"It's actually very simple, that's the standard!"

Pointing to the two people who were cutting white paper in front of him, Li Yuanjia said casually: "There is no need to delve into the meaning of these two words for the time being... For now, you only need to know the shape, size and weight of everything made by our Wangfu workshop.

Everything must be exactly the same, and of course the paper is the same! Only when the paper produced is exactly the same, can they be cut into different sizes but with the same specifications... Fengzhu, do you understand what I say?"

"I see."

After having thoroughly understood the paper production process, Fang Fengzhu now understood the meaning of Li Yuanjia's words and nodded immediately.

Just now, she saw with her own eyes that Niu Da "fished" out a piece of "wet" paper from the pulp pool, and then saw with her own eyes the "dry" papers that were covered with walls in the drying room. Each of them was

Exactly the same size. And in this room, Fang Fengzhu saw the entire process of cutting the entire piece of paper.

Divide a piece of paper into two equal parts, and you get two pages of paper; divide it into four equal parts, and you get four pages of paper; and divide it into sixteen equal parts, and you get sixteen pages of paper...

Simple and easy to understand, clear at a glance!

After thinking about it for a while, Fang Fengzhu even took the initiative to say: "Your Majesty, I also understand one thing. It turns out that the paper should be cut into two pages, four pages, eight pages... because this is the easiest way to cut and saves the most labor."

It is easiest to divide a piece of paper into two equal parts. To divide it into four equal parts, you only need to divide the two pieces of paper into equal parts again.

"Haha, is it just to save labor?"

Although he was quite satisfied with Fang Fengzhu's understanding, after listening to her words, Li Yuanjia blinked and encouraged: "Have you thought of anything else? Think again!"

"besides……"

Frowning slightly, Fang Fengzhu bit her lower lip subconsciously.

Seeing that his princess seemed to be racking her brains, Li Yuanjia was not in a hurry. He smiled and started to look through the data of the papermaking workshop this month. As for Niu Da, who had finished demonstrating how to cut a piece of white paper,

At this moment, he didn't even dare to say a word, just like Wang Pu and others, they stood with their hands down, waiting quietly.

However, Fang Fengzhu didn't keep them waiting for too long. He quickly shook his head and said, "Your Majesty, I really can't think of...what else?"

"Haha, don't worry."

Putting down the account book in his hand, Li Yuanjia laughed and said: "You can think about it slowly after you go back, don't be in a hurry. For now, let's go to the carpentry workshop first... Only when you get there can you truly understand the role of standards!"

"……good!"

Biting her lip, Fang Fengzhu nodded happily.

Today she followed Li Yuanjia to the farm outside the city, just to see all the workshops in Prince Han's palace, and at the same time meet the stewards of each workshop. In the king's words, as the princess, she will take over these workshops sooner or later, so

It is still necessary to come and take a look this morning.

And there are many things that just rely on listening and seeing, but there is always a layer of veil between them, and you can't see clearly clearly.

So when Li Yuanjia said that he would go to the carpentry workshop next time, Fang Fengzhu's heart became excited when he thought that he would immediately understand why his own carpenters could do work several times faster than others!

This feeling is quite strange.

At least she was sure that she had never had it at home before.

Seeing Fang Fengzhu's excited face, Li Yuanjia smiled knowingly. He probably understood her mentality at this time better than Fang Fengzhu himself, because for anyone who had been locked up in prison for the first sixteen years of his life,

In a big courtyard, for people who rarely have contact with the outside world, if they are suddenly exposed to everything in front of them, they will instantly have the illusion that they have found the goal of life...

…

Wei Wangfu, study room.

"Six hundred and seventy-two divided by fourteen...well, equals forty-eight!"

After calculating the answer on the paper, Li Tai's little eyes suddenly opened, he couldn't wait to look at the answers at the back of the book, and then he immediately knocked on the table happily: "Haha, right again!"

Just knocking on the table seemed not enough to express the excitement in his heart. Li Tai pushed the table and stood up suddenly.

Very happy.

As a well-known talent in the royal family, although Li Tai has a round figure, his brain is very good. He is not only good at calligraphy and painting, but also has strong attainments in the field of literature, and his math skills are not much different. In fact

, among the six arts of the gentleman, except for Yu and archery, which Li Tai is not very good at, the other four are all masters!

Calculating a simple division is certainly no problem.

But like the method I learned today, you only need to list a weird calculation formula on a piece of paper, and you can get a correct result in a few seconds. But this is an experience that Li Tai has never had before! He can be sure that if he still follows the

If calculated using the previous method, it would take at least ten times more time... maybe even more!

"This Tianzhu number is really interesting!"

After walking back and forth in front of the desk for two times, Li Tai sighed with bright eyes: "And this so-called division formula is even more magical, it can make arithmetic so simple..."

Li Tai, who likes reading, is quite studious.

Before this, Li Tai really didn't expect that the math book he thought he would flip aside after flipping through a few pages would actually get out of control and become completely addicted to it.

After finishing the so-called "exercises" in this book today, Li Tai felt a long-lost sense of satisfaction!

and……

This is only the second book!

When learning the second book "Addition, Subtraction, Multiplication and Division", Li Tai was completely confused at first, especially multiplication and division, which troubled him very much as he was not familiar with Tianzhu numbers, but this also happened to arouse

He caught Li Tai's competitive spirit and plunged headlong into the world of mathematics.

It took Li Tai three days to thoroughly read this second book.

Of course, the premise is that he already has a strong foundation in mathematics. All he needs is to be familiar with the usage of Tianzhu numbers and the simple rules of addition, subtraction, multiplication and division. For example, the key to multiplication is the multiplication table, which Li Tai has learned before.

, it’s not difficult to change to the Tianzhu digital version...

Looking at his desk, Li Tai's eyes shone with excitement.

Four more to go!

According to Uncle Eleven, these six mathematics books are written in order of difficulty, step by step. Only after learning the previous ones can you read the later ones. Moreover, each one is more difficult than the last, and the things involved are more complicated than the last one.

of profundity.

So if you chew on the following content, it will definitely make people feel more comfortable, right?

But while he was full of expectations, Li Tai couldn't help but feel a little doubt in his heart: "This mathematics is indeed interesting, but relying on these things, it can really make people overturn as Uncle Eleven said.
Chapter completed!
