Jinxiu Nanzhi, determined to be the richest woman

At night, Yu Muyun called several sisters to the room and dragged the boxes containing money over.

There are no banknotes here, so every trip is very inconvenient. It would be much more convenient if we had banknotes!

Yu Muyun thought silently in his heart, and opened a few boxes. The girls were stunned when they saw the money inside. It was written as a number, and there was basically no idea of ​​how much it was.

"Take them all out!" Yu Muyun motioned to a few people. There were 20,000 large silver ingots inside, each weighing fifty taels. The silver coins were also marked with year numbers.

Four hundred heavy ones were piled on the bed, and the remaining ones were one, two, two, five, or ten taels. There were also five hundred thousand copper coins, which looked like fifty taels, all of which were exchanged by Ye Chanyi.

They were all piled on the bed, taking up a lot of space.

"Sister, start counting!" Yu Muyun looked at the three of them.

"number?"

"Yes, count how many there are in it, how many large silver ingots, how many small ones, how many copper coins, how many do they add up to!" Yu Muyun nodded.

The three of them looked at each other and began to count the money together.

The speed at which the three of them count money is different, and the number of the last person is different.

"It's all different!"

"Then let each other know their numbers, and then add them up together!"

The three of them wrote and calculated again, and finally figured it out.

"Is this the account collected today?" Tao Suxin reacted first.

"Yes! The prices of third-class fabrics at home vary, and the prices have also increased this year. The three sisters will calculate the fabrics and prices sold out this year, and see if the final calculation is consistent with today's accounts! "Yu Muyun handed over a notebook. The notebook was full, including the amount of fabrics coming in and out this year and the grade of fabrics.

The three of them rummaged around and did some calculations. Yu Muyun put the large silver ingots into the box, placing them neatly at any distance between them. Seeing that there were more and more in the box, Yu Muyun's face His smile grew bigger and bigger. After placing a large box, he also packed a small box.

After placing the big ones, I started to place the small ones. I put some twelve or five taels in, and then took out all the remaining ones from last year. I integrated a few large silver ingots into them. I took out all the small ones and put them in the box I have been using. Inside, it will be used as funds for next year.

It took two small boxes to install them all, but the three of them haven't finished it yet!

Yu Muyun walked over and saw that they were adding up the numbers one by one. In the past, they were given monthly deposits. The calculation was faster when the amount was small, but when the amount was large, the calculation became slower.

Now that I think about it, arithmetic here can basically only be learned in a higher school year. Basically, you have learned the literature, politics, and law that are basically required to be tested. Arithmetic is rarely learned. Basically, it is only for those who are interested, or who are in high school. You will learn arithmetic only when you improve your knowledge in the later period. Basically, most of the officials in the current dynasty cannot learn arithmetic, except for a few people in places like the Treasury and the Ministry of Rites who do learn arithmetic.

Yu Baiqing has read the most books in the family, but he can't do arithmetic and has basically never read them.

"This is very slow!"

"Twenty taels of cloth, multiplied by ten pieces of this cloth, is two hundred taels! Twelve taels multiplied by ten pieces of cloth is one hundred and twenty taels, and the same goes for fifteen taels!" Yu Muyun used charcoal pencil Wrote it in his notebook.

"Yes! Ten horses equals two hundred taels. Why?" Yu Zhuqing looked at Yu Muyun and asked.

"Look, if I add them up one by one, it will be very slow! If I use the multiplication method to calculate, it will be much faster!" Yu Muyun looked at a few people. Didn't he write the multiplication table before?
