Why is this happening!

Why is this happening!

Wang Ou's three views were a little broken.

She started reading since she became sensible. The Wang family in Taiyuan has been passed down for thousands of years and has a deep family education. She even collected more books than the imperial palace. Wang Ou is also a person who likes to read. The books she has read are no less than any great scholar.

The teachers who taught her were all famous officials in the world. From them, Wang Ou concluded that it is not difficult to learn a science, but it is difficult to become a master of a science. Therefore, it is common for erudites, but there are rare masters who are proficient in a subject.

But Li Mu's appearance made her shaken.

He is only seventeen years old.

Wang Ou has seen many young men at the age of seventeen. Among the aristocratic families, there is no one in the world who fought in the world at the age of seventeen. At the age of seventeen, he was the age of riding a horse and being idle. The Analects of Confucius says that he was established at the age of thirty. A saint is not just a saying. At the age of thirty, it would be extremely difficult to have his own academic system and his prestige.

But the seventeen-year-old Li Mu not only has unparalleled poetry and prose, but also invented Zhenguan plow, horseshoe, printing, and new winemaking methods... which one is enough to be praised. Now he has demonstrated his ability in mathematics. Is there really a genius in this world?

Mingjuan has always been a profound science in ancient times and is also one of the examination subjects for the regular examination subjects of the imperial examination. There are regulations in "Tongdian·Election" to "Mingjuan" and "Nine Chapters of Laws", "Zhang Qiujian", "Xiahou Yang", "Zhou Feng", and "Five Classics" and "Six Perfections" respectively. Those who have ten or six passes are passing; those who have ten or three passes are passing through the book reading, and those who have ten or three passes are passing through.

Simply put, if you take the math exam, you can get a high school student after taking the 60s. You can get a high school degree after the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank of the rank

It seems very simple, but during the imperial examination, there are the fewest people who can make the first pass, because mathematics does not look like the meaning of the classics, and can have a concrete understanding. For example, in terms of filial piety, everyone knows what filial piety is. Even if they are not filial and have no loyalty, they know what filial piety and loyal people look like. However, mathematics requires logic and even imagination, which was very difficult for the ancients.

In ancient mathematics, in addition to the concept of addition and subtraction that naturally formed. The concept of multiplication and division was formed relatively late. The concept of multiplication and division was well documented. The concept of Chinese multiplication first appeared in the Spring and Autumn Period and the Warring States Period. In books such as Xunzi, Guanzi, Huainanzi, and Warring States Policy, you can find sentences such as "3927", "6848", "4832", and "6636". During the Han Dynasty, these sentences were combined to form the original "Nine Cause Song", which is the current "Nine Cause Song", which is the current "Nine-Nine Multiplication Table".

The concept of "exclusion" was not proposed in general until the Wei Dynasty of the Three Kingdoms and Wei Dynasty, when Liu Hui explained "Nine Chapters of Arithmetic".

In later primary schools, four calculations were learned in elementary schools. The ancients only summarized them for thousands of years from the Spring and Autumn Period to the Three Kingdoms. Even so, the largest number used in ancient times was only 'ten thousand', usually between thousands and hundreds of times. Even such a small number was very troublesome to calculate. Therefore, only those who know how to calculate can become officials.

But today, after Wang Ou read Li Mu's four-character algorithm, he suddenly felt that in his heart. In the future, a certain degree of calculation may change. Although Li Mu's four-character algorithm does not transcend the framework of "Nine Chapters of Arithmetic", the method he used is more than ten times simpler. "Nine Chapters of Arithmetic" is a book that only people with certain accomplishments in mathematics can understand. When Li Mu found these symbols, even if someone illiterate craftsmen explained it to him, he could understand them.

If the four calculations are promoted, and the original test questions are taken in the Ming calculation subject, there will probably be hundreds or thousands of people who can pass the exam.

The four algorithms made Wang Ou amazed, and it was already incredible to solve the "Hundred Chicken Question". The Bai Ji Question came from "Qiu Jian Summary", and its nature was somewhat similar to the modern "Godbach Conjecture". Zhang Qiujian, a calculationist in the Northern Wei Dynasty, thought of this question, but he spent his entire life without giving a solution, so he attached it to the end of the book so that future generations can answer it.

However, later generations were not successful. Zhen Luan, a mathematician of the Northern Zhou Dynasty, and Li Chunfeng, who is now known as a "child prodigy", both annotated the "Qiu Jian Summary", but neither gave the answer. Especially Li Chunfeng, although he was only twenty-eight years old this year, his achievements in the field of mathematical science have surpassed those of the ancients. When he was twenty-six, he recompiled and annotated the ten famous mathematicians, which were used as textbook templates for the Imperial College of Corrections. It can be said that the people who study mathematical science now come from his disciples.

Li Mu blurted out the question that he hadn't even solved?

How did he do it!

A sudden agitation of grievances arose in Wang Ou's heart. She was grievances for herself, for Zhang Qiujian, Zhen Luan, and Li Chunfeng. Why is it so easy to get to Li Mu if you have nothing to do with your whole life! God is so unfair!

