Li Yuanqing laughed dumbly, "Your Majesty is wise."

Liu Pan'er also laughed, this is something Emperor Zhou Ping could think of!

The territory of the Great Zhou Dynasty was getting larger and larger, but the increase in population never happened overnight.

Therefore, relocating the population has become a top priority.

Although there are many convenient facilities at the border or in the south, the people who have relocated to their hometown always feel that they are inferior when they leave their hometown.

As long as I can survive in my hometown and have food to eat, I don't want to go anywhere else.

Emperor Ping of Zhou thought of many ways to relocate the people.

Liang Bao also smiled, "Your Majesty is indeed wise, otherwise he would not be supported by the ministers, nor loved by the people, nor would he be able to realize the Great Zhou Zhongxing."

After Liang Bao talked here and had lunch, he went back to rest.

Li Rong returned to the house with His Majesty, the Queen, and the gifts given to her by the eldest prince.

Li Nan, Li Xiaobao, Li Wei, and even Xie Jindou were also very curious, eagerly waiting for their sister to open it.

"Sister, please open it quickly and let us take a look?" Li Nan urged, a little impatient.

"That's right, sister, you are now a princess. With a distinguished status, you must do things more cleanly and neatly." This is Li Xiaobao.

Li Wei smiled and said, "I want to see what the eldest prince wrote in the letter to his sister?"

Xie Jindou blinked and asked curiously: "Who is the eldest prince?"

Li Nan smiled and said: "It's your future..."

Li Rong quickly covered Li Nan's mouth and said, "Please stop saying a few words to me and I will thank you!"

Li Nan pursed his lips and smiled, "Don't tell me, don't tell me."

Xie Jindou didn't know why. He didn't know at this time that he would become the eldest prince's brother-in-law in the near future.

With such a status, plus being the Marquis of Jinling himself, he will live a lifetime of prosperity and wealth, with no worries about food and clothing.

I read the gifts with my younger siblings, but I have to read the letters by myself.

The eldest prince's letter was also polite, but there was a hint of longing between the sentences.

This is in line with the eldest prince's consistent style.

Self-possessed and steady.

Li Rong thought for a moment, how should she reply to the eldest prince?

No matter how much you say, it may not be specific.

So when Li Rong took some time, she drew some interesting pictures of her brothers and sisters playing in the village.

Funny and lively.

Master Cai finally came to his senses. After eating and drinking, he came to ask Mrs. De Rui, Liu Pan'er, for leave with a question he didn't know.

After Liu Paner learned about it from Liang Bao, he asked someone to prepare the blackboard.

Such a studious person is admirable.

Liu Paner also thought that after teaching Master Cai, Master Cai could teach others in the Imperial Academy.

This Mr. Cai is really extraordinary. He has absolutely no problem with primary school mathematics. He knows everything, and he can also draw inferences from one instance and draw parallels from another.

When I got to junior high school mathematics, I was a little confused about parabolas and geometry.

Liu Pan'er explained it carefully to Master Cai. Master Cai was astonished. Only after he suddenly understood it did he realize the mystery.

"Can it still be like this?" Master Cai exclaimed, blinking in disbelief.

Liu Pan'er smiled and said, "Actually, after careful observation, it is actually like this. Is there anything else Mr. Cai doesn't understand?"

Master Cai studied all afternoon and asked all the questions he didn't know.

With his foundation in arithmetic and his clever brain, he knew how to do it after Liu Paner finished speaking.

Mr. Cai nodded, "There is nothing I don't understand yet. It's just that these mathematical knowledge are really ingenious and can be used in many ways in life."

"Yes, it is widely used." Liu Pan'er replied with a smile, "I have a few more questions here. Do you want to take them back and do them? Not only can you test the results of your learning, but you can also understand where you have fallen short.

, and then you can check for leaks and fill them in a targeted manner.”

Mr. Cai's eyes lit up and he looked forward to it, "I hope Mrs. Derry will give me some advice."

Liu Pan'er put the carefully prepared test paper in the box and pushed it to Master Cai, "It's all in there, Master Cai, take your time."

"Thank you, Mrs. Derui." Mr. Cai, an old man with gray hair, stood up and knelt down to Liu Pan'er to salute.

Liu Pan'er quickly waved her hand and asked someone to help Master Cai up quickly, "Master Cai, please don't do this, I don't deserve your great gift."

Master Cai's attitude was resolute, "Although Madam, you only explained the topics to Cai for one afternoon, you have been my mentor since Cai started learning mathematics, and you deserve a great gift from Cai."

This little old man is very stubborn and bows down very much.

Liu Pan'er couldn't laugh or cry, "It's really not necessary."

Master Cai shook his head and said indifferently, "Madam, your merits are truly admired by the world."

"In the past, arithmetic was obscure and difficult to understand. Only a small number of people had the opportunity to learn it. Many working people and ordinary people had no access to it at all. They could not even learn simple numbers."

"But your mathematics combines arithmetic with some simple numbers and letters from the Western Regions, making some complex arithmetic problems simple and clear at a glance."

"People who are slightly literate or smart can learn by themselves. Even if they cannot learn advanced things, simple addition, subtraction, multiplication and division are enough to be used in daily life."

"Now the people in the Ministry of Industry, one person at a time, are studying intensively. Because they have learned this, they can now have very complete processes and rules for things they usually can only rely on experience to make."

Liu Pan'er didn't think it was a great achievement at first. At first, she only set it up for children to study. Later, she got the Jixiang Library and let the master study and teach the master, and then taught the students in the Jixiang Library.

Because it is easy to learn and easy to use, everyone likes it very much.

She knew the benefits of mathematics, but she didn't expect that the higher-ups in Da Zhou would accept it so quickly.

Liu Pan'er smiled and said, "Thank you Master Cai for the compliment."

Master Cai happily returned to the inn with the questions in hand. He didn't even bother to eat dinner, so he started working on the questions.

I stayed up late into the night, still not satisfied.

After the candles were burned out, everyone else went to sleep. Master Cai went to bed because there was no candle left.

In the afternoon of the next day, I finished it. If I didn't understand something, I flipped through the book and studied it again. Then I gave all the completed questions to Liu Pan'er.

Liu Pan'er's correction is worthy of being a master of arithmetic, he is very good.

Although there is still high school mathematics in the space, Liu Paner has not yet had time to convert it into the current language compilation, and will wait until the capital to give it to Cai Fuzi.

After learning this, Master Cai was very happy, and he used this knowledge to start extension and research.

Master Cai now discovered that some of the obscure and even unprovable things he usually thought about could be answered by applying them.

So Mr. Cai also began to research, which was beyond Liu Pan'er's imagination.

There are many smart people in the world.
