The Legend of Yuan Yao in the Three Kingdoms

Yuan Yao once thought that this mathematics was also included in the category of strange and obscene skills. It was not until this era that he realized that the status of arithmetic is not low.

At least the Confucian regime recognized the existence of mathematics.

The Taixue of the Han Dynasty even had a mathematics hall.

However, although the status is not low, it is not mainstream.

Therefore, although the development of arithmetic is good, strictly speaking, there is really only arithmetic but no mathematics.

But it is already very awesome.

After reading "Nine Chapters of Arithmetic", Yuan Yao found that the algorithm is so detailed and extensive that he never expected it.

It is said that he has already started to use the elimination method when solving linear equations, which has already surprised Yuan Yao.

And when Yuan Yao saw the algebraization of geometry involved, and even the idea of ​​infinite division, he was completely numb.

I almost yelled in my heart: "Those time travels are all nonsense. If you get a quadratic equation in one yuan, you will be astonished. I guess people will treat you as an idiot!"

There are some things that have to be seen with your own eyes to be true!

It's just that the awesomeness is the awesomeness, and the shortcomings are also obvious.

Compared with the giant work "Elements of Geometry" that grew up on the land in the west at almost the same time, Yuan Yao has never found rigorous axioms and postulates in "Nine Chapters of Arithmetic", let alone using strict logical proofs under the axiom system to derive the theorem.

All algorithms are derived for the purpose of solving practical problems.

There are benefits to this of course.

Pay attention to its practicality, the solution to a certain type of specific problem or the induction of a certain type of law can make people calculate faster and better.Everything serves the people and the king as its purpose.

But there are also disadvantages.

There is no strict logical proof, so that although many laws are summarized, the deeper aesthetic and philosophical value behind these laws cannot be found.

In Yuan Yao's heart, the top mathematicians should explore more in the vast field behind the algorithm.

It's a pity that in China, it will take another thousand years to have this awareness.

Of course Yuan Yao wanted to change the world, and it was not in vain for him to travel through it.

Not only to change the fate of Yuan Shu and the Yuan family, but also to change the direction of the whole world.

It's just that he was busy with saving his life before, so he really didn't have the leisure time to deal with these "non-business" things.

But now, after seeing a person who is interested in arithmetic very rarely, Yuan Yao's heart to influence the world has finally begun to sprout!

Guanglong is naturally Pang Tong's pseudonym.

These days, it is too common to only know the name but not the person.

And Pang Tong came here only to satisfy his own curiosity.

Let's see how this young master of the Yuan family who is in the limelight and has some eccentricities is like!

He only knew that Yuan Yao was also looking for himself, and he had heard a lot about Yuan Yao's deeds, and he was afraid that he would not be able to leave once he came, so he came here under the pseudonym Guanglong.

What's more, I thought that Yuan Yao would never think of his unpopular knowledge of arithmetic and didn't want to listen to what he said, but Yuan Yao's eyes almost lit up as if he saw a treasure.

Then I saw that Yuan Yao dragged himself to the case, pushed away the documents on the case, and then took a pen and ink, and unexpectedly came up with an arithmetic problem on the spot!

When Pang Tong came, he thought about many scenarios, but he never thought that he could come up with a question on the spot.

Yuan Yao was also really blunt, and came up with an enlightenment arithmetic problem.

Said: "Today, there are a total of purchases. People buy eight, the surplus is three, people buy seven, and less than four. Ask people, how many things are there?"

This is just a simple equation, and Yuan Yao really didn't want to make it too difficult, so as not to frighten Guanglong all at once.

It's really for the sake of caring for talents, so I'm so heartbroken!

However, with such a simple question, Pang Tong couldn't help it.

But seeing that he only saw it twice, he made some calculations in his heart, just swiped his brush and ink, and immediately wrote down the answer.

It's just writing and writing, and I can't help but feel a little weird.

"I came to Jiangling by myself, it seems that this is not what I did!"

