Younger sister? What did she come over for?

Suning felt a little strange, but 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: "Second brother! ”

A sense of pity suddenly rose in Suning's heart, and he couldn't stand the cuteness of children, especially his own little sister, where did Suning have resistance? Helplessly, he smiled and pushed Su Xiaomei away, scratched Su Xiaomei's little nose and said, "What are you doing here without rest so late?" If you think you have nothing to do, find A-Niang to teach you female popularity, but you are not allowed to be idle! ”

Su Xiaomei was not happy when she heard it, and pursed her mouth and said coquettishly: "Where are people idle?" People don't want to learn what female red is! I'm bored to death, it's very difficult, second brother, you don't know, these days, A-Niang has taught other people to learn from Nu Hong, and she has stabbed several holes in other people's hands, but it hurts. After speaking, Su Xiaomei raised her little hand and put it in front of Suning, with an expression of crying if you don't hurt me.

Suning was helpless for a while, Su Xiaomei was still a little estranged from herself when she first recognized each other, but with the passage of time and the temptation of the food she made, these estrangements have completely disappeared, and now Su Xiaomei is the closest to herself in the whole family, and as soon as she comes home, she is the first to jump out and run out to greet her is Su Xiaomei, at first I thought that Xiaomei was very quiet, who knew that the closer Su Xiaomei's fierce and ghostly nature was, the more exposed it was.

For this eccentric little sister, Suning has no way at all, originally wanted to educate Su Xiaomei according to the template of ancient women's gentleness and grace, so as not to marry in the future, who knows that this is just the beginning Su Xiaomei pouted her mouth and sold cuteness to disintegrate her offensive, making herself very passive, and she has no ability to resist, Suning is indeed too spoiled Su Xiaomei, basically she responds to her needs.

Looking at Su Xiaomei's white and tender little hands with a few more red wounds, Su Ning also felt a little distressed, several years of labor in the field have not left any traces on Su Xiaomei's white and tender hands, but it has only been a few days, and there are these scars on both hands, is Su Xiaomei really not suitable for these things? Is it necessary for me to redraw the scope of Su Xiaomei's growth?

These days, Suning has already seen that Su Xiaomei is not a standard good wife and mother, but a lively person who is not satisfied with the status quo, she is definitely a type that can stand without sitting, she is a ghost, she looks weak, and she is strong inside, such a woman is a strange woman in ancient times, a generation of heroines in martial arts novels, and a strong woman in modern times.

"Alas! Jing'er, you don't want to be a girl, what do you want to do? If you are a man, you can still go to the army to gain fame, but if you are a woman, there is no such thing as a woman in the army in Datang, and the second brother will never allow you to join the army, it is too dangerous, absolutely not. Suning still decided to say it to death, and she must not let this energetic little girl do anything out of the ordinary.

Su Xiaomei's eyes were red, her mouth was pursed, and she saw that her tears were about to fly down three thousand feet, which made Suning anxious, if she cried, but it was an endless ending, Suning was most afraid that the girl would cry, so Suning hurriedly said: "Jing'er is good, Jing'er doesn't cry, Jing'er, as long as you don't think about dancing knives and guns, what do you want The second brother will promise you, okay?" You can do whatever you want, just don't dance with knives and guns, I don't like the second brother of the female red to go and tell A-Niang, is it okay not to learn? ”

The strong embankment was immediately built, and the tears quickly disappeared, and the circles under her eyes immediately returned to their original state, and Su Xiaomei immediately showed a bright smile: "Second brother is the best!" Jing'er knows that the second brother loves Jing'er the most, then the second brother, can Jing'er help you take care of this restaurant? ”

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

Su Xiaomei looked serious: "That's right, that's right, didn't the second brother say that he wanted to build a restaurant?" And just now Jing'er heard the second brother outside the door say that there was no candidate for haode, could the second brother not find the shopkeeper who managed the restaurant? Jing'er can! ”

I'll go! Fang Cai himself just said that, and was heard by the little sister? Do you still say that you want to be a restaurant shopkeeper? What international jokes? Twelve-year-old Lori goes to be a restaurant shopkeeper? A child prodigy or a child prodigy or a child prodigy? Suning looked at Su Xiaomei with a tangled face, then squatted down to look at Su Xiaomei, stroked Su Xiaomei's cheek and said: "Little sister, this is not a joke, it is not a trivial matter, it is a big thing, a big thing, the second brother himself is not completely sure, and he still needs to carefully consider and work hard, what else can you do at such a young age?" Do you know what a restaurant manager needs to do? ”

Su Xiaomei pursed her lips and looked unhappy: "Hmph! The second brother underestimated Jing'er too much! Isn't the most important thing for a restaurant manager to manage accounts? ”

Suning smiled helplessly: "It is necessary to manage the accounts, of course, you can also call some bookkeepers to do it, the shopkeeper can calculate the balance every month, and you don't need to do everything, but the management of the cook, the doctor (that is, the second child of Datang), the management of the restaurant, the source of things like vegetables, meat, wine, and some guests, but they all need to be done by the shopkeeper, where can you do it as a little girl?" Still not bullied to death? ”

