In addition to some knowledge, I also got some related methods to do the problem. Moreover, these problem-solving methods are of great help to my future study of mathematics, and some of my ideas during my study of mathematics have also been changed.
In addition, some shortcomings of self-taught mathematics are that I can't concentrate all the time in class, that is, I sometimes get distracted during class, which affects the students around me. This is a shortcoming that I need to correct. Next semester, I will keep good advantages, and I will actively find ways to improve some shortcomings.
So this can be used as a personal summary about mathematics.
