Chapter 213 Mathematics Test

Shang Ruonan sat behind the bookcase, and two small tables were set up in the middle, and some paper and pens were also placed.

Shang Ruonan sat down, these two younger sisters are still young, but they should cultivate some basic knowledge since they were young. But there are a lot of people in this room today. Shang Ruo Nan when they don't exist. Only said to the two sisters:

"I'm going to talk to you today about some counting things, because I want someone to help me do some counting things. That is, they say bookkeeping, to be a good bookkeeper, you must first understand all the numbers and the relationship between the numbers. Be able to settle accounts. ”

"For example, if we sell a piece of clothing, you two should also know what we have in our ready-to-wear store. For example, Sixth Sister, the dress on your body is sold for three taels of silver in the ready-to-wear workshop. How much do you say we earn? ”

"Earn three taels!"

Old Wu Silan suddenly burst out of a sentence. Lao Liuwanglan stretched out her hand and patted the fifth sister and said:

"You're wrong, what about this clothes and cloth, this cloth was bought back and used the capital."

"Oh, yes, that's the money for this cloth."

It seems that the fifth sister is not so detailed. Shang Ruonan asked the sixth sister again:

"Do you think Fifth Sister is right?"

"I think there should be some things to be deducted, and the needlework for this dress is bought, and it should be counted as the cost."

Wanglan looked at her clothes, in addition to the cloth, there were threads.

Shang Ruonan nodded and said:

"Anything else? Can you still figure out how much this dress will cost? ”

Wanglan tilted her head again, thought about it again, and said:

"Fourth sister, does the salary of the person who makes clothes count?"

"Naturally! That's artificial money. Naturally, it should be included in the cost of this dress. Can I think of anything else? ”

Wanglan thought about it again, shook her head, and said that she didn't expect it.

Shang Ruonan nodded and said:

"Sixth sister is very smart, she can think of artificial money, but artificial money is not just the person who makes clothes, for example, your clothes are drawn by me, so I used my brain to think and my hands to draw. I also contributed to this dress, so it should be counted as my labor money. ”

"This is your clothes made in our house ourselves, if it is clothes that are sold in a store. That's the rent for that store. Also, if the dress is bought back in another place, you have to count the shipping money for the clothes sent all the way. ”

"These are all to be counted in the cost of this dress."

"So, although you say that this dress is sold for three taels of silver, we can't make three taels of silver, and after removing these capitals, the rest can be regarded as earning. It's just a gross account, you're a businessman, and you have to expect some lost money. ”

"For example, to make this dress, it is considered that only eight feet of cloth are used, but is eight feet of cloth enough? It's not enough, because when it is cut, some of the corners and corners can't be used, so it's lost, but it's in the cost of this dress, because it's the same cloth. ”

"Also, if two pieces of clothing are made from the same piece of cloth, one can be sold, but the other cannot be sold. Then, the cost of the remaining piece of clothing will also increase the cost of another piece of clothing. In this way, the amount of money that can be made by this piece of cloth will be reduced, and it may be lost, don't think that you will make money when you sell one, but you will lose another piece. ”

Shang Ruonan told his sister the truth. Sitting on the side as a fun listener, the more Murong Hou Ye listened, the more surprised he became, usually, he didn't notice so much, a piece of clothing, can calculate so many accounts.

It seems that each line also has some characteristics of its own line.

After talking about the cost of this dress, Shang Ruonan said again:

"I'm talking to you about this today, just to let you know that we are a merchant family, what we do, what we have to calculate first is the capital, how much we invest, and the money we may earn may be very little, but don't be blinded by some numbers, at first glance, three taels of clothes, buckled eight dollars of cloth, earned more than two taels of silver, not like this, this dress, we may not be able to earn one or two."

The two younger sisters listened dumbly, and asked if they understood, and the fifth said:

"Fourth sister, how do you know so much?"

"I usually understand it when I think about it myself, these things are all thought out in daily life."

Shang Ruonan said again:

"To be able to do some numbers, we have to learn some simple calculations, not just the ones that are passed down by word of mouth, but also a lot of calculation skills. Now I'm going to ask you a simple calculation question. From one to ten, how many are there? ”

For a while, the masters and girls in the house, as well as the clear water and breeze standing at the door and listening, also bowed their heads and counted, and most of them were counting their fingers.

"Whoever counts it out first, says it first."

"Sister, I've figured it out."

Wanglan shouted.

Everyone looked at Wanglan. Wanglan says:

"It's fifty-five."

"That's right! Wanglan is very good! ”

"Why are you so fast, I don't have enough fingers, I'm still counting."

"You are stupid yourself, there are simple ways, one plus nine, two plus eight, three plus seven, four plus six, it's four tens, and there is a five and a ten, which is fifty-five."

Shang Ruonan laughed and said:

"Yes, the fifth and sixth know how to use it, you can only use your fingers. How stupid! ”

Shang Ruonan's sentence was really stupid, so that the Hou Ye who hid his fingers in his sleeves and counted, Shang Lin who was sitting on the side and counting, and the breeze at the door, were all stunned, he was stupid!

Shang Ruonan said:

"There's something to be learned from. For example, from one to nine, you are given a grid, and there are three grids horizontally and vertically, so that you can put numbers in it, so that the number obtained by adding up the numbers in each row, column, and each diagonal line is a number, do you make it? ”

As soon as Shang Ruonan finished the question, Uncle Gen came to the door and said:

"Young master, there is a word from the ready-to-wear shop that someone wants to order clothes, saying that he is from Beijing, and he wants you to go and see it for himself."

Shang Ruonan frowned and said:

"Okay, get me a carriage. I'll go right away. ”

Turning around, Shang Ruonan told the sixth sister and the fifth sister:

"This question, you go back and think about it first, and then I will go back and say, I will go to the shop first to have a look."

When the master was about to leave, Lilac immediately stepped forward, sorted out the pens and paper that the master was going to carry, put them in a small cloth bag and carried them. Peony took a thin cloak and put it on the master, although it was early spring, but there was still a little cold, the master's body was weak, and now the peony took over all the dressing.

Seeing that the young family was going out, Shang Lin and Mu Fang stood up and resigned. Si Lan and Wang Lan also got up and went back to the backyard under the escort of the girl, and they still had to complete the question from the fourth sister, and the Marquis of Murong also stood up and said:

"I'm back home, too."
