Theoretically speaking, learning mathematics is to cultivate students' rational thinking ability. Mathematics learning is to train and cultivate students' habit of thinking seriously by analyzing numbers, figures and linearity, and then observing, guessing, drawing conclusions and demonstrating, so as to further enhance students' ability to look at problems comprehensively and objectively and avoid doing things rashly.
Learning mathematics can also cultivate students' autonomy, cooperation and inquiry ability. In life, some things can be solved with the help of other people's experience, but more problems need to be solved by exploring their own experience and discovering new laws.
Many mathematical problems are deduced by students' hands-on, observation and application of what they have learned, thus obtaining new conclusions and formulas. For example, learning the sum of interior angles of polygons is to divide polygons into triangles by using the sum of interior angles of triangles, thus summarizing the formula of interior angles of polygons.
