Useful, it can be used to preview new knowledge. I suggest you prepare a notebook and take notes. It's still helpful for my math score, which has improved by at least 1 points. Now every exam is around 9 (out of 1). I'm in Grade Two now, and this software is really good.

Ways to learn mathematics well:

1. Mathematics, like other disciplines, also has many conceptual things. The basis of learning mathematics well is to understand what the definition really means. For example, the meaning of square, cube and absolute value in mathematics.

2. We know that the square is the multiplication of two identical numbers, and of course the cube is the multiplication of three identical numbers, and the absolute value is the value greater than or equal to . Knowing the true meaning of the definition, we have taken the first step and laid a solid foundation for the following study.

3. Some people say that when you see the last question, you will have a big head, not that it is difficult to start. It's that you haven't learned to use it comprehensively. Short answers in mathematics can only be answered by using a lot of knowledge, not just one knowledge point.

4. So everyone must practice more and really learn the scattered knowledge points in mathematics. When you meet the last question again, you will really think of where to start. The reason why you can't do it is that there are still some knowledge points that you haven't learned and remembered firmly. Therefore, through my brief introduction, I believe that I will not be lazy about learning mathematics in the future.
