Before Li Chunfeng could speak, Li Er smiled and said, "Dabao, Lao Cheng and Wei Chigong are a little reckless, but they are not stupid, how could they collide together!" The peddler glanced at Li Er and looked directly at Li Chunfeng, Li Chunfeng raised his head with difficulty, "Can Niu Xianchang explain what is a second and what is a meter?" “

Dizzy, forget about the problem of this unit, "Forget it, I'll change it for you that you can understand, let's say that the circumference of Chang'an City is eighty miles, Lao Cheng rides a horse for a quarter of an hour and thirty miles, and Wei Chi plants forty miles for a moment, and the two of them start from the Vermilion Bird Gate at the same time to run around the city, so how long will Wei Chi catch up with Lao Cheng?" “

This is also the mathematics of modern primary school students, and the average person's mental arithmetic is calculated out, and sure enough, Li Chunfeng just pinched his fingers a few times and broke it for the hawker, it seems that there are two brushes, although it proves that you are a talent, then it also proves that we are stupid, we have to think of a difficult point, the hawker scratches his head hard, this will regret that he didn't listen well to the math class at that time, and there is nothing in his stomach!

After thinking about it for a long time, I really couldn't think of any good questions, so I just played the scoundrel directly, "Xiao Li, listen 153994421 add 185217479 and then subtract the 1544223358 and then divide by 325887441 equally?" After the hawker finished speaking, not only Li Chunfeng was flustered, but even the people who were watching the excitement on the side were also flustered, what the is this, it's completely irregular, a few people who want to learn quickly find a stick to write and draw on the ground, the hawker looked at these people and stumped these people, and he was proud in his heart, and drank leisurely with a coke, "Hmph, I don't believe it's hard to stop you!" “

Half an hour passed, and the equation that Li Chunfeng drew on the ground was nearly ten meters long, and he wiped his sweat with his sleeve, and finally threw the stick and ran in front of the vendor, "Immortal Chief, this can't be calculated at all, okay, I'm sure no one in the world can calculate it in one day, Immortal Chief, don't make fun of us!" “

You can't figure it out if you want it, "Hehe, are you sure no one can figure it out?" Then let's do this immortal don't bully you, give you a chance, this time you follow the kind of question I just said, just say the number, I'll count it for you, for fear that you don't believe me, go get a paper and write it down, take this opportunity to think about the number first! “

After saying that, the hawker ran to the car and took his bookkeeping notebook and pen, including the vendor's essential artifact calculator, this thing is only twenty or thirty yuan, pronounced by a real person, hehe, today I made up my mind to have fun with this group of people!

After the hawker came back, Li Chunfeng discussed with a few people who were stealing the school just now, "Niu Xianchang is ready, I'll start reporting the number."

"Tell me!" The peddler spread out the paper, took the pen, and prepared to write down the number that Li Chunfeng said.

"Okay, what is the result of 15235448 dividing by 325441 and adding 24453589896 and then multiplying 416871233 and subtracting 1474552?"

Li Chunfeng and the others looked at the hawker triumphantly after reporting the number, and the hawker wrote the number they said in a capital book, "Come and see what I wrote, right?" A few people took the book and took a look, some of the numbers were not recognized, and after the hawker explained it, Li Chunfeng checked it, "Yes, word for word, then the fairy chief will start counting!" I'll wait for the fairy chief to have dinner together."

Looking at a few people, the hawker slowly lit a cigarette, took a puff comfortably, and then elegantly took out the calculator "One, five, two, three..."Several people who just wanted to leave looked at the calculator in the hand of the goods with dull eyes, and the vendor gave the result without smoking a cigarette and taking two puffs of the calculator, and then took a pen and transcribed it to the notebook and handed it to Li Chunfeng to see!

