Mathematics learning skills

The most taboo in learning mathematics is that there is only one way to solve problems, especially under the premise of changeable examination methods, so it is difficult for such a single learning thinking to cope with high-intensity high school study life.

In fact, with the increase of learning difficulty, we must have flexible learning ideas, so it is particularly important to learn to push forward and backward the learning content and develop efficient problem-solving ideas at this time, which is particularly important for improving math scores.

According to different angles, there are often completely different ways of solving problems. Therefore, when studying at ordinary times, we should start to cultivate both positive and negative problem-solving ideas. For example, if there are different solutions to the same problem, it is necessary to read more books, study more, recite more, and learn more from peacetime.
