I read a book called The Wonderful Kingdom of Counting in the winter vacation. I got a lot of mathematical knowledge from it, including fractions, right angles, triangles and decimal points ... The stories in it are all lively and interesting, but my favorite is the "bluff" in the New Biography of Pig and Eight Rings. Let me tell you something about it.

The Tang Priest and his disciples were walking forward when Wukong found a demon fog hanging over his head. Bajie volunteered to explore the truth. After a while, Bajie came back and told the master that the male demon in front had green face and fangs, and the banshee had long hair. Wukong asked, "How many?" "There are a hundred," Pig said. Wukong asked, "What are they doing?" Pig said, "Make a circle", but a male demon said, "I think the male demon is half of the female demon." A banshee added, "I think there are as many banshees as men." I didn't hear the rest. Wukong listened to Chao Bajie's bullshit. It was a stick. Pig asked, "Why did you hit me?" Wukong asked, "How many goblins are there?" Pig said, "There are fifty or sixty, no, there are twenty or thirty." Brother Sha said, "Second brother, you have gone too far. From one hundred to twenty or thirty, how many goblins are there? " Brother Monkey said, "I think there are seven goblins, only three fairies and four females. A male demon stood up, and the remaining male demon was only half a banshee. So he said banshee is half banshee. And a banshee stood up, and the remaining banshees happened to be the same as the banshees, so she said that there were as many banshees as the banshees. Finally, Wukong asked Bajie to deal with the four banshees, let him deal with the male demon, and let Brother Sha stay and protect the master. " Pig whispered, "The four banshees are difficult to deal with, so you let me go."

This book is very interesting and quite different from other books. The difference is that I have a rich imagination, and I have compiled a lively and interesting story from boring mathematics knowledge, which attracted me to read it at one breath. Meanwhile, every story

It is all a math problem, waiting for me to solve the answer and improve my thinking ability.

Reflections on the wonderful digital kingdom

The Wonderful Kingdom of Numbers is a mathematical fairy tale book, which is a gift from Professor Li Yupei, a famous popular science writer and mathematician, to our children.

There are ten short stories in this book, such as the magical number kingdom, the new biography of Pig and Eight Rings, mysterious numbers, the big fairy with a long nose and so on. However, what impressed me the most, and what I like best, was Eagle Hitting the Sky.

Here's the story. Alpha Kitty Hawk grew up, left her parents and flew into the blue sky alone. She is very happy. However, the wild goose told him that if he wants to be a real eagle, he should not only have the ability to fight the sky, but also know mathematics and know how to do it. Alpha seems to understand. Just then, the vulture said that he would help Alpha, but it ate all the food that Alpha caught for three days in a row. Hungry and dizzy, Alpha was saved by the kind white swan, who severely taught the vulture and taught Alpha math. Since then, the enthusiastic Alpha has used his mathematical knowledge to help Mother Seagull defeat the bandit warship bird, get to know Shrike, and with the help of Brown pheasant, fight the vulture again. With his courage and wisdom, he defeated the vulture and became a real eagle.

After reading this story, I feel that mathematics is everywhere in my life. I must learn math well and be persistent and tenacious like an eagle. ......

Reflections on the wonderful kingdom of mathematics

This summer vacation, I read a fairy tale book about mathematics, The Wonderful Kingdom of Numbers written by Professor Li Yupei. He has a unique originality. He taught us boring mathematics knowledge in the form of fairy tales.

This book is divided into ten novels, the longest of which is The Wonderful Kingdom of Numbers. Its protagonists are brother Xiao Qiang, brother Xiaohua, King 0, Commander 1, Commander 2, etc. Let's talk about the characters first! Citizens of the integer kingdom are both civilians and soldiers; The citizens of the kingdom of fractions are incredible; Citizens of the decimal kingdom are brave and fearless. After a big earthquake, with the help of Xiao Qiang, everyone was unscathed. In short, the citizens of several kingdoms are really capable!

