Ⅰ Mathematics in Life Stories 7 stories, no less than 400 words,

This afternoon, my mother and I went to the supermarket to buy things.

When we finished buying what we needed and were about to leave, I saw ham sausages on the shelves, so I asked my mother to buy some ham sausages, and my mother agreed. But just after walking a few steps, I saw packs on the shelf again, of the same brand, same weight, containing 10 sticks, priced at 4.30 yuan per pack. Should I buy a pack or a stick? I hesitated. Suddenly, my mind turned around, I just need to compare and buy whichever one is more cost-effective. So I started to calculate: if I buy 10 pieces at retail, each piece costs 4 jiao, which is 40 jiao, which is equal to 4 yuan, and the whole package costs 4.30 yuan, which is 3 cents more, so I decided to buy it in bulk. I told my mother my calculation process, and she praised me for loving to use my brain. Also, tonight, I saw a confusing math problem. The title is: 37 students want to cross a river. There is an empty boat at the ferry that can only hold 5 people. If they all want to cross the river, how much should they use at least this boat? Second-rate?

Careless people often ignore the "empty boat", that is, they forget to have a punting boat, so they can only take 4 people at a time. In this way, there are 37 people minus one classmate who punts the boat, leaving 36 students. 36 divided by 4 equals 9. The last classmate who worked as a boatman on the other side also went ashore 4 times, so it takes at least 9 trips.

1. Mathematical Stories - Making Change

A customer came to a cane store and bought 30 yuan. A cane. He took out a 50 yuan note and asked for change.

There happened to be no change in the store. The shopkeeper went to a neighbor to change the 50 yuan note into change and gave the customer 20 yuan in change.

As soon as the customer left, the neighbor rushed over in a panic and said that the 50 yuan note was fake. The shop owner had no choice but to pay the neighbor 50 yuan in compensation. Then he went out to chase the customer and caught him and said: "You liar, I will pay 50 yuan to my neighbor and give you 20 yuan in change. You took another cane. You have to compensate me 100 yuan." "Loss."

The customer said: "The cost of a cane is the 30 yuan you left when the neighbor gave you change, so I only took 70 yuan from you."

Could you please calculate, what is the real loss of the cane store? I should add here that the cost of the cane is 20 yuan. If this customer is successful in defrauding, how much money did *** get from defrauding him?

2. Story: Monkey fishing for his hat

A group of monkeys were playing by the well. A gust of wind blew one monkey’s hat into the well. He called 18 friends and came from the well. Fang Zishang went to fish out the hats one by one. Four monkeys did not go up the tree, so they fished out the hats. He asked: How many monkeys went up the tree and went down the well to fish out the hats together?

3. Story: When did the snail climb up the well?

A snail accidentally fell into a dry well. It lay on the bottom of the well and cried. A toad came over and said angrily to the snail: "Stop crying, little brother." , There is no point in crying, the wall of this well is high and slippery, I can only live here if I fall here. I have lived here for many years. The snail looked at the old and ugly toad and thought to himself: "Outside the well." How beautiful the world is! I could never live like that in a dark, cold well. The snail said to the toad, "Uncle Legg, I can't live here. I have to climb out. How deep is this well?" "Hahaha... What a joke. This well is 10 meters deep. You are so young." How could he climb out with such a heavy shell on his back? "I'm not afraid of hardship or tiredness. If I climb a section every day, I can always climb out!" "The next day, the snail was full and started to climb up the well wall. It kept crawling and crawling. In the evening, it finally climbed 5 meters. The snail was very happy and thought to itself: "Like this. Speed, I can climb out tomorrow evening. "Thinking about it, he fell asleep unknowingly. In the morning, the snail was woken up by a burst of snoring. When he saw it, it turned out to be the leprous uncle who was still sleeping. He was shocked: "Why am I so close to the bottom of the well? "It turned out that after the snail fell asleep, it slid down 4 meters from the well wall. The snail sighed, gritted its teeth, and started to climb up again. In the evening, it climbed another 5 meters, but at night, the snail slid down again 4 meters. Mi, just like this, crawling and sliding, finally the strong snail finally climbed up the well platform. Smart children, can you guess how many days it took the snail to climb up the well platform?

