2. Mathematical modeling is often directly related to some engineering fields and practical problems. The basic idea is to abstract one or a series of mathematical conclusions based on mathematical theory and other knowledge, such as machinery, chemical engineering, civil engineering, etc. Mathematical modeling belongs to an applied mathematics. Learning this course requires us to learn how to reduce the actual problem analysis to a mathematical problem, and then solve it with appropriate mathematical methods.

3. Mathematical modeling is a mathematical thinking method, and it is a powerful mathematical means to describe and solve practical problems by using mathematical language and methods through abstraction and simplification.

4. In order to make the description more scientific, reasonable, objective and repeatable, people use a language that is generally regarded as strict to describe various phenomena, which is mathematics.

5. What is described in mathematical language is called mathematical model.
