Chapter 1278 Xiangyun’s thoughts (2)

The two of them chatted and laughed and got on the kang. Nangong Yi motioned to Yang Yong to bring the memorial. One of the couple was reviewing the memorial on one side of the kang table, and the other was checking the accounts over there. They were both very attentive, and occasionally they would understand each other tacitly. They raised their heads and looked at each other and smiled, it was so warm!

Near noon, Caiwei finally finished calculating all the accounts. She put down her pen, knocked on her neck and said, "I'm done, how long do you want?"

Nangong Yi raised his head in surprise and said, "So fast?"

"certainly!"

Caiwei proudly raised the account book in her hand and said: "A total of 20,200,000, 1,500, 26,000,000,000,000,000 and 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 and The carriage and horse expenses of thirteen taels are the same as calculated by the Ministry of Internal Affairs.  "

Nangong Yi's sharp eyes suddenly saw the straw paper she used to settle accounts. He saw that it was full of strange symbols and said curiously: "What are you writing? It's so weird. How do you settle accounts with these things?"

Caiwei said: "These are called Arabic numerals, which are specially used for accounting. Accounting with these numbers is much simpler than the accounting methods we commonly use!"

The man nodded in agreement. It only took her so little effort to calculate such a large account, which shows that the effect is indeed extraordinary.

He said: "Is this also passed down from your Fuyou Island?"

Caiwei smiled sadly and said, "Yes!"

The man nodded and said nothing.

Caiwei guessed his thoughts and said: "This method of calculation is very effective. It is simple and accurate. If it is widely promoted among the people, it will definitely be of great benefit to the people."

Nangong Yi said: "This is Fuyou Island's secret knowledge. Can it be passed on to others at will?"

"Of course," Caiwei said without hesitation: "As long as it can benefit the people, Fuyou Island can do anything!" "

After hearing this, Nangong Yi said happily: "In this case, I would like to trouble my wife to pass on this method of arithmetic so that the common people can benefit from it."

The method of Arabic arithmetic can be learned by even third-grade primary school students in Caiwei's world, but in this feudal and backward world, it can be regarded as an extremely advanced academic form, even for people like Nangong Yi. surprise.

Of course Caiwei doesn't mind spreading this kind of knowledge and culture, but she also has some ideas of her own - she wants to pass on this arithmetic skill only to women, so as to improve women's social status! "

She said: "I thought about it and thought that I could open a girls' academy and recruit girls from the official families of the third-rank and above officials in the court to study here. Not only will these rich girls be taught arithmetic, but there are also other things on Fuyou Island. It deserves to be widely promoted. In this way, not only can arithmetic skills be spread, but also women's social status can be improved, and maybe it can also promote the economic development of our country!"

Nangong Yi said: "Although this method is good, I just open an academy and you will have to work hard again. I can't bear it, so I'll let you teach a few people, and then let them go out to teach."

Caiwei smiled and said: "In that case, I will teach my subordinate Liu Xi. He is very smart and will definitely learn quickly!"

Nangong Yi said: "Okay, if you say Liu Xi, just Liu Xi!"

outside the palace

Liu Xi sneezed, not knowing that he had been noticed by the Empress. At this moment, he had just come out of the village in Xiangyun. The young lady experienced the danger last night and looked very bad. Fortunately, there was no serious problem. However, her mother, Mrs. Wu, and her mother-in-law, Mrs. Bai, were talking to her on the left and right, very considerately. Seeing that she was fine, Liu Xi conveyed the Queen's condolences and left. When he left, the steward in Zhuangzi was leading a few craftsmen to repair the windows of the main house, which were said to have been broken by bandits during the attack.
