"How so?"

Shen Kuo walked back and forth in the room, his eyes shining brightly.

Shen Kuo never thought that he would be excited or even shocked by some mathematical knowledge that he had already mastered and was as easy as eating and drinking.

"Do you really get it?"

"No, not at all!"

Shen Kuo muttered to himself, of course he knew the reason, he Shen Kuo had already mastered all the knowledge here, and even thought that everything was too simple, but that kind of mastery was like mastering the pronunciation of the text with old-fashioned phonetics, not mastering it with the new 'Hanyu Pinyin'.

"This book of "Mathematics" is the 'Hanyu Pinyin' in arithmetic. Shen Kuo's eyes were shining, as a true thinker, of course he couldn't just look at the calculations on the surface of this "Mathematics", he thought more and further, but the more he thought about it, the more he found the benefits of this "Mathematics" for advanced and future mathematical communication.

"If I had studied this math book as a child, I would have spent at least ten times less time on arithmetic......

When Shen Kuo was thinking about this "Mathematics", many people in the martial arts world were also watching this "Mathematics", which was highly valued by Qin Xianao, and even put it after "Language".

"Why?"

"There is nothing surprising about this "Mathematics", why Qin Xianao put it after "Language". Lu Xichun frowned slightly.

The Qin Dynasty launched enlightenment textbooks this time, and there was a general rule, that is, one was more important than the other, and when the "Language" was launched, it was even said that the first three books were not qualified to be enlightenment textbooks.

This "Mathematics", Qin Dynasty did not boast too much in the newspaper, and only said that this "Mathematics" was finalized at one time. It will not be revised again in the future in any case.

What does this mean, how could Lu Xichun not know that this "Mathematics" is what Qin Xianao is most satisfied with, thinking that it has reached the extreme of perfection, so there is no need to revise it, and the evaluation is already extremely high.

"The content is simple. It's so simple that it's unbelievable, this is what he thinks is the highest level of enlightenment arithmetic textbook?" Lu Xichun shook his head lightly, "It's simple, it's verbose, it's super verbose, it's super verbose, it's some integers, factors, laws, definitions, etc., isn't this a snake to add to it, children need to learn these meaningless definition theorems......"

At this time—

"Alas!" a long sigh rang out.

"Father?" Lu Xichun looked to the side, and next to him, Lu Gongzhu slowly closed the "Mathematics" in his hand. His eyes glanced at Lu Xichun lightly.

"If Qin Xianao's "Mathematics" is not good, it is by no means what you call verbose and verbose, it is extremely simple. Lu Gongzhu said lightly, "But I don't understand, why does Qin Xianao attach so much importance to this arithmetic?"

"Important?"

"That's right, the reason why he Qin Xianao made it so simple and explained everything thoroughly, it was a fool who used this textbook to teach. I can learn something more or less. Lu Gong said in a deep voice, "Why is it verbose." Why simple, why verbose, you can't just look at the surface, you have to look at the depth, it's not simple, it's not verbose. ”

"What's that?"

It is the definitions, laws, formulas, and so on that are systematized, standardized, and refined in mathematics in the manner of "Instrumental Theory". Lu Gong said in a deep voice.

"But isn't this a snake to add to it?" Lu Xichun was not convinced.

"Ignorance!" Lu Gong shouted. "As before, a hammer in the east and a hammer in the west are called trouble. If you think about Hanyu Pinyin, Hanyu Pinyin is nothing more than the current phonetic pronunciation and refinement. Then you can make phonemes, and this is the existing arithmetic refinement, and this thing is made. ”

"What?" Lu Xichun's eyes widened.

"How easy is it to record and compose music by refining the five tones and twelve rhythms, and how easy is Hanyu Pinyin to make the phonetics?" said Lu Gong in a deep voice.

Lu Xichun frowned slightly.

Chinese Pinyin?

A flash of surprise flashed in his eyes: "I see, I understand, my father is still smart!"

"Gao Ming?" Lu Gongzhu sneered and shook his head, "It's not that I'm smart, but I read Qin Xianao's "Theory of Tools", read "Geometry Originals", read "Principles of Ethics", and then read Hanyu Pinyin, and read this "Mathematics", if I still don't understand these, my Lu Gong's book will inevitably be too unmotivated." ”

Lu Xichun grinned: "I'm not as good as my father, if it wasn't for my father's reminder, I wouldn't have understood." ”

"The reason why I say that Qin Xianao attaches great importance to this mathematics is because he does this, refining the elements of mathematics to form definitions, theorems, and laws, and letting children learn them in the simplest way possible, which is undoubtedly for the future. Lu Gong said in a deep voice, "If the mathematics we need to learn is only this, he doesn't need to go through so much trouble at all, obviously he thinks that this kingdom of mathematics can be drilled down infinitely, and there are countless advanced knowledge waiting for us, but ...... Is this true?"

