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

Pointing to the two people in front of him who were cutting the white paper, Li Yuanjia said casually: "There is no need to delve into the meaning of these two words for the time being...... For now, you just need to know that everything made in our palace workshop must be exactly the same shape, size, and weight, and the same is true for paper! Only if the paper is made exactly the same, it is possible to cut them into finished products of different sizes, but of exactly the same size...... Bong-joo, do you understand what I say? ”

"Well, I see."

After thoroughly understanding the paper production process before, Fang Fengzhu had already understood the meaning of Li Yuanjia's words at this time, and immediately nodded.

Just now, she saw Niu Da "fish" a piece of "wet" paper from the pulp pool, and then saw the "dry" paper plastered all over the walls in the drying room—each of them was exactly the same size. And in this room, Fang Fengzhu saw the whole process of the whole paper being cut.

A piece of paper is divided into two equal parts, and the result is two sheets of paper; Divided into quarters, it is four open sheets; Divided into sixteen equal parts, that is, sixteen open......

Easy to understand and easy to understand at a glance!

After thinking about it for a while, Fang Fengzhu even took the initiative to say: "King, I also understand one thing, it turns out that the paper is cut into two, four, and eight...... Because this is the easiest to cut and the most labor-saving. ”

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

"Hehe, is it just labor-saving?"

Although he was quite satisfied with Fang Fengzhu's understanding, after listening to her words, Li Yuanjia still blinked his eyes and encouraged: "Anything else that I thought of?" Think again! ”

"And ......"

Frowning slightly, Fang Fengzhu subconsciously bit her lower lip.

Seeing that his princess seemed to be racking her brains to think, Li Yuanjia was not in a hurry, and after smiling, he began to look at the data of the paper workshop this month. As for Niu Da, who had demonstrated how to cut a blank piece of paper, he didn't dare to say a word at this time, and stood with his hands down like Wang Pu, waiting quietly.

However, Fang Fengzhu didn't let them wait too long, and quickly shook his head and said, "King, I really can't think of it...... What else? ”

"Haha, don't worry."

Putting down the ledger in his hand, Li Yuanjia laughed and said, "You can think slowly after you go back, don't worry." For now, let's take a look at the carpentry workshop...... Once there, you can really 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 the Han Wangfu, and at the same time to meet the stewards of each workshop - in the words of the king, that is, as the princess, she will take over these workshops sooner or later, so it is still necessary to come and see this morning.

And many things are just by listening and watching, but they are always separated by a veil and vaguely unclear.

So when I heard Li Yuanjia say that I would go to see the carpentry workshop next, I could immediately understand why my own carpenters could do it several times faster than others, and Fang Fengzhu's heart jumped!

This feeling is quite strange.

At least she was sure she had never had one when she was at home before.

Seeing Fang Fengzhu's excited face, Li Yuanjia smiled knowingly. He probably knew her state of mind better than Fang Fengzhu herself, because for anyone who had been locked up in a large courtyard for the first sixteen years of his life and had little contact with the outside world, suddenly touching everything in front of him would instantly have the illusion of finding a purpose in life......

……

Wei Wangfu, study.

"Six hundred and seventy-two divided by fourteen...... Well, equal to forty-eight! ”

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

Just knocking on the table didn't seem to be enough to express the excitement in his heart at this time, and Li Tai pushed the table and stood up suddenly.

Very happy.

As a famous genius of the royal family, although Li Tai's figure is very round, but his brain is very good, not only good at calligraphy and painting, but also has strong attainments in the field of literature, and mathematics is naturally not far behind. In fact, among the six arts of the gentleman, except for the two Li Tai who are not very good at royal and shooting, the other four are all masters!

Calculating a simple division is no problem.

But like the method learned today, you only need to list a strange equation on a piece of paper, and you can get a correct result in a few breaths, but Li Tai has never had an experience! He was sure that if he had calculated it according to the previous method, it would have taken at least ten times as long...... Maybe it's more than that!

"This Tianzhu number is really interesting!"

After walking back and forth in front of the desk for two years, Li Tai sighed with a twinkle in his eyes: "And this so-called division equation is even more wonderful, which can make arithmetic so simple......"

Li Tai, who likes to read, is already quite studious.

Before this, Li Tai really didn't expect that he would turn through a few pages and throw away the math book casually, but he would be out of control when he saw it, and he was completely addicted to it.

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

And......

This is just the second book!

When learning the second book of "Addition, Subtraction, Multiplication and Division", Li Tai was completely confused at first, especially multiplication and division, which made him very annoyed when he was not familiar with Tianzhu numbers, but this also aroused Li Tai's competitive spirit and plunged into the world of mathematics.

It took three days for Li Tai to fully understand this second book.

Of course, the premise is that he already has a fairly strong mathematical foundation, and all that is needed is to be familiar with the use of Tianzhu numbers and the simple rules of addition, subtraction, multiplication and division. For example, the key to multiplication is the ninety-nine multiplication table, in fact, Li Tai has learned it before, and it is not difficult to change the digital version of Tianzhu......

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

There are four more copies!

According to Uncle Eleven, these six math books are written in order of difficulty, step by step, only after learning the front can you go to the back, and one is more difficult than the other, and the things involved are more profound than the other.

So if the rest of the content is gnawed down, it will definitely make people more comfortable, right?

It's just that while he was full of anticipation, Li Tai couldn't help but have a trace of doubt in his heart: "This math is indeed interesting, but relying on these things, can it really increase the production speed of the overturned car by several times as Uncle Eleven said?" In that case, it's amazing......"