Animal Mathematics

Meteorologist Lorenz proposed a paper called "Will a butterfly flap its wings? Taxas State Caused a Tornado?" He discussed that if the initial conditions of a certain system are just a little worse, the result will be very unstable. He nicknamed this phenomenon the "butterfly effect." Just like when we throw a dice twice, no matter how deliberately we throw it, the physical phenomenon and the number of points thrown twice are not necessarily the same. Why did Lorenz write this paper?

This story happened one winter in 1961. He was operating the weather computer in the office as usual.

Normally, he only needs to input meteorological data such as temperature, humidity, and pressure, and the computer will calculate the possible weather data at the next moment based on three built-in differential equations, thus simulating a weather change map.

On this day, Lorenz wanted to learn more about the subsequent changes in a certain period of record. He re-entered the weather data at a certain time into the computer and let the computer calculate more subsequent results. At that time, the computer processed the data several times, which was enough for him to drink a cup of coffee and chat with friends for a while before the results came out. An hour later, the results came out, but he was stunned. Comparing the results with the original information, the initial data is almost the same. As the later stages progress, the data differences become even greater, just like two different pieces of information. The problem was not with the computer. The problem was that the data he entered was off by 0.000127, and these slight differences made a huge difference. Therefore, it is impossible to accurately predict the weather in the long term.

2. Mathematics “geniuses” among animals

Bee hive It is a strict hexagonal column with a flat hexagonal opening at one end and a closed hexagonal rhombus-shaped bottom at the other end, composed of three identical rhombuses. The obtuse angle of the rhombus that makes up the chassis is 109 degrees 28 minutes, and all acute angles are 70 degrees 32 minutes, which is both strong and material-saving. The wall thickness of the hive is 0.073 mm, and the error is extremely small.

Red-crowned cranes always fly in groups and form a "human" shape. The angle of the "herringbone" shape is 110 degrees. A more precise calculation also shows that half of the angle between the "herringbone" shape - that is, the angle between each side and the direction of the crane group's advance is 54 degrees, 44 minutes and 8 seconds! The angle of the diamond crystal is exactly 54 degrees, 44 minutes and 8 seconds! Is it a coincidence or some kind of "tacit understanding" of nature?

The "Bagua" shaped web made by spiders is a complex and beautiful octagonal geometric pattern. Even if people use a straight edge and compass, it is difficult to draw a pattern as symmetrical as a spider web.

In winter, cats always hug their bodies into a spherical shape when sleeping. There is also mathematics in this, because the spherical shape minimizes the surface area of ??the body and thus dissipates the least heat.

The real mathematical "genius" is the coral polyp. Coral polyps keep a "calendar" on their bodies. They "carve" 365 stripes on their body walls every year, apparently "painting" one stripe a day. Strangely, paleontologists discovered that coral polyps from 350 million years ago "painted" 400 "watercolor paintings" every year. Astronomers tell us that at that time, the Earth's day was only 21.9 hours long, and a year was not 365 days, but 400 days. (Life Times)

Ⅳ An essay about mathematics in life, with a limit of 400 words or less

Today is a really nice day! My mother and I are going to go shopping at Jiasheng Plaza opposite the community.

When we arrived at Xinhe Supermarket in Jiasheng Plaza, my mother wanted to buy

a bottle of dish soap, so we walked to the dish soap

section. At this time, my mother said to me: "I want to buy now

a bottle of citrus dishwashing liquid. There are different weights here.

Let me test you, which one is the most affordable. I Just buy the most affordable one." I thought to myself: What's so difficult about this? I'll know just by looking at it. I glanced over and eliminated many bottles, leaving only two bottles.

I thought about it, looked at it carefully, and found that

Although the two bottles of dish soap were about the same size, the packaging paper

said The weights are different: one says 1.5 kilograms; the other says 1.3 kilograms. And their price is 12 yuan, of course the 1.4kg bottle is cheaper. I said to my mother: "This bottle is the cheapest, just buy this bottle." At this time, my mother took another bottle of washing liquid and said to me with a smile: "This bottle is 1.5 kilograms,

12.9 yuan, this bottle is the cheapest." I took a closer look, and it turned out that it was a super special price, oops! Miscalculated.

