A layman looks at the fun, an expert looks at the door.
Human life is inseparable from digital calculations.
Originally, people couldn't write "one, twenty, three, four, five", and it was difficult to calculate when the number was large.
1, 2, 3, 4, and 5 do not have this kind of trouble. Adults with mature brains can easily master the addition, subtraction, multiplication and division of two or three digits as long as they spend some time.
The popularization of Chinese numerals has brought great convenience to people's lives.
But that’s all…
But for an insider like Hurasd, the feeling is quite different.
Hulasd is a famous scholar in the West. He has been exposed to Western mathematical theories and can see the value and meaning behind these simple numbers at a glance.
The combination of these simple numbers can be infinite, simple and true.
In their Western mathematics, a test question needs to be recorded on a piece of paper or several pieces of parchment, but it can be incorporated into this Chinese numeral, which is a simple formula.
First go from simple to complex, then you can go from complex to simple.
Mathematics can only be developed in depth step by step if the basics of mathematics are simpler.
This book of mathematical enlightenment contains great wisdom in Hurasd's eyes.
Li Congde stood aside impatiently, while Hulasd pulled the bookstall vendor and asked questions.
Seeing that the bookstall vendor was impatient, Hulasd very kindly bought one copy of all the books on the bookstall.
The bookstall hawker became energetic and said: "I haven't read much, and I don't know much about college. I still know some basic skills in doing business. You may ask, but I will tell you everything I know."
Hulasd asked all the way through "Enlightenment of Arithmetic", asking about basic multiplication and basic division.
Hulasd knew all these simple things, but he didn't know how to express them using Chinese numerals.
He has a deep foundation in magic. As long as the bookstall vendor briefly describes a use, Hulasd can understand its meaning and can't help but be amazed.
Until the last page, the multiplication table.
Hulasd was astonished when he listened to the bookstall vendor's explanation.
The bookstall vendor was a little speechless. He also saw that the "old man" in front of him was not an illiterate who didn't understand anything. He just didn't understand the Chinese numbers promulgated by the imperial court.
But the multiplication table is from the Spring and Autumn Period and the Warring States Period, so what’s the fuss about it?
Could it be that there is no such thing in the West?
Hurasd held the book in his hand as if he had found a treasure, with only one thought in his mind: He must find a way to come to the Central Plains to study.
Most Baoshu Kings are highly respected scholars. Their mission is to study and influence believers with their knowledge, and they do not need to participate in preaching.
Studying knowledge is the greatest contribution to their sect.
After reading a book called "Shu Shu Enlightenment", Hulasid obviously still had more to say.
The bookstall vendor felt a little sorry. It was common in business to cheat outsiders.
Hulasd was dressed gorgeously, and he looked like a wealthy man.
The bookstall vendor offered a very high price and made a lot of money. When he saw this, he said: "I am just a small vendor, and I only know so much. If you really want to know something profound, you can go to the Mathematical and Physics Museum. This book "Magical Numbers"
"Enlightenment" was compiled by Chu Yan, the great scholar of the Institute of Mathematics and Physics, at the request of His Majesty... When it comes to arithmetic, there are few people in the Central Plains who can compare with him."
Hulasd loved magic and was itchy. After asking about the whereabouts of the Taishi Bureau, he looked at Li Congde and said: "If the prince feels bored, you can go back first. If you leave the Central Plains this time, I'm afraid it will be difficult to come here again in this life."
Bianjing, if you don't communicate well with scholars from the Central Plains, I will have trouble sleeping and eating."
Li Congde was originally impatient, but after hearing what Hulasd said, he felt happy and responded: "Let's go together, let's go together. I have admired the culture of the Central Plains for a long time."
There was a hint of sarcasm in the corner of Hulasd's eyes, but it disappeared in the blink of an eye.
Following the direction given by the bookstall vendor, Hulasid asked two more people along the way and found the location of the Wenli Pavilion.
Although numerology is one of the six arts, it is ultimately the same as shooting and is at the bottom of the six arts and is not valued by people.
Therefore, before Luo Yu's new dynasty, magic numbers were generally connected with Taishi Bureau.
Because the astronomical calendar requires calculations, most astronomical and calendar experts are good at arithmetic.
Before science was fully developed, the status of arithmetic was not high.
When Luo Youdu promoted Chinese numerals, he transferred Chu Yan from the Taishi Bureau, specially found an abandoned guild hall, and established the Mathematics and Physics Museum to promote mathematics.
Looking at the solemn and solid guild hall in front of him, Hulasd revealed his identity and asked to see Chu Yan with a scholarly attitude.
After Chu Yan learned Chinese numerals from Luo Youdu, he spent all his time combining numbers with Chinese arithmetic classics of all ages to study logical laws and arithmetic formulas. He was originally a master of arithmetic, and with Luo Youdu's full support, he used Chinese numerals as the basis to assist all directions.
He collected Shushu books and studied knowledge with a group of bachelors. He has achieved great achievements, and his level is far better than that of himself at the same time in history.

Faced with Hurasd's visit, Chu Yan did not hide his secrets and also invited Liu Yao, Zhou Jie, Zhou Maoyuan, and Hu Wanqing to conduct academic discussions with them.
Many of Hurasd's Western theories impressed Chu Yan and others. Although they were novel and unique, they were not beyond his understanding.
However, Chu Yan's research results derived from Chinese numerals over the years far exceeded Hurasd's knowledge of arithmetic.
Hurasd was so shocked by the profound theory that he knelt down to worship him on the spot.
Luo Youdu himself didn't know it, but he was actually under his influence. With the promotion of Chinese numerals, under the research of Chu Yan, a bachelor of mathematics and physics, and Liu Yao, Zhou Jie, Zhou Maoyuan, Hu Wanqing and others, they cooperated with the legacy of the ancients.
The accumulated experience and insights have gradually made up for the shortcomings of my own existence through my own efforts.
Hurasd originally wanted to stay in China for Manichaeism, but now he only has one idea: to be a good student and learn the mysterious and profound Eastern culture.
Luo Youdu later met with Li Congde and Hulasd twice symbolically.
Having made up his mind to wait and see the outcome, Luo Youdu expressed his attitude regretfully, just like the words of the Goryeo envoy.
"The imperial court has been on campaign for days and there is a serious shortage of food and grass. We have to work hard to carry out the expedition, but we are unable to cope with it. If your country can be responsible for all the military pay and food for our army on the expedition, I will be obliged to do so."
Li Congde was secretly happy in his heart, but his face showed great embarrassment. He said with a grimace: "The small country of Khotan is unable to support the Central Plains army."
Luo Youdu said: "Just let your Majesty wait for me for a few years. I don't expect the Kara Khanate to dare to attack Khotan immediately. You should make preparations to defend against the enemy first. As long as I regain my strength and he comes to fight, I will never tolerate it."
Li Congde was completely dumbfounded. He wanted to attack, not defend.
Luo Youdu continued: "If the Kara Khanate invades Khotan during this period, I will order the Xichuan Uighurs and the rebels to temporarily send troops to help."
He expected that Li Shengtian in Khotan would not sit still and wait for death, but would look for opportunities to attack the Kara Khanate.
As for whether the Guiyi Army will send troops to support Li Shengtian when he attacks the Kara Khanate, we have to wait and see...
