The so-called people have no long-term worries, of course Tingfang thought about the future, so she was pretending to be a grandson in front of her, and she was pretending to be very good. But God has to let her wear it, she can't even pretend to be a grandson, so it can be seen that she has an egg to think so far. After many things, I have to admit that under the general trend, it is difficult for people not to be coerced, and it is more reliable to see the moves. It's just that this is not good to say to the living, one doesn't know what it will become, and the other party may not be able to understand, and if you have to defend it, you may have to fight, which is meaningless. So he pretended to be naïve, stared at Hou Jingrong with big eyes, but didn't answer.

Hou Jingrong smiled, feeling that he was quite bored. It's rare to meet an opponent in the boudoir, so he revealed Fang Cai's words, and asked: "Another game?" ”

Ting Fang was about to fall, when two little girls ran panting in the distance. Yan Chunfang stood in front of him and saluted Hou Jingrong first: "Sister Hou is good." After Hou Jingrong returned the salute, Fang said excitedly to Tingfang: "That...... That one...... Orbit? How did you get it? I've tried many times with my seventh sister, and the one that bends is faster than the straight one! ”

Ting Fang thought about it, and then understood what Yan Chunfang was talking about, and couldn't help laughing: "Naturally, the rail carriage is fun, isn't it?" ”

Yan Chunfang nodded violently: "It's more fun than the last time, I didn't find that the curve is faster than the straight last time, and the color is not so much, it's so beautiful with colored paint!" ”

Hou Jingrongqi said: "What curve and straight?" ”

Ting Wu danced happily: "It's a slope, and the pony cart can go down the slope." My sister asked the carpenter to make a curved slope on the side of the slope, which was shaped like a crescent moon and ran faster than the slope! Second Sister Yan and I couldn't figure it out, so we came to ask Fourth Sister. ”

Hou Jingrong clapped his hands and smiled: "Then I'm going to take a look." ”

Tingwu was very enthusiastic: "It's in our Xiaoba's house, now Xiaoba is still young, living with his mother, his house is empty, and my sister has put a lot of toys." ”

Hou Jingrong thought it was interesting, he pulled Tingwu with one hand, Yan Chunfang with the other, and called Tingfang again: "You don't look like a child, I won't pull you." ”

Ting Fang smiled and said, "I'll just pull Second Sister Yan." ”

The little girls pulled one by one and walked towards the east courtyard. Ting Yao and the others had seen it a long time ago, but because they hadn't played it yet, they didn't find the mystery in it, so they were curious to keep up for a while. Girls like to find companions, and they can't wait to be accompanied by someone when they go to the toilet. There is no reason not to join in the fun. The banquet of the ladies was held in the east courtyard, and some of the elders had already entered the table, and a dozen or so girls walked in together, which did not attract much attention, and the orders were only for the children to prepare for the table.

Tingwu led the way, and after a short time, he walked to Xiaoba's house. The doors and windows were wide open, and when I stood outside and looked inside, I saw that the three rooms were open, and the floor frame was higher than the floor beam, connecting the three rooms into one. The floor is covered with a thick velvet blanket, which feels soft when you look at it. The most eye-catching feature of the whole room is a colorful wooden railroad carriage in the middle. All the women didn't recognize it, and Tingwu and Yan Chunfang were already familiar with kicking off their shoes and crawling into the house to show everyone.

Ting Wu and Yan Chunfang took a small carriage and put it on the top of one of the tracks, and then said to Ting Fang: "Fourth sister, you shout to start!" ”

Ting Fang raised a hand very cooperatively: "Three, two, one, let's go!" At the same time, his right hand swung down vigorously, like a field commander.

The two pony carriages rushed down the tracks, and sure enough, they were faster in the arc. Hou Jingrong was dumbfounded: "Why?" Shouldn't it be straighter and faster? ”

How can Ting Fang explain the cycloid problem clearly? It also involves the fundamentals of physics. If Newton had been in the parallel world, he would have just defined the concept of differentiation, right? Touching the chin, is Newton still alive? It would be nice to have a chance to meet each other. I can still listen to a few words of English, although it seems that ancient English is difficult. As soon as my mind moved, I thought about going to tease King Fu, not to mention anything else, I could get a few sets of Newton's writings back! Well, Newton was in French at that time, right? Or Latin? But the English version must be there!

Yan Chunfang and Ting Wu were still chattering and asking, "Are all the curves faster than the straights?" ”

Ting Fang smiled: "How is it possible! "It's also a loss, the carpenter is afraid of the power of Ye Fu, and she insists on doing exactly what she does according to her one-to-one drawing, otherwise she doesn't dare to guarantee the effect. That's it, and it was reworked several times. The carpenter who provoked him said that he would never work for her again. But she is not uncommon, after the old lady's birthday, she invited Wei Qiang to play a whole set of playgrounds, and blinded his dog eyes.

Ting Wu climbed down from the house, grabbed Ting Fang's sleeve and asked, "Then why bend like that, you can be fast?" ”

Ting Fang asked, "Why is the self-striking bell so accurate?" ”

Ting Wu shook his head: "I don't know." ”

Ting Fang said with a smile: "A principle, when you can calculate household accounts, and then learn to calculate taxes, and know what geometry is, I will slowly teach you." "Just kidding, calculus is something that can abuse some liberal arts college dogs in later generations, and she can't teach elementary school students even if she is a god. But Tingwu is happy, the first grade of primary school is just the age when you can learn mathematics, hmm...... Copycat logic dog tutorials have to be weighted with math. If you have a good foundation in mathematics, you will have the right way of thinking, and you will be able to use it in the future entrance examinations. I have to give Little Eight Fingers a clear way. She hadn't taught a child, so she had to ask Tingwu to be an experiment. Just like in clinical medicine, there are always so many people who want to be guinea pigs. Fortunately, Tingwu math is a scumbag, and she was adjusted. After teaching for more than ten years, I can always be higher than average.

