Reflections on the wonderful digital kingdom

After reading the wonderful kingdom of numbers, I feel 1. The wonderful kingdom of numbers is beautiful, and there are many short stories in it. Mathematics is indispensable in every story, otherwise how can the title of this book be called "The Wonderful Kingdom of Numbers"?

There are many stories dotted in the night sky like stars. One of them is the cleverest, the cutest and my favorite. This is an adventure story about Xiao Qiang and Xiaohua in the digital kingdom.

One summer vacation, Obana's brother Xiao Qiang came to the digital kingdom. When Xiao Qiang helped Zero King find the tenth kingdom, Xiaohua met an ugly tortoise, which was actually a crane prince. County Commander 2 is too narrow-minded. When the crane prince is resting, his body is placed in a shape of 2. The commander forced him to change his posture. Of course, the crane prince doesn't want to. The more they talked, the more stiff they became. Later, the commander turned the crane prince into an ugly turtle. Sealed him with a slot. Finally, Xiaohua helped Prince Crane break the spell.

This book is very interesting and the characters are very vivid. It also taught me new mathematical knowledge, such as irrational numbers and rational numbers, fractional division and so on. I recommend everyone to see it!

Reflections on the Wonderful Digital Kingdom 2 The author of this book is Li Yupei, a famous popular science writer. This book is one of a series of books, a set of 22 books! This book contains ten stories: the magical kingdom of numbers, the new biography of Pig and Eight Rings, the big fairy with a long nose, the judge bear and the detective monkey, sleepwalking in the kingdom of zero, the battle between rational numbers and irrational numbers, the kingdom where decimal points yell at integers, the stories of 7 and 8 and the eagle hitting the sky.

The story in this book is vivid and vivid, which makes me forget all about eating and sleeping. After reading this book, I am more interested in math, like reading Li Yupei's math stories, and want math story books.

Do you want this book? If you want it, buy one!

Not long ago, my mother bought me four must-read books, one of which was called Wonderful Digital Kingdom, which deeply touched me.

This book is mainly about the kingdom of integers and the fierce struggle between men and women. Fortunately, thanks to Xiao Qiang Xiaohua's witty defense, the two factions of Integer Kingdom avoided fighting. In the integer kingdom, they also encountered many problems, but it was also a whirlwind treatment; They also encountered many great difficulties, such as the attack of bison, and invited three brothers of the triangle family to subdue bison; When the eagle tried to play tricks on the integer people, it found lions, tigers and monkeys to drive away the invaders. ...

The second thing that attracted me to watch was Sleepwalking in the Zero Kingdom: A child came to a palace in his dream, and a girl came out to meet him, introducing herself as Wang Xiaoling, and wanted to show him around her Zero Kingdom. The citizens here shave their heads. You can shake hands with them safely, but you can't hug them. Shaking hands is like a plus sign, you are still yourself, hugging is like multiplication, and you will become a citizen of the kingdom of zero. ...

This shows how mysterious mathematics is and an indispensable part of life.

Reflections on the Wonderful Digital Kingdom 4 This summer vacation, I am reading the book Wonderful Digital Kingdom. Looking at it, I found a very interesting article-pig and eight quit fighting crocodile essence. Even my mother thinks I look like the eight rings in the story. Here's the story.

One day, Pig Bajie volunteered to explore the road. When he crossed the river, he was dragged back to his nest by a crocodile. Pig Bajie asked crocodile essence to test him in order to prove that he was not stupid. Crocodile essence said: "I am a long-tailed crocodile." My tail is three times as long as my head, and my body is only half as long as my head. My tail and body add up13.5m. How long is my head? " Pig Bajie secretly complained, but he still counted it: "I divided you into several equal parts, the head is 1, the tail is three times that of the head, and the tail is three, so the body can only account for three-thirds, so the total length is 1 1/2." Well, that can be solved. Just then, Bajie reported a formula: "Crocodile head length =13.5 *1/2 = 27/11(m)". Just after that, Bajie heard Wukong's voice: "Bajie, the calculation is wrong. 13.5m is only the length of its body and tail, excluding the length of its head, which should be 13.5*(3/2+3)=3 (m) ". At this time, the crocodile essence said, "My head is 3 meters. You have miscalculated!" " "He came to eat Bajie, and Wukong suddenly appeared and saved Bajie!

