Jiang You was talking to the two old men, and when he saw Su Yi looking over, he immediately nodded and smiled. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

He said a few words to the two old men, and then took them to greet Su Yi.

Mr. Wan Haotong has lived in Sushui County for a long time, and has won the first prize of the local mathematics gentlemen's association for 17 times in 20 years, while Mr. Fu Ping has traveled to various cities and villages, participated in gatherings in various places, and has won more than a dozen first prizes, and has won countless mathematics awards. Jiang You introduced.

"Mr. Wan, Mr. Fu. Su Yi saluted respectfully.

The two old men smiled and nodded.

Wan Lao said: "I have heard Su Xiaoyou's ten famous for a long time, in the previous archery competition, you can let me wait for the old man to open his eyes!"

Su Yi smiled, and then heard Fu Lao Fu stroke and smiled: "Indeed, I have never seen an archery genius like Su Xiaoyou in my life;

"Fu Lao said seriously, if the capable person deliberately gives way to the offspring, it is a contempt for the offspring, can the competition still be called a competition? And the little student also wants to see what is the beauty of the second realm of mathematics!" Su Yi said.

The second elder nodded, with a look of appreciation.

Seeing this, Jiang You's eyes flashed with a different color.

"Su Shichou, you said the same thing a while ago, and the result was that the second realm of archery was directly revealed to crush all the contestants, and you said this again this time, could it be that you have hidden some hole cards?" Jiang You said curiously.

When the two old men heard this, the corners of their mouths twitched.

Since Jiang You did not deliberately lower his voice, the people around him all held their breath and listened with their ears pricked up, expressing their curiosity about this.

Even Zhou Caichen vaguely heard it, looked at Su Yi, and squinted slightly.

"Ahem, Brother Jiang laughed, he hadn't studied mathematics since he was a child, and he never reached any of them. Su Yi said honestly.

Everyone breathed a sigh of relief, the sixteen-year-old archery second realm was already enough, if Su Yi could still be proficient in mathematics and reach the realm, then no one's heart would be able to stand it.

Zhou Caichen seemed to be secretly relieved.

"Young master, it seems that the information investigated by the master is not wrong, then Su Yi has never been exposed to mathematics, and it is definitely impossible to defeat all the arithmetic masters present. An attendant behind him said.

"Don't talk too much, there are many prodigies in history who are born proficient in arithmetic, and never judge the result until the end. Zhou Caichen said solemnly.

The attendant hurriedly said yes.

But no one noticed that there was a faint hint of smugness floating between Zhou Caichen's eyebrows, and no one knew what he really thought in his heart.

"Brother Cailiang has been learning mathematics since Mengxue, even with his talent, he only reached the second realm of mathematics when he was an adult, you Su Yi is just a humble scholar, what number can you calculate? Today, I definitely want you to die here and complete your father's great cause!"

Zhou Caichen's eyes were like torches.

After Su Yi and the second elder finished greetings, Xin Lao began to announce the rules of the math competition.

Next, all the more than 100 gentlemen who participated in the competition will each board a single boat in the river to answer the math problem, the competition is carried out in the form of a time limit to answer the question, the first person who answers each question correctly will get 50 points, the second and third place will each get 30 points, 200 points, and the others who answer correctly within 200 breaths will each get 10 points, and the total score will be calculated at the end of the ranking.

Of course, since it is answered in the river, there will definitely be a more exciting way to play, Xin Lao sold a pass here, and mysteriously said, "You will know when you answer the question", which attracted everyone's claws and curiosity.

Xin Lao smiled, raised the yellow paper in his hand, and once again turned into a streamer and flew towards the Wu Temple.

Su Yi saw that there was golden energy blowing on the surface of the river, as if he had uncovered a picture scroll, and in an instant, hundreds of flat boats appeared in everyone's field of vision, making him look amazed.

There is still a golden list in the sky over the other side, and all of them have a zero word after their name.

The contestants stepped onto the platform and boarded the boats.

These flat boats are only one person long and one arm wide, and can only accommodate one or two people, so Su Yi picked a flat boat at random and sat on the seat.

Suddenly, the boat under the seat was free of pulp and took Su Yi to the middle of the river.

At this time, Su Yi looked down and saw that a small desk in front of her was placed with pen, ink, paper and inkstone, which was obviously used by the contestants to answer the questions.

While grinding ink, Su Yi looked around, and found that all the contestants' hundred-leaf flat boats had also automatically sailed to the center of the river, each boat was about five feet apart, and this section of the river was filled in a disorderly manner.

The people around smiled at Su Yi one after another, and Su Yi responded one by one.

"I don't know what math problems will come up with? I hope it's not too difficult, and my math grades in my previous life weren't particularly top-notch. Su Yi thought to herself.

At this time, the gong sounded, and Su Yi picked up the brush.

The spectators on the riverbank unanimously chose to be quiet, a competition that required concentration and mental use, and there was no room for noise.

