Middle school mathematics in life
Some people say, "Mathematics is so profound that people are puzzled." But in my eyes, mathematics is at most a set of knotted ropes. You must untie one knot after another patiently, and one day you can untie all the knots. The most important thing in learning mathematics is to be good at thinking. If you compare mathematics to a lock, then thinking is the golden key to open it. You can not only collect honey, but also make honey. Mathematics is to use what you have learned to solve unknown problems. Learning mathematics requires perseverance, patience and perseverance. Like a well digger, he gives up when he is near the water source. All his previous work was in vain and failed to achieve his goal. It is also important to be careful when solving math problems. As long as there is a little negligence in calculation. It may lead to a total loss. Don't wait until you have done something wrong to regret it. There is no regret medicine in the world. Therefore, while studying mathematics, we should pay attention to cultivating our good thinking habits, learn to use them flexibly, and draw inferences from others to get twice the result with half the effort.
Live in a math middle school.
Mathematics is the key to solving life problems. Learning mathematics means learning to apply and learn to live. As long as we understand it carefully, we will find that mathematics is around us. For example, shopping will use digital operations; Children will use space geometry when building blocks; Building a house will use the fusion of graphics; Statistical knowledge will be used for voting and elections ... There are countless such problems, which shows that life and mathematics are inseparable, and the calculation of numbers is everywhere in life. Finance, shopping, size comparison, etc. , all use numerical calculation. It has brought far-reaching value to our life, not unusual.
In real life, we will see all kinds of patterns composed of regular polygons. For example, at home, in shops, in the central square, into hotels, restaurants and many other places, we will see tiles. They usually have different shapes and colors. Actually, there are some math problems. On the tiled floor or wall, adjacent tiles or tiles are evenly stuck together, and there is no gap on the whole floor or wall. From this, we get that. N polygons can be divided into (n-2) triangles, the sum of internal angles is (n-2)* 180 degrees, the degree of an internal angle is (n-2)* 180÷2 degrees, and the sum of external angles is 360 degrees. If (n)
Therefore, we can better serve and enrich our lives by accurately grasping the connotation of numbers and using the extension of numbers. At the same time, I also learned that "learning without thinking is useless, and thinking without learning is dangerous!"
In short, in the process of learning mathematics, we can acquire mathematical knowledge, and use what we have learned to solve problems and solve some practical problems in life. More importantly, we can exercise our ability to observe things, analyze and judge and innovate in the process of learning mathematics, which can help us walk better in life and benefit us for life.
