After visiting the Bashui Villa with Jin Shengman, Li Yuanai began to carefully compile the "Suan Jing".

Li Zhi gave Li Yuanai great convenience and directly appointed Li Yuanai as the Grand Secretary of Hongwenguan and the Bachelor of Hongwenguan, and the students were arbitrarily assigned.

Then, at the request of Li Chunfeng and Yan Liben, he assisted Li Yuanai in compiling the "Absolution of the Sutra".

Rather than saying that they assist from the side, it is better to say that they are listening to the class and studying.

The development of Chinese numerology is still extremely advanced. After Liu Hui's notes, "Nine Chapters of Arithmetic" has been very accurate and includes the comprehensive enlightenment of numerology. Its appearance marks the formation of a complete system of ancient Chinese mathematics.

Therefore, Li Yuanai wrote "Authorization" as a high-level course, not for children to enlighten, but also for high school or above knowledge. What kind of dimensional equations, trigonometric functions, etc.

Before teaching these, Li Yuanai began to promote the Tang Dynasty numbers to the outside world.

The so-called Tang Dynasty numbers are Arabic numerals. If you want to learn and develop in profound mathematics, Arabic numerals are indispensable.

The expression of Chinese numbers is too complicated.

Mathematics is a very complex science that requires various complicated calculations.

If you use Chinese, it will test your IQ.

Just like the circumcision technique in the introduction to arithmetic "Nine Chapters":

Cut six goblets and think they are twelve goblets.

The technique says: Put the circle diameter two feet, and half is one foot, which is the face of the goblet inside the circle. Let the radius one foot be the string, and half face five inches are the sentence, and find the strand for it. Use the 25 inches of the sentence power to reduce the string power, and the remaining 75 inches are the remaining, and then it will be divided into seconds. Another method of retreat is to find the minus number. The minus number is unknown and uses ten as the denominator, which is about 5 minutes and 2 minutes and 2 seconds and 5 minutes and 2 seconds. To reduce the radius, the remaining 1 inch, 3 minutes and 3 minutes and 9 milli seven seconds and 4 minutes and 5 minutes and 3 minutes and 3 minutes and 7 seconds and 4 minutes and 5 minutes and 3 minutes and 3 minutes and 7 minutes and 4 minutes and 5 minutes and 3 minutes and 6 minutes and 7 minutes and 4 minutes and 5 minutes and 7 minutes and 5 minutes and 7 minutes and 5 minutes and 6 minutes and 7 minutes and 6 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and 7 minutes and

If you open the square and remove it, it is the surface of one of the twelve goblets.

...

Using Arabic numerals to calculate formulas can be made clear at a glance, while using Chinese calculations, you have to write more than a hundred words to describe them, and this is just the simplest thing.

What is really difficult is that you have to write one or two thousand words to verify the calculation in one solution, and your mind will be dizzy.

There is no reason why Arabic numerals are used all over the world.

It provides complicated numerical calculations and provides the greatest and optimal convenience.

If you want to truly improve the qualitative change of Chinese numerology, you must first simplify the numerology, integrate into society and life.

1,2,3,4,5,6,7,8,9,0 is not difficult? But 1,2,3,si,5,lu,7,8,9,0 is not easy.

Therefore, when I started to write the "Absurd Sutra"? In the first step, Li Yuanai became a teacher? He introduced Arabic numerals to Li Chunfeng, Yan Liben and a number of bachelors from Hongwenguan.

Arabic numerals were not actually invented by Arabic? The earliest numbers originated in the third century AD. Baghdad, a scientist in ancient India, invented Arabic numerals? But the number was only invented to 3. If you want to get 4, you need to use 2 plus 2 to represent it.

It seems stupid now? But I don’t know that just a 4? It has been used for hundreds of years in the history of mathematics.

Finally, the ancient breeze improved on this basis and invented the expression of numbers 1 to 0, which became the basis for counting.

About 700 AD, Arabia began to march eastward. They were surprised to find that the mathematics of the conquered areas was more advanced than them, so they tried to absorb these numbers.

The Arabs passed this number to Spain and then from the Pope to Europe, which was called Arabic numerals.

But in fact, the origin of Arabic numerals was in ancient India.

However, even in ancient India, their true writing may not be the current Arabic numerals? It's just that it's relatively close. Today's 1 to 10 were improved by many mathematicians in later generations who spent a lot of effort to improve it bit by bit.

Therefore, the so-called Arabic numerals have nothing to do with Arabic? Li Yuanai is unceremonious here and is crowned with the Tang Dynasty numbers.

If it weren't for a little bit of face, Li Yuanai would like to name him the Shang King number? Or the Li Yuanai number.

In this way, the title of the number one mathematician in history is truly impressive.

The numbers in the Tang Dynasty are simple and easy to understand, which is something that young children can accept?                                                    �

Simple symbols? The concise and concise expression instantly made Li Chunfeng, Yan Liben and others realize that this extremely simple number will be a major change in the history of numerology.

However, one person below said: "This kind of record is indeed simple and convenient, how can it be written in a book?"

Li Yuanai was stunned at first, and then he realized that the writing at this time was written vertically.

The main reason is probably that the writing materials of the early Chinese characters were wooden slips, bamboo slips, writing tools were brushes, Chinese characters were square characters, etc. Although paper was invented after the Han Dynasty, the way of writing Chinese characters had a long history. Moreover, the writing of Chinese characters from top to bottom, from right to left, also reflected the ancients' high and low thoughts.