Life is full of mathematics. If you are not careful

you will make mistakes. We must learn mathematics well.

Ⅳ Mathematics stories in life. short!

1. There once was a herdsman who had one unfinished business before his death, that is, he wanted to divide 117 sheep among his three sons, so he made a will: "Give 1/2 to the third son and 1/2 to the third son." Give 1/3 to the second oldest and 1/9 to the oldest." After the herdsman dies. The three sons didn't know how to share 1/3, so they went to ask a neighbor for advice. The smart neighbor took one of his big and fat sheep to share it for them. Together with this sheep, there are a total of eighteen sheep, the third oldest gets 9, the second youngest gets 6, and the eldest gets 2. After the three brothers took away their assigned sheep, the neighbor happily took his big, fat sheep home.

2. A moment of relaxation: A Burmese farmer divided chickens for the king

There was a poor farmer in Burma who hoped to become rich one day.

One day he took a rooster and offered it to the king.

The king smiled and said: "A rooster is a small gift to me. I have a family of six: me, the queen, my two sons and two daughters. How do we divide this rooster?" ?"

The farmer cut off the chicken head and presented it to the king, saying, "Your Majesty is the head of a country, so please accept this generous gift." Then he cut off the meat from the chicken's back and said, " This one is dedicated to the queen, who carries the burden of the whole family." He cut off two chicken feet and said, "These two will be given to the two princes. They will follow in your footsteps and ascend to the throne of ruler."

Then he cut off two wings and said: "Let each of the two princesses get a wing, because when they get married one day, they will fly away with their husbands. The remaining part belongs to me, Because I am your Majesty's guest, and the master has the obligation to entertain the guests with the best food."

The king was very satisfied with the farmer's witty answer, and rewarded him with many gold, silver and precious stones. A greedy man, after learning about the farmer's fortune, came to the palace with five roosters and said to the king: "I would like to present five roosters to express my greetings to Your Majesty."

A glance from the king He saw the man's intention and said, "I am happy to accept your five roosters, but there are six people in my family. If you can give them to us fairly and reasonably, I will reward you greatly." Greedy men don't know how to distribute. He regretted that he should have brought six roosters instead of five.

The king sent someone to summon the farmer and let him share it.

The farmer said calmly: "Your Majesty, this is easy to do: one rooster is dedicated to Your Majesty and the Queen, the other is dedicated to the two princes, and the third belongs to the two princesses. The remaining two The rooster belongs to myself, because I am His Majesty's guest. This is the only reasonable way to distribute the rooster, because His Majesty, the Queen and the other rooster add up to three, and His Majesty's two princes and one rooster add up to three. Your Majesty’s two princesses and a rooster add up to three, and the remaining two roosters and I also add up to three. “The king was very satisfied and rewarded the farmer with two roosters and a large reward. But the man who was greedy for money returned empty-handed and disappointed.

Ⅵ Asking for a 400-word essay on mathematics in life

Mathematics in life

The weather was sunny today. I went to the supermarket to go shopping. I saw a lot of things when I went in. . So I started shopping like crazy. Soon my basket was full, so I asked my dad, "Can you calculate the things here?" Dad touched his head and said, "Who can calculate so many things at once?" I can. My head was tired from all the calculations, so my father came up with a good idea to ask the cashier to help us.

He came to the cashier and said to the aunt, "Can you help me?" Shall I do the math? It is too difficult for us to calculate verbally. Please help us do the math. It worked out after a while. I praised repeatedly and said: "Okay, that's great." I asked auntie how you did it. Auntie said: "Such a small thing is not difficult for me." I relied on my mobile phone to do all the calculations. I asked myself how could I be so stupid? I didn’t expect this. We cleaned up and left. I kept thinking why did Auntie know this? I was confused. How could my aunt have thought of this and I couldn't?

When I returned home, I realized that there is mathematics in life, just like what happened today, there is mathematics. For example, if you are calculating a lot of things and you can’t figure it out, just use a calculator. If you don’t have a calculator, you can also use a mobile phone to calculate the numbers. Wouldn’t that solve the problem? All math-related things must be solved with the brain.

