Mathematics kingdom composition 1 I am a primary school student, and now I am about to enter middle school. One day, I was walking in a dark grove when I suddenly heard a strange bird chirping. I looked up and saw a huge bird flying slowly, as if walking. Because I looked like an X, I became interested and fell into the pit and fainted unconsciously. ...
When I woke up, I saw a bunch of numbers around me. When they saw me awake, they lifted me up and saw my surprised expression. They told me the history of this "alien planet" ... "So this planet is a kingdom of mathematics," I cried in surprise. "Come on, show me around." I followed X to the street, which was full of digital people. I also met a kindergarten kid who overreached himself-6.1596348 and Uncle π has more decimal places than anyone else, which is really cute.
Unconsciously, we came to the mathematics palace, and the king of mathematics greeted me warmly. When I saw him, I couldn't help shivering. Wow, starting with 9, put on your cloak. This cloak is made up of nine numbers, which should be the largest number in the mathematics kingdom!
Sleep in a bed made of hundreds of millions 1 at night. Just after I fell asleep, a "ding" sound woke me up. I sat up, looked at the alarm clock, stayed for a while, and suddenly reacted, "Ah, it's seven forty-five, and I'm going to be late." When I hurried halfway, I suddenly remembered that it was Saturday! Jumped up with joy, turned and hurried home. ...

The cloak is very long and consists of nine pieces connected together. This should be the largest number in mathematics.
Sleep in hundreds of millions of beds at night. I had just fallen asleep when a ding woke me up. I sat up and looked at the alarm clock.

Mathematics kingdom composition 3 big news, big news! Hey, you know what? In fact, many animals in the animal kingdom are "mathematical geniuses".
Honeycomb is a strictly hexagonal cylinder, with a flat hexagonal opening at one end and a closed hexagonal diamond bottom at the other end, which consists of three identical diamonds. The rhombic obtuse angle of the chassis is 109 degrees 28 minutes, and all acute angles are 70 degrees 32 minutes, which is both firm and material-saving. The honeycomb wall thickness is 0.073 mm, and the error is very small.
Red-crowned cranes always migrate in groups, forming a "human" shape. The angle is 1 10 degrees. More accurate calculation also shows that half of the herringbone angle-that is, the angle between each side and the crane group direction is 54 degrees, 44 minutes and 8 seconds! And the angle of diamond crystal is exactly 54 degrees, 44 minutes and 8 seconds! Is it a coincidence or some "tacit understanding" of nature?
The spider's "gossip" net is a complex and beautiful octagonal geometric pattern, and it is difficult for people to draw a symmetrical pattern like a spider's net even with rulers and compasses.
In winter, when a cat sleeps, it always shrinks its body into a sphere, which is also mathematical knowledge, because the sphere makes the cat's body surface area smallest, so it emits the least heat.
The real "mathematical genius" is coral. Coral writes an "old calendar" on its body, and "draws" 365 stripes on its wall every year, which is obviously one stripe a day. Strangely, paleontologists found that corals 350 million years ago "painted" 400 watercolors every year. Astronomers tell us that at that time, there were only 2 1.9 hours in a day on the earth, so a year was not 365 days, but 400 days.
Today is Thursday. After the exam, I turned on the computer to chat about QQ. Just as I was chatting, a striking big word "What's your favorite subject?" Appear on the computer screen. I meditated for a while, then I typed in the word "math" and clicked "Enter". A flash involved me in the computer, and I drifted in the time tunnel. Suddenly, a kingdom appeared in front of me. I looked at the words on the kingdom and couldn't help but stay-it actually said, "Welcome to the kingdom of mathematics! ! "Without further ado, I was inexplicably excited and rushed into the kingdom like an arrow from the left!
Just as I was about to enter the country, the math soldier outside stopped me and said to me, "You must finish these math problems before you can enter the country." After that, I have a ballpoint pen and a piece of paper in my hand. When I looked at it, I couldn't help laughing. These topics are for my third-grade classmates, and even for a fifth-grade classmate. How dare you! Finally finished, math soldiers let me into the kingdom. ...
