The sixty-fourth chapter of Tao Te Ching says: "Hemu is born in a millimeter; The nine-story platform starts from the foundation soil; A journey of a thousand miles begins with a single step. Learning mathematics is like a journey of a thousand miles, and learning mathematics well is like the first step of a journey of a thousand miles.
The first step-hope. Where is the puzzle of mathematics? After seeing that confusion, sort out all the knowledge points and common mistakes in order to find the law.
The second step-smell. After knowing where you are prone to lose points, you can solve such problems in new ways when you encounter such problems again in other places.
Three aspects of learning-problems. When you walk, you must learn from others and ask bravely.
The last but also the most important step-cutting. I suggest you find yourself an excellent tutor when you encounter bottlenecks in your study.
Ⅱ Hua 400-word composition Rubik's cube
Today, all the teachers and students in our school came to the Workers' Theatre to watch a children's play. The name of this children's play is Youth China.
The main content of the story is that Hua got a magazine, and there was a paper in the magazine, written by Professor Su, called "Solving Algebraic quintic Equation". He studied the paper Sleepless Night and found that Professor Su made a mistake in the paper. But at this moment, the accident happened. Hua's mother passed away. He lost the consciousness of one leg because of illness, but Mr. Zhao, who knows China best, doesn't trust him. In an instant, Hua had nothing. However, after all, many things happen. Hua survived many difficulties, finally published a paper, went to Tsinghua University as a professor, won everyone's recognition and admiration, and became a bright star in the field of mathematics.
After watching this drama, I can't be calm for a long time. Hua, I want to tell you that I really admire your spirit of believing in yourself, resisting pressure, pursuing truth and daring to challenge authority. Every detail you put in is worth learning. Every time I think of meeting some difficulties and trying to back down, I feel extremely ashamed. Flowers, you let me know how to persist and how to face difficulties. I will follow your example, study hard and become a better junior high school student.
When we grew up happily and healthily under the wings of our parents, Hua endured the pain of losing her mother and legs, broke through one difficulty after another with tenacious perseverance and finally reached the peak of her life. Regardless of material difficulties or mental pressure, Hua has always adhered to his belief: learning mathematics, he loves mathematics, and he wants to conquer mathematics!
Thinking of this, I deeply feel that we are so different from Hua. Why can he succeed and we can't? His tireless research is what we should learn, and his tenacious perseverance is what we admire ... I think there are still many spirits in China worth learning! Hua, you are amazing!
Ⅲ Mathematicians' Short Stories 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.

The growth process of China
19101012 was born in Jintan District, Changzhou City, Jiangsu Province. When he was young, he liked to think. Because he was too absorbed in thinking, he was often nicknamed "Luo bookworm" by his companions. 1922, 12 years old, after graduating from Renmai Primary School in the county, entered Jintan County Junior High School. Teacher Wang Weike discovered his mathematical talent and tried his best to cultivate it.
1925, studied in Shanghai China Vocational School after graduating from junior high school. I dropped out of school because I couldn't afford the tuition and went home to help my father manage the grocery store, so I only had a junior high school diploma all my life. Since then, he has taught himself all the math courses in high school and junior college in five years.
/kloc-in the autumn of 0/927, he married Wu. /kloc-in the winter of 0/929, he was unfortunately infected with typhoid fever, leaving his left leg disabled for life. He had to walk on crutches. From 65438 to 0929, Hua was employed as a clerk in Jintan Middle School and began to publish papers in Shanghai Science and other magazines.

Inspiration from Mathematicians' Stories Selected 400-word Compositions
On Sunday morning, it was sunny and cloudless in Wan Li. I had a good time. At this time, my mother came over and told me that this is a raw embroidered kitchen knife. Please sharpen it. I said yes directly.
As the saying goes, it is easier to see things than to do them. I think it's true. I have just sharpened my knife for a while, and my hands are tired and I am so angry that I can't laugh or cry. I want to give up honing, so I muddle along and get scolded by my mother at most. But looking at the rusty blade, it seems to be laughing at me smugly: really retarded, give up halfway.
At this time, the story told by the teacher in class clearly emerged in my mind. It is said that Li Bai often played truant when he was a child. Once, on the way to play truant, Li Bai saw an old lady grinding an iron pestle by the river. Curiosity made him move forward involuntarily. Li Bai asked the old lady: Why are you looking for trouble and grinding the iron pestle? Isn't this a waste of effort? The old lady said earnestly, son, I'm not looking for trouble. I am grinding the embroidery needle with this pestle. Li Bai couldn't help laughing. He also said to the old lady: this is impossible. The pestle is so thick and the embroidery needle is so small. When will it be ground? The old lady solemnly said: As long as you have patience and perseverance, you can do great things. Rome wasn't built in a day. Li Bai felt ashamed because he had no patience for anything before. After a while, he worked hard every day, went to Qiu Lai in the spring, and finally became a famous poet in the Tang Dynasty.
