Back home, Chan was taken aback. It's very shocking to pile up a book that is tall and human. Chen couldn't help asking, "Do you still have money?" ”

Ting Fang said with a smile: "I met the senior brother, the list he gave was not well printed, and it was only a hundred texts. Some of them are not expensive. He said that arithmetic is very unscripted, not to mention expensive, those talents may not be able to copy accurately. ”

Chen asked suspiciously, "Which senior brother?" ”

Mother Hu replied: "The second master accepted the son of the Dingguo family. ”

Chen frowned and said, "How did you meet him?" The outside world said that he was not good, and he wandered around all day long without doing his job. worshiped the second master as a teacher, and I never saw him come often. Now the Four Books and Five Classics are not as good as our four sisters. The second sibling often complained that he had ruined his master's reputation. ”

Ting Fang said: "His mind is not on that, but he likes arithmetic and institutions." Heng and vertical is the son of the world, not all the way with us, what did you do after learning the four books and five classics? ”

Mother Hu also said: "Looking at the etiquette, the speech and demeanor are quite elegant, but there are some crazy demons, looking at our girl's eyes shining." ”

"Huh?" Chen said, "What kind of light?" ”

Mother Hu smiled: "Mrs. doesn't know, the girl stopped people as soon as she made a move." I can't read and speak. The topic suddenly turned around, "Mrs. hasn't seen Xu Shizi yet, right?" He is really handsome, better than when our lord was young. ”

Chen smiled: "His mother was a beauty when she was young, and she wanted to be like his mother. ”

Ting Fang asked: "Was the Duchess of Dingguo very good-looking when she was young?" "Didn't you think it looked like a fairy last time? However, our big brother is so good-looking! There is no problem at all with a casual Internet celebrity in the future.

Chen said: "That's the stepmother, his own mother is long gone." He pouted again, "My uncle's family is out of tune." ”

Ting Fang was very suspicious, the inattention in Chen's mouth was probably not in line with the aesthetics of civil officials, right? Xu Jingchang is okay, at least he is familiar with books, but science students are not allowed to be in the world now. But those had nothing to do with her, so she diverted the topic and said, "What about the big sister?" What the hell is she busy with, I don't see her in the town. ”

Chen patted his head: "Look at my memory, I was about to ask you." Your eldest sister recently learned to settle accounts, and the family was fine, but when she arrived at the field shop, it was a mess. Our family's account room is invited from outside, but it is still a man, and it is not good to teach from time to time. You've bought so many arithmetic books, let's see if there are any acres of land. ”

"Yes! Much more. "The main function of ancient mathematics is to settle accounts, Ting Fang just swept it, and remember. He dug out the "Nine Chapters of Arithmetic" from a pile of books, turned to the second chapter, pointed to the cover, and said, "Talk about how chestnut rice is converted proportionally." There is also the sixth chapter, 'Losing Evenly', which talks about how to set taxes to be reasonable. Then there is Chapter 7, 'Profit and Deficit', which can be counted as profit and loss. I also saw the eighth chapter, "Equation", co-authored "Equation" is an ancient saying, not a foreign word at all. Big brother, you scumbag! I can't react when I hear the equation, I can't react! On the contrary, the Tianyuan style is more secluded, right? Literati, literati, I have to do the four ways of writing fennel beans, it's really boring.

Chen is a math scumbag, and her old man is the scum of the scum when she plays Go. The so-called qin, chess, calligraphy and painting, the other three are very good, but Go, if Tingfang is willing, she can kill her at any time. Counting acres and the like has never been black-eyed, and the dowries are all simple and rude shops and Zhuangzi, all of which are rented to others, and she only cares about the general account. Ting Fang is about to die of worry for her, what can she do if she inherits the Ye family's ancestral property in the future? It seems that the second aunt and the third aunt are all math scum, and it is not good to play mahjong and count cards, oh, why is she not a man! Lesbians are good at liberal arts, and they can't take the imperial examination, so they might as well settle accounts. Old lady, your vision of finding a daughter-in-law is also stunning, where is your usual shrewdness?

As everyone knows, the old lady is being scratched by Ting Yao's sorrowful wall. What a simple calculation of farm property, the usually clever girl is suddenly stupid! Isn't it just a rough estimation of the annual harvest based on the weather, and the provincial people have fooled the past? Why didn't she understand?

The old lady has no experience in raising a daughter, and when she arrived at Ting Yao, she realized that some people really can't learn arithmetic. You can't let a girl who can't settle accounts marry into her in-law's family and be bullied, right? couldn't help but complain to Chen's mother in a low voice: "It's just a biological girl, and she doesn't care at all, and she won't be what she is today." I can marry the shop and just collect rent, but how can she show her ability when everyone knows what she does? I want her to marry better, at best, to marry a gravewoman. "The clan woman is very tired, but she also has a lot of resources. Everyone asks for her, and her own children are very easy to get ahead. Otherwise, who would want to let his girl suffer that sin?