Yang Yihe had already been attracted to attention, and he also took off his shoes and ran to the toy, picked up a small carriage, put it at the highest point, and then let go, the carriage went all the way down the track, and rushed to the ground in several large circles. She picked it up again and put it into another passage, this time using gravitational acceleration, and after the carriage rushed down, it rushed up a little more in an arc, and then down, and then up, and it flew through several irregular waves before stopping at the designated place. After trying the straights and corners again, and playing all the tracks, I screamed excitedly: "It's fun!" Come on, sisters! Before he could finish speaking, he suddenly saw a strange rope. At the end of the rope was tied a red wooden pull ring, and he reached out and pulled it, but he didn't move, and then he pulled it hard, and suddenly the Ferris wheel at the highest point in the center of the track toy spun rapidly. Yang Yihe covered his mouth with his hands this time, his eyes widened, and he couldn't say a word! Excellent! It's fun! Can you stay at the Ye family tonight and not go back?

Xu Jiqiu screamed: "Ahhhh He will move on his own!!! ”

As a mother, it has been a long-term habit to look after her child. A group of little girls play together, and mothers or grandmothers don't usually theorize, but when there is movement among the children, some of them run up to them and ask, "What's wrong?" What's wrong? ”

Yang Anqin is a childish, she secretly played with people behind her back a few times yesterday, and when she heard Xu Jiqiu's scream, she knew that she saw the waterwheel-like thing in the middle. Hurriedly came to the rescue and said: "It's just a mechanism, what kind of demon magic is it!" Miss Xu didn't believe it, just go inside and take a look. Those organs are all exposed, and the four girls refuse to hide them, saying that the organs themselves are good-looking. I'm dizzy to watch, and all of you children go in to see the excitement. It's all clean inside, and you don't take off your shoes. ”

Everyone breathed a sigh of relief, but they couldn't help but focus their eyes on Ting Fang. Tingfang is going to be famous, people are afraid of being famous, pigs are afraid of being strong, but the pig is strong and breaks the record, people are reluctant to kill, and those with a bad conscience take a cage and put it up for people to watch and make profits, and if the conscience is good, they will stand in the pig's perspective and think of some welfare for it. Visually, whether it is the saint or the prince, he is not a particularly mean person. Heng Zhi is an ancient woman who is called to sell, the strong point is good, and the strong point is valuable! So in the inquiring eyes of everyone, Ting Fang smiled very poorly: "The small skill of carving insects is not enough to hang on to the ears." ”

Everyone: "......" is too modest to show off, okay!

Tingfang beckoned quietly, and An'er, the girl in the iron tower, walked over in a daze, Tingfang: "......" I actually recruited Ping'er......

An'er also asked, "What do you have the girl's command?" ”

An'er is too tall and strong, and today the main family is happy. The black face is smeared with a lot of fat powder, and the body is even more festive, how awkward it looks! It's like a man dressed as a woman. All eyes moved to her again.

Ting Fang had no choice but to say, "You bring the two sets of geometry books in the wooden box on the desk in my room." "That's it, the book is heavy, and it's more appropriate for Sister King Kong to carry it.

An'er rushed to Tingfang's house with a gust of wind, and came out with a set of books in one hand in an instant. Everyone visually measured the size of the wooden box, estimated the weight of the book inside, and a sentence flashed in their hearts - young man! Good skills!

Ting Fang remembered that her five-short figure was not able to drag the book beautifully. So he immediately changed his policy, walked to the old lady with An'er, smiled, and knelt down: "Old lady, my granddaughter is not good at being a girl, so she wrote two sets of books to celebrate your birthday." May you be blessed like the East China Sea and your wisdom will last forever! ”

The old lady twitched the corners of her mouth, the dead girl, the words of birthday celebrations are so flamboyant, and the wisdom lasts forever...... Is it to describe ordinary people? He still had to smile on his face: "I'll take a look." ”

An'er put the two boxes of books on the coffee table next to the old lady. The old lady opened the cover of the box, revealing the seal script "Plane Geometry". Old lady: "......" is recognized by each word when it is taken apart, and it is completely incomprehensible when put together!

The Duchess of Zhenguo probed to see, but she couldn't understand it. Pick it up and flip through it in your hand, and there are ghost drawings in it. But there is no mouth to praise: "Good words!" ”

This time it was Tingfang's turn to twitch the corners of her mouth, and her words were naturally commendable with the phrase "nine-year-old girl", but when she put it outside, she couldn't rank it anyway, and she still had to practice a little more, what a ghost!

Mrs. Kang, who came to accompany her, took a copy and looked at it, smiling silently. The writing is in a hurry, and the Duchess of Zhenguo is afraid that there are few readers.

Xu Jiqiu was frightened, and the Duchess of Dingguo was a little unbearable. complained that her daughter couldn't hold her breath, and when she saw Tingfang in the limelight, she asked, "What is written?" ”

Tingfang replied: "It's a number of books." ”

Duchess Dingguo nodded and smiled: "I only learned today that Mrs. Pan likes to count books, but she gave the wrong gift, and please don't blame Mrs. ”

The old lady smiled and said: "I, I don't like that Rausch, I love beautiful things the most, especially you who are more delicate than flowers, you are happy when you look at it, and you are more than ten years younger immediately!" ”

Everyone laughed and said that they didn't dare to do it.

There is only one person: "Mrs. Pan is modest, if you don't like to count books, why did His Royal Highness King Fu and your granddaughter send this book?" Don't you coax us! ”