"This question is well raised!" Li Yuanai smiled and said, "I have indeed ignored this point. The top-down record is indeed inconvenient to the reading and comprehension of numerology. Let's go back and ask the prince, Your Majesty for instructions. My numerology books can be written horizontally, from right to left for understanding."

If you propose horizontal writing from left to right, you will most likely encounter great difficulties. However, horizontal writing from right to left is not a problem for others except that he is not used to it.

Because plaques and other things are written horizontally from right to left in many places, modifications in this regard can be accepted by the public.

The man nodded without saying a word.

Seeing that you had a handsome face and a heroic spirit, Li Yuanai asked more, "Who are you?"

The other party knelt on the table, and heard this, and stood up and bowed: "My younger generation Pei Xingjian, a student of Hongwenguan, have met the King of Shang."

A strange look flashed in Li Yuanai's eyes. He was really a celebrity and famous man running all over the streets: the most famous Confucian general of the Tang Dynasty was Li Jing, a student of Su Dingfang. He was a civil and military position, traversing the Western Regions and threatening the Turks. He not only knew how to use troops, but also knew people. He promoted many people, who were famous generals in the Tang Dynasty, who fought against the surrounding alien races, but unfortunately most of them were cut by Wu Zetian.

Such a person actually works as a student in Hongwenguan?

Li Yuanai nodded to it, and then said to everyone: "I plan to create a change for our dynasty. This change will inevitably be omitted. I hope you can help me with your help, just like Pei Xingjian, when you encounter questions, so that you can make up for the omissions."

Li Yuanai bowed to everyone in the hall.

Everyone hurriedly returned the gift, and everyone was happy.

All of them will be honored to be able to complete this change and will be recorded in history.

As Li Yuanai imagined, it was not a big problem to pass his proposal to Li Zhi.

Li Zhi is on his side, opening the door to convenience.

The civil and military officials had no objection. The issuance of Tang Dynasty numbers was convenient for the people of the Tang Dynasty and was beneficial to life.

Only when the vertical is written to horizontal is changed, some old scholars put forward different meanings.

But it was useless, and Li Zhi was getting closer and closer to Changsun Wuji.

Before, Li Zhi felt that the "Zhenguan Law" was a bit outdated. The Tang Dynasty had been developing for twenty years, and many of the policies in the "Zhenguan Law" were not suitable for this era.

He intends to make small-scale revisions on the Zhenguan Law.

This move was recognized by Li Shimin, and Li Zhi directly appointed Changsun Wuji to be responsible for the matter, and the relationship between the two parties also went further.

As long as Changsun Wuji does not sing the opposite tune, Li Zhi, the prince of the governor, will have enough voice.

The people of the world all supported the implementation of the Tang Dynasty numbers.

The numbers in the Tang Dynasty are so simple. This is something that young children can learn, which is easy for adults to accept.

Especially businessmen, they prefer this simple counting method, which has also made great contributions to the promotion of Tang Dynasty numbers.

With the Tang Dynasty numbers, symbols such as addition, subtraction, multiplication and division are simple to implement.

Li Chunfeng smiled bitterly in class and said, "Was the King of Shang invited us to edit books together or class? Why not do this? Your Highness might as well compile a simple number first, and then compile the Tianyuan technique and the method of increasing and multiplication in the future. This Tang Dynasty number is too convenient to combine with addition, subtraction, multiplication and division. As long as the number is worth promoting, most of my Tang Dynasty documents, masters and staff must retire."

In ancient times, documents, teachers and staff were very popular because they were difficult to understand.

The introductory numerology "Nine Chapters of Arithmetic" looks like a book of heaven without a certain degree of numerology.

But the Tang Dynasty numbers simplified all this. Once the learning of numerology is not difficult to reach the sky.

Li Yuanai smiled and said, "This is a good suggestion, so I will compile a book about math and practice my skills first."

As for the questions raised by Li Chunfeng, it is not his consideration.

The times keep pace with the times, and society is also progressing.

If primary school students cannot accept addition, subtraction, multiplication and division, they will be eliminated.

No one can blame!

Li Yuanai, Li Chunfeng, Yan Liben and his group spent three months to compile a book called "Enlightenment Sutra", which was filled with calculation formulas of addition, subtraction, multiplication and division, and wrote all the mathematics of the third grade of elementary school in it.

Although math in the third grade of elementary school, the most practical one is mathematics within the third grade of elementary school.

Addition, subtraction, multiplication and division of these numbers are used in life, but are practical for a lifetime.

Parents with children can understand the best. Mathematics within the third grade can be bragging about their children and ask me if they don’t understand. But when they are in the fourth grade, then save money.

After passing this hurdle, most people who are not involved in this industry have forgotten everything.

If your child asks you these questions, he will not be able to answer them if he doesn’t read the book and review the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn the past and learn

Therefore, the "Enlightenment Sutra" is enough to benefit people of this era.

After all, it is a feudal society, and it is impossible to expect everyone to have a diploma above high school.

As soon as this book of "Enlightenment Sutra" was promulgated, it was immediately sought after by merchants and the people.

The contents are too simple and practical.

Originally, big merchants deceived small merchants, while small merchants deceived the people.

The addition and subtraction of more than a hundred digits is ignorant, and the people are just like listening to the heavenly books.

Most of the transactions of food, money and silk are about what others say. Now, as long as you calculate it, it is very clear and no one can deceive anyone.

The practicality of mathematics has been widely circulated among the people and merchants.

As for the Shilin side, their attitude was not significant, they were a little ambiguous, and they did not admire it, and they looked like they were free.

What Li Yuanai didn't know was that everyone in the aristocratic family representing the core of Shilin was already a little panicked.
