A Complete Collection of Mathematics Humorous Stories in Grade Four 100 words.

Zhu Bajie, a wise fighter, said that Tang Priest and his disciples came to guo jia cun to learn Buddhist scriptures in the West and were warmly welcomed by the villagers. Everyone regards them as heroes of exorcism, not only taking photos with them, but also dragging them home. Facing the hospitality of the villagers, the teachers and apprentices felt very sorry, and helped them harvest crops, plow fields and rake fields whenever they had the chance. Pig Bajie just started to work hard for a few days, and after a few days he became lazy. He thinks it's too hard to work like this, and the master is more comfortable. As long as you sit and preach and recite Buddha, you will have everything. In fact, the master is nothing. If it weren't for the Monkey King's critical eye and skill, I'm afraid I couldn't even go to the Western Heaven, let alone learn from the Buddhist scriptures. If I have such an apprentice, I can do something, and then, haha, I can enjoy my retirement. So Bajie began to talk. Within a few days, he recruited nine apprentices, and he named them: Xiao Yi Huan, Xiao Er Huan ... Xiao Jiu Huan. It stands to reason that Bajie should concentrate on practicing and teaching his disciples now. However, he still did not change his bad habits, and often took his disciples out to eat and drink, which made the people complain. People are thinking about the good things they have done for everyone, and no one is embarrassed to complain to Wukong. In this way, Bajie people are even more fearless, eating five or six hundred steamed buns at a time, and the people are almost boiling. There is a girl named Ganoderma lucidum in the neighboring village. She is clever and kind, and often uses her wisdom to fight the wicked skillfully. Hearing this, she decided to punish Bajie. When she came to guo jia cun to open a restaurant, Bajie heard the news. Lingzhi girl pretended to be surprised and said, "Master Wuneng, it's a great honor for you to come to my restaurant. Come to my place for dinner in the future and don't go anywhere else. " She paused and said, "Here is a round table specially prepared for you. You ten people sit in a different order every time. When you complete all the orders, I will provide you with meals for free. But before that, every time you eat a meal, you should do a good deed for a villager in the village. What do you think? " Hearing this tempting suggestion, Bajie was so excited that they repeatedly said yes. So they always eat according to the agreed conditions and write down the seats. A few years later, new orders are still emerging, and Bajie is puzzled and has to ask Wukong for advice. Wukong couldn't help laughing when he heard this. "You idiot, you can't calculate such a simple account, and you still want to take advantage of it. You'll never get this free meal. " "Can't we get it after twenty or thirty years?" Wukong said, "Then I'll work out this account for you. Let's start with a simple number. Suppose there are three people eating. We gave them the serial numbers of 1, 2, 3, and there were six sequences, namely 123, 132, 2 13, 23 1 3 12, 3265433. If four people eat a piece of metal, the first person will sit still, and the seats of the other three people will change six times. When four people sit still as the first person in turn, the overall arrangement order is 6× 4 = 24. According to the same method, it can be inferred that if five people go to eat, there will be 24× 5 = 120 arrangements ... 10 people will have 3628800 different arrangements. Because you have to eat three meals a day, you can calculate the number of days to eat with 3628800÷3: 1209600 days, which is nearly 3320 years. Think about it, can this free leek be eaten? " After Wukong's calculation, Bajie suddenly understood the intention of Ganoderma lucidum girl and couldn't help feeling ashamed. From then on, Bajie often took his migrant brother to help the villagers. They regained people's love. Countermeasures for Winning During the Warring States Period, Qi Weiwang and General Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and thousands of dollars are bet on each horse race. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose. However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and got a daughter. This is an example of China's ancient substitution game theory to solve problems. Here is a game played by two people: take turns to report numbers, and the number reported cannot exceed 8 (nor can it be 0). Add up the figures reported by two people, and whoever reports more figures will win if the total is 88. If you were allowed to count first, how many times should you count first to win? Analysis: Because everyone reports at least 1 and at most 8 at a time, someone reports and another person will find a number, so the sum of this number and a reported number is 9. According to the rules, whoever counts and makes the sum 88 wins, so it can be inferred that whoever counts and makes the sum 79 (= 88-9) wins. 88 = 9× 9+7, and so on. Whoever counts 16 wins. Furthermore, whoever reports 7 first will win. Therefore, the winning strategy of the first whistleblower is: report 7 first, and then if the other party reports K( 1≤K≤8), you report (9-K). In this way, you will win if you quote 10. When does the snail climb up the well? A snail accidentally fell into a dry well. It lay at the bottom of the well and began to cry. A toad (Lai) crawled over and whispered to the snail, "Stop crying, little brother! It's no use crying. The shaft wall is too high. If you fall here, you can only live here. I have been here for many years, and I haven't seen the sun for a long time, let alone want to eat swan meat! " The snail looked at the old and ugly toad and thought, "What a beautiful world outside the well! I can never live in a dark and cold well like it! " The snail said to the toad, "Uncle toad, I can't live here. I have to climb up! "How deep is this well?" "Ha ha ha ..., are you kidding! The depth of this well is10m. How can you climb up with such a heavy shell at a young age? " "I am not afraid of suffering, not afraid of being tired. I can always climb out after a while every day! " The next day, the snail ate and drank enough and began to climb the wall. It kept climbing and finally climbed 5 meters at night. The snail was very happy and thought, "At this rate, I can climb up tomorrow night." Thinking about it, it fell asleep unconsciously. In the morning, the snail was awakened by a purr. At first glance, it turned out that Uncle Tu was still sleeping. It was surprised: "How come I am so close to the bottom of the well?" It turned out that this snail slipped 4 meters from the borehole wall after falling asleep. The snail sighed, gritted his teeth and began to climb again. At night, it climbed another 5 meters, but at night the snail slipped another 4 meters. Climb and climb, and finally the strong snail climbed up the well platform. Children, can you guess how many days it will take a snail to climb the drilling platform? Recently, a new waiter came to the "Mathematics Store". It is Xiao's Four. One day, Little "3" went to the math shop and bought a pencil. The little "4" said, "You have to pay 1 54 yuan." Little "3" paid 1 yuan 50 cents and asked, "How can I pay 4 cents?" Little "4" quickly said, "You don't have to pay the 4 cents." Little "3" asked doubtfully, "So you're not going to suffer?" "No, this is a rule of our shop, called" rounding ". Anything less than 4 cents is discarded. If it is more than 5 cents, it will be 1 cent. " Little "4" kindly explained. Little "3" said happily, "Thank you, that's very kind of you!" "Yes, I like 4 very much, too." "25" ran over and said, "Because 25×4= 100, it is relatively simple to calculate, for example, 25×87×4=25×4×87, isn't it fast and simple to calculate? ! ""Yes, it's really quick and easy. I also like 4. " It turned out to be "29" and "25" and quickly asked, "Hey, how can you like' 4'?" "No.29" said unhurriedly, "You don't know this. Generally speaking, February is 28 days. February is only 29 days when the Gregorian calendar year is a multiple of 4. It's only my turn once every four years. Sure, I like' 4'. However, the Gregorian calendar year is one hundred, and it must be a multiple of 400. There are only 29 days in February. This year is called leap year. " "Ah, the use of' 4' is really great!" "25 exclaimed. This "4" waiter is really a very gentle and likable waiter. Pig ate some peaches and went to Huaguoshan to find Wukong. The Great Sage was not at home. The little monkeys warmly entertained Bajie and picked 100 of the most delicious peaches in the mountains. Bajie said happily, "Let's eat together!" How to eat? Counting ***30 monkeys, Bajie found a branch and drew it on the ground, and listed the formula, 100 ÷ 30 = 3... 