Pig Bajie is so careless that such a simple question can be miscalculated. Fortunately, Wukong saved him, otherwise it would be the dinner of crocodile essence. In fact, I am also a careless person, and I often make mistakes in calculation. If I copy numbers, I will make mistakes, so my correct rate will be reduced and I will not get good grades. I must correct this "problem" in the future and make my grades better!

Reflections on the wonderful digital kingdom 5 During the holiday, my mother bought me a meaningful and interesting book: Wonderful Digital Kingdom.

There are several math fairy tales in this book! There are 10 stories about school children, such as the wonderful digital kingdom, the new biography of Pig and Eight Rings, and the fairy with a long nose. What impressed me the most was the fourth story in Zhu Bajie's new biography: the bag on his forehead.

The story is mainly like this: the master and the apprentice were too tired to walk, and the Tang Priest told everyone to rest in place. At this time, Sun Kong found many pebbles. He asked Bach to play a little game of 15. The rule is that whoever can get enough pebbles wins, and the loser is knocked on the forehead by the winner. The first game they played began. I forgot to tell you, Wukong divided these stones into 1 as a pile, 2 as a pile ... 9 piles for a * * *. It's not easy, thought the pig. Nine plus six equals fifteen. So Bajie took a bunch of nines first, and Wukong quickly took a bunch of sixes; Pig cursed in his heart, and the monkey head () was so cunning that it ruined my plan. He had no choice but to take a bunch of fives. When he wanted to take the pile of 1 again, Wukong reached out and took it away. They played several times, but Bajie still lost. As a result, Bajie had several bags on his forehead. He touched the edge of his forehead and thought, "Why does that monkey head win every time?"

After reading a story, I was deeply touched. the Monkey King is really smart. He can take Nine palace map, who he saw in Taishang Laojun, and he came up with a little game to rob 15.

After reading this book, I learned a lot of math knowledge. I have read this book for the third time. I can't put this meaningful and interesting book down. Are you interested in watching it? I can lend it to you! How interesting!

Reflections on the Wonderful Digital Kingdom This summer, Mr. Mix recommended a book called Wonderful Digital Kingdom to us. There are many interesting fairy tales in this book, which was written by Li Yupei, a famous popular science writer in China. He is very good at using children's favorite fairy tales to make abstract and boring mathematics knowledge easy to understand and let readers get in touch with mathematics in pleasure. Professor Li Yupei's works are unique and distinctive, and are deeply loved by children all over the country. I learned a lot of math knowledge in the story.

There are 10 stories in it, such as: the magical kingdom of numbers, the biography of the new pig and the big fairy with a long nose … However, the stories of 7 and 8 are my favorite. Story telling: Mom bought Xiao Yi a plastic math treasure chest, which contains ten numbers 0, 1, 2…9, four operation symbols+,-,-and ÷, and an equal sign. Xiaoyi is very happy, dancing and singing while running.

He was so absorbed in dancing up and down with the box that he didn't even know that two numbers had fallen out of the box. Bang, bang, the numbers 7 and 8 fell to the ground, and 7 and 8 shouted: stop, stop, dump us. But Xiao Yi didn't look back and ran away with the song in the distance. 7 and 8 are in a hurry, but they still stand up and look for their digital brothers. On the way, they met a manhole without a cover. They fell into the sewer together and met an old gutter rat. Old gutter rats always want to dig at them, but they are very clever. For example, the old ditch mouse asked for a 0, and 7 hit 8' s waist with its head, and two 0' s came out at once. The old gutter rat wants a 2. Seven was originally a prime number, but later it became three twos. The old sewer rat asked them to form another big number. Number eight is really a little angry. He raised his hand and patted his bald head twice in a row, and poof became three twos, and these three twos and sevens became a huge number.

The two figures are clever and naughty, which makes the old ditch mouse furious. With their intelligence, they have overcome difficulties again and again. I think this is worth learning from. We often don't want to continue thinking when we encounter problems. I will learn from them in the future. The content in it is wonderful, which makes me feel that learning mathematics is no longer a boring thing, but a very interesting knowledge.

