Characteristics of "Mathematics Curriculum for Technical Secondary School (Volume/Kloc-0)" (2nd Edition): Pay attention to the connection with full-time junior high school mathematics textbooks. Adopt national standard mathematical symbols. Take into account the needs of engineering, finance and agriculture, and choose the content according to the specialty. Generally speaking, asking questions from practical problems paves the way for the introduction of theory, which not only embodies the principle that theory comes from practice, but also receives the effect of natural transition.

It effectively strengthens the application. In theory, it is based on sufficiency to avoid complicated theoretical derivation, and many theorems, formulas and methods are only explained or summarized intuitively to avoid abstract proof.

In all chapters directly related to practice, special application parts have been added to strengthen the application of theory. At the same time, it also enriches many examples and exercises linked with practice.
