Mathematics is not taught, it is realized, it is lf-taught. Mathematics can't be en, it can be calculated. The most important thing in learning mathematics is the ability to solve problems. At the same time, we should listen carefully in class, do matching exercis after class, and learn to adapt to changes with invariance各有所长.
The simplest way to learn is to "comprehend", that is, to think hard and learn a mathematical concept. In addition to understanding what the concept means, you should also do some exercis. Many people don't reflect after they have problems, just don't think about why they are wrong? What caud this mistake, how can I avoid it next time, and how can I summarize it.
Seize the classroom. Science study focus on daily work, which is not suitable for sudden review. The most important part of daily study is 45 minutes in class. Listen attentively and think cloly with the teacher. High quality homework. When doing homework, sometimes repeat the same type of exercis, then we should consciously test the speed and accuracy, and be able to have a deeper thinking about this kind of questions when we finish each time.
To the wrong questions that can't be done: understand every step and think about why; For the wrong calculation, if this often happens, then you need to: change the calculation method and habits, such as learning to check and calculate twice to improve accuracy. The point is to think! The deeper you think, the more thorough you will learn, and you will achieve high results with a small number of questions. But this kind of thinking is not out of thin air, but bad on wrong questions. Learn from your mistakes and make up for your shortcomings. You will make fewer and fewer mistakes next time.

No matter how the former turns or walks askew, the one behind will do as it does, without exception. This is becau the first caterpillar spits a filament while walking, the cond caterpillar will follow the filament and spit a filament on it, and so on.

Today may be this one, tomorrow may be that one, there is no definite rule.
