Supermarket Experience Mathematics Story 400 Words

Seven mathematical stories in "One" life, no less than 400 words,

This afternoon, my mother and I went shopping in the supermarket.

When we finished buying what we needed, we were about to leave. I saw sausages on the shelf, so I asked my mother to buy some sausages, and my mother agreed. But just after a few steps, I saw a package with the same brand and weight on the shelf, which contained 10 pieces at 4.30 yuan each. Do you want to buy a pack or a slice? I hesitated. Suddenly, my mind turned and I understood. Just compare and see which one is cost-effective. So I started to calculate: if I buy 10 pieces in retail, each piece costs 40 cents, 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 the process of my calculation, and my mother praised me for my love of brains. Also, I saw a puzzling math problem tonight. The topic is: 37 students want to cross the river. There is an empty boat at the ferry that can only take five people. How many times must they cross the river with this boat at least?

Careless people often ignore the "empty boat", that is, forget to have a gondola, so they can only take four people at a time. In this way, 37 people subtract one rowing classmate, leaving 36 students, 36 divided by 4 equals 9, and the classmate who worked as a boatman on the other side for the last time also landed 4, so it takes at least 9 trips.

Mathematics in life

It is sunny today. I go shopping in the supermarket. I saw a lot of things as soon as I entered. So I tried my best to go shopping, and soon my basket was full, so I asked my father, "Can you count the things here?" Dad touched his head. Who can work all this out at once? I said I could. I soon got tired of counting heads. Dad thought of a good way to find the cashier and ask him to help us.

I went to the cashier and said to my aunt, "can you help me calculate?" It is too difficult for us to calculate with our mouths. Please help us find out. After a while, I repeatedly praised and said, "Good, that's amazing. I asked my aunt how you did it. My aunt said, "It's not difficult for me to do such a small thing. I count by mobile phone. I said I was stupid. I didn't expect this. We packed our things and left. I've always wondered why my aunt knew all this. I don't know how my aunt came up with this and I didn't.

When I got home, I realized that there is mathematics in life, just like what happened today, there are things about mathematics. For example, many things can't be calculated clearly, so you can use a calculator. If you don't have a calculator, you can also use something like a mobile phone to calculate these numbers. Isn't this a solution? Solving everything in mathematics depends on the brain.

Therefore, life is inseparable from mathematics. When you encounter difficulties in mathematical calculation, use your brain to find a way.

"Three" mathematical fairy tales (about 400 words) are urgent! Urgent! Urgent! Going to school soon, I want to learn from it.

In the mysterious kingdom of mathematics, two "secondary numbers", namely "0" of the fat man and "1" of the thin man, often argue endlessly about who is important. Look! Today, these two little enemies meet in a narrow way, and they have launched another war of words.

The thin man "1" spoke first: "Hum! Fat' 0', what's so great about you? Just like 100, what's the use of you two being fat without my thin'1'?"

Fat man "0" is not convinced: "Don't be overbearing in front of me. Think about it. Without me, where are you going to find other numbers 100? "

"hey!" "1" is not to be outdone. "If you are arrogant again, you are nothing. Look! 1+0' is not equal to myself. What's your use? "

"Let's go! The result of'1× 0' is not me, and your'1'is also useless! " "0" is tit for tat.

"You ..." "1"paused and improvised. "Anyway, your' 0' doesn't mean anything!"

"This is your lack of knowledge." "0" said unhurriedly, "You see, in daily life, the temperature is 0 degrees. Is there no temperature? For another example, without my starting point on the ruler, how can there be'1'?"

"No matter how you compare, you can only do the middle number or mantissa, such as 1037, 1307, and you can never lead." 1 "said confidently. Hearing this, "0" said more confidently: "This may be, for example, 0. 1. What can you do without my" 0 "to occupy it?"

Seeing that the fat man "0" and the thin man "1" both blushed, no one would let anyone, and other people watching were very anxious. At this time, "9" had a brainwave and made a gesture of pause: "You two stop arguing. Look at you, which size is bigger than me? " "This ..." The fat man "0" and the thin man "1" were speechless. At this time, "9" said calmly: "1" and "0". In fact, as long as you stand together, aren't you older than me? "1" and "0" looked at each other, and it took a long time to scratch their heads and laugh. " That's right! The power of unity is the most important! ""No.9 "said earnestly.

The story of mathematician gauss when he was a child

From one to one hundred

Gauss has many interesting stories, and the first-hand information of these stories often comes from Gauss himself, because he always likes to talk about his childhood in his later years. We may doubt the truth of these stories, but many people have confirmed what he said.

Gauss's father works as a foreman in a tile factory. He always pays his workers every Saturday. When Gauss was three years old in the summer, when he was about to get paid, Little Gauss stood up and said, "Dad, you are mistaken." Then he said another number. It turned out that three-year-old Gauss was lying on the floor, secretly following his father to calculate who to pay. The results of recalculation proved that little Gauss was right, which made the adults standing there dumbfounded.

Gauss often joked that he had learned to calculate before he learned to speak, and often said that he learned to read by himself only after consulting adults about the pronunciation of letters.

