Section 78 Binary quadratic
The peddler thought about it, if the old cat can really get it out, he can really ask for it, but not now, now he doesn't even have a place to live in the Tang Dynasty, he has to wait for Li Er to ascend the throne, and he tries to ask him for a piece of land by the river, it is estimated that it can be "That is a must, how can my brother be joking, I can't get a pump by myself if there is no river!" ”
"There's a pump, you want a water pump!" The old cat was already sure that the vendor was coughing with him!
The peddler was speechless, if it weren't for the fact that the Tang Dynasty didn't popularize electricity, it wouldn't have been popularized! It's not at all except for the last time I used it for an activity, but I can't show my timidity, and the old cat is also a choice, isn't it "I like water power, you wait for my news, and I'll tell the person in charge of the museum after a while.,Maybe people will get it as soon as they're happy.,After all, there's a fund to get!" ”
"Hehe, I understand, that brother is waiting for your good news!" For the hawker's nonsense old cat can only express a certain degree of limited trust, how to say that sentence "people, there must be some ideals, what if it is realized!" "Of course, I hope that the same is true, otherwise so many people know that they can't win the prize, and they still desperately buy lottery tickets!
Those who do business are all human spirits, listen to the string song and know the elegance to put it bluntly, it is to pout the ass and know what to pull, the hawker decided not to talk to the old cat, the thing has to buy some cotton, seed cotton and lint each bought two hundred pounds, this thing really occupies space, after the cotton is pulled back, the vendor plugs the disc sent by the old cat into the computer and puts the video out to roughly see how things are played, and he pulled the cotton back and forth on the ginning machine a few times, and the deseeding effect is OK, but it is not as fast as the diesel engine that I saw when I was a child. But it can also be improvised, anyway, the people of the Tang Dynasty are not short of time, unlike modern people who are busy every day and are about to be reincarnated tomorrow!
Now that everything is ready, the vendor decided not to stay here, and after the past, Lao Yuan and Li Chunfeng had a headache holding the math book, and this goods went over and brought the book over, "What's the situation?" ”
"Uncle Shi (Gong), what is a one-dimensional quadratic equation, and what is a binary quadratic equation?"
"Ugh! What kind of peddler is the second element to know.,After all, I've read a lot of comics.,What is the binary quadratic equation is returned to the teacher.,But there's still a little impression.,Break the book.,Randomly found two example problems to solve these two problems.,In the admiring eyes of the two, the hawker was a little fluttering.,I thought about whether I should also learn something.,In case they see high school math in the future, what can it be?
Because the vendor heard a buddy who dropped out of high school in the village say, "When I was in junior high school, mathematics was still composed of numbers, and occasionally some symbols were in the upper right corner of the numbers, and after I went to high school, the math books were full of English symbols, and occasionally there were some numbers, and I ran to the upper right corner of the symbols, you especially teased me!" So his words ruined the high school enthusiasm of a hawker who is not good at math and English! He was afraid that what he would do if he was admitted to college, so in order to cut off this pain, he went home directly with his schoolbag.
After solving the problem of the two people, the hawker put a bunch of cigarettes and alcohol brought to them, and told them that if they ran out of sales, they would tell themselves again, now that many officials and eunuchs in Chang'an have run out of tobacco and alcohol, they all went to this broken Taoist temple to find Lao Yuan to buy, because the hawker has been unstable recently, and he is busy completing Li Yuan's business, should he buy a piece of land and make a shop or something? Hawkers think about it or forget it, if you want to get a shop, you have to go up with cement glass or something, now it is difficult to find a few steel frame workers in Datang, you have to teach yourself first, this will be busy with heels hit the back of the head, or wait for this time to pass!
The hawker drove to Li Shimin's house, it happened that today is estimated to be Sunday, they seem to be called the tenth day of the rest of the day, anyway, I don't know what time it is, Li Er happened to be at home and there was no one else, seeing the hawker coming Li Er came from afar, took the hand of the goods and quietly asked, "Dabao, have you bought the things?" ”
The vendor raised his eyebrows at him, and Li Er immediately smiled, "You do something, I don't worry, go to the backyard to meet your sisters-in-law!" ”
The peddler hurriedly waved his hand, "This is not good!" He remembered that people at this time were the most taboo about this, and this was the future emperor, but Li Er was so energetic that he dragged the vendor to the backyard, and the goods began to struggle, and then he thought that this was also a good opportunity to visit Li Er's house, so he half-pushed and half-followed.
A group of eunuchs in the backyard and Yingying Yanyan's, put a lot of tables of mahjong, the hawker only then knew why there were a lot less tables and benches after the last exhibition, it turned out to be Li Ershun left, it is estimated that other people also took a lot of away from the same, and lost a lot of money to the chef when he went back, Li Er saw the hawker saw these things and smiled at him embarrassedly, "It's all Lao Cheng's start, that day while you were busy, I moved back for you, if Dabao you are still useful, I will let someone send you back!" ”
When the emperor is hypocritical, what else to send when they come to your house" Brother Li is polite, it is also their blessing that these things can go to Brother Li's house, and I hope that Brother Li will not dislike it and use it unaccustomedly! ”
"Hehe, get used to these tables and chairs are much better than my original couches, especially playing this mahjong time, not to mention how comfortable, don't talk about these, I'll introduce you to your sisters-in-law, I won't talk about the eldest grandson, this is Wei's, Yang's, Yan's..." We can't remember the titles you let yourself call them one by one, just call them sister-in-law, it doesn't matter if it's right or not, it's not a scolding anyway!
"Concubines, Da Bao has a gift for you today, guess what Da Bao will bring to you? Guess right, I'll reimburse you for Dabaona's account! Li Er yelled at his woman!
The eldest grandson was the first to speak, "Then you still need to guess, it must be something for a woman's family, right, Dabao?" The peddler gave a thumbs up to the eldest grandson, this person is too good at talking, Li Er also said that since they all said that they were sending things to them, it must be something from the woman's family, and the eldest grandson summarized it at once, although it is not specific, but you can't say that what people say is wrong, right?
"Sister-in-law of the eldest grandson guessed right, a few people will make room for it, and I will pour out the things!" Several palace maids and eunuchs moved the table and bench to the side, all acquaintances knew that this thing was poured out of the panda, and the door was clear! So no one was frightened!
Swish! A lot of things appeared out of thin air in the middle of the clearing, Rao is these people have seen the situation of taking things out of this place, and they were also shocked by the things that the hawker took out this time, only the corner of Li Er's eyes inadvertently twitched, thinking that it was over, with the black heart of the hawker, it is estimated that this time it will be ruined again!
PS: Still four more to ask for collections, ask for tickets! Trouble pity the poor noodles, the book is free, I hope it doesn't get a free ticket!