I searched in the kingdom and stayed in the "Mathematics Inn". There were so many people in it that I managed to occupy a luxurious room first. After entering the room, I was exhausted. I fell on the bed. At this time, I was bounced back to the ground by the bed. I fell on a bed of "dogs are willing to mud" and said, "You must complete the crossing of 10 before you can have a rest!" Well, I have to do this in order to rest. When I do it, there is a button next to the table. When I pressed it, I drifted in the time tunnel and I came home.
Sitting in front of the computer and looking at the screen, there is still a big line on the screen, "What's your favorite subject?" I dare not enter it again, because I don't know what will happen to me. ...
One day, I was looking up the dictionary and typing with relish. Just when I was about to "publish", a gust of wind blew me into the sky. Then, a black hole attracted me to a planet.
I don't know how long it took me to wake up from the green grass. Touching my sleepy eyes, I couldn't help but look at the plaque with the words "Kingdom of Mathematics" written on it. I was stunned first, and then jumped three feet high. As for why, I won't say it. I can't wait to enter the kingdom of mathematics.
However, when I walked into the gate, a 13 and a 16 stopped me. They said to me: Are you from the kingdom of prime numbers? Or someone from the digital kingdom? I smiled and asked, "What are the characteristics of prime numbers and composite numbers?"
13 cleared his throat and said loudly, "A prime number means that there are no other factors except 1 and itself, such as 3, 5 and 7." As soon as the voice stopped, 16 said, "The composite number means that there are other factors besides 1 and itself, such as 4,8, 15." I was puzzled and asked, "Are all the numbers even?" 13 said, "No, you see 2 is an even number, but it is a prime number because it has only two factors: 1 and 2." 16 went on to say, "You see, 9 is a composite number, but it is also an odd number."
"Oh, I see!" I nodded in confusion.
13 said, "Wait a minute, we'll give you some questions to do!" "Write it down on paper when you are finished. I did it successfully. They let me in. I was surprised: "Why did you let me in? 16 said: "In our country, doing the right questions after learning knowledge can satisfy a wish. We see through your thoughts, so we let you in. " "Oh!" I nodded and entered the kingdom of mathematics.
Students, let's find some questions about prime numbers and composite numbers.
Today is a sunny day. Today is the birthday of squirrel pistachio. Early in the morning, all the small animals in the forest came to Pistachio's home to celebrate his birthday.
After celebrating the birthday of pistachio, the small animals put presents on the table. All the animals left except their good friend, the white rabbit. The little white rabbit took out a box from his schoolbag and said to the pistachio, "This is a treasure chest of mathematics. Only when you return to the bedroom can you open it. "
After seeing off the white rabbit, Pistachio quickly returned to the bedroom, gently opened the treasure chest, and a dazzling light shone from the treasure chest, which blinded Pistachio. After a pause, the light gradually dimmed. Pistachio opened his eyes and saw a number 9. The number 9 spoke. Today is your birthday, and I want to take you to roam my world-"the kingdom of mathematics".
Blink of an eye, the number 9 and pistachio came to the kingdom of mathematics. They walked and walked when suddenly a forest appeared in front of them. Pistachio saw a wooden sign that said "Thorn Forest". The thorn tree said, "If you want to go through the forest, you must pass me first." Pistachio agreed with pleasure.
The thorn tree said, "The first bag of biscuits weighs 0.4 kg, the second bag of biscuits weighs 0.40 kg and the third bag of biscuits weighs 0.400 kg. Are these three bags of biscuits the same? " Pistachio thought for a moment and said, "It's easy, of course there are so many." The thorn tree said, "Congratulations, you got it right." You can go there.
Pistachio nuts follow the number 9 and play in the mathematics kingdom all day. I'm so happy!
Math Kingdom Composition 7 "plop" 1, I just got back from the training class, and fell on the bed with my eyes closed, enjoying the coolness of the air conditioner.
In this way, I fell asleep ...