And Xin Lao also quipped: "Don't be nervous, gentlemen, it's okay now, just to have a good time, if you miscalculate when doing business, you will lose money!"

Everyone on the river laughed, and the previously dull atmosphere was swept away.

Then, Xin Lao took out a piece of paper and began to recite the question.

Su Yi just smiled when she heard it.

Just listen to Xin Lao's recitation:

Three of the thousand and five soldiers were killed in battle, and the Chu army was forced to cry.

King Qi hurriedly put the queue on the line, and Han Xin ordered the army to be at ease.

the list of seven and seven, the remaining six, the list of five and five, and the view of four people;

There are two more people in the queue in three or three, how many Han soldiers are there?

This is the most famous "Han Xin Point Soldier" math problem in the Bingfeng Continent, and the allusion comes from a folk tale of Han Xin.

Legend has it that in the early days of Han Xin's assistance to Liu Bang, he once traveled with a small number of soldiers and suddenly encountered the Chu army, and a skirmish broke out between the two sides.

Han Xin did not intend to pursue deeply, and also reorganized his troops and horses to return to the camp, and when he reached a hillside, the scouts suddenly reported that the cavalry of the Chu army was chasing him.

Han Xin climbed the hillside, and sure enough, he found that the dust was flying in the distance, and the sound of killing shook the sky, and the Han army was tired and saw the pursuers coming, and everyone was panicked.

Han Xin took a closer look and found that the number of chasing soldiers of the Chu army was far inferior to his own, so he quickly ordered the troops, first lined up all the soldiers in a column of three people, and then ordered the soldiers to line up in a column of five people, and finally let all the soldiers line up in a column of seven people, and quickly calculated the number of the whole army of his own side according to the extra number of people in each queue.

The soldiers found that their own number was much larger than that of the Chu army, so their confidence doubled and they bravely met the enemy, and sure enough, the Chu army was defeated at the first touch.

Later generations quoted this allusion from Han Xin's soldiers to make a math problem, but the number on the question was different each time, so there was no fixed answer.

At this time, Han Xin ordered the soldiers, the first sentence gave the approximate range of the number of Han troops, the next three sentences were allusions, and the last four sentences were the real problems.

The meaning of the first sentence is: 1,500 soldiers died in battle, that is, about 1,000 and 50 soldiers remained. And the meaning of the last four sentences is: when the soldiers are lined up in a line of seven, there will be six more people, four more in a five-person lineup, and two more people in a three-person lineup, asking for the number of Han troops...... There are many answers, but the answer must be the one closest to the number of one thousand and fifty. Su Yi thought to herself.

"Bingfeng Continent does not yet have the calculation method of 'Han Xindian', so I can only take some final numbers at will and remove them one by one until a certain number meets the requirements of the question; this stupid method is not enough for people like me who have no mathematical realm, I am afraid that the tea time will not be exhausted; but fortunately, later generations of mathematicians have summed up the calculation method of the 'residual theorem', which I can directly quote. ”

At this moment, a low exclamation sounded from the embankment.

Su Yi turned his head to look and found that when some people around him were immersed in calculations, smoke rose faintly several feet high above their heads, among which countless black numbers rose flutteringly, ranging from one to ten thousand, and so on.

The two old men Wan and Fu Lao before, as well as several other old men, even closed their eyes, these people seemed to be closing their eyes to recuperate, but in fact, a black shadow as thick as ink floated on their bodies!

These ink shadows poked out their fingers and kept scratching in the air, so fast that Su Yi couldn't even see their movements.

And with the swipe of the phantom fingers, one after another the black formulas of strange words appeared in the air, and quickly disappeared.

In just the blink of an eye, Su Yi saw twenty or thirty formula reincarnations, which were so fast that they were elusive.

"Isn't this an anomaly in the first and second realms of mathematics? Su Yi's eyelids jumped slightly.

The audience was also talking.

"Look, these 'digital smokes' and 'ink shadows' are mathematical anomalies?" said one of the contestants, pointing to the middle of the river.

"That's right, the digital smoke anomaly produced by the 'number in the heart' of the first realm of mathematics shows that this person is doing mental arithmetic, and can make his own numbers in the training ground without relying on pen, ink, paper and inkstone, and the calculation is more convenient; while the second realm of mathematics is 'countless', and it can even speed up mental arithmetic by ten or even a hundred times, which can greatly save time at critical moments.

The crowd was amazed.

"Oh my God, can mathematics speed up by a hundred times when it reaches the second realm? Isn't it possible to speed up the calculation by ten million times if it reaches the third realm?"

"You take it for granted, the average person's second realm can only be accelerated by ten times, and only mathematics in a higher realm can speed up the calculation speed by a hundred times, which is enough for people to calculate the result in an instant, what is the effect of speeding it up a thousand times and ten thousand times?"
