Mathematics is a step-by-step knowledge structure, closely linked and interlocking, so poor junior high school will directly affect the continuing study of senior high school. Now, we should pay close attention to its lack? Leak, lay a good foundation.

Many students reflect that the concepts of set and mapping are difficult to understand and feel far away from life. Indeed, there are significant differences in mathematics language between junior high school and senior high school. Junior high school mathematics is mainly expressed in vivid and popular language. Mathematics in senior one involves abstract set language, logical operation language, functional language, space solid geometry and so on.

Mathematics is applied.

In many different fields, including science, engineering, medicine and economics. The application of mathematics in these fields is generally called applied mathematics, which sometimes arouses new mathematical discoveries and promotes the development of new mathematical disciplines. Mathematicians also study pure mathematics, that is, mathematics itself, without any practical application. Although a lot of work started from the study of pure mathematics, it may find a suitable application later.
