Little sister? What did she come here to do?

Suning felt a little strange, but she still got up and walked to the door to open the door. As soon as the door opened, Su Xiaomei threw herself into Suning's arms with a smile on her face: "Second brother!"

Suning suddenly felt a sense of pity in his heart. He couldn't stand the child acting cute and cute, especially his own little sister. How could Suning have resistance? He smiled helplessly and pushed Su Xiaomei away, scraped Su Xiaomei's nose and said, "What are you doing here if you don't have a rest? If you feel you have nothing to do, ask your mother to teach you Nu Hong, you are not allowed to be idle!"

When Su Xiaomei heard this, she was upset and pouted and said in a coquettish voice: "Where are you idle? I don't want to learn from Nu Hong! It's so boring that it's very difficult. Second brother, you don't know that my mother taught her to learn from Nu Hong these days, and it hurts." After saying that, Su Xiaomei raised her hand and put it in front of Suning, with an expression of crying if you don't love me.

Suning was helpless. When they first recognized each other, Su Xiaomei was still a little distant to her, but with the passage of time and the temptation of the food she made, these distant places have completely disappeared. Now Su Xiaomei is the closest to her in the whole family. When she got home, she jumped out to greet her was Su Xiaomei. At first, she thought that the younger sister was very quiet, but who knew that the closer she was, the more she was, the more exposed her nature was.

Suning had no choice but to this quirky little girl. She originally wanted to educate Su Xiaomei according to the gentle and sophisticated template of the ancient woman, so as not to get married in the future. Who knew that at the beginning, Su Xiaomei pouted and acted cute, she collapsed her offensive, making her very passive and had no ability to resist. Suning was indeed too doting Su Xiaomei, and basically agreed to her requests.

Seeing a few red wounds appearing on Su Xiaomei's white and tender little hands, Suning felt a little distressed. He had not left any traces on Su Xiaomei's white and tender hands for several years. But in just a few days, these scars appeared on both hands. Is Su Xiaomei really not suitable for doing these things? Is it necessary for me to redefine Su Xiaomei's growth range?

Suning has seen these days that Su Xiaomei is not a standard type of good wife and mother, but a lively person who is uneasy about the status quo. She is definitely a type of person who can stand and not sit. She is a ghostly and genius, looks weak and strong inside. Such a woman is a strange woman in ancient times, and in martial arts novels, she is a generation of female heroes, and in modern times, she is also a strong woman.

"Oh! Jing'er, what do you want to do if you don't want to learn from the girl's popularity? If you are a man, you can still go to the army to gain fame, but you are a woman. There is no such thing as a woman in the Tang Dynasty. The second brother will never allow you to join the army. That is too dangerous and absolutely not possible." Suning decided to say it to death, and he must not let this energetic little girl do anything out of the ordinary.

Su Xiaomei's eyes turned red, her mouth pouted, and tears were about to flow down three thousand feet. This made Suning very anxious. If she started crying, it would be an endless ending. Suning was most afraid of girls crying, so Suning hurriedly said: "Be good, Jing'er, Jing'er, don't cry, Jing'er, as long as you don't think about dancing with swords and guns, you can agree to you whatever you want? You can do whatever you want, but don't play swords and guns. I don't like the second brother of the girl Hong to tell her mother, wouldn't it be better if you don't learn?"

The solid embankment was built immediately, with a stance of rising from the ground, tears quickly disappeared, and the circles of eyes immediately returned to their original state. Su Xiaomei immediately smiled brightly: "Second brother is the best! Jing'er knew that the second brother loved Jing'er the most. Then Brother, Jing'er, would you help you manage this restaurant?"

Suning suddenly came to Sparta and it took a long time to come back to his senses: "Jing'er, what did you say? Restaurant? Do you want to manage the restaurant?"

Su Xiaomei looked serious: "Yes, right, didn't the second brother say that he wanted to build a restaurant? And just now, Jing'er heard the second brother say that there is no good candidate outside the door. Is it because the second brother can't find the shopkeeper who manages the restaurant? Jing'er can!"

I went! I just said that just now, and the little sister heard it. I also said that I wanted to be a restaurant shopkeeper? What international jokes are you making? A twelve-year-old little loli went to be a restaurant shopkeeper? A child prodigy or a child prodigy? Suning looked at Su Xiaomei with a confused look, then squatted down and looked at Su Xiaomei, touched Su Xiaomei's cheek and said, "Little sister, this is not just a joke, nor is it a small matter. It is a big thing. The second brother himself is not sure about it. He still needs to think carefully and work hard. What else can you do at such a young age? Do you know what the restaurant shopkeeper needs to do?"

Su Xiaomei pouted her mouth and looked unhappy: "Hmph! Brother Second is too underestimating Jing'er! Isn't the most important thing for the restaurant shopkeeper to manage the accounts?"

