Enter the Room

Yuan Yunzhong's voice was neither high nor low, and could even be called gentle, but in everyone's ears, people could really feel his seriousness - he really didn't care about killing people, but felt The Spring Festival is coming soon, and it is unlucky to have someone die in the house.

Everyone couldn't help but shudder.

Song Jiuxue was very excited.

When Yuan Yunzhong hugged her and headed to Yin Yu Tang without looking back, she even made a face at Song Sanliang and others like those children who relied on and were doted on.

After returning to Yin Yu Tang, Yuan Yunzhong carried her directly into the study, placed her on the large desk where he usually wrote and drew, took ointment and applied it to her himself.

The smell of the ointment is a bit pungent, but it feels refreshing and cooling after applying it on the face, which is very comfortable.

Song Jiuxue held her head up obediently and let Yuan Yunzhong apply medicine to her.

Yuan Yunzhong's heart also softened.

He asked Song Jiuxue: "Who taught you the formula for memorizing an abacus?"

Song Jixue said proudly: "No one taught me, I learned it myself."

She was still afraid that Yuan Yunzhong wouldn't believe it, so she explained: "That year, my father taught the second sister an abacus. The second sister didn't learn it for a long time, but I learned it as soon as I listened."

Then she memorized the formula: "When one goes into one, when two goes into two...two times down and five goes into three, three times down and five goes into two...four goes out to six and goes into one, five goes out to five and goes into one...two and one add to make five." …Six retreats and one return four…”

Yuan Yunzhong's eyes became brighter.

He touched her head gently and said, "Let me test you."

Song Jiuxue nodded repeatedly, as if "you test me quickly, you test me quickly".

Yuan Yunzhong said: "Seven plus fifteen, what does it equal?"

Song Jixue didn't even think about it, and immediately said: "Of course it's twenty-two!"

Yuan Yunzhong asked again: "What about thirty-six plus forty-two?"

This time Song Jiyun answered faster: "Seventy-eight!"

Yuan Yunzhong said: "One hundred and fifty-three plus three hundred and seventy-six?"

Song Jiuxue: "Five hundred and twenty-nine."

"Five hundred and sixty-nine minus two hundred and ninety-seven?"

"Two hundred and seventy-two."

…

Yuan Chongzhong added up again and again, and finally muttered: "Twenty-four thousand three hundred and fifty-four minus nine thousand six hundred and eighty-five, add nineteen thousand seven hundred and eighty-three, minus twenty-six thousand Three hundred and forty-seven?”

This time Song Jiuxue thought for a while, but only for a moment: "Eight thousand one hundred and five."

Yuan Yunzhong was silent for a moment.

Song Jixue asked anxiously: "Did I make a mistake in my calculation?" Then she immediately denied: "No, I couldn't have made a mistake in my calculation." Then she asked him: "Did I not calculate fast enough?" Then she complained angrily. : "That's because you don't have an abacus here. If you had an abacus, I would calculate faster."

"No!" Yuan Yunzhong smiled at her, his dark eyes were like stars, and said, "I was frightened by the snow! I have never seen someone who can calculate faster and more accurately than you. A little kid.”

"Of course!" Song Jiuxue became happy again, and she chirped, "In the past, when my father took the test for my second sister, I would often get it before my second sister could do it.

"Song Tianbao and Song Tiancong were even more stupid. Once we went to buy candy. The big candy man cost five cents a piece, the small candy man cost three cents a piece, and the three candy bars cost a cent. We pooled together a hundred cents, and Song Tianbao wanted to buy it. Big Candy Man, Song Tiancong wants to buy Little Candy Man. I said, we can buy twelve Big Candy Man, four Little Candy Man, and eighty-four candy bars. With Song Tianhui, we can buy three Big Candy Man each. , a little candy man, twenty-one candy bars. But they all ignored me.

"Song Tianbao bought ten big candy figures, and Song Tiancong bought ten small candy figures. Then he found that there were two more big candy figures and two more small candy figures, and Song Tianbao also spent twenty cents more than Song Tiancong. Song Tiancong was not convinced, and they started fighting!"

Yuan Yunzhong listened to her words carefully and agreed: "They are all quite stupid."

"That's right!" Song Jiuxue got the approval and became more and more enthusiastic, saying, "Brother-in-law, I will also test you."

Before Yuan Yunzhong could speak, she already said: "There is something whose number I don't know. Two of three and three, three of five and five, two of seven and seven, what is the geometry of the thing?"

Yuan Yunzhong smiled slightly and said: "Twenty-three."

"Wow! Brother-in-law, you are so awesome!" Song Jiuxue exclaimed and asked Yuan Yunzhong another question, "Hundreds of rabbits walked into the camp, and many men and women fought over them. It was difficult to catch them all, and four and three people started You have to stop." She blinked and looked at Yuan Yunzhong, "Brother-in-law, do you know how many people go to catch rabbits?"

That cunning look is actually 70% or 80% similar to Song Jiuyun.

Yuan Yunzhong couldn't help pinching her cheeks, which still had some baby fat, and said with a smile: "Seventy-five people!"

"Brother-in-law! Brother-in-law!" Song Jiuxue was so happy that she didn't know what to do.

Yuan Yunzhong asked her: "Who else knows that you are good at arithmetic?"

Song Jiuxue shook her head, her mood suddenly felt a little low, but she still defended her family: "The eldest sister is usually very busy, my mother is pregnant with my little sister, and the second sister... She said that girls can read ledgers and know how many cases there are in each month. No matter how much you spend, it’s enough.”

Most girls are like this.

But Song Jiuyun is different.

Of course Song Jiuyun's sister can be different.

Yuan Yunzhong comforted her: "What your second sister said is wrong. Even if you are a girl, as long as you are powerful enough, like your eldest sister, you can do what boys can do. Look, your eldest sister is in charge. Is it the Song family’s business?”

"Yeah, yeah!" Song Jixue's eyes turned into moon buds with smiles, and she nodded repeatedly, "My eldest sister is very powerful! But, brother-in-law, you are also very good."

Yuan Yunzhong smiled, thought for a while, and said, "Do you want to continue learning arithmetic? If you want to learn, I can hire a teacher for you then."

Song Jiuxue was a little confused and said, "But what did I learn to do? My second sister said that if I learn nvhong, I can make clothes, wear them beautifully, and keep warm; if I learn to cook, I can eat whatever I want. You can also cook it for my mother, eldest sister and me. What can I do if I learn arithmetic?"

She tilted her little head and asked Yuan Yunzhong: "Do you want to be an accountant? But our family already has an accountant. People from outside will not invite me. If I become our accountant, won't our accountant have to be Resigned? Our family can't afford to hire idle people, right? Wouldn't that mean we have to pay another salary?"

Yuan Yunzhong laughed loudly and said, "Then you can help your eldest sister manage the kiln factory!"

He used an analogy: "Look, if you have a sum of money, whether you lend it to others or store it in a bank, there will always be interest. If you buy the money and keep it in the clay, then in the clay Before it turns into porcelain, it can just sit there and earn no interest at all.

"But if you don't buy mud and save it, you can buy as much mud as you need. If you buy less, the mud dealer will only sell it to you at the retail price, and the retail price is much more expensive than the wholesale price. Every kilogram of mud If the ingredients are spread on porcelain, it will be more expensive than other people's.

"So, you have to carefully calculate how much mud you need. It can't be more, and it can't be less. This is not something that ordinary people can calculate clearly."