Li Chunfeng took it tremblingly, and casually glanced at it, "Immortal Chang is ashamed of me and waited, since Immortal Chang has such a divine thing, what do you want me to wait for, tomorrow Chunfeng will return to the deep mountains, and never ask about the world!" ”

I went, overplayed and seemed to "Don't, I'm just joking, no matter how good the fetish is, it needs to be operated by someone, I'm just covered in iron and can hit a few nails, I hope Chunfeng don't worry about it, come to this thing for you, as a meeting gift, I hope you and Lao Yuan will support each other in the future, and make greater contributions to the prince and Datang!" ”

Li Er also helped on the side, "Chunfeng, since the immortal chief has said so, you don't have to refuse, follow Dabao to learn more in the future, I hope you can achieve positive results in arithmetic, and seek well-being for the people of my Datang!" ”

Li Chunfeng saw that Li Erdu had spoken, and it was not good to excuse himself anymore, "Then thank you Niu Xianchang, I will go and prepare to worship the immortal as a teacher!" “

"Stop, don't worship me, so let's go, you go and worship Lao Yuan as a teacher, I'm busy and don't have much time to teach you anything, I'll buy some books for you and Lao Yuan in the future, just learn from each other!"

"Then follow the teachings of my uncle!"

Li Er saw that the hawker had done it, and Li Chunfeng came over: "Congratulations Dabao, let's have a banquet in the front garden!" After that, he pulled the vendor and took the group of bicyclers to drink! It's another night of singing and dancing!

The hawker got up the next day and took the old Yuan and the newly harvested Li Chunfeng back to the broken Taoist temple, Zhu Laoba they were already happy to tie the steel bar there, it seems that the ground beam can be played well, Li Chunfeng saw the strange and didn't care about the dirty directly ran over to help play, the hawker looked leisurely, and then instructed them to tie the steel bar at the four corners of the ground beam, don't rush to grout first, build the wall and then on the plywood grout, the window and the ground beam are the same as a certain height on the direct grouting! A few people wrote it down and went to work, and when I saw that there was nothing wrong with me, I was ready to withdraw!

Lao Yuan hurriedly grabbed the hawker and explained that he had brought a few arithmetic books, because he didn't know what to teach Li Chunfeng, so he asked the hawker to help choose a little, preferably a step-by-step book, and after remembering it, the hawker flashed!

Back to modern times, the town is still like that, but also what changes can be seen every day, remember Lao Yuan's explanation I drove to Xinhua Bookstore, the door of the bookstore is still very clean, but there is no longer the same kind of shoulder to shoulder situation before, only a few children hide under the bookshelf to read comics, the hawker walks in and looks for it, most of them are some celebrity biographies or something, in addition to seeing many physical books of Internet gods, these cow forks that write novels, I heard that there is an annual salary of one million to write novels, this number was unimaginable before, I don't know how these people cultivate, do you think that if we write a novel, will anyone read it?

After giving himself a negative in his heart, the hawker dispelled this idea, we have now moved away from the junior trader of the hawker and turned to the high-level of the inverted master, there is no need to work hard to write novels, but we have the money to buy two books occasionally to support the author.

The vendor turned around and didn't find the ideal textbook in his mind, so he had no choice but to ask the clerk, but he didn't expect her to take a textbook to him on the shelf next to him, "Just look at this, this book is to follow the textbook, not only there are examples in the book, but also many new examples and mathematical solutions, which can well cultivate your child's interest in mathematics, right how many grades does your child go to?" ”

"My child is self-taught, you can get me a copy from the fourth grade to the ninth grade, as long as there are five sets of math!" The hawker counted the number of people with his fingers, the two girls are going crazy every day, Lao Yuan didn't plan to let them really be Taoist priests, and thought about finding their family to send them back one day, after all, whoever lost a chicken and duck or something was distressed, not to mention the two twin daughters, so Lao Yuan occasionally pointed out that they could read Braille, but they didn't teach anything, just buy them some books, learn some math, don't you see that most of the current accountants are girls, and after learning mathematics, they get married or the housekeeper is not, so the hawker ordered a few more sets!

PS: Give me a support.,Collect it.,It's on the new book list this week.,Help me out!
