Ting Fang glanced at Xu Jiqiu, and didn't know why he had eaten gunpowder today. With a casual "oh", he asked, "And then?" ”

Xu Jiqiu: "......"

In terms of the thickness of the skin, all the girls in the audience are not as good as one ten-thousandth of Tingfang's, a painless provocation, and you are the one who lifts up. It is very common for the little girl's family to commit the second disease, which goes directly into the left ear and out of the right ear. However, Xu Jiqiu reminded Ting Fang, so Ting Fang smiled and asked the girls: "Do you sisters know how to draw a triangle with the same length on three sides?" ”

Women: Why did the topic of "......" suddenly turn around, is it okay to give a hint?

Tingfang, the most important thing in the IT industry is that technicians talk to planners, and there are always a few fights in the hospital a year when they are not clear. Liberal arts planners can never keep up with the thinking of technicians, and technicians never know what the hell the planners are talking about. After Ting Fang took out the technical backbone's housekeeping skills, a group of little girls had to be dizzy if they didn't faint, and it was up to you to see if you still wanted to name the words "Famous Crown Beijing".

Seeing that no one was talking, Ting Fang dipped his hand in the tea, drew a regular triangle on the table, and said with a smile: "It's like this, only I draw it casually, who knows how to draw it accurately?" ”

Basic geometry problems, the whole audience crashes. Ting Fang is really lonely as snow, and she doesn't even have a compliment. It can be seen that the bear child Chen Gong still has a skill, at least he will ask why. It's a pity that the black history of the bear child is about to catch up with China for 5,000 years, and today he was directly locked up in the West Courtyard and guarded by two healthy women, and it is absolutely impossible to get out.

Xu Jiqiu spoke coldly, and his eyes flew away; When Ting Fang spoke, she directly looked at mosquito coils. Ting Yao had no choice but to come out to the rescue, and said with a smile: "My sister is the most obsessed with being small, you are laughing." ”

The women are still mosquito eyes. The rumors are full of twists and turns, which are more exciting than the book. I saw Tingfang in Yan's house last time, I only thought that she was young and didn't know the world, but today I realized how she didn't understand the amorous feelings, and I couldn't figure out whether she was pretending or not. For a while, everyone was bored, Ting Yao Tingshan and Yang Yihe each pulled a few little sisters, and reluctantly turned the topic to food, clothing, housing and transportation, and the pavilion became lively again.

After a long time, Hou Jingrong clapped his hands suddenly: "How do you draw it?" I know that three chopsticks can be put out, but if I want to draw neatly, I really can't. Does my sister know how to do it? ”

Tingfang: "......" This reflection arc is a bit outrageous! However, Hou Jingrong was the only one who had a reflex arc at the scene...... The rest of them all have an expression that they have finally gotten rid of the problem of snake essence disease, why did you bring it up again, science and technology are prosperous, comrades!!

Although Ting Yao has been made up a lot of mathematics, she is outrageous, and when she sees mathematics, she has a headache and rubs her temples. said: "I can't get these anymore, why don't you call me." ”

Ting Shan sneered: "It's a pity that King Fu has gone home, otherwise it would be difficult for him." ”

Ting Fang smiled and shook his head: "He has watched "Geometric Original", so he can't help it." ”

Ting Shan's eyes widened: "Just the one in your house?" I flipped through it, but I didn't write it! ”

Ting Fang said helplessly: "The first page is written!" ”

Ting Shan said categorically: "Absolutely not!" "If you don't understand, you don't understand, you can start to memorize the memory of the children's skills from the age of three, and you don't remember all the books you have read, at least you have an impression. But the first few pages of the book didn't even have pictures, they were all words, and she remembered them very clearly.

Ting Fang sighed: "Third sister, when you played chess, you never memorized the formula, didn't you think about why the formula looked like that?" ”

Ting Shan laughed dryly, Ting Yao also laughed dryly, and Ting Lan even ...... The master who can only hang horns. But why did you turn to chess again?

Yang Yihe asked weakly: "The formula is the formula, what else is why?" ”

Tingfang: "...... girl, you will be born in the 21st century, and you will definitely fail mathematics.

Ting Shan jumped in front of him and shook Ting Fang and said, "Let's talk about the previous one first, I haven't seen anyone who can draw a triangle!" "Forced the topic back again.

Tingfang's kind-hearted prompt: "The third kilometer." ”

Ting Shan's mind was full of question marks.

Tingfang had to take out a thread from her purse, wrap a chopstick, and draw a circle with her hand as the axis: "Given any line segment, you can use one of its endpoints as the center of the circle, and the line segment as the radius to make a circle. ”

Ting Yao and Ting Shan nodded in unison, they had seen it.

Ting Fang drew another circle on the boundary of the circle, with it as the axis. The two circles overlapped. Draw a line in the middle: "Do you see it?" ”

Ting Shan shook her head.

Ting Fang wanted to continue, but Hou Jingrong said, "Slow! Think about it! ”

Ting Fang stood still. Half a day, Hou Jingrong also dipped his chopsticks in the tea, drew a triangle in the intersecting part, and asked with a smile: "Yes and no?" ”

Although the reflex arc is a little longer, people who have no mathematical concepts can figure it out, which shows that the talent is good. Ting Fang's eyes crooked with a smile: "My sister is very good at playing chess." ”

Hou Jingrong said modestly: "The game in the boudoir is not worth mentioning. "It is rumored that those who can play chess will calculate people, and those who cannot play chess well will be loyal and honest. Girls have to hide their clumsy skills, so they can't show off their chess skills.