When I open my eyes, two round eyes will pop out. What! Where is this? I saw a sea of people in the street. Neither the seller of steamed stuffed buns nor the seller of baked wheat cakes seem to take my little girl seriously. I rubbed my eyes and got up. A huge sign stands there. "What? A kingdom without mathematics? " I was a little surprised, "Goo goo ..." Oh! Hungry, I quickly put down those doubts and searched my whole body. A lot of change poured out of my pocket and several coins fell to the ground. I quickly reached out and picked them up. I was surprised to find that people's sleeves were long and short. There happened to be a biscuit seller next to me, so I quickly asked, "How much is a biscuit?" The man simply replied, "2 yuan". I paid for it and took a big bite. I want to buy two more. "How much are the two? ""5 yuan "I am very angry, it is 4 yuan! "Why, do you want to charge more? "I stared at him and cried," hey hey, king! She is unreasonable! The peddler smiled and said to the passing king. I ran away like a depressed mouse, but the soldiers sent by the king caught me. I fell silent, so the king asked the soldiers to bring a big board and plop. I just started playing, and I immediately fainted. ...
I opened my eyes and found myself still lying in bed. It was a dream!
This strengthened my determination to learn math well, and also made me understand that we can't live without math, so we should learn math well and make good use of it in our lives!
A few days ago, my classmates and I were swimming in the ocean of mathematics, having fun, and accidentally bumped into a square guy. We quickly said, "I'm sorry, I'm sorry!" "Apologize while bowing. He smiled and said, "Never mind! "I just got up and looked: ah! If it isn't the famous Mr. Rubik's Cube!
He adjusted his suit, shook my hand, and then politely introduced: "My name is Cubic, and this is my brother-Cuboid. Nice to meet you! " We were so happy that we smiled and said, "Nice to meet you, too!"
Cuboid went on to say, "He is my twin brother, so everyone calls him' Special Cuboid'. He looks like me, but there are some differences. I'm telling you, look carefully! I have six faces, 12 sides and eight vertices ... "The cube cheekily inserted:" I am no less than my brother, and I have another feature that can distinguish me from my brother-my six faces are exactly the same!
The cuboid withdrew the topic and continued to introduce it in an orderly way: "I usually call the long side of the bottom surface long, the short side wide and the side perpendicular to the bottom surface high." My brother is called side length because the length, width and height are all equal. "
Seeing that my brother was thirsty, the cube introduced instead of my brother: "The sum of the areas of my brother and me is called the surface area. My surface area is hard to find. First, find the area of a surface and multiply it by 6. You can also write it like this: side length × side length ×6. My brother's solution is more difficult: (length× width+length× height+width× height )× 2, that is, first find the front, left and top, and then multiply by 2, because the relative surface areas are equal. Ok, brother is going home to drink water, goodbye! "
"Ok, goodbye!" We are reluctant to say. I'm glad to know them. They taught me a lot!
Mathematics kingdom composition 9 mathematics, this word makes me feel excited and happy. Every time I hear this word, my face will be filled with a bright smile.
The kingdom of mathematics is a magical and mysterious world, and those numbers, like elves, guide me to success. That series of formulas, let us understand the simple calculation method, teach us, when encountering difficulties, don't be afraid, stay awake, and we will certainly succeed. Every time I see that puzzling math problem, I am extremely excited. The more difficult it is, the more I want to overcome it.
During the exam, I prefer to answer the climbing question at the end of the test paper, because I don't think it's difficult, just a little roundabout. As long as you are calm, you will succeed and gain something. Moreover, I think they are like hateful monsters, challenging me, and I am like a brave man who must defeat those monsters.
Because I love mathematics, I also bought a book on Olympiad Mathematics. As long as I have time, I will discuss the above problems and solve them. I will have some little happiness. If I fail, I will try my best to overcome it. When I succeed, I will think: Haha, I finally solved this problem! I want to challenge more difficult questions. Peng, come on Hold on! Sometimes it takes me a whole morning to solve a problem. I spent a lot of draft books!
