Supermarket Experience Mathematics Story 400 words
"One" 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.
『二』 Asking for a 400-word essay on mathematics in life
Mathematics in life
The weather was sunny today. I went to the supermarket to shop. I saw something as soon as I entered. Lots of stuff. 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.
『三』 Mathematical fairy tale (about 400 words) Urgent! urgent! urgent! I'm about to go to school and I want to use it as a reference
In the mysterious kingdom of mathematics, the fat "0" and the thin "1" are two "little famous" numbers. , often arguing over who is important. Look! Today, these two young enemies met on a narrow road and started another war of words with each other.
The thin man "1" spoke first: "Hmph! Fat '0', what's so great about you? Just like 100, if it weren't for me, the thin man '1', you two fat '0's What's the use?"
Fatty "0" was unconvinced: "Don't show off in front of me. Think about it, if you didn't have me, where would you find other numbers to make 100?"
"Yo!" "1" was not to be outdone, "No matter how arrogant you are, you just show that you have nothing. Look! '1+0' is not equal to me. How can you be useful?" "
"Go! The result of '1×0' is not me, and your '1' is also useless!" "0" tit for tat.
"You..." "1" paused and said accordingly, "Anyway, your '0' means nothing!"
"This is your knowledge. "Missing." "0" said calmly, "Look, in daily life, if the temperature is 0 degrees, does it mean there is no temperature? For example, if there is no me as the starting point on the ruler, how can you be '1'? ?"
"No matter how you compare, you can only do the middle number or the last number, such as 1037, 1307, and you can never take the lead." "1" said confidently. After hearing this, "0" said even more confidently: "It's not certain. For example, 0.1, what will you do without me, '0', to occupy the place?"
Seeing the fat man "0" and the skinny "1" were in a red-faced fight, neither giving in to the other. The other numbers watching the battle were very anxious. At this time, "9" had an idea and stepped forward with a pause gesture: "You two, stop arguing. Look at you, which number is bigger than me, '1' or '0'?" "This..." Fatty "0", thin man "1" was speechless.
At this time, "9" calmly said: "'1', '0', in fact, as long as you stand together, aren't you bigger than me?" "1" and "0" looked at each other, scratching their heads after a long while. The head smiled. "That's right! The power of unity is the most important!" "9" said sincerely.
『四』 A short mathematical story of 400 to 500 words
The story of the mathematician Gauss when he was a child
Adding from one to a hundred
< p> Gauss has many interesting stories. The first-hand information of the stories often comes from Gauss himself, because in his later years he always liked to talk about what happened when he was a child. We may doubt the authenticity of the stories, but many people have confirmed what he said. Talk about stories.Gauss's father was the foreman of a brickwork factory, and he always had to pay wages to the workers every Saturday. In the summer when Gauss was three years old, when he was about to pay his salary, little Gauss stood up and said, "Dad, you made a mistake." Then he said another amount. It turned out that the three-year-old little Gauss was lying on the floor, secretly following his father to calculate how much wages should be paid to whom. The recalculation results proved that little Gauss was right, which shocked the adults standing there with their mouths open.
Gauss often said with a smile that he had learned to calculate before he learned to speak. He also often said that he learned to read by himself after asking adults how to pronounce letters.
At the age of seven, Gauss entered St. Catherine Elementary School. When I was about ten years old, my teacher gave me a difficult problem in arithmetic class: "Write down the integers from 1 to 100, and then add them up!" Whenever there was an exam, they had the following habit: the one who finished first Just put the slate (common at that time, used for writing) face down on the teacher's desk. The second person who finished finished placed the slate on the first slate, and they fell one by one. Of course, this problem will not be difficult for people who have studied arithmetic progressions, but these children have just begun to learn arithmetic! The teacher thought he could take a break. But he was wrong, because in less than a few seconds, Gauss had already put the slate on the desk and said at the same time: "Here is the answer!" The other students added up the numbers one by one, sweat broke out on their foreheads, but Gauss sat quietly, paying no attention to the contemptuous and suspicious eyes cast by the teacher. After the exam, the teacher checked the slates one by one. Most of them did it wrong, and the students were whipped. Finally, Gauss's slate was turned over, and there was only one number on it: 5050 (Needless to say, this is the correct answer.) The teacher was surprised, and Gauss explained how he found the answer: 1+100=101, 2+99= 101, 3 + 98 = 101, ..., 49 + 52 = 101, 50 + 51 = 101. There are 50 pairs in a day and the sum is 101, so the answer is 50 × 101 = 5050. It can be seen that Gauss found the symmetry of the arithmetic series, and then put the numbers together in pairs just like the process of finding the sum of general arithmetic series.
『五』Give me some essays about mathematics in life, no less than 400 words
In daily life, everything is inseparable from mathematics. It can be seen how closely related mathematics is to us.
For example, when my mother goes to the street to buy fruits and vegetables, she also goes to the printing press to copy manuscripts...etc., all of which require mathematics. There are many interesting mathematics in life, waiting for us to discover and explore.
During the summer vacation, my parents and I went to my cousin's house to play. We got thirsty on the way, so my father had to go to a nearby grocery store to buy mineral water. There is a rule in the grocery store: if you buy 3 bottles of mineral water, you can exchange it for one bottle of mineral water. A bottle of mineral water sells for 1 yuan. When my father saw it, he took out 10 yuan and gave it to the grocery store owner and said, "Boss, buy 10 bottles of water." , got the water, I drank it eagerly, and drank two bottles in a while. Before I could recover, there were already several empty bottles. Dad asked me: "Lingling, how many bottles of mineral water can we exchange for 10 yuan?" I thought: After drinking 10 bottles of water, I exchanged 9 empty bottles for 3 bottles of mineral water, and exchanged 3 empty bottles for 1 Bottles of mineral water...and two empty bottles left. I happily said to my father: "Dad, I calculated it. It is 14 bottles of mineral water, and there are 2 empty bottles left." Dad smiled and said, "Think again!" I thought thoughtfully: " We can borrow another empty bottle from the grocery store owner and return the empty bottle to the owner after drinking. Oh! We can drink 15 bottles of mineral water." Dad nodded in praise.
Mathematics means to use it flexibly and connect theory with practice. Only by mastering mathematical knowledge can mathematics serve us better. So we must learn mathematics well and make mathematics a good helper in our study and life
"Lu" A short story of a mathematician in 400 words
When Hua Luogeng was in elementary school, a teacher told the new employee When the teacher introduced the situation of the school, he said that the students in this school were all children from poor families, and most of them were 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.

『八』 A short mathematical story about shopping
Counting soybeans
Today’s math lesson is a practical activity. We are divided into groups of 8 people. Next The members of each group worked together to find ways to estimate how many grains of soybeans there are in 1 kilogram. According to the estimation method introduced in the book, it seems not difficult, but to minimize the error, you have to be serious.
I originally suggested that the group use a cup to measure more accurately. But the cup could not be found. Later, the group chose the method of grabbing by hand. Team member Luo Guangyuan was responsible for catching it. Oops! Luo Guangyuan’s little hands are quite good. It's big! There are 180 grains in one catch, and I caught 1 kilogram of soybeans after 30 consecutive catches. Finally, I'm done. 30 180s equal 5,400 grains. In this way, I know that there are approximately 5,400 grains in 1,000 soybeans.
I was inspired by this practical activity. You might as well use these methods to try melon seeds, candies, peanuts, etc. In fact, mathematics problems are closely related to life.
