A wonderful 400-word composition of the digital kingdom after reading it
The story in "Wonderful Digital Kingdom" is also very nice. This book tells many mathematical principles in the form of storytelling. The following is a wonderful 400-word composition I brought to you. I hope you like it!

Wonderful 400-word composition after reading Kingdom of Numbers (1)

After reading the book The Wonder Kingdom of Numbers, I learned a lot about mathematics. For example, the condition for the formation of a blind date number is that the sum of all true factors of A number is equal to B number, and the sum of all true factors of B number is exactly equal to A number, which is a group of blind date numbers; The score of ancient Egypt includes 2/3, and all molecules are1; 6 is the smallest perfect number; Infinite loop decimal 0. 66767 can be abbreviated to 0. 67; 2= 1

In this book, I think the most interesting is the contest between rational numbers and irrational numbers. In the story, because the irrational number asked to change its name, but the rational number refused, the irrational number fought with the rational number in a rage. With the consent of Commander л and Commander 1, command personnel to duel. Later, after two duels, Commander л withdrew his territory and never invaded again, knowing that he was no match for Commander/kloc-0.

The story in "Wonderful Digital Kingdom" is also very nice. This book tells many mathematical principles in the form of storytelling. For example, the short story "The Battle of Bison Mountain" made me understand that triangles are stable. The story "the Monkey King has a problem" let me know 0. 9= 1; Rebuilding Metric City taught me that width divided by length equals 0. The rectangle of 6 18 is a golden rectangle.

The book The Wonderful Kingdom of Numbers has taught me a lot of math knowledge. I recommend you to read this book.

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 a fractional unit. Five thousand years ago, a man named Amos first mentioned it in a book. 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!

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. 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? four

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. Because of carelessness, I often make mistakes and make jokes. 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!

I read a book "Wonderful Digital Kingdom" the other day. This is a gift from the mathematician Professor Li Shupei to the children. This is an interesting mathematical fairy tale, and the short story in the book is very humorous. There are also some math problems interspersed among them.

The story begins like this. Two fifth-grade pupils accidentally broke into the digital kingdom and found that the two armies were at war, which was quite lively. As soon as I knew the situation, it turned out that odd and even numbers were at war. In the kingdom of numbers, 0 is king. 1 and 2 are the commanders of the odd and even teams respectively. On this day, Commander 1 and Commander 2 were fighting for numbers. There is nothing the king can do. Finally, the wise Xiao Qiang learned from King No.0 that Commander No.2 worshipped Pythagoras, the ancient Greek mathematician. In the words of mathematicians, all the numbers are you and me, me and you-blind date numbers. Quelled the war.

There are several children's favorite stories about the Monkey King and Pig Bajie, which show the Monkey King's cleverness and wit and Pig Bajie's simplicity and loveliness.

I tasted interesting stories and learned a lot of math knowledge. This is really a good book.

Recently, 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. 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: "The head length of crocodile =13.5x1/2 = 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 13.5x(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!
