Early Tang Dynasty: Tell Li Er I'm a time traveler at the beginning

Chapter 51 That's a Good Excuse
"Queen, you don't know how surprised the doctors and students of the Imperial College were when the teacher calculated the answer."

"Is it so exaggerated?"

"You don't understand Lizhi. You can't even count."

"The elder brother of the prince can't figure it out, but Lizhi has learned it long ago."

"Then what is 32 divided by 120?"

"Queen, elder brother is a bully!"

Empress Changsun couldn't stand it anymore, and asked, "Do you know how much it is?"

Li Chengqian was very honest, he spread his hands and said, "I don't know either."

"..." Empress Changsun.

"But the teacher knows it, and he can figure it out at a glance, without any calculations at all."

In fact, Li Chengqian was just talking nonsense, even, the above two numbers were all made up by himself.

Li Chong had never calculated 32 divided by 120 at all.

However, this does not affect his admiration for his teacher in the slightest.

His teacher is the smartest in the world!
Horror!
Then he was almost fined by Empress Changsun to do a hundred arithmetic problems.

The ancient gentlemen have always learned arithmetic, and it is also one of the six arts.

If it was too difficult, Empress Changsun would not ask for it.

But at least...

Some simple ones, the prince must know it himself.

Asked the prince if his teacher taught him arithmetic, the prince shook his head, and Empress Changsun asked him to go back and let his teacher teach him arithmetic.

Blame Li Chong, as the prince's teacher, why didn't he teach him arithmetic.

Li Lizhi just smiled, seeing that you are still in a good mood.

……

And since Li Chong held an exchange meeting in the Imperial College.

More and more people came to visit in the future.

Some came to see that Li Zhongzhong didn't want a wife, and some came to ask him to answer questions.

Those who intentionally or unintentionally asked him if he wanted a wife, Li Chong directly refused.

Because this is not what you can afford.

For those who came to ask for answers, Li Chong had no choice but to tell them to prepare their own pens, inks, papers and inkstones.

because……

You should prepare the most basic stationery by yourself.

otherwise……

How much more expenses will be spent in his house for no reason.

Wang Xiaotong now also relies on Li Zhong.

So much so that Sun Simiao was almost ashamed to come in one day when he wanted to come over for a visit.

Now Li Chongna is famous. Some people even say that he can count all the moons in the sky.

As for who made the rumor...

Use the method of elimination first!Certainly not Li Chong himself.

Because Li Chongxian was in pain, he went to promote himself like this.

Now that you have finished counting the moon, the next step is to count the sky?Then the next step is to behead?

"Only by Li Xueshi's own strength, even if he reaches the sixteenth place after pi, even the father and son of Liu Hui and Zu Chong are far behind. However, this calculus is quite similar to the "Zhu Shu" written by Zu Chongzhi and his son. It's wonderful. It's just...Li Xueshi, yours is more illusory, like a rootless weed, while Zu Chongzhi and his son's are more inclined to start with practical problems."

Speaking of which, the name of "Zhushu" seems familiar, where did I hear it?
"The old man also brought the "Zhushu" to me today, and there are some questions in it. I would like to ask Xueshi Li to try to answer it."

Li Chong remembered, isn't this the one in the legend that no one in the Tang Dynasty could understand, even many doctors couldn't understand it, so it was abandoned by the academy in the end?This is a treasure in the Chinese mathematics world.

Some people even speculate whether the level of Chinese mathematics has declined since the Southern and Northern Dynasties, because no one can understand the things written by Zu Chongzhi and his son.

Immediately, Li Chong took the book in the opponent's hand and read it.

He quickly said: "This book is indeed a bit obscure."

The main reason is that the things of the ancients are often the same as doing Chinese reading comprehension. This is definitely a challenge for Li Chong.

He had to find his concubine Ji to come over and study together.

"You put the book here, and if I have time, I'll see if I can answer it."

"Then I will trouble Bachelor Li."

"Speaking of which, the old man has already recommended to His Majesty Li Xueshi to become a doctor in the Imperial College. Did Your Majesty tell Li Xueshi about this?"

After finishing speaking, Wang Xiaotong saluted with embarrassment again: "This old man is being rude, but this old man feels that it would be a pity if Li Xueshi's knowledge cannot be carried forward."

Li Chong said: "Your Majesty hasn't told me yet, maybe he will tell you later. I haven't been in the palace recently. In fact, I don't know much. If I want to become a doctor for a long time, I'm afraid that I will soon teach no one." It can be taught, so...a time is agreed every year, so that interested people can get together to learn, for ten days or eight days, this is fine."

"The old man will thank Li Xueshi on behalf of all the teachers and students of the Imperial Academy."

"Hey, why such a big gift. It's nothing, it's just a little effort."

"The old man also wants to ask His Majesty to ask Li Xueshi to re-annotate all the calculation books."

"cough……"

"Li Xueshi, what's wrong with you?"

"It's nothing."

Oh, why bother.

But the key point is that he can't refuse. If you refuse, he will say that you are not willing to teach others and are stingy.

Now Datang’s official arithmetic books add up, there should be about ten books, of which nine chapters on arithmetic are very important among the ten books, because it introduces arithmetic in a relatively daily and systematic way, and the examples are also very simple. more.Other books are more specific to one aspect, for example: there is "Zhoubi Suanjing" which is dedicated to astronomy, and there is "Sea Island Suanjing" which is dedicated to calculating the depth of islands and valleys.

To be honest, even Li Chong may not be able to understand some problems.

But still that sentence, what can hinder him is only the problem of classical Chinese translation.

He worked hard, and he should be able to solve it, not to say %, but % or % should be fine.

"Speaking of...does Xueshi Li plan to write a calculation book himself?"

"This... I'm not quite qualified yet."

"From the old man's point of view, Li Xueshi has such qualifications. Moreover, the old man also wants to see Li Xueshi's works as soon as possible."

Li Chong thought for a while, then said: "I'm free, no, I'll try my best."

Originally, Li Chong wanted to refuse, but soon, he changed his mind, isn't this a good way to hide at home and catch fish? Damn, he is really a genius.

If others asked why he didn't go on duty, he would say that he wanted to write the official calculation book of Datang.

If someone asks him to write the calculation book, he should be on the bed?

Then he replied to the other party that he wanted to find inspiration through this.

Ah!
That's a good excuse!