I think the old lady has a persistent spirit. Why can't I? So, I settled down and began to sharpen my knife. I put the kitchen knife on the grindstone and ground it with all my strength. The grindstone rustled like a silkworm eating mulberry leaves. I grinded hard again, and the sound of rustling sand became louder, as if the spring rain were moistening the earth. After a while, the blade became extremely sharp and sparkled in the sun. Looking at the sharp knife edge, it seems to be sincerely praising me: the young artist can really bear hardships and stand hard work.
Through this incident, I understand: nothing is difficult in the world, nothing is impossible to a willing mind. If you want to see the truth, pay close attention everywhere.
Ⅳ My dream composition is 400 words.
A paper plane flew past me gently. Oh, that small and light posture, that clean and dust-free flight, how familiar. Is it the one in the hand of my brother when I was a child? Suddenly, my sight has been quietly taken away by it, and my childhood memories are hanging in the treetops.
The sky is clear and holy, like a light blue silk handkerchief; Clouds, white and flawless clouds, like veils; The wind, carefree wind, set off bursts of golden wheat waves and shed brilliant hope. A little boy stood on the ridge of the field and released his paper plane. The plane flew downwind, and he cheered and waved his hands vigorously. This is my childhood brother. Folding planes and flying them were the greatest pleasures of his childhood. Although he didn't express his ambition to be a pilot or build a plane, he folded the paper plane again and again. He looked up at his paper plane flying in the sky and tried to smile with his eyes open. Brother must have a dream hidden in his heart-eager to fly and weave an ideal dream in the blue sky.
In this way, my brother folded up his childhood dream with his tender little hand. However, there is never a pair of gentle big hands to gently soothe his innocent dreams. Once, my brother excitedly picked up a paper plane that had just been folded and ran into the house. "Mom, this plane can fly very high. Come on, let me show you! . "He wants to drag his mother out. "Don't be ridiculous, I'm busy." Mother shook off his hand. "You are in elementary school, still playing with these useless planes. Go and do your homework! " ""It's already over. " The smile on my brother's face suddenly disappeared. He looked up at his unhappy mother and turned and walked away step by step. Several times, he looked at the paper plane in his hand and stopped to look back at his mother. His eyes are full of grievances and losses. What a nice paper plane. My mother will like it at first glance, but she didn't watch it just now.
This story has been repeated many times. Every time my brother runs happily, he comes back depressed. Gradually, my brother became silent. He often sits alone on the ridge of the field, sometimes looking up, watching his paper plane swim, glide and fly over the field; Sometimes he lowers his head, deep in thought, thinking about the doubts he has been unable to solve. He folded fewer planes, and finally one day, all his planes were left behind. I asked him why, but he just shook his head. Is it because you have really grown up? I don't know. I only know that no one has carefully appreciated his paper plane, and no one has touched his head and said, "Son, you are really good." No one tried to knock on his heart and listen to him. ...
Suddenly, I remembered the paper plane in front of me and hurried to look around. I saw it stuck firmly on a branch and couldn't fly, but the sun shone on it. It was so beautiful ... I had a dream.
I have a dream, deeply rooted in my heart. I want to be a scientist when I grow up.
Although I don't have extraordinary intelligence, rigorous thinking and particularly accurate judgment, I won't give up my efforts. Although this dream is far away from me, I will not stop pursuing it. Although there will be many setbacks and countless hardships in the process of realizing my dream, I will not be discouraged. Because I believe that only through training in hell,
In order to cultivate the power of creation; Only bloody fingers can pop up the swan song of the world; Only by experiencing difficulties and setbacks can we realize our dreams.
In the past, whenever I saw the outstanding achievements of scientists, I always felt envy and admiration. It is they who promote the development of society; It is they who have improved people's living standards; It is they who have won a brand-new tomorrow for the development of the motherland.
Therefore, I want to be a scientist, a person who has contributed to the country, and a pillar of this country. Whenever I see people who waste time, I feel sorry for them; Whenever I see frustrated people, I feel sorry for them; Whenever I see people who don't do their job well, I feel indignant. Because they can't see their own value and have no dreams. This life is meaningless.
And I, at least, have a dream and a goal. With this dream, I will always work hard and never give up. With this dream, you will master your own life direction and will never lose your way again. With this dream, it is like a bright light, illuminating my way forward. Until the pinnacle of victory.
I will work hard for this dream. I also hope that everyone can forge ahead towards their dreams and find their own tomorrow.
ⅵ Enlightenment from mathematician's story; Selected 400-word composition
Today, I do my homework at home. After writing, my mother told me a story about Liu Xi educating children.
Liu Xi is a stepmother. She treats her biological son and her non-biological son equally in education. She was very strict with her two sons, and eventually they both became talents.