I deeply remember what my mother said to me: "You like math, so you shouldn't be lazy, but you should work harder than others." In this way, you will gain more in this subject. I understand the profound meaning of what my mother said to me. So I will redouble my efforts and strive for greater gains.
Math kingdom, I will try my best to challenge more questions hidden in your heart.
Mathematics kingdom composition 10 this semester, negative numbers and positive numbers came to the mathematics kingdom to visit the king of mathematics "0"
Negative numbers and positive numbers come to the kingdom of mathematics. The king of mathematics introduced positive numbers and negative numbers to nine brothers and four partners: "members of the mathematics kingdom, I now introduce two new members, positive numbers and negative numbers." To make it easier to remember, give each of them a symbol. What should I do? "
"Then positive numbers are marked as"+"and negative numbers are marked as"-". Because positive numbers represent profits and negative numbers represent losses. " "x" said.
"OK, then positive numbers are marked as"+"and negative numbers as"-",but"+"is pronounced as positive numbers and"-"as negative numbers." The king of mathematics said, "positive numbers are bigger than negative numbers, so they live on my right." Negative numbers are smaller than positive numbers, so they live on my left. "
"Positive numbers, as long as they are greater than 0, are positive; Negative numbers, as long as they are less than 0, are negative numbers. I am neither positive nor negative. The center of your midline. " The king of mathematics said.
The king of mathematics added, "You have a great role to play. You should do your part for the world! Positive numbers can represent warehousing, transportation, deposit, zero, profit, etc. Negative numbers can represent warehouse, shipment, return, below zero, loss and so on. If you are a friend, it will be of great use. "
Since positive numbers and negative numbers are reconciled, they are good friends and partners in life and antonyms in mathematics.
Food packaging has traces of positive and negative cooperation. For example, 500.50 on the biscuit. Temperature, salary card, passbook and other places have positive and negative numbers.
Now there are two new members in the mathematics kingdom: positive numbers and negative numbers.
Mathematics Kingdom Composition 1 1 One night, 0 and 1 walked together and quarreled. 0 said, "I am the most important and biggest of all numbers." 1 sneered: "How is this possible? I am the most important. I am older than you. " They can't convince anyone. At this time 1 is called multiplication sign to judge, and 0 does not show weakness. He called all his brothers and sisters together. Multiplying the numbers to see the reform, he said, "It's amazing, it's so big! 1 0,100,1000,10000. ",1unconvinced. He waved his baton and ran to ask other friends for help. Multiply it by the symbol. Alas, without 1, all the reforms would be zero, not much. At this moment 1 came back, and 2, 3, 4, 5, 6, 7, 8, 9 stood behind him. They all laughed and said, 0 light eggs also said that they are the most important and the biggest! 0 was very angry and said, "There are too many of you. I want to turn you all into light eggs! " It pulls the multiplication sign and 1, 2, 3.9. They lean against each other, and they are all eggs.
It had nothing to do with multiplication, so I ran home dejectedly. On the way, they met division symbols, plus signs and minus signs. They refused to give in to each other. The division symbol said loudly, "In any case, I must use the multiplication symbol first, and you stand aside with the plus sign and the minus sign." Both the plus sign and the minus sign are in tears. At this time, the bracket came with a waist. It hugged the plus sign and the minus sign and said, "No way, I'm here to see who says he's still ahead." Multiplication and division can't see the brackets, so we have to pull over and let the brackets hold the plus sign and the minus sign first.
The mathematics kingdom has been noisy, making the little doctor of mathematics unable to sleep. It seems that everything has to wait for the doctor of mathematics to judge.