Seeing that Guanglong wrote so quickly and answered very accurately, Yuan Yao immediately changed to a piece of silk without asking how he did the calculation.

It's just that the hand that raised the pen hesitated a little.

"What should be the question?"

"Geometry? Probability?"

After hesitating for a while, he looked at the young man and finally wrote: "Today there is a drunkard who lives alone in Lujiang. Nine out of ten days he will go to a wine shop to drink and have fun, and another day he will have a rest at home."

"His father deeply felt his evil, so he rushed from other places, hoping to catch him and return home with the wine shop."

"However, there are three places that the alcoholic goes to every day, and the probability of going is equal."

"His father couldn't find the two wine shops before he went, but what is the probability that he can catch him and the third wine shop?"

Seeing Yuan Yao write down the question in one fell swoop, Pang Tong was also a little dazed.

If the previous question is somewhat similar to the "Insufficiency of Prosperity" in "Nine Chapters of Arithmetic", this question of probability is really unheard of.

It seems simple at first glance, but it is not easy to take a closer look.

"More importantly, why did Yuan Yao come up with this question?"

What's more, looking at Yuan Yao's appearance, it is obvious that he has a well-thought-out plan, and he knew the answer in advance, and he is studying himself.

The image of the Yuan family son in Pang Tong's mind became more and more mysterious and weird.

"It's just that I really didn't come to learn arithmetic!"

Although Pang Tong thought so in his heart, he was also attracted by Yuan Yao's question, and couldn't help thinking about it.

The room fell silent for a moment.

Yuan Yao over there is also worried!

Worried that Guanglong would be stumped by this probability problem, thinking that he was embarrassing him, he retreated.

This will not work!

Seeing that he was silent, he quickly said: "There is no need to be anxious about Wen Ju, just stay here and study slowly."

Pang Tong never thought of this. He changed his name and method, but he couldn't escape the shackles of fate.

I wanted to refuse, but felt that I could learn something here.

Learn something... completely different.

Yuan Yao couldn't let this hesitation go.

Although the name of Guanglong has never been heard of, after all, arithmetic is not valued these days. Perhaps this person was submerged in the crowd in the original history.

After all, no matter how Guanglong reacted, he asked someone to arrange a place to live, and asked him to take the square silk cloth and go down to study it by himself.

Poor Pang Shiyuan, who came to Jiangling incognito, found that he was not found, but somehow fell into the ocean of arithmetic.

And Yuan Yao is even more so.

To let him know that Guanglong is Pang Tong, the silk must be torn directly.

What kind of mathematician should a good counselor be?

It's a pity that Yuan Yao is still looking for Pang Tong with his head covered, not knowing at all that he has been fooled into doing math problems by himself.

Chapter 233 Conquering Pang Tong with Thousand Years of Knowledge

Yuan Yao still attaches great importance to Guanglong.

After all, they are scarce talents, so they still need to be taken care of!

What's more, in Yuan Yao's mind, mathematics really requires talent.

This is not only true a thousand years ago, but also a thousand years later.

Therefore, whenever Yuan Yao has free time, he will go to see Guangwenju, care about his life as a mathematician, and also investigate whether he has talent or not.

And Pang Tong was almost tormented to death by the question that Yuan Yao came up with out of nowhere.

Originally holding the silk cloth, I didn't want to think about this inexplicable question, but I couldn't move my eyes when I put it on it.

When Yuan Yao saw Guanglong, his eyes were slightly red, his hair was a little messy, and he was thinking directly on the case with a pen and ink.

He was obviously a handsome young man, but he couldn't taste the slightest aura of handsomeness at this meeting.

Seeing this, Yuan Yao shouted in his heart: "This is the taste!"

"I went astray back then, isn't that what I looked like!"

Not daring to interrupt casually, Yuan Yao tiptoed a few steps closer, looked at it, but saw that the case was already densely written.

Just as he was about to speak, he heard Guanglong muttering to himself: "Although this question seems easy, there are many subtleties in it, and the probability is mentioned, it seems that it can be used in many places."

