Mathematical modeling is a method to abstract practical problems into mathematical models and predict and solve practical problems by solving the models. It plays a vital role in solving practical problems.

First of all, mathematical modeling can help us better understand practical problems. By abstracting and modeling the actual problem, we can understand the essence of the problem more deeply and find out the key points and difficulties of the problem.

Secondly, mathematical modeling can improve our efficiency in solving problems. Through the mathematical model, we can quickly analyze and calculate the problem and get the solution of the problem, thus saving a lot of time and energy.

Thirdly, mathematical modeling can improve the accuracy of our problem solving. Mathematical models can accurately describe various factors and relationships of problems. By solving the model, accurate results can be obtained and human error can be avoided.

In addition, mathematical modeling can also help us predict the future. By modeling the historical data, we can predict the future development trend and provide the basis for decision-making.

Finally, mathematical modeling can also promote the development of scientific research. Many scientific problems can be solved by mathematical modeling, which can not only promote the development of scientific theory, but also promote the progress of science and technology.

Generally speaking, mathematical modeling plays an important role in solving practical problems, which can help us better understand problems, improve the efficiency and accuracy of solving problems, predict the future and promote the development of scientific research.