1. Bajie pointed to the above three monkeys and said generously, "Each one can eat three pecans. Listen, I'll eat the remaining 60. The little monkeys were very grateful to Bajie. They thanked him one by one, and then each took his share. When Wukong came back, the little monkeys told Wukong how generous Bajie was today and why he only ate a pecan. Seeing Pig's arrangement, Wukong shouted, "What a fool! I'll find him! "Ha ha, do you know how many peaches Bajie ate? The origin of Arabic numerals Xiaoming is a child who likes to ask questions. One day, he became interested in the numbers 0-9: Why is it called "Arabic numerals"? So he went to ask his mother, "Since 0-9 is called Arabic numerals, it must have been invented by Arabs, mom?" Mom shook her head and said, "Arabic numerals were actually invented by Indians." "About 1500 years ago, Indians used a special word to represent numbers. There are 10 words, and you can write both strokes. Later, these figures were introduced into Arabia. Arabs think these numbers are simple and practical, so they are widely used in their own countries and spread to Europe. In this way, it gradually became the number we use today. Because Arabs have played a great role in spreading these figures, people are used to calling them' Arabic numerals'. " Xiao Ming heard this and said, "So that's it. Mom, can this be called' making a mistake'? " Mom smiled. Children's Song Competition The animal school held a children's song competition, with the elephant teacher as the referee. The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." "If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce the ten digits, the ten digits will be reduced again and again. " Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them. A long time ago, the kingdom of mathematics was quite chaotic. The 0-9 brothers not only dominate the kingdom, but also boast of their greatest skills. The math angel was very angry when he saw this situation. He sent three little angels to the math kingdom to establish order and avoid chaos. Three little angels came to the kingdom of mathematics, and 0-9 brothers looked at them contemptuously. Q: "What are you three doing in the kingdom of mathematics? You are not welcome! " = Laugh and say, "We are judges sent by angels to help you govern your country. I am an equal sign, and these two are' greater than sign' and' less than sign'. Whoever they speak to is greater. Whoever they point to is small. " When the ten brothers heard that they were judges sent by angels, they obeyed the order of sum = obediently. Since then, the mathematical kingdom has a strict order, and no one will violate it. Bear opens a shop Bear doesn't like studying, just wants to do business, so he opens a fruit shop next to the school. Rabbit and monkey are his classmates. They have agreed to teach this lazy guy who doesn't like school. They came to bear's fruit shop. "How much are the peaches?" Asked the little monkey. "The first basket is 6 yuan and 3 Jin, and the second basket is 6 yuan and 2 Jin." The bear replied. The little monkey said, "If I take 5 kilograms from two baskets, I will pay you 12 yuan, right?" The bear nodded. "That I want it all. Since 5 kg is 12 yuan, then 60 kg is 12× 12= 144 yuan, right? " "Exactly, exactly." Said the bear. So the little monkey bought all the peaches, paid the money and left happily with the little rabbit. When I get home at night, the bear pays the bill, which is a loss anyway. The next day, the little monkey and the little rabbit found the little bear and told him the situation. They smiled and said, "It's all because you don't study well that we came to teach you a lesson." They replenished the little money to the bear. Bear hung his head in shame, and since then, he has been very serious in class every day. The three of them became good friends. One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Huaguoshan to pick peaches. Soon, the three disciples came back happily after picking peaches. Tang Priest and his disciples asked: How many peaches did each of you pick? Bajie said with a silly smile, Master, let me test you. Each of us took the same amount of money. There are less than 65,438+000 peaches in my basket. If we count three peaches, there are 1 peach left in the end. Do the math. How many did each of us choose? Friar Sand said mysteriously, Master, I will test you, too. If there are four peaches in my basket, there is 1 left in the end. Do the math. How many did each of us choose? Wukong smiled and said, Master, I'll test you, too. If there are five peaches in my basket, there will be 1 in the end. Do the math. How many shall we each choose? Tang Priest quickly said the number of peaches he had picked. Do you know how many peaches each of them picked? A young man came to see Mr. Liu and introduced himself: "My name is Yu Jiang. I'm taking a tour group to Hong Kong this time. I heard that your hotel has a comfortable environment and good service. We want to stay in your hotel. " Mr. Liu quickly said enthusiastically: "Welcome, welcome. I wonder how many people are there in your