But she still wanted to know how Li Mu calculated it. Wang Ou took a deep breath, threw away the branches in her hand, looked at Li Mu with a beacon, and said, "Marty, this 'Hundred Chicken Question' is an unsolvable problem in the "Qiu Jian Achievement Sutra" written by Zhang Qiujian, a master of mathematics in the Northern Wei Dynasty. No one can solve it for hundreds of years. The Martyr actually blurted out and gave three answers. The Martyr's profound math is amazing. I really want to know how the Martyr calculated it, so I would like to give you advice."

"ah?"

Li Mu was a little confused. Is the three-way indefinite equation system unsolvable in the Tang Dynasty? If you say that, any college student who travels to the Tang Dynasty can become a master of math. But it may not be necessary. Most college students squat in the dormitory to play games after going to college. He may not be able to solve it if he gives him a three-way indefinite equation system.

In fact, Li Mu also forgot how to solve the system of ternary indefinite equations, but he is a programmer with C instinct in his mind. Although he does not have a computer in hand, such a simple question can still be calculated.

Wang Ou suddenly asked him how to solve it, but it stumped him. He didn't know how to explain C language to Wang Ou, and he had to think about it carefully and sort it out before he could tell what to say.

There is no way, I can only refuse for the time being.

Li Mu thought, cleared his throat and said, "Is this solution...the profound part of the algorithm I invented, just like the secret method of a craftsman, do you... understand?"

"Ah?" Wang Ou was stunned for a moment and immediately reacted. Yes, how could such a profound algorithm be taught at will? Wang Ou blushed at her thoughts, and at the same time she was a little resentful. If Li Mu hadn't rejected her, she wouldn't have blurted out so without thinking.

"I am rude, I shouldn't ask."

Li Mu waved his hand and said, "It's not a big deal. I don't have any family opinion. I won't teach you just because you were from the Wang family in Taiyuan. It's just that the algorithm for calculating this problem is very difficult and I can't explain it for a while. I'll tell you in detail when I have free time another day."

Wang Ou quickly said, "I thanked the marquis first."

Li Mu thought for a while and asked, "You just said, "This hundred chicken question hasn't been solved for hundreds of years?"

Wang Ou nodded and said, "The algorithm invented by the Marquis is far beyond the ancients."

"Hey, I can't say that." Li Mu pretended to be modest, but he was a little proud in his heart, saying, "Since that's the case, I should make these four algorithms public so that people in the world no longer have to worry about arithmetic... Baiji Question can just prove my algorithm. OK, I decided to publish the answers to Baiji Question and the four algorithms in the Tang Dynasty Daily tomorrow!" Li Mu couldn't help laughing: "After tomorrow, will this Hou be the master of the Tang Dynasty's mathematics? Hahaha..."

Wang Ou looked at Li Mu's proud look and felt helpless and depressed. She really wanted to see him get defeated, but why did he always surprise him? Suddenly she remembered the new gouache that Li Mu had said that day, and thought to himself, "Can he really do it!"

It took a lot of time to talk about math. Seeing the sun was heading west, Wang Ou said he would not visit today. Li Mu was also thinking about going home early, so he took Wang Ou back to the gate on the same road, and each boarded the bus and got home.

When Li Mu returned home, he had not yet been excited, so he found paper and pen to write down the basic method of the four calculations. He also wrote down the "Hundred Chicken Questions", but did not give the solution, but directly attached the three answers to the back.

After writing, he ran to the printing room. Li Zhien was presided over tomorrow's Datang Daily layout. When he saw Li Mu coming, he put down the manuscript in his hand, jumped into his arms excitedly, holding his neck and playing on the swing.

Li Mu pulled her off and said, "It's so rude in public... Stop making trouble, there's something serious." Li Mu called the craftsman in charge of engraving movable type and said, "Old Bi, look at these symbols and carve them out. It will be published with the Tang Daily tomorrow."

Lao Bi took Li Mu's manuscript in his hand and read it, "Don't worry, these symbols are simple to use and can be carved out in less than an hour."

"Very good. Lao Bi, do your best. Your Majesty gave me the power to appoint officials under the sixth rank of the Ministry of Works. I have sent you an official document to the Ministry of Personnel to find you a seventh rank of printing supervisor. In a few days, all the craftsmen's workshops were packed up, and you will bring the people from our printing houses to move over. From now on, you will become an official in the Ministry of Works. You must study more when printing."

When Lao Bi heard this, he was stunned. After a long time of reaction, he knelt in front of Li Mu and said, "Mr. Marquis, the young master has been craftsmen for generations, how could he be an official? Marquis is so kind, and the young master is grateful, but the young master is worried that he will not do it well, and he will lose his face!"

Li Mu was so stern and said, "The official documents have been sent, but I can't collect them. Your Majesty attaches great importance to the Printing Supervisor. If you don't do it well, it's not my face, but your own life. I don't want to hear such words, hurry up and work!"