Tingfang felt that it was a pity, there were many math games in ancient China, but the more they came later, the more bad they were. In the 21st century, many people who play chess say that Go has nothing to do with mathematics. Ting Fang was simply speechless, Go has nothing to do with arithmetic, but it is almost the same thinking mode as mathematics, okay? She had never touched Go in her previous life, but in this life, she had to use acting skills comparable to Hollywood stars to not blow up the whole family. However, everyone in the family thinks that Go is a small skill and attaches more importance to calligraphy. Looking up to the sky and sighing, no wonder the old lady's sorrowful beard is almost white, and there is no successor to the Ye family!

Hou Jingrong was about the same loneliness, endured it for a long time, and finally asked, "Can my sister talk about a game?" ”

Tingfang was also bored, so she nodded in agreement. There are not many games in the boudoir, and what can be put on the table is nothing more than piano, chess, calligraphy and painting. Since the female dependents were invited, they were naturally prepared. led Hou Jingrong to the chess table, and the rest of the people followed to watch the excitement.

Hou Jingrong sat down and opened the box, it was a white piece, but it was not an ordinary chess piece, but a crystal clear agate, and he was stunned for a long time. Qingliu and Quanchen were both civil officials, and in fact, their living standards were very different. Qingliu is naturally poorer, and even the living standards of first- and second-grade officials are not high. In addition, most of Qingliu came from ordinary backgrounds, and poor relatives were in groups, and under the patriarchal system, Qingliu could not sit idly by. Over time, even if Bing respects a lot of charcoal, life is tight. The ministers are different, Zhang Juzheng's luxury, and few in the Ming Dynasty can catch up. The Ye family, who is also a minister, can be said to be not far behind. Even in later generations, agate chess pieces were considered extravagant, not to mention the era when there was no artificial agate.

Ting Fang was unconscious, opened the lid of the sunspot, and asked with a smile: "Sister first?" ”

How could Hou Jingrong rob the little girl first, and said busily: "Sister first." ”

Ting Fang was not polite, he didn't know what level Hou Jingrong was, and being ruthless was the best way. Hou Jingrong was just stopped by Ting Fang by drawing a triangle, and he didn't dare to be careless. The two of you come and go, both holding their breath and concentrating. Tingfang has a natural advantage, she has undergone a very systematic and comprehensive thinking training, which is beyond the reach of the ancients; But Hou Jingrong should not be underestimated, she has no distractions, except for necessary trivial matters at home, and practices diligently every day, not like Tingfang is entangled in things. In particular, Ting Fang is self-taught, and at most she plays a few games with Mr. Kang, and has almost no opponents; And Hou Jingrong is taught by his father, Qingliu has no money, playing chess is the most money-saving talent, and the level of the Hou family can be seen.

The two have different chess playing styles, and Tingfang's strong computing ability and intuition make her move extremely fast and vigorous; Hou Jingrong is a typical literati temperament, calm and moderate.

However, Ting Fang's speed caused great pressure on Hou Jingrong, and beads of sweat gradually oozed from his forehead. I can't wait to think more carefully about every step, and I'm afraid of making people laugh. Especially Ting Fang stared at the chessboard, as if everything between heaven and earth had disappeared, and only black and white were connected vertically and horizontally with the nineteen roads. Two quarters of an hour passed, Hou Jingrong began to be impetuous, the fall was not as orderly as the square, Tingfang quietly dug the pit layout, and when Hou Jingrong reacted, he was powerless to return to the sky. Hou Jingrong secretly glanced at Tingfang's face and couldn't help shrinking. From beginning to end, Ting Fang's expression did not fluctuate at all, and that kind of preoccupied aura was especially terrifying to the opponent.

Hou Jingrong raised his head and found that the people around him had dispersed. The two of them went down halfway, and most of them couldn't understand it. Go is not comparable to the side, if you are not proficient in your own family, you don't know how many meanings are on the chessboard, and over time you feel bored, so you simply talk to yourself.

Ting Fang saw that Hou Jingrong was pinching the white son for a long time, there was no impatience on his face, and he was already silently reviewing in his heart, his mind was divided into two, and he got up with himself in his mind.

Hou Jingrong finally put Bai Zi back into the chess bucket and said with a smile: "I lost." ”

Ting Fang came back to her senses and said with a smile: "Sister agrees." ”

Hou Jingrong took a sip of the teacup and asked, "Can you lend me a look at the "Geometric Original" that my sister just mentioned?" ”

Ting Fang said: "That book is good, but it's a pity that it's a good early book, with a lot of unconfirmed places and vague concepts. I've been writing a set of geometry books lately, the first volume is "Plane Geometry" and the second volume is "Solid Geometry". That "Plane Geometry" was born from "Geometry Original", and my sister should wait for me to write it and then read it together. ”

Hou Jingrong was shocked: "You can actually write a book?" ”

Ting Fang smiled: "Otherwise, why would His Royal Highness King Fu look at me differently?" My sister is not such a layman, but I am afraid that I have never believed the words of fools. To tell the truth, now that I am counted as the court and the people, there may not be a few people who can compete with me in arithmetic. Not only did His Royal Highness King Fu find it interesting, but even the Holy Lord personally told me to take it to him after I finished writing. ”

Hou Jingrong: "......"

blocked people and couldn't say anything, Ting Fang had no choice but to smile.

Hou Jingrong only felt that he had not been stunned for as much time as he had today, and after staying for a long time, he asked quietly: "Sister, have you ever thought about the future?" ”
