As students, we are no strangers to mathematics, from addition, subtraction, multiplication and division in primary school to various plane geometries in junior high school to various functions in senior high school, and so on. Mathematics is particularly rigorous and logic is very advanced. Mathematics is different from other subjects. It can not only solve the abstract problems of mathematics itself, but also deduce the solutions to countless practical problems. Mathematical reasoning is not only useful in school, but also has unparalleled value charm in the future. For mathematics, I think I need to spend my whole life exploring and exploring. Especially the complex relationship between plane graphics, is that countless people can't learn for a long time.
