Expand one's knowledge

Reciprocal is a mathematical term, and pinyin is dào shù. Mathematically, it means that the product of a number x multiplied by it is 1, and it is recorded as1/X. The process is "multiplication inverse", and all numbers except 0 have reciprocal. The numerator and denominator are inverted, the number whose product is 1 is reciprocal, and 0 has no reciprocal.

learn math well

Look at the textbook and find out the principle.

Some students think that the content in the textbook is too simple. After reading it several times, they put it down and ran to brush the questions and do their homework. However, when the principle is not clear, it is likely to make more mistakes, which will not only undermine self-confidence, but also fail to understand the problem, which is useless.

There are also some students who choose to learn by rote because they don't know much about textbooks. Principle formula of mechanical memory. If you encounter topic deformation or synthesize several principles, you will usually find that you still can't do it or can't use it flexibly.

Step by step, focusing on understanding.

Sometimes when you encounter a particularly difficult chapter, you will feel afraid of difficulties and choose to give up. Doing so will bring some risks and make math learning out of touch. Because the content of mathematics is coherent, the last knowledge point may be the next foundation. If you choose to let go of this place that you don't understand, you may not be able to keep up with the content behind, so problems will accumulate.

Practice a lot, brush the questions constantly, brush the questions constantly.

Can you think about how many exercises you have done? How many math exercise books have you made? On one occasion, a Tsinghua schoolmaster recalled his middle school life and said, "I remember that mathematics was a relatively weak subject at that time. In order to catch up with the progress, I spent a summer vacation doing about 50 sets of math test papers. At that time, I had time to brush questions every day.

Later, mathematics suddenly "enlightened" and its grades soared. After that, in addition to the questions assigned by the teacher, I also bought three sets of math tutoring exercises. "Although this student's experience is different for you, it is difficult to improve mathematics without a lot of practice. Practice makes perfect. Only by doing a lot of exercises, reading more questions and doing them smoothly can we accumulate problem-solving skills.

Do the questions carefully and clarify the principles.

The last point mentioned many questions, but if the exam is near and time is limited, you must learn to do well. The first step is to "choose the right questions" and the second step is "investigation principles". Choosing a good question is to choose an exercise that suits your learning level and can stimulate your thinking. I suggest you consult your math teacher or compare yourself and choose an exercise book for typesetting and editing.
