Our life is inseparable from mathematics, such as the weight of food, the year, month and day on the calendar, and some mathematical equations are all related to mathematics. The following are the contents and pictures I shared with you. Welcome to read!

Chen Jingrun is a famous mathematician, who made great contributions to overcoming Goldbach's conjecture and founded the famous? Chen Theorem? So many people affectionately call him? The prince of mathematics? . But who would have thought that his achievement originated from a story?
From 65438 to 0937, diligent Chen Jingrun was admitted to Huaying College in Fuzhou. One day, Teacher Shen Yuan told us a story in a math class. A Frenchman discovered an interesting phenomenon 200 years ago: 6=3+3, 8=5+3, 10=5+5, 12=5+7, 28=5+23,100 =/kloc-. Every even number greater than 4 can be expressed as the sum of two odd numbers. Because this conclusion has not been proved, it is still a guess. Euler said: Although I can't prove it, I am sure this conclusion is correct.

From then on, Chen Jingrun became interested in this wonderful question. In his spare time, he likes going to the library. He not only read the counseling books in middle schools, but also eagerly read the textbooks of mathematics and physics courses in these universities.
Interest is the first teacher. It is such a mathematical story that aroused Chen Jingrun's interest and his diligence and made him a great mathematician.

The role of mathematics:
Learning mathematics should be used in real life. Mathematics is used by people to solve practical problems. In fact, there will be math problems in life. For example, when you go shopping, you will naturally use addition and subtraction, and you always have to draw pictures when you build a house. There are countless problems like this, and this knowledge comes from life and is finally summed up as mathematical knowledge, which solves more practical problems.
I once saw a report that a professor asked a group of international students: How many times will the minute hand and the hour hand overlap between 12 and 1? The students all took off their watches from their wrists and began to set their hands. When the professor tells the same question to the students in China, the students will use mathematical formulas to make calculations. The commentary said that it can be seen that China students' mathematical knowledge is transferred from books to their brains, so they can't use it flexibly. They seldom think of learning and mastering mathematics knowledge in real life.
From then on, I began to consciously connect mathematics with daily life. Once, my mother baked a cake, and two cakes could be put in the pot. I thought, isn't this a math problem? It takes two minutes to bake a cake, one minute in front and one minute in the back. At most, two cakes are put in the pot at the same time. How many minutes does it take to bake three cakes at most? I thought about it and came to the conclusion that it takes 3 minutes: first, put the first cake and the second cake into the pot at the same time, 1 minute later, take out the second cake, put the third cake and turn the first cake over; Bake again 1 min, so that the first cake is ready. Take it out. Then put the reverse side of the second cake on it, and turn the third cake upside down at the same time, so it will be all done in 3 minutes.
I told my mother about this idea, and she said, actually, it won't be so coincidental. There must be an error, but the algorithm is correct. It seems that we must apply what we have learned in order to make mathematics serve our lives better.
Mathematics should be studied in life. Some people say that the knowledge in books has little to do with reality now. This shows that their knowledge transfer ability has not been fully exercised. It is precisely because learning cannot be well understood and applied in daily life that many people do not attach importance to mathematics. I hope that students can learn mathematics in their lives and use mathematics in their lives. Mathematics is inseparable from life. If they study thoroughly, they will naturally find that mathematics is actually very useful.