Su Xiaomei frowned and said, "Whoever dares to bully me, I will beat him until he dares to bully me!" I don't care who he is! Whoever dares to make trouble in the restaurant, I want him to look good! The cook and the doctor must be obedient and obedient, and if they are disobedient, they will be beaten and thrown out of the restaurant! Whoever dares to cheat on the account will be sent directly to the government, and you can arrange the second brother of vegetables, meat, wine or something. ”

Su Ning was a little surprised in her heart, Su Xiaomei's momentum was indeed good, she was quite resolute, and her words did look so good, but Suning would never let Su Xiaomei show up to do these things, besides, does Su Xiaomei know mathematics? Will it settle accounts? Can you understand the fake made by Mr. Bookkeeper?

So Suning straightened his face and said: "Little sister, what you said is only part of it, although it makes sense, but it is not enough, and most importantly, do you know how to do accounts?" Do you know how to do arithmetic? How to calculate all the expenses and income of a restaurant, will you? This is a must-know thing for the shopkeeper, and if he can't, he can't be the shopkeeper. ”

I thought that Su Xiaomei would retreat in the face of difficulties, but who knew that Su Xiaomei smiled: "Second brother! Of course they will! ”

Suning was shocked: "What? Will you? Do you know how to do arithmetic? ”

Su Xiaomei nodded and showed a proud smile: "Of course people will!" ”

Suning wondered, "What will you do?" Who taught you? Big brother and aunt can't do it! ”

Su Xiaomei pointed to Suning's desk: "Actually, a few days ago, when Jing'er helped the second brother tidy up the desk, I saw those things written by the second brother, those one, two, three, four, addition, subtraction, multiplication and division of four or something, it's very simple, Jing'er will see it at a glance, what one plus one and two minus one by five times two, everyone has written it correctly, second brother, you can't help but agree to others!" ”

Suning widened his eyes, he did write some of the basic numbers that he was going to teach to Changsun Chong Li Chengqian a few days ago, that is, the four operations of addition, subtraction, multiplication and division, which are currently the most practical and the most used, including probability and statistics, etc. are very practical mathematical content, as for the triangle cylinder, which involves the field of architecture and the field of pure theoretical research, it is not within Suning's scope of consideration, Suning's own mathematics is not good, addition, subtraction, multiplication and division are enough, and the rest is written in a book to pass on to future generations. Let someone else do the research.

But even those contents are absolutely unheard of for an ancient person who has never been exposed to modern mathematics, let alone learn it, the last time he personally taught mathematical knowledge to Li Chengqian and the other four people, they still know a little bit about it, and now it will only add one to equal two, Su Xiaomei learned it by herself only by relying on some things she wrote? Is my little sister a math genius?

Suning pulled Su Xiaomei to his desk in disbelief, took out what he had written down and asked, "That's it?" Will you be? ”

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

Suning is a little convinced, Xiaomei will not deceive herself, and there is absolutely no reason to deceive herself, not to mention that the truth is in front of her, Su Xiaomei would do such a stupid thing? But Suning still decided to take a test for Su Xiaomei, this matter is too big, if you don't take a test for Su Xiaomei carefully, Suning really can't believe that Su Xiaomei can accept modern mathematics in such a short period of time, Su Xiaomei is literate Suning knows that Wang and Su are literate, so Su Xiaomei is also literate, but literacy does not mean that you can understand modern mathematics and Arabic numerals!

"What is fifty-three plus ninety-two?" As soon as Suning came up, a relatively large number came out, and Su Xiaomei raised her eyebrows and smiled: "One hundred and forty-five!" ”

Suning was taken aback, and then asked, "What is thirty-three divided by three?" Su Xiaomei put on a soeasy look: "Eleven! ”

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

"How much is twenty-eight divided by seven?" "Four! Second brother, can you have some difficult questions? The arithmetic problems you wrote down on paper have already been figured out. ”

Suning looked at Su Xiaomei in surprise, although these things are very easy, and the second-grade students will almost be able to do it, but an ancient person can understand the four operations just by relying on these four operations written down by himself without a mathematical foundation at all, including multiplication and division, which do not yet exist, Suning is really a little hard to believe.

"Little sister, did you learn it after reading everything that your second brother wrote?" Suning asked seriously, Su Xiaomei nodded: "I've read it, I've read it all, and then I've written out all these questions, it's very simple!" ”

Although these questions are simple, according to the current level of Chinese parents wishing their sons to become dragons and daughters to become phoenixes, four-year-old children will also do it, but this is ancient, even basic Chinese literacy can not be popularized, let alone mathematics? Mathematics is still a niche discipline today, although there are many people who understand it, and there are many people who use it, but it has not formed a system at all, and it does not have inheritance at all, so it will be completely replaced by modern mathematics teaching, leaving only some classic problems like chickens and rabbits in the same cage.

Su Xiaomei is really a genius? Is this her natural specialty?