Therefore, life cannot be separated from mathematics. If you encounter difficulties in mathematical calculations, use your brain to find a solution.

Ⅶ Mathematics Stories in Life

In the evening, I saw a difficult problem in the Olympiad book: There are three times as many apple trees as pear trees in the orchard. Master Wang gives 50 apple trees and 20 pear trees were fertilized. After a few days, all the pear trees were fertilized, but there were still 80 apple trees that were not fertilized. I would like to ask: How many apple trees and pear trees are there in the orchard?

I was not intimidated by this question, the difficult questions stimulated my interest. I think that apple trees are three times as large as pear trees. If both trees are to be fertilized on the same day, Master Wang should fertilize "20×3" apple trees and 20 pear trees every day. In fact, he only fertilized 50 apple trees every day, a difference of 10 trees, and finally a difference of 80 apple trees. From this, we can know that Master Lao Wang has been fertilizing for 8 days. There are 20 pear trees in one day, which means 160 pear trees in 8 days. Based on the first condition, we can know that there are 480 apple trees. This is to use the idea of ????hypothesis to solve problems, so I think the hypothesis method is actually a good way to solve problems.

Ⅷ A short story of a mathematician, 400 words

When Hua Luogeng was in elementary school, a teacher introduced the school to the new teacher and said that the students in this school were all from poor families. Most children are idiots... These words deeply hurt Hua Luogeng's heart, and he was determined to repay the teacher with excellent results.

One day, the math teacher gave everyone an interesting problem: "There is something that I don’t know how many there are. If you count three or three, you will get two. If you count five or five, you will get three." "There are two left after counting seven to seven."

The whole class looked at each other and couldn't answer. Only Hua Luogeng stood up and said, "Teacher, I know, yes." '23'." The whole class was shocked, and the teacher nodded in praise. From then on, he fell in love with mathematics class.

While he was studying, the business of his father's shop was declining and he could no longer afford to continue his studies, so he had to drop out of school and work at the counter. He started self-study using an algebra book, a geometry book, and a calculus book with only 50 pages left. There was no time during the day, so at night I watched the small oil lamp and calculated over and over again. His father called him a "nerd" and forced him to burn his books several times. His neighbors also persuaded him to do business well.

Unfortunately, he suffered from terrible typhoid fever again. The doctor shook his head and sighed and asked his family to prepare for his "future". He challenged the god of death, struggled to work in the fields, and his left leg was broken again and became disabled. He was not discouraged and continued to exercise with a cane and endured the pain. After practicing enough to walk, he went to a middle school to do chores, fetching water for the teacher and sharpening pencils. Even so, he did not give up self-study.

Not long after he started working in a middle school, he began to submit mathematics papers to newspapers and periodicals, and he was not discouraged even after they were rejected many times. Later, he published the article "The Reasons Why Su Jiaju's Algebra's Solution to the Quintic Equation Cannot Be Established", which won the appreciation of Xiong Qinglai, the master of mathematics, who quickly introduced him to Tsinghua University and placed him next to him.

Hua Luogeng’s growth history

Born on November 12, 1910 in Jintan District, Changzhou, Jiangsu Province, he was a child. He loves to use his brain all the time, and is often nicknamed "a fool" by his peers because he is too attentive in thinking about problems. In 1922, after graduating from Renyuan Primary School in the county town at the age of 12, he entered Jintan County Junior High School. Teacher Wang Weike discovered his mathematical talent and tried his best to cultivate it.

In 1925, after graduating from junior high school, he enrolled in Shanghai Zhonghua Vocational School. He dropped out of school because he could not afford the tuition. He dropped out and went home to help his father run a grocery store. Therefore, he only had a junior high school diploma in his life. After that, he spent 5 years studying all the mathematics courses in high school and junior college by himself.

In the autumn of 1927, he married Wu Xiaoyuan. In the winter of 1929, he unfortunately contracted typhoid fever and his left leg was permanently disabled and he had to use a cane to walk. In 1929, Hua Luogeng was employed as a clerk at Jintan Middle School and began to publish papers in Shanghai Science and other magazines.