Lu Gongzhu looked at the bookshelf and looked at the book "Travels to the Immortal Country", and Lu Xichun also looked at it.

"In his "Journey to the Immortal Country", it is recorded that mathematics is one of the foundations of science, and many of the strange and obscene skills in it are said to use mathematics, so mathematics is extremely developed......" Lu Xichun shook his head.

Fuzilou Dong Xiyan put down the "Mathematics" in his hand, and his eyes sparkled.

"Why, why is it the same system, standardization, the same refinement, definition, concept, law, Qin Xian Ao looks so comfortable?"

Dong Xiyan looked at a few booklets on the left, the cover of this booklet was written in four big characters, if someone reads this book, they will find that there are many places in this book that are very similar to the book "Mathematics" released by the Qin Dynasty today.

"I asked my subordinates to write "The Original Book of Arithmetic", which was based on the "Original Geometry", but after reading this "Mathematics", I knew ......"

Organized in the way of "Tool Theory", the result is that Dong Confucianism has made great progress in the innate diagram, Dong Xiyan, Dong Confucianism where does not regard "Tool Theory" as a treasure, although mathematics is difficult to completely "Tool Theory", but Dong Xiyan's subordinates still wrote a "Arithmetic Original" according to the requirements of "Tool Theory" and "Geometric Original", which made mathematics a variety of definitions, concepts, laws and ....... Dong Xiyan was originally very satisfied, but after reading this math.

"There are many more definitions of nouns than in my book, although I don't see any use for these, but Qin Xianao will do useless work......?

"What's especially careful is that this Qin Xianao actually abandoned the number we have been using and used that ...... The number he says in the afterword is from Arabic ......"

Dong Xiyan didn't have to calculate it by himself, so he knew how convenient it would be to use this kind of number that could be written with one stroke in his calculations.

......

Yixue Academy, Cheng Yi scolded the young students below with his hands behind his back.

"Do you think this "Mathematics" is simple? That's right, the old man also thinks it's simple, and he also thinks it's verbose, and it's not even necessary, but if you think about it, these Qin Xianao don't know?"

"Now that Qin Xianao understands, why do you still want to do this? Look at Wang Anshi's change of law, a measurement of the field, will destroy the entire square field tax law, why? It's just that he can't figure out the number geometry. ”

"Why can't you figure it out? You ask yourself, is it easy for Qin Xianao to let you calculate those problems before the algebra in "Mathematics" is written?"

The young people below lowered their heads, the algebraic equations in this book "Mathematics" are easy to solve, but they are easy to solve without algebra, although they can be easily made, but after all, they are not convenient with algebra.

"This is just the enlightenment mathematics that Qin Xianao used to teach naughty children, if it is complicated, what will happen, think about it!"

"Qin Shi Huang unified the written language, and since then, the south and the north can communicate!"

"Qin Shi Huang unified weights and measures, and since then, taxation, commerce have become extremely convenient, and the lives of ordinary people have become better. ”

"Qin Xianao unified phonemes, and since then there has been Hanyu Pinyin Zhuyin!"

"Now that Qin Xianao has once again standardized, systematized, and refined mathematics, what changes will the world of mathematics usher in?"

One by one, the young scholars fell into deep thought.

"Don't think that Mathematics is cheap, you really can't learn it. At this time, at that time, the general trend of the world has changed......"

"The old man is old, so he doesn't have to learn cheap learning, but you, if nothing happens, you will have to live under Qin Xian's arrogance and majesty in the future, will there be such arrogance ?...... then?"

"Qin Xianao has grown into a towering tree, the old man can't protect you for the rest of your life......"

......

After Cheng Yi reprimanded, the corners of his mouth smiled slightly: "Many of you have watched "Nine Chapters of Arithmetic", "Zhou Ji Sutra", and "Sun Tzu Sutra...... If you are waiting for the ten books of arithmetic, of course, you can also take a look at it if you haven't read it, and if you have read it, you should find that the content of Qin Xianao's "Mathematics" is really very simple, and he hasn't written a lot of advanced arithmetic, so this is your chance......"

"Our chance?" many scholars were still confused, and some of the bright, clever eyes had lit up.

Cheng Yi turned around and left the room directly. (To be continued.) )
