Princess's House.

Only a month later, Li Chong and Li Lizhen got along very well.

Share a bed.

Even every morning when he was going to be on duty, Li Lizhi would watch him go out.

However, today Li Zhong found an extremely serious problem.

That is, after he crossed over, he originally planned to enjoy himself.

Why has it become a social animal of Datang now, and he has to be on duty on time and on time every day?

"This ...... What the hell went wrong!? ”

And in different scenes, he also has different names given to him by others.

In Guozijian, others call him Master Li.

In the East Palace, others called him the prince and the prince.

In the court, or in the Taishi Bureau, most people call him the captain of the horse.

Of course......

And in the Academy of Sciences, others generally call him Dean.

Unconsciously, he seemed to be called more and more.

But you don't think it's good to say that you don't have these titles.

Because in the Tang Dynasty, the more titles you have, the more you can prove your high status, so that your family will not lose face when they go out.

Arrived at Guozijian.

Someone specially helped Li Chong lead the horse to park.

And Li Chong, who was next to a pillar and watched the doctor of Guozijian give a lecture to the students.

Actually, it's okay.

Anyway, most of the arithmetic problems, now with equations, are not a problem.

The headache should be the arithmetic questioner.

It's not easy to solve the arithmetic problems now, because as soon as the equation comes out, you can hardly see the problem.

really did it, as long as you can count, you don't need it for half a year, you can become a teacher.

And now even the calculations are saved.

This is Wang Xiaotong's decision, because this kind of reform that betrays his ancestors and forgets his ancestors cannot be borne by Li Chonglai.

It can be seen that Dr. Wang is also very far-reaching.

Of course!

Arithmetic is not only about calculating equations, such as finding areas, finding volumes, calculating the distance from the sun to the earth, as well as calculating the height of mountains and valleys.

And rather, these are the most common encounters in real life.

This requires Li to see if he can further improve it.

And then......

Guozijian's students have to learn a lot more alphabets.

For example, the area s, the height h, and some common names should also be changed.

In the past, "Guangcong" was used to represent "length and width", but now it is directly used for length and width.

Moreover, for the statement of area, the various calculations are not very unified, and Li Chong feels that they should be abstracted and unified.

In order to enable students to use it more proficiently, Li Chong also had to combine it with reality and write teaching materials.

In the case of going deep into the grassroots and collecting materials from various sources, he finally compiled an easy-to-understand book of calculations with pictures and texts, and the name is ......

Holding Li Lizhi in her arms, the girl was full of fragrance, and asked, "Anyway, the princess thinks...... What should be the name of this textbook? ”

Don't be ashamed, just use "Li Chongsuanjing" directly.

And Li Chong didn't do this, which proves that Li Chong still has to face.

Li Lizhi looked at so many pictures, compared with other ancient books that are obscure and generally only have words, there is obviously a big difference, and she also said meekly and demurely: "This name should be related to these pictures, right?" ”

Then Li Zhong wrote down casually, "Area and Volume Calculation of Commonly Used Figures".

It's still not that accurate, but it's ......

As long as he adds a schedule to the end, it should be about the same.

At last......

The title of the book became "Area and Volume Calculation and Practical Applications of Common Graphs".

As soon as this book came out.

The officials at the bottom who went to measure the acres of land and count the earthwork were shocked.

Because you made the calculations so simple and easy to understand, how are we going to eat in the future?

The book was completed, and after review, there was no problem.

At last... (This chapter is not finished!) )

Chapter Ninety-Two: Just a Little Curious

…

It is printed.

It is said that Datang has stitching printing, which is really good, but the current application range is still very small.

So when Li Zhong proposed to carry out stitch printing, Li Er also questioned whether it was necessary to do so.

Because when it comes to the importance of books.

There are many books that are much more important than his book.

However, none of those books said that they should be printed.

And, this will increase the expenses of the imperial court.

"Do you think it's necessary?"

Li Er asked Li Chong.

Li Chong felt that this was still necessary.

After a long silence, he said, "Yes! ”

Li Er arranged for someone to seal it for him.

Fortunately, the content of this book is not much in terms of content compared to other books.

Therefore......

Even if it is a thousand copies printed, it is acceptable.

After printing.

It's a matter of distribution.

Guozijian's students, doctors, or something, must have a copy in their hands.

As for the rest......

To be honest, it's really not that good score.

Ultimately......

Li Chong can only take it, and if he is willing to receive it, he will receive it, and he will stop after receiving it.

After all, not everyone needs this kind of book.

Of course!

No matter what kind of book it is, it is still a great book for some people who like to collect books.

For example, Li Tai asked Li for an important copy.

Although he was unaware of the contents of the book, it did not affect his determination to have another book in his library.

In the courtyard of the princess's house.

It was the height of summer.

The courtyard is wooded and lush.

It's to give Li Chong a return gift, but seriously, Li Tai doesn't know what Li Chong likes, except for beautiful women.

But now that Li Chong is his sister's concubine, it is definitely not possible to send a beautiful woman to Li Chong.

Then Li Tai could only pick a few good places given to him by his father, and then give it to Li Chong.

"A small gift, I hope the colt won't be disgusted."

To be honest, Li Chong didn't have high requirements for ink at first, but now, he slowly feels that some ink is used for a kind of enjoyment.

So for Li Tai's gift, he naturally accepted it with a smile on the spot.

smiled and replied: "How can I dislike it, but King Yue is too polite, isn't it just a book, as for giving such a big gift." ”

"Ahem! The main thing is that the king also wants to ask the colt for advice. ”

Li Chong said: "King Yue has not learned those symbols and numbers, so he can't understand them, which is also normal." If there is anything that King Yue doesn't understand, he can ask me directly. I'm sure I know it all. ”

"That's not what the king is referring to."

Li Tai said.

"The king is referring to the thing that the colt told the king before."

Li Zhong just finished speaking: "Which one?" Then, it seemed like it was instantaneous.

"What did you mean by the pony?" Li Tai saw that he seemed to understand, so he continued to ask.

Li Chong also asked him: "Why did King Yue suddenly remember to ask this?" ”

This......

What do you want Li Tai to say?

He can't say that he is a little moved.

But more, in fact, there are still doubts.

Then Li Tai said seriously: "It's just a little curious." ”