She told her eldest son to go to school, but instead of going to school, she said, "I'm going to raise pigs" and lived with the servants. After a long time, he has had enough. Realizing that school is much better than raising pigs, he regretted not listening to his mother and said to her, "I don't want to raise pigs, I want to go to school." His mother made him feel that the school was good, and later his son was elected as the county magistrate. He also likes to spend money. One day, Liu Xi gave his second son thirty taels of silver and a lot of fake money. In the end, he spent all the thirty taels of silver because there was still so much money. But when he gave fake money to others, he was recognized as fake money and put in prison. This was originally because Liu Xi deliberately sent his son to prison to learn a lesson, just like the way he educated his eldest son. After getting out of prison, the second son learned a lot. He began to study hard and eventually became a successful man.
After listening to this story, I know that I should study hard since I was a child.
ⅶ Why should I learn to write 400 words in the fourth grade of primary school? Homework help.
Study for the prosperity of China! "
The motto on the corner of the table suddenly came into view, and immediately a stream of heat flowed all over the body, so * * * struggled vigorously.
That year, when the old headmaster asked Premier Zhou Enlai why he was studying, his groundbreaking words "Studying for the Rise of China" resounded throughout the century.
Now, why should I study? I asked myself this question. China has risen.
My eyes are hard, so I wrote this sentence-"study for the prosperity of China!"
Yes, our motherland is only a developing country, and we will be beaten if we lag behind, so our country should be rich and strong! I want to work hard for the future prosperity of my motherland! Since then, this sentence has become my motto on the corner of the table.
I learned about the modern history of China, watched historical films, brutal scenes, humiliation of being bullied, bloody lessons ... I was really angry and hated. I clenched my fists and gnashed my teeth, thinking that this kind of revenge is not a gentleman! Suddenly I hung my head like a deflated balloon-I was really angry, but what could I do?
A word flashed through my mind-"study for the prosperity of China"
Oh, great! I will work hard, study hard and study for the prosperity of China!
So I suddenly straightened up and threw myself into my study.
In the graduating class of grade three, learning is really heavy, and it is impossible to be neither bitter nor tired. Time is pressing, and there are a lot of big things and small things.
I failed the exam again; How to learn so confused; Why failed again ... I'm very upset, I just feel so tired and want to collapse. However, when I looked down, I caught a glimpse of the sentence-"study for the prosperity of China!" " Stunned, as if thinking of something.
Yes! China needs to serve its country. I love my motherland, I want to serve my motherland and dedicate myself to it! And how can a terminally ill person become a great success? So I will be positive and keep working hard!
When thinking like this, the fighting spirit suddenly broke out.
One by one reads "study for the prosperity of China!" I put sticky notes all over the room. Seeing each other all the time makes me start practicing crazily, making me race against time. I know that my efforts will not be in vain, and my diligence will lead me to the shortcut to success.
When the wind blows, casual stickers are singing and dancing. It cheered me up.
One day, the teacher asked me, "Why do you study?"
Looking at her, I smiled: "study for the prosperity of China!" " "
Ⅷ math problem! ! !
A * * * borrowed 1000 yuan, used up 970 yuan, and left 30 yuan 10 yuan for his father, 10 yuan for his mother, that is, 970+/kloc-0+65438 = 990, and kept it for himself 10 yuan.
In fact, this sentence is wrong: "I have 10 yuan left, and I owe my father 490 yuan and my mother 490 yuan". 970 divided by 2 equals 485, plus 10 yuan, I owe 495 yuan, not 490 yuan.
Or how about this: I bought a pair of leather shoes and spent 970 yuan. I paid back 20 yuan, 970+20=990 (not 490 respectively, but 990 respectively), and then added my own 10, which was equal to 1000. This kind of problem belongs to a kind of thinking illusion, and it will come out in the future.

ⅸ How to write a 400-word story composition?
Book Association
Gorky said: "Books are the spiritual wealth of human beings and the ladder of human progress". In my bookcase, there are all kinds of books I grew up with. Every book has an extraordinary experience, which I worked hard to get, especially the interesting math, which is my favorite book and the book I got after overcoming the biggest difficulties.
I went to a friend's house to play in the summer vacation and was immediately attracted by his "Interesting Mathematics": this book tells interesting stories and makes people unconsciously learn various methods to solve problems. I was so fascinated by this book that I made up my mind to buy it. I was a little worried when I learned that this book cost forty dollars for half a year. Will my mother buy it for me? This is not cheap! However, the love of books prevailed. I crustily skin of head and mother tentatively discussed buying books. My mother was quite supportive, but she said, "You have to buy this book yourself. Ok, starting from today, the first place is 20 yuan, the second place is 10 yuan, and the third place is 5 yuan. Work hard. " I'm glad to hear that. Fortunately, I met a wise mother. I have been studying hard since that day. Whenever I am tired, I have a strong desire to buy books. Finally, I got two firsts and one second, and I got 50 yuan. After getting the money, I couldn't wait to run to the bookstore and finally bought the "interesting math" I dreamed of. Sure enough, I finally got it.
This is a story between me and this book. Now I still insist on subscribing to every issue of interesting mathematics, and this book will always grow with me.