Math Kingdom Composition 12 One night, 0 and 1 walked together and they argued about a noisy math kingdom. 0 said, "I am the most important and biggest of all people." 1 smiled and said, "How is that possible? I am the most important. I am older than you. " None of them can convince anyone. At this time 1 calls the multiplication sign to judge, and 0 does not show weakness. He gathered all his brothers and sisters and stood with 1
Look at this line and say, "Oh, my God, it's so big! 1 0,100,1000,10000 ... ",1unconvinced. With a wave of his baton, he rushed to other friends for help. Take a look at the number, alas, there is no 1, all the lines have become 0 eggs, and 0 is not much. At this moment 1 came back, and behind him stood 2, 3, 4, 5, 6, 7, 8, 9. They all smiled and said: "0 Guangdan also said that he is the most important and he is the biggest!" " 0 was very angry and said, "It's useless to have many of you. I will turn you all into 0 light eggs! " "It pulls the multiplication symbol and 1, 2, 3...9, and they lean on it. It's over. It's really all zero eggs.
There is nothing I can do about multiplication. I ran home in frustration. On the way, I encountered division symbols, plus signs and minus signs. They gave in to each other. The division symbol said loudly, "In any case, the multiplication symbol and I have to go first. You stand aside with the plus sign and the minus sign." The plus sign and the minus sign were in tears. At this time, the bracket came over and inserted his waist. He hugged the plus sign and the minus sign and said, "No way, I'm coming to see who says he's the first." I can't help seeing the brackets in the multiplication and division method, so I have to stand aside and let the brackets hug the addition and subtraction signs first.
There have been quarrels in the field of mathematics, which has kept the little doctor of mathematics awake. It seems that everything has to wait for the doctor of mathematics to judge.
Mathematics Kingdom Composition 13 Recently, Mei Mei's mathematics scores have been declining one after another. What bothers her most is that her good friend's soft score has not reached 98. Mei Mei has been copying her questions to correct her mistakes, but recently she has ignored her softly.
Hey! Meimei sighed and fell asleep in bed. In the dream, she met an elf, and the elf said to her, I will arrange for you and your good friend to go to the math kingdom to let you know what friendship is. Before Meimei could speak, the elf flew away.
The next day, Mei Mei walked listlessly on his way to school. Suddenly, a gust of wind blew Mei Mei into the sky. Meimei saw her good friend Rourou and a door. Hello, we must open this door, or we will never get out. Rourou said. Oh! Meimei answered. A voice came from the door: I have a question. If you get it right, I'll let you out. Ok, you go! Meimei and Rourou said in unison. But Mr. Men wants to take them to the kingdom of mathematics, not the world of human beings. Mr. Men said: I spent 36 days traveling around the animal world. The circumference of the animal world is 252 kilometers. What is the speed every day? Meimei said: 252÷36=7 km/min. Rourou said: Your algorithm is wrong, it should be 252 ÷ 36 = 7km/day. Oh, Mei Mei answered. Mr. Man: Ha, that's right. You can go now. The door opened and Mei Mei ran happily (to be continued)
One day, there was a noise in the math court of the math kingdom. What happened? Let's have a look!
I saw eight symbols written by the author on the court chair:+,-,×, ⊙, ?, = and ≈. The judge said, "Please stand up for the mathematical symbols that have made mistakes recently." After a moment of silence, no one stood up. The judge said, "What is your responsibility?" My duty is to express approximate figures, and when decimals are difficult to express, I stand up. Then tell me what you did wrong! "I don't know myself, so I'll help." What you said is equal to, "3724÷ 100=37.24≈37, it will work!"
Last time, the king ordered you to deliver 3724 kilograms of sugar, each bag can hold 100 kilograms, but you insisted on 38 bags. Why? ""Don't you even understand that 38 is greater than 37.24? "greater than the number." Also, last time you took 100cm round steel, you can make one every 6cm. Obviously,100 ÷ 6 = 16.66 ≈17, but why only16? "It is equivalent to saying," If you only give me 37 sacks, what about the remaining 24 kilograms? "Did you throw it away?" Paused and said, "If 100cm round steel is used as 17, can the last one still be used?" Everyone has nothing to say about a series of rhetorical questions. It is equivalent to saying, "Some people engage in 1= 1.0, 1-0.9- 1 and still think that they are right. It is time to reflect." The judge said: "It is almost equal to doing well. As for what it says, 1= 1.0, 1-0.9, 0.9- 1, we will discuss it later. "
