This semester, the teacher taught a new knowledge, that is, the multiplication and division of decimals. This knowledge helps me a lot! Last night, my mother went to buy oranges together. A kilo of oranges 1.8 yuan. My mother bought 4.5 kg and should pay 8. 1 yuan. But the clerk was careless and didn't know how to calculate it, so it became 9 yuan money. Fortunately, this semester, I used the knowledge of Protestantism, and after doing a calculation in my mind, I immediately corrected the salesman's mistake.
Not only did my aunt, the shop assistant, praise me for my cleverness and my ability to multiply and divide decimals in such a small city, but my mother also praised me for saving her 0.9 yuan on the way home, and the knowledge I learned can be applied in my life.
Yes! If you don't learn this math well, it's not only 0.9 yuan that will lose, but also hundreds, thousands or even hundreds of millions!
Chapter Two: About Mathematics
When you swim in the stormy waves of mathematics, can you ride the wind and waves? When you are struggling in the hard and painful real life, can you still love mathematics? When you are full of doubts about extremely simple questions, can you ask why? When you recite a difficult mathematical concept by heart, can you show it in your life? When you have questions about famous mathematical books, can you boldly question mathematics? Unfathomable and wonderful. If you don't understand, it will bother you; But once you fall into the bottomless pit of mathematics, you will be deeply attracted by its wonders. When a difficult problem is solved through your hard thinking, you will feel a sense of accomplishment and a wonderful feeling of being in heaven. Talking about the past and present, how many clever geniuses and buried talents mathematics has achieved: "Father of Mathematics"-Cyrus, "Prince of Mathematics"-Gauss, "Problem Seed"-Euler ... What great mathematicians they are. However, are their math careers smooth sailing? No, they all went through countless storms to see the beautiful rainbow! Hua, a self-taught mathematician, still loves mathematics and his pursuit when his left leg is paralyzed and his life is hopeless, and bravely questions the paper of the famous professor Su Jiaju. Without this, Hua would not be a great mathematician, let alone the pride of China. The greatness of Cyrus, the father of mathematics, is that he can not only explain the problem, but also add a scientific question mark. He is not superstitious and loves science. At the age of eight, the clever Gauss knew how to calculate 1+2+3+ ... N used by the ancient Greeks and China to calculate 1+2+3+ 100.
Why can he use this method to calculate, because he is willing to use his brain and loves to use it; Although Euler was a famous mathematician, he was not liked by his teachers at all when he was a child. He was a student expelled from school because he asked a question: How many stars are there in the sky? You know, it is impolite for God to ask such a question, and in Euler's time, God was sacred and inviolable, so he was fired. But it is precisely because of his good habit of asking questions that he became the youngest college student in accel University. A person, as long as he has the noble qualities of loving brains, mathematics and science. He can boldly question, embody mathematics in his life, actively ask why, never flinch when encountering problems and never give up, then he has taken the first step to become a great mathematician in the future! And I, as the future flower of the motherland and the hope of the nation, it is my bounden duty to learn math well, for the rise of China, for the bright future of China, and for myself! The ocean of mathematics, I am swimming, I want to raise the sail of my dream and ride the wind and waves in the ocean!
Chapter Three: About Mathematics
I am a lively and cheerful boy. I like abstruse mathematics. Mathematics has an attraction for me. As long as I see a math problem, I will concentrate on it without making a sound, as if I have come to this profound math kingdom. Some students say that mathematics is profound. I think it's because there are olympiad numbers in mathematics. Indeed, if you don't know anything about the Olympiad, you will be confused and think that mathematics is not fun at all; Of course, if you are interested in olympiad, you will have a belief that you must do it well and finish it in the process of calculation. That's how I overcame one Olympic math problem after another, and I got a sense of intimacy in mathematics.
I still remember that I participated in the Olympic Mathematical Contest in Grade One and Grade Two. In the competition, in the face of those Olympic math problems that I didn't do, although I was sweating, I still devoted myself to them as always. With my efforts, I won the third place every time, and my heart was as sweet as honey. But I still hope that one day I can win the first place in the competition.
I can't live without the Olympics. It is like my partner, and I will be in close contact with it for a period of time every day. Up to now, I have done all kinds of Olympic math problems, my ideas are getting wider and wider, and my interest in mathematics is getting stronger and stronger.
I want to be a mathematician when I grow up. This is me-a boy who loves mathematics deeply.
Chapter Four: About Mathematics
I have been studying mathematics for more than six years, and this road of learning is bumpy and full of difficulties.
I remember when I was in the third and fourth grades of primary school, my math score was not good, and it kept fluctuating around 80 points. Maybe I was afraid that math would have resistance to this subject. When I was in the sixth grade, faced with a severe graduation exam, I had to bite the bullet and study math seriously. Only then did I realize that mathematics was not as terrible as I thought. I just found out that mathematics is actually the most interesting subject of all. After entering middle school, I really discovered the magic of mathematics. It can bring us endless fun. Elementary school mathematics has learned a lot of knowledge: algebra, rational numbers, algebraic expressions, one-dimensional linear equations, binary linear equations ... In the process of learning, it is inevitable to encounter some setbacks, and there are countless regrets caused by carelessness. Those naughty elves take advantage of your little weakness or flaw to make you lose.
In mathematics, my biggest weakness is carelessness. Because of carelessness, many of my unit test scores are not ideal; It was because of carelessness that I missed the first place in the mid-term exam. It was because of carelessness that I failed in the competitions of various subjects ... Maybe many regrets caused by carelessness have disappeared in my mind. What bothers me most is that I can't completely get rid of carelessness. In this math final exam, I made another careless mistake, so-so, which caused my math score to be 6 points lower than the best score of that year. Although, I know that only by getting rid of this shortcoming can my math scores be significantly improved, so far I have not been able to completely get rid of this shortcoming.
I believe that it is not impossible to learn math well with my real strength. However, I don't know why, but I can still cope with studying math and doing homework in class. But when I pick up the math book after class, I always find it difficult to understand, especially geometry.
Chapter 5: About Mathematics
Mathematics is beautiful, and mathematical knowledge is infinite. The mathematical formula is wonderful and magical, and its application