In the spring of 1930, Hua Luogeng published "The Reasons Why Su Jiaju's Algebraic Solution to the Quintic Equation Cannot Be Established" in the Shanghai "Science" magazine, which caused a sensation in the mathematics community. In the same year, Xiong Qinglai, the director of the Department of Mathematics at Tsinghua University, learned about Hua Luogeng's self-study experience and mathematical talent, and broke the rules and allowed Hua Luogeng to join the Tsinghua University Library as a librarian.

In 1931, he served as an assistant in the Department of Mathematics at Tsinghua University. He taught himself English, French, German, and Japanese, and published three papers in foreign magazines. In 1933, he was promoted to assistant coach. In September 1934, he was promoted to lecturer.

"Mathematics in Life" composition, 400 words

Air is everywhere , and it has no taste at the same time, but we are indispensable for it. The same is true for mathematics. The great mathematician Hua Luogeng once said: "The universe is as big as the particles are as small as rockets, the ingenuity of chemical engineering, the convenience of the earth, and the complexity of daily life. Mathematics is used everywhere." From the time we were born, mathematics has surrounded us. around. Full moon, hundred days, one year old... Count of increasing age. When I grow up, I begin to receive systematic education in mathematics, learning counting, addition, subtraction, multiplication and division.

When buying groceries, giving and changing money is mathematics; when cutting paper, the size and area of ??the paper is mathematics; when eating, distributing food equally to everyone is mathematics. I remember the first time I went to the vegetable market to buy vegetables. While choosing the vegetables that I and my parents loved to eat, I calculated the accounts carefully, and the last payment was correct. Also, when I went to the supermarket for the first time, I budgeted carefully and bought a lot of food and daily necessities.

By using mathematics, some troubles can always be simplified and easily solved. When learning chess, how do you describe moves? After you mark the lines on the chessboard with numbers, you can use simple chess records such as "Run two draws five" and "Rook three draws four" to completely describe a game of chess. It is precisely because of the game records that blind chess exists.

Mathematics is like a treasure buried in the ground. We need to dig out slowly. To learn mathematics well, we must be rigorous and practical and have the courage to try. When I encounter difficulties in my studies, I will dig out the implicit conditions in the question, such as years, months, time in the day, the sum of the interior angles of a triangle, etc., and look for ideas to solve the problem. Once I learn how to use it, I will be pleasantly surprised to find that I have mastered another skill, and I will be excited to discover the next puzzle and can't wait to solve it.

Mathematics exists everywhere, and we use mathematics in our lives, which provides great convenience for our lives; teachers connect mathematics with work, providing them with the ability to complete their work satisfactorily. Guarantee; scientists have combined mathematics and science and made great contributions to the improvement of our scientific and technological level.

Mathematics is like air, tasteless, but it is an indispensable and important existence for us to study, live, work and develop science and technology.

Ⅹ "Mathematics in Life" essay is about 400 words, urgent, urgent, who can help me

Mathematics in Life

I saw it on TV today Many people donate money to those who are not educated, and I think of it: There are about 1.3 billion people in my country. If everyone saves 1 dime a day, our country will save 13 million yuan, and everyone will save 10 cents a day. It costs more than 10,000 yuan to go from primary school to college. Based on this calculation, 1085 can be used for children who are not in school. How great it would be to give this money to those children! If I had so much money, I would share it equally with the children!

I suddenly remembered that there are disadvantages to having more people and more power, thank you! Because if each person wastes an extra 1.3 billion water every day, it would be ridiculous!

I did a little experiment: 1,000 drops of water weighed 200 grams under the faucet, and I calculated again: 1300000000 divided by 1000 times 200 equals 260000000 grams, and then 260000000 equals 260 A ton of water is enough to last 2 or 3 years! I asked my parents: "Can 1 ton of water generate 100 kilowatt-hours of electricity?" I thought about it and figured it out, which means that 260 tons of water can generate 26,000 kilowatt-hours of electricity.

Wow! I was stunned for five minutes. 260 tons of water can actually produce so many effects! So from now on, we all must save water and use water. Don’t waste a drop of water. We must develop the good habit of saving and not waste it!

I believe that mathematics is everywhere in life, and mathematics is used everywhere. As long as a person is dedicated to learning mathematics, he can experience the joy of mathematical thinking even in games! ! !
