In the first two years of junior high school mathematics, we need to learn Pythagorean theorem, square root, cube root, quadrilateral, triangle, function and so on. These contents are difficult in the whole junior middle school mathematics. If the whole junior high school is compared to a mountain, then the second grade mathematics is equivalent to going up the mountain. It plays a connecting role in the mathematics system of junior middle school for three years, and needs to learn the most knowledge points.

If you don't master mathematics in the second grade, it will be more difficult to improve mathematics after the third grade. But you can't give up because of difficulties. As long as you study step by step, you will get better results in the end.

First, pay attention to the foundation and don't blindly follow suit. The key to learning junior high school mathematics well is to lay a good foundation. Without a solid foundation, it is difficult to learn mathematics well. The foundation of junior high school mathematics is formulas and theorems. Remember commonly used formulas, understand the source and derivation process of formulas, and then strengthen the understanding and memory of formulas through practice.

Second, grasp the key points and break the difficult points. Learning mathematics can't be done with eyebrows and beards, we should distinguish between primary and secondary, and grasp the key points. When a teacher talks about knowledge points, he will definitely point out which ones are the key points. Therefore, we should listen carefully in class. In the process of listening, we need to use different symbols to mark which are important and which are secondary. Important knowledge points must be memorized and mastered.

Third, strengthen practice and sum up more. Practice is the key to learning mathematics well, and practice is the application of knowledge points. The mastery of mathematical formulas and theorems needs to be applied by constantly doing problems. Only through practice can we truly master what we have learned. In the process of practice, we should also record the key questions and important knowledge points so that we can see them at a glance when reviewing after class.