Du's mother received the news that Ting Fang had moved back from the book, and explained: "The eldest lady is silent, and she knows it in her heart." The fourth girl went out and moved a car to study and go home. ”

The old lady sneered: "She knows a fart!" Eighty percent of it is your four girls who make their own decisions. Hey? A car of arithmetic? ”

Mother Du nodded and said: "I am closing the money with the eldest wife, it is not my wife's order, how dare she be the master." ”

The old lady rolled her eyes: "I think she is very daring, your eldest lady is used to children, give whatever you want." Go and call the four girls, I don't believe it, none of the seven girls in the family are like me! ”

Du's mother couldn't help but smile and retreated, calling the girl to invite someone. The old lady paced in front of Ting Yao again, and finally stumbled to figure out what the manor came out of, but how to adjust it in the coming year was scattered, and sighed deeply.

Ting Yao's face turned red: "Old lady......"

The old lady was so tired, she waved her hand and said, "It's okay, I was negligent, and I should be the one who should be taught." I'll do the math with you again. ”

Hearing the old lady's call, Ting Fang threw the settlement to Chen, and jumped into the old lady's house and saw the eldest sister who was half-crippled by mathematics. Blessed with the old lady, probe to see Ting Yao's practice, that group of black ink balls, very Chen Gong's demeanor, you are really cousins and brothers!

The old lady raised her eyebrows and threw a piece of paper over: "Count! ”

Tingfang looked at the title, Emma, calculate the depth of the ditch, and abused countless elementary school students back then. Water Pipe Inlet Upgrade. She was really sleepy and met the pillow, and she was still thinking about how to explain math to her elders. Chen is not afraid, as the old lady understands, that thing is used to children, and it is very easy to deal with. But the Ye family lives together in three rooms, and many times it is too flamboyant and easy to get into trouble. Unexpectedly, she hadn't found a way to confess, and the old lady had taken the lead. Go out. The problem of water pipes and water inlet pipes can be solved simply at the elementary school level. However, although the primary school version is called application problems, the scope of application is actually very limited, because there are not too many variables considered, and the main thing is to train children's mathematical thinking. When I get to college, I can do a lot of actual combat.

As we all know, the engine of a game contains a lot of calculations, the most important of which is the physics engine. Tingfang definitely can't write an engine out of thin air, her main job is to continue to write code on the existing engine according to the company's needs. The game has a certain amount of simulated reality, and she strives to fight her way up the ladder in the IT industry, where the ratio of men to women is strictly imbalanced. In fact, she did come out, in an industry that is almost extremely sexist, convincing the IT men of the whole company that it was her most glorious moment, and it is not an exaggeration to say that it is the peak of her life. Even after nine years, the calculation ability of such high-intensity training still leaves a very deep imprint. An introductory calculus problem that is not demanding will not take long to solve.

Old Lady: "......"

Ting Fang blinked her big sparkling eyes and asked, "What else is it?" ”

The old lady looked at Ting Fang in disbelief, stupid and stupid, and awesome! She asked herself to be good at settling accounts, but she didn't know the algorithm of the ditch, but when she copied the question from the book, the ignorant little guy copied a similar problem book and sent it in, she put it on the table casually, and when she threw it to Ting Fang, she knew that it was wrong, and she was trying to change the question, and Ting Fang was already solving it. Before she could understand what Ting Fang was writing, she had already figured it out.

Ting Yao was calculating a headache, and seeing that Ting Fang seemed to be very calculating, she pushed the share on her table in front of Ting Fang: "Don't count the useless, count this." ”

Ting Fang twitched the corners of her mouth: "Sister, water conservancy is very important, why is it not useful?" ”

Ting Yao said frantically: "If I want a girl's family to know what water conservancy, you can calculate the household account for me." ”

Ting Fang took it and took a look, it was really a household account. Funny, I took the pen and stood clearly. I feel a pity in my heart, just from Ting Yao's writing articles, I can see that his logical thinking is not weak, but he is not trained when he is young, and Bu Yi is too nervous when he encounters an unfamiliar subject, and he can't learn well when he is afraid of difficulties. In fact, in ancient times, everyone was considered a family, and elementary school mathematics was almost inseparable.

Ting Yao looked at Ting Fang with a complicated expression, tossed her things for two days, and didn't need a cup of tea in Ting Fang's hands. When I was young, I knew that Tingfang was smart, but I didn't expect to be so smart. It's inevitable that my heart will be sour.

Ting Fang put down the pen and said to Ting Yao very seriously: "Big sister, is it difficult to do things in the world?" If you do it, it will be easy for those who are difficult; If you don't, it's easy and it's hard. Is it easy to learn? If you learn it, it will be easy for those who are difficult; ”

Ting Yao's eyes widened, only to feel deafening, and after a while, she said: "It is easy for those who are difficult, and it is difficult for those who are easy...... Fourth sister, hello Wencai. "It's really good for everything.

"Gah!?" Isn't this the original sentence in the nine-year compulsory education Chinese textbook? Could it be that she she accidentally plagiarized? ①