The most impressive story is the mystery on the tortoise shell. It is said that when the crane prince rests on the water, his body becomes a "2" shape. After being seen by the little commander 2, he thought the crane prince had offended him, so he used magic to turn him into an ugly turtle. In order to help the crane prince, kind Xiaohua racked her brains and thought hard, but tried her best to break the spell. Xiaohua met the little mole because of the 45 stones. According to the little mole's answer: =2,

= 4, = 6, = 8,0 =1,= 3, = 5, = 7, = 9. Xiaohua suddenly understood! Originally, you should add these numbers vertically and horizontally, and then you get the sum of 15! So Prince Crane was saved. However, Xiaohua was captured by even soldiers. How touching Xiaohua's spirit of sacrificing himself to save others is!

This book is very funny and very different from other characters. The difference is that this book is full of imagination, and the boring mathematics knowledge is compiled into a vivid and interesting story, which attracts me to read it in one breath. At the same time, every story is a math problem, waiting for me to solve the answer, which improves my thinking potential.

Reflections on the wonderful digital kingdom

Counting and kingdom? There is definitely no such thing in real life. But there is an interesting book that can take us into the kingdom of numbers and feel the fun of mathematics. Dear friends, please join me in this wonderful digital kingdom written by Professor Li Yupei, a famous popular science writer in China.

There are two protagonists in the book, one is Xiaohua, a fifth-grade classmate, and the other is Xiao Qiang, a junior high school student. Both of them are good at math and have won several prizes in math competitions. The two have also done a lot of good things in the digital kingdom and are deeply loved by the zero kingdom. In this book, my favorite story is the part where Xiao Qiang and Xiaohua help Zero King find the treasure. With their intelligence, they caught one treasure thief after another, which made Zero Kingdom very happy. Among them, the part of catching the thief is the most fascinating. So, what is the number of knife thieves?

One night, the number 4 stood guard at the door, and a masked number hooked him with a multiplication hook. Suddenly losing consciousness, the masked number hurried upstairs and met again.

The numbers 12 and 12 just tried to resist, but they were hooked by masked numbers with subtraction hooks and fainted. Coincidentally, the doorman on the second floor happened to have an acute illness on the 40th day, and the knife thief took the opportunity to pretend to be 40 and stole the treasure knife. When the king realized this, he flew into a rage and asked Xiao Qiang and Xiaohua to help the kingdom catch the thief as soon as possible. After careful analysis, Xiao Qiang found the clue: the knife thief hooked 4 with multiplication hook first, and then hooked 12 with subtraction hook, and quickly listed the formula:

4× knife thief 12=40

4× knife thief =40+ 12

4× Knife thief =52

Knife thief =52÷4

Knife thief = 13

It turns out that the number 13 is a thief with a knife. Xiao Qiang used his intelligence to help several kingdoms find the lost treasure knife. I admire him the most.

After reading this funny math fairy tale, I am deeply touched. Looking back at me in real life, I am much worse than the protagonist Xiao Qiang in the book. Often make mistakes and make jokes because of carelessness. Every time I come across some ideas. Now that I think about it, in fact, some problems seem complicated, but they are actually very simple. As long as you are willing to write more, study hard and be careful, you can totally overcome it. If King Zero had asked me to help find the thief with a knife, I'm afraid the thief would have escaped long ago.

It is never too late to mend. In a few months, I'm going to fight in junior high school. Of course, there are many math scores. If I don't study well, I'm sure I won't get into a good junior high school. I envy watching the small bloggers of school ICT get into their favorite schools one by one. I also want to seize the opportunity to study math well and realize my wish.

At first, I thought that boring math had become so interesting that I was attracted to watch it. It also aroused my interest in learning mathematics. After listening to my introduction, do you also want to have a quick look? Friends, let's walk into the wonderful kingdom of numbers and feel the fun and wisdom!
