Mathematical modeling is the process of constructing mathematical model, that is, using mathematical language-formulas, symbols, charts and so on. To describe and describe a practical problem, and then through mathematical processing-calculation, iteration, etc. , get quantitative results for people to analyze, predict, make decisions and control. The so-called mathematical model is a mathematical structure that abstracts and simplifies some real worlds for a certain purpose. In short, a mathematical model is a part of describing the real world in mathematical terms.
