Chu Yan, this name is not prominent in the history of mathematics, because this guy's real specialty is astronomy. The new calendar of the Great Song Dynasty Chongtian Calendar was made up by this guy and nine people including Song Xinggu, the official in charge of the calendar.

Few people know that in addition to being proficient in astronomy, this guy is also proficient in tuibu, luni-yin, and ephemeris.

Arithmetic is just one of many majors in this guy.

Although he is not famous, he has an apprentice who is famous in the field of arithmetic.

His apprentice's name is Jia Xian, Jia Xian is the author of "The Yellow Emperor's Nine Chapters of the Calculation of the Scriptures", the original book was lost, but the main content of it was copied by Yang Hui's book "Detailed Explanation of the Nine Chapters of Algorithm".

In Yang Hui's "Detailed Explanation of the Nine Chapters of Algorithm", there is a record of the 'origin of open practices', which is known to later generations as the 'Yang Hui Triangle', and Yang Hui clearly marked 'Jia Xian used this technique' in the book.

When he was a child in school, Yang Yansi thought that Yang Hui was a modern person, and he only knew that the 'Yang Hui Triangle' was made by a person named Yang Hui.

It wasn't until later, when studying history, that I learned that Yang Hui was a mathematician in the Southern Song Dynasty.

And the 'Yang Hui Triangle' also has another name, called the 'Jia Xian Triangle'.

It was also after knowing that Jia Xian existed that Yang Yansi knew that Yang Hui was not the founder of discovering this law, he was just an inheritor.

Europeans call this table of regularities Pascal's triangle. It is said that a mathematician named Pascal in Europe discovered it in 1654.

However, compared with Jia Xian and Yang Hui, it seems to be hundreds of years later.

Perhaps, this thing is a European who traveled across the ocean in China to get the book "The Yellow Emperor's Nine Chapters of the Sutra and the Fine Grass", and then quietly took it back to Europe......

Many questions are not dared to be delved into and imagined.

The more I think about it, the more I might ...... The closer you get to the truth.

At this moment, Yang Yansi looked at the unfinished 'Yang Hui Triangle' in front of him, and his heart was full of infinite emotion.

After doing it for a long time, this thing was actually discovered by Chu Yan first.

If I had perfected this law and recorded it in a book, would it be called the 'Yang Yansi Triangle' when future generations read the book?

Thinking of this, Yang Yansi picked up the pen and began to solve the problem, and it only took a quarter of an hour to complete all three questions.

'Yang Hui Triangle' is destined to change its name.

……

"This ......" Chu Yan stared at the perfect triangle law diagram in his hand and asked Yang Yansi, "How did you do it?" ”

Yang Yansi smiled stinkily, held the shelf, and said, "Maybe, I'm a genius." ”

Chu Yan took Yang Yansi's answer sheet, pulled up a few doctors of Taixue arithmetic who were watching the battle, and started to do research together.

Wang Qin was a little dumbfounded, "That's it...... Cleared? ”

Yang Yansi walked in front of Shen Lun and bowed down, "Shen Xiangye, this is another victory in the late life." Don't know what's next? ”

Shen Lun's face was a little unpleasant.

Although he didn't like Wang Qin's approach, he agreed with Wang Qin's idea.

It's not good for young people to be too vigorous, so they are going to suppress Yang Yansi for a while, and then they will be included in the introduction and taught well.

For this reason, he did not hesitate to dig deep and invited Chu Yan, an unknown arithmetic master.

I didn't expect that the hidden arithmetic masters would lose so quickly and so completely.

Even, from this kid's hand, I got guidance.

Because of this kid, now Taixue has paralyzed two departments.

The chess doctors were too lazy to teach the students now, and they all gathered around Liu Xin to study the zombie flow and the big avalanche pattern with him.

The doctors of painting art were obsessed with Yang Yansi's sketching skills, and they didn't know how to get Yang Yansi's paintings, so they began to copy them behind closed doors all day.

Now it seems that the doctors of arithmetic are not immune to the poison.

Shen Lun was considering whether to continue the assessment.

What if this kid really clears all nine assessments perfectly?

When the time came, he didn't suppress this kid, but he was paralyzed by this kid.

"Your Majesty's birthday is imminent, and Taixue still has to help the Ministry of Rites to manage the banquet together, so I don't have time to assess you for the time being. What is the next test and when is the assessment time, the old man will send someone to inform you separately. Shen Lun said with a straight face.

"Your Majesty's birthday?" Yang Yansi's eyes rolled, he thought of something, and hurriedly saluted Shen Lun, "In that case, the kid will retire first......

Taixue in the hall.

A group of Taixue doctors shook their heads around Yang Yansi's test paper.

Shen Lun scolded with a dark face, "Something that doesn't make a difference." ”

Not only did the doctors of Taixue not get angry, but they saluted Shen Lun and said, "I think that Yang Yansi is far above us in terms of arithmetic ability. I implore Shen Xianggong to allow Yang Yansi to enter Taixue and take charge of arithmetic. ”

Wang Qin jumped to his feet when he heard this.

"A monkey whose fur hasn't grown yet. It's not even a student, so what qualifications do you have to learn arithmetic? ”

The doctors of Taixue arithmetic are not afraid of Wang Qin and say bluntly, "In terms of learning, those who reach the level are the first, and we are willing to humbly seek advice." Moreover, we are in charge of arithmetic, and we will have the final say on who is in charge of arithmetic. ”

"You!"

Within Taixue, doctors of arithmetic are a special group of beings. They are often transferred by various ministries of the imperial court to help, and the imperial court checks taxes every year, and they are the main force.

There is no substitute for them.

Zhao Guangyi is very important to these weapons!

Wang Qin didn't dare to offend them at will.

Shen Lun frowned and asked Chu Yan, "Chu Yan, what do you think Yang Yansi has achieved in arithmetic?" ”

Chu Yan thought for a while and was puzzled, "Among the known arithmetic masters, he is unmatched. ”

Chu Yan was very conservative in what he said, he couldn't be sure if there were other arithmetic masters in the mountains and wilderness that he didn't know.

"The old man will think about this matter carefully, you go down first!"

The doctors of Taixue arithmetic left, but they did not give up, and after returning to the house, they began to write a memo, imploring Zhao Guangyi to approve Yang Yansi to take charge of Taixue arithmetic.

This news reached the ears of the doctors of painting and chess, and they also began to act.

Doctors of painting and chess do not have the stubbornness of arithmetic scholars. Their request to Zhao Guangyi was to ask Yang Yansi to be a doctor of painting and chess.

This country's supreme holy place of learning and literature was boiling all of a sudden because of Yang Yansi.

Yang Yansi, the initiator, didn't know this, so he went out of the side hall, picked up She Saihua and Yang Yanqi, and the group got into a carriage and returned to Tianbo Yang Mansion.

As soon as she entered the mansion, Yang Yansi shirked She Saihua's banquet to celebrate her and went into the kitchen alone.

No matter how others persuade him, he just stays inside and doesn't come out......