group? " "People, well, it's a big group." Mr. Liu was overjoyed: it's great to have big groups and enterprises. As a tour guide, Yu Jiang saw Mr. Liu's mind. He said slowly, "Sir, if you can count the number of people in our group, we will stay in your hotel." "Please go ahead." Mr Liu said confidently. "If I divide my group into four groups, one more person, and then divide each group into four, there will be one more person, and then four groups will be divided into four, there will be one more person, including me, of course. How many people are there at least? " "How much is a * *?" Mr. Liu immediately thought of it. He must take over the business. "Without specific figures, how to start?" He was a shrewd businessman and quickly replied, "At least 85 people?" Mr. Yu Jiang said happily, "Exactly, it's eighty-five. Please tell me about your algorithm. " "The least number of people is the last quartile, and each is one person. It can be inferred that the third quartile is preceded by 1×4+ 1=5 (person), and the second quartile is preceded by 5×4+ 1=2 1 (person). " All right, we'll stay with you today. ""How many men and women do you have? " "There are 55 men and 30 women." "We only have rooms for 1 1, rooms for 7 people and 5 people. How do you want to live? " "Of course, Sir, you have arranged, but men and women must be separated, and there can be no empty beds. "There will be a problem. Mr. Liu has never met such a guest, so he has to spend more time. After thinking hard, he finally came up with the best plan: 1 1 two people, seven people in four rooms, five people in one room; One female room 1 1 person, seven people in two rooms, five people in one room, and one room * * *1/. After seeing his arrangement, Mr. Yu Jiang was very satisfied and immediately went through the accommodation formalities. Made a big deal. Although it is a bit complicated, Mr. Liu is still very happy in his heart. The Clever Boy Once upon a time, there was a king who often amused the ministers around him with difficult questions. If the ministers do it right, he will give them a little reward with a little kindness. If you can't answer, you will be punished or even beheaded. One day, the king pointed to a pond in the palace and asked, "I will give jewels to anyone who can tell how many buckets of water there are in the pond." "If you can't say it, I will' reward' each of you with 50 whips." Ministers were stumped by this sudden question. Just as the ministers were in confusion, a little boy came over to herd cattle. He asked what happened and said, "I want to meet this king." The ministers brought the little boy before the king. Seeing the little boy in front of him was black, thin and small, the king said doubtfully, "If you can't answer this question, you will be beheaded, you know?" Everyone present made a sweat for the little boy, but the little boy answered the king's question unhurriedly. In desperation, the king gave the little boy a gem award. Children, do you know what he answered? In fact, the king is a problem of insufficient conditions. It is impossible to find the right answer in normal thinking mode. The little boy just caught the key. He replied like this: "it depends on the size of the bucket: if the bucket is as big as the pond, it is a bucket of water;" If the bucket is only half the size of the pond, there are two buckets of water; If the bucket is one-third the size of the pond, it is three buckets of water ... "The little boy actually broke the habitual thinking mode and analyzed the specific problems. How clever and flexible his mind is! Chen Jingrun, a mathematician triggered by a story, is a famous mathematician. He has made great contributions to overcoming Goldbach's conjecture and founded the famous "Chen Theorem", so many people affectionately call him "the prince of mathematics". But who would have thought that his achievement originated from a story? From 65438 to 0937, diligent Chen Jingrun was admitted to Huaying College in Fuzhou. One day, Teacher Shen Yuan told us a story in math class: "A Frenchman discovered an interesting phenomenon 200 years ago: 6=3+3, 8=5+3, 10=5+5, 12=5+7, 28=5+23. Every even number greater than 4 can be expressed as the sum of two odd numbers. Because this conclusion has not been proved, it is still a guess. Euler said: Although I can't prove it, I am sure this conclusion is correct. From then on, Chen Jingrun became interested in this wonderful question. In his spare time, he likes going to the library. He not only read the counseling books in middle schools, but also eagerly read the textbooks of mathematics and physics courses in these universities. Come on, 1 Zhe Bajie
