is it not twenty-seven, each of them has nine texts, three hundred and twenty-seven." ”

Zhao Yuanjie was too young to say clearly, so he pouted: "It's not twenty-seven, it's not twenty-seven, it's twenty-eight." ”

Everyone thought that the child was talking nonsense and was not ready to listen to it anymore.

Who knew that Wang Chen smiled and said: "King Jin, the fifth prince is quick to think, and he will definitely shine in the future." ”

"Hmm, what does Jinghaihou mean by this?" Zhao Kuangyin was puzzled: "Could it be that Yuan Jie answered correctly?"

"Yes. Wang Chen nodded.

Xue Juzheng frowned and said, "But it's not right, your topic is indeed three people who spent nine essays each." ”

"It's not. Wang Chen waved his hand and said: "Actually, this is a question that misleads your thinking, originally the money spent by the three people was thirty Wen, which is no problem, and then the store returned five Wen, in fact, after each of them got one Wen, it was three times nine, which is equal to twenty-seven Wen, and the shopkeeper was greedy for two Wen, plus the twenty-five Wen received by the store, isn't it exactly twenty-seven?"

Gao Huaide still didn't understand, "How can it be two pennies for the shopkeeper and twenty-five cents for the store?"

Wang Chen smiled: "The money spent is equal to the money that others get, right?"

"That's right. Gao Huaide nodded.

Wang Chen said again: "In this case, the three of them each spent nine texts, a total of twenty-seven texts, and returned three texts, doesn't it add up to exactly thirty texts?"

Everyone understood when they heard it, and they all felt the urge to vomit blood at this moment!

Only now do they understand how many grandsons Wang Chen has, and how strange the question just now is, it is simply that Nima is so strange that a monkey popped out of the stone on Huaguo Mountain!!

“……”

"Jing Haihou's hand ......"

"Sure enough, a five-year-old can make it!"

"We can't even compare to a five-year-old child? ”

"I can see that Jing Haihou is teasing us. ”

"Eh, that's not what I said, let me ask you, if Jinghai Hou is in charge of the three divisions, based on the arithmetic question just now, if you want to be greedy for ink, can you find out?"

"Ugh. ”

"No, you can't. ”

"That's it, Jinghai Hou, this is the subject of great wisdom and foolishness!"

"Yes, this question is not only an arithmetic problem, but also a test of people's thinking!"

Kneeled.

Everyone knelt down for Wang Chen.

They really don't know what to say, obviously looking at a simple topic that can't be simpler, but Wang Chen made it out and turned it into the ultimate problem that dozens of officials in the Northern Song Dynasty couldn't calculate!

You must know that there are many people present who are the most learned people in the world in the eyes of others, such as Xue Juzheng, Shen Yilun and others, as well as Hanlin Bachelors and so on, but none of them have answered such a simple question.

couldn't help it, Prime Minister Xue Juzheng shook his head with a wry smile and said: " After listening to the questions and answers of the Marquis of Jinghai, I knew that his attainments in arithmetic had already reached the pinnacle, if he was willing to compile arithmetic books, it would definitely be a treasure of my arithmetic world in the Great Song Dynasty, and he taught us a lesson on this topic, Your Majesty, the minister felt that he should let the Marquis of Jinghai be the doctor of the prince of the country, and teach me the children of officials of the Great Song Dynasty, so that the arithmetic of my dynasty will surpass any dynasty in history, and the Marquis of Jinghai will definitely bring me to a peak of arithmetic!"

Dr. Guozijian is the official in charge of teaching in Guozijian.

In the early Song Dynasty, the number of Guozijian students was very small, and only the children of officials above the seventh grade were accepted.

You must know that in China, children's learning has always been the most concerned thing for adults, and in the ancient etiquette, the status of the teacher is second only to the emperor and the parent, you can imagine how noble the status is, and the teacher is also the most respected profession.

There is a saying: One day is a teacher, and one life is a father.

If Wang Chen can really become Dr. Guozijian, then it is equivalent to having countless more "sons" with strong family backgrounds, and the benefits will definitely be indispensable anyway.

It's just that Dr. Guozijian is a really talented and wealthy Confucian, and I don't know if Zhao Kuangyin will agree, Wang Chen looked at it a little expectantly, he still hopes to become Dr. Guozijian in his heart, but he will eventually return to Jinghai to engage in electric energy, so he is not sure if Lao Zhao can agree with Xue Juzheng's opinion.