At the age of seven, Goss entered St. Catherine's Primary School. When I was about ten years old, my teacher had a difficult problem in arithmetic class: "Write down the integers from 1 to 100 and add them up! Whenever there is an exam, they have this habit: the first person who finishes it puts the slate face down on the teacher's desk, and the second person puts the slate on the first slate, thus falling one by one. Of course, this question is not difficult for people who have studied arithmetic progression, but these children are just beginning to learn arithmetic! The teacher thinks he can have a rest. But he was wrong, because in less than a few seconds, Gauss had put the slate on the lecture table and said, "Here's the answer! Other students added up the numbers one by one, sweating on their foreheads, but Gauss sat quietly, ignoring the contemptuous and suspicious eyes cast by the teacher. After the exam, the teacher checked the slate one by one. Most of them were wrong, so 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 taken aback, and Gauss explained how he found the answer:1+100 =1,2+99 =10/,3+98 =/kloc-. A * * * has 50 pairs, and the sum is 10 1, so the answer is 50 × 10 1 = 5050. It can be seen that Gauss found the symmetry of arithmetic progression, and then put the numbers together in pairs, just like the general arithmetic progression summation process.

"Wu" gave me several compositions about mathematics in life, no less than 400 words.

In daily life, everything is inseparable from mathematics, which shows how close mathematics is to us.

For example, mom goes to buy fruits and vegetables, goes to the publishing house to reply to the manuscript ... and so on, all of which need math. 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. I was thirsty on the road, so my father had to buy mineral water from the nearby grocery store. There is a rule in the grocery store: if you buy three bottles of mineral water, you can get a bottle of mineral water, and the price of a bottle of mineral water is 1 yuan. When my father saw it, he took out 10 yuan and gave it to the grocery store owner, saying, "The boss bought 10 bottle of water." When I got the water, I drank it hungrily, and soon I drank two bottles. Before I came to my senses, there were several empty bottles. Dad asked me, "Lingling,1how many bottles of mineral water can 0 yuan exchange?" I think: I drank 10 bottle of water, 9 empty bottles were replaced with 3 bottles of mineral water, 3 empty bottles were replaced with 1 bottle of mineral water ... and there were two empty bottles left. I happily said to my father, "Dad, I have worked it out. Yes 14 bottle of mineral water, and there are 2 empty bottles left. " Dad smiled and said, "Think again!" I said thoughtfully, "We can borrow another empty bottle from the grocery store owner and return it to the boss after drinking it. Oh! We can drink 15 bottles of mineral water. " Dad nodded in praise.

Mathematics is to use it flexibly and integrate theory with practice. Only by mastering the knowledge of mathematics can mathematics serve us better. So we should learn mathematics well and make mathematics a good helper in our study and life.

Lu is a mathematician's short story with 400 words.

When Hua was in primary school, when a teacher introduced the school to a new teacher, he said that the students in this school were all poor children and most of them were idiots ... This deeply hurt Hua's heart and he was determined to repay the teacher with excellent results.

One day, the math teacher gave us an interesting question: "I don't know how many things there are." Two of the three plots remain, three of the five plots remain, and two of the seven plots remain. How many things are there? "

The whole class looked at each other, unable to answer. Only Hua stood up and said, "Teacher, I know it is' 23'." The whole class was shocked and the teacher nodded in praise. From then on, he fell in love with math class.

When he was studying, his father's shop business was getting worse and worse, so he had to drop out of school to look at the counter. He began to teach himself, using an algebra book, a geometry book and a calculus book, with only 50 pages left. I don't have time during the day, and I keep a small oil lamp to calculate repeatedly at night. His father called him a "bookworm" and forced him to burn books several times, but his neighbors advised him to do business well.

Unfortunately, he suffered from terrible typhoid fever again, and the doctor shook his head and sighed, asking his family to prepare a "funeral" for him. He challenged death, struggled to work in the field, and his left leg was disabled. Undaunted, he exercised with crutches and endured pain. Having practiced enough, he went to a middle school to fetch water and sharpen pencils for the teacher. Even so, he didn't give up self-study.

Soon after working in middle school, he began to send mathematical papers to newspapers and magazines, and he never gave up after being rejected many times. Later, he published the article "Why can't the solution of Su Jiaju's algebraic quintic equation be established?", which was appreciated by Xiong Qinglai, a master of mathematics, and was soon introduced to Tsinghua campus.

"Ba" Mathematical Story about Shopping

Count soybeans

Today's math copying class is a practical activity. We were divided into groups of eight people. Then, the members of each group work out how many soybeans there are in 1 kg. According to the estimation method introduced in the book, it seems not difficult, but it is necessary to be careful to minimize the error.

I suggested that the amount of cups used by our group would be more accurate, but we couldn't find any cups. Later, our group chose the method of hand grasping. Team member Luo Guangyuan is responsible for catching. Oh, dear! Luo Guangyuan's little hands are quite big! One fishing 180, 30 consecutive fishing, just caught 1 kg of soybeans. Finally, it's done. 30 180 equals 5400. So I know there are about 5400 1 thousand soybeans.

This practical activity inspired me. I might as well try melon seeds, sweets, peanuts and so on in these ways. In fact, math problems are closely related to life.
