2. Mastering the commonly used mathematical thinking methods to learn high school mathematics requires us to master it from the height of mathematical thinking methods. Mathematics thoughts that should be mastered in middle school mathematics learning include: set and correspondence thoughts, classified discussion thoughts, combination of numbers and shapes, movement thoughts, transformation thoughts and transformation thoughts. With mathematical thinking, we must master specific methods. In concrete methods, there are observation and experiment, association and analogy, comparison and classification, analysis and synthesis, induction and deduction, generality and particularity, finiteness and infinity, abstraction and generalization. When solving mathematical problems, we should also pay attention to solving the problem of thinking strategy, and often think about what angle to choose and what principles to follow.