Yuan Yao felt something different when he heard it, and he thought to himself that Guanglong was quick enough to respond and strong enough to accept.

Probability and statistics are of course very useful knowledge, especially after the establishment of mathematical models, it can avoid risks and help decision-making in various fields.

Yuan Yao didn't expect Guanglong to be like a leopard in a pipe in a small question, peeking into some doorways.

The eagerness in this heart became even stronger, and he called out softly: "Can I get something from Wen Ju?"

Hearing this, Pang Tong turned his head and looked at Yuan Yao's cautious expression. He couldn't help but move slightly, but he still held back, stepped away, pointed to the densely packed characters on the case, and asked for advice: "Mr. Is this answer correct?"

Although there are no Arabic numerals these days, the ancients were not stupid, and they also had numeral symbols.

Now this number symbol is called Jusuan, and gradually evolved into Suzhou code in the future, which is not much more troublesome to write than Arabic numerals.

But Yuan Yao looked at it with his eyes, didn't pay much attention to the derivation process, but saw Guanglong's answer at a glance.

Three out of four.

Completely correct!

Now it was Yuan Yao's turn to be surprised.

Shame on the traversers!

I didn't expect that an unknown ancient man would be able to answer this question.

In fact, although there are many solutions to this question, Yuan Yao really did not expect that Guanglong could answer it so accurately.

Immediately praised: "That's right, Wenju is really extraordinary, so smart, really talented!"

Pang Tong saw Yuan Yao's fierce boasting to him, especially the joyful expression on his face, he just sighed: "It's nothing more than an arithmetic operation, why should you be so happy, my lord."

But I heard Yuan Yao say: "You can't say that, such a problem is really not easy to solve. Wenju is so easy, why don't you make me happy!"

After Yuan Yao finished speaking, he didn't intend to let Pang Tong be idle, so he grabbed his pen and ink and wanted to write a new question.

Pang Tongtong at the side saw that Yuan Yao was coming again, he had been tortured for several days, how could he not stop it.

He hastily stopped Yuan Yao and said: "Young Master Yuan's profound attainments in arithmetic, I already know, so there is no need to ask me any more questions."

Yuan Yao was deeply afraid of being misunderstood, so he quickly explained: "Wen Ju must not be misunderstood, it is only to make things difficult for Wen Ju, it is really hard to bear seeing a great talent like you."

Pang Tong saw that Yuan Yao treated people so sincerely, and suddenly felt a little guilty about his practice of anonymity.

He wanted to report his family name, but he asked, "Young master, why did you study arithmetic so thoroughly? It seems that you really value arithmetic."

Yuan Yaona really thought that what he was facing was an unknown mathematics genius, so he naturally responded sincerely: "Mathematics is not something illusory, it can be used for the construction of buildings, and water conservancy projects are actually beneficial to the country. The study of benefiting the people."

"If a certification system can be formed, it will be passed on for thousands of years and benefit future generations!"

Pang Tong saw a trace of enthusiasm in Yuan Yao's eyes.

Although he didn't understand why a child from an aristocratic family would be so proficient in such an unpopular knowledge of arithmetic, he still saw Yuan Yao's sincerity.

Moreover, the certification system he mentioned seems to be a brand-new statement.

Seeing that Guanglong didn't speak, Yuan Yao thought it was because his words were not strong enough, so he simply started writing.

Pang Tong didn't stop this meeting anymore, he just watched Yuan Yao write a paragraph of ghost-like talisman

Well, Pang Tong really didn't understand what Yuan Yao wrote, but even though he couldn't understand it, he could still feel that Yuan Yaofei was scribbling at will, and there was indeed some logic in it.

After a long while, I saw Yuan Yao pointing to the completed "great work" and said to himself: "Although the method of writing is correct, it is not systematic. If this method can solve this problem, then we will meet again in the future. You will have to think about it again.”

"However, if we find a certified solution and turn it into an axiom, then it will be a method that everyone in the world can directly use in the future, and no one will question it."