Suning smiled helplessly and said, "It is necessary to manage accounts. Of course, you can also ask some accountants to do it. The shopkeeper can calculate the balance every month, and there is no need to do anything. However, the chef, doctor (that is, the waiter of Datang), the management of restaurants, the source of food, meat, wine, and some guests' entertainment needs to be done by the shopkeeper. Where can you, a little girl, do it? Not being bullied to death by others?"

Su Xiaomei frowned and said, "Whoever dares to bully me will beat him so hard that he will not bully me! I don't care who he is! Whoever dares to make trouble in the restaurant will want him to be nice! The chef and the doctor must be obedient and beat him out of the restaurant if he is disobedient! Whoever dares to fake the books on the books will send him directly to the government, you can arrange it for the second brother, vegetables, meat, wine, etc."

Suning was a little surprised. Su Xiaomei's momentum was indeed good, she looked a bit decisive and she did look a little bit. However, Suning would never let Su Xiaomei show up in public to do these things. Besides, does Su Xiaomei understand mathematics? Can she settle accounts? Can she understand the fakes made by the accountant?

So Suning raised his face and said, "Little sister, what you said is only part of it. Although it makes sense, it is not enough. And the most important thing is, do you know how to make accounts? Do you know how to calculate the cost and income of a restaurant? Do you know how to calculate all the expenses and income of a restaurant? This is something that the shopkeeper must know. If he doesn't know, he can't be a shopkeeper."

I thought Su Xiaomei would give up, but who knew that Su Xiaomei smiled: "Second brother! Of course I can do it!"

Suning was shocked: "What? Do you know how to calculate the calculation?"

Su Xiaomei nodded and showed a proud smile: "Of course I can do it!"

Suning said in confusion: "What do you know? Who taught you? Neither brother nor aunt can do it!"

Su Xiaomei pointed to Suning's desk: "Actually, when Jing'er helped her second brother organize her desk a few days ago, she saw the things she wrote about, one, two, three, four, addition, subtraction, multiplication, division, and four operations. It's very simple. Jing'er can tell you at a glance. One plus, one, two, subtraction, one, five, and two, but they have written them correctly. Second brother, you can't help but agree to them!"

Suning stared widened his eyes. He did write some basic numbers that he planned to teach Changsun Chong and Li Chengqian a few days ago, that is, the four-point calculations of addition, subtraction, multiplication and division. This is the most practical and most used by most people. It includes probability statistics and other very practical mathematical content. As for triangular cylinders, which involve the field of architecture and pure theoretical research, are not within Suning's consideration. Suning's own mathematics is not good either. Addition, subtraction, multiplication and division are enough. Write a book to pass on to future generations, so let others study it.

But even those contents are absolutely unheard of for an ancient man who had never been exposed to modern mathematics, let alone learned it. Last time, he personally taught mathematics knowledge to Li Chengqian and the other four, and they had only a slight understanding. At present, he only knows one plus one equals two. Su Xiaomei learned it by relying on some things he wrote? Is Xiaomei a math genius?

Suning half-believed and half-doubtedly pulled Su Xiaomei to her desk, took out the things she wrote and asked, "That's all? Do you know what you do?"

Su Xiaomei smiled proudly: "Of course it will!"

Suning believed it a little. The little sister would not deceive herself, and there was absolutely no reason to deceive herself. What's more, the facts were right in front of her. Su Xiaomei would do such a stupid thing? But Suning still decided to take the exam for Su Xiaomei. This is too big. If she didn't take the exam for Su Xiaomei, Suning really couldn't believe that Su Xiaomei could accept modern mathematics in such a short time. Su Xiaomei knew that both Wang and Su were literate, so Su Xiaomei knew literacy, but literacy did not mean that she could understand modern mathematics and Arabic numerals!

"What is fifty-three plus ninety-two equal?" Suning came up with a relatively large number, and Su Xiaomei smiled: "One hundred and forty-five!"

Suning was shocked and then asked: "How much does thirty-three divided by three equal?" Su Xiaomei looked soeasy: "Eleven!"

"What is sixteen times four equal?" "Sixty-four!"

"Twenty-eight divided by seven equals how much" "Four! Second brother, can you ask some difficult problems? People have calculated the arithmetic problems you wrote on paper."

Suning looked at Su Xiaomei in surprise. Although these things are easy, students in the second grade of elementary school can almost understand them. However, Suning is really hard to believe that the four operations, including multiplication and division that do not exist yet, just because of the four operations he wrote, just by relying on the four operations he wrote.

"Little sister, you learned it after reading all the things you wrote by your second brother?" Suning asked seriously. Su Xiaomei nodded: "I finished reading, I read it all, and then I wrote down all these questions. It's very simple!"

Although these problems are simple, four-year-old children can do it according to the degree that Chinese parents hope that their children will become dragons and girls will become phoenixes. However, this was in ancient times, even basic Mandarin literacy could not be popularized, let alone mathematics? Mathematics is still a niche subject today. Although many people understand and use them, there is no system at all and is not inherited at all, so it is completely replaced by modern mathematics teaching, leaving only some classic problems like chickens and rabbits in the same cage.