Reflections on the Wonderful Digital Kingdom 7 This summer vacation, I am reading the book Wonderful Digital Kingdom. Looking at it, I found a very funny article-pig and eight quit fighting crocodile essence. Even my mother thinks I look like the eight quit in the story. The story goes like this:

One day, Pig Bajie volunteered to explore the road. When he crossed the river, he was dragged back to his nest by a crocodile. Pig Bajie asked crocodile essence to test him in order to prove that he was not stupid. Crocodile essence said: "I am a long-tailed crocodile." My tail is three times as long as my head, and my body is only half as long as my head. My tail and body add up13.5m. How long is my head? " Pig Bajie secretly complained, but he still counted it: "I divided you into several equal parts, the head is 1, the tail is three times that of the head, and the tail is three, so the body can only account for three-thirds, so the total length is 1 1/2." Well, that can be solved. Just then, Bajie reported a formula: "Crocodile head length =13.5 *1/2 = 27/11(m)". Just after that, Bajie heard Wukong's voice: "Bajie, the calculation is wrong. 13.5m is only the length of its body and tail, excluding the length of its head, which should be 13.5*(3/2+3)=3 (m) ". At this time, the crocodile essence said, "My head is 3 meters. You have miscalculated!" " "He came to eat Bajie, and Wukong suddenly appeared and saved Bajie!

Pig Bajie is so careless that such a simple question can be miscalculated. Fortunately, Wukong saved him, otherwise it would be the dinner of crocodile essence. In fact, I am also a careless person, and I often make mistakes in calculation. If I copy numbers, I will make mistakes, so my correct rate will be reduced and I will not get good grades. I must correct this "problem" in the future and make my grades better!

At first, I thought it was just a book about mathematical formulas. After reading it, I found it was a book about mathematical fairy tales. The characters in the book are lifelike and very attractive.

There are ten chapters in this book, and different chapters have different attractions. The protagonist in the book is Xiao Qiang, a fifth-grade pupil. Both of them have rich mathematical knowledge and won many prizes in mathematical competitions. The two have done a lot of good things in the digital kingdom and are deeply loved by Zero King.

In this fairy tale, I know the music score of ancient Egypt, which I have never heard of. In fact, it is what we often call the' fractional unit', which was first mentioned in a book by a man named Amos five thousand years ago. Every ancient Egyptian score is the reciprocal of an integer.

Besides, I know the number of blind dates. 220 and 284 are a blind date. The sum of all true factors of 220 is 284, and the sum of all true factors of 284 is 220. This let me know: you have me, I have you, love each other and never fight.

Once, several kings came from abroad, a man-eating monster. The monster saw 60 and 15 guarding the door, so he ate 60 and threw 15 on the ground. I went to the city and ate 24 and 44, but the monster was still hungry, so King Zero thought: We can send several teams to see what the monster eats, so he sent 100, but the monster ate 100. Will the monster finally eat a zero? But the endings of 24 and 44 are not zero, and they are also eaten. King Zero suddenly realized and jumped into the monster's stomach. Everyone was shocked. It turns out that King Zero already knew. The monster moved a few times and died. King Zero and everyone came out. King Zero turned everyone into zero, and the monster starved to death.

How colorful it is to see the world of mathematics!

After reading The Wonderful Kingdom of Numbers, I have learned a lot about mathematics since I read The Wonderful Kingdom of Numbers.

In this book, we can learn a lot about mathematics through fairy tales and interesting explanations. After reading a story, I will know a little math. When I do this problem, I know how to do it. When I read the whole book, I will learn a lot about mathematics, such as: in the alphabet, the letter "A", in mathematics. Multiply zero by any number other than zero to get zero. ...

In this book, let me understand a truth, mathematics is not that difficult. If you study hard, you will find that math problems are not difficult at all, and they are very interesting.

Is there a kingdom of 10 after reading The Wonderful Kingdom of Numbers? 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. 4 suddenly lost consciousness, the masked number hurried upstairs and met 12 and 12. Just when he tried to resist, he was hooked by a masked number with a subtraction hook 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 knew this, he flew into a rage and asked Xiao Qiang and Xiaohua to help several kingdoms 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 interesting 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. Whenever I encounter some difficult problems, I will deliberately avoid these complicated problems and be too lazy to think. 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.

The book "Wonderful Digital Kingdom" has given me great inspiration, benefited me a lot, and made me have a deeper understanding of mathematics. It turned out that I found boring mathematics so interesting that it attracted me to read 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!
