Both depend on mathematics, and they are very abstruse pure mathematics.
Mathematics and applied mathematics emphasize the analysis of problems with pure mathematics, and study economics and computers. Representative disciplines, such as operational research, mathematical modeling, mathematical experiments, etc. , are using mathematical knowledge to solve problems.
However, its application is not as clear as that of computers and economics. In fact, you need to learn theory to guide the application of computer and economics, not the application itself. Therefore, applied mathematics should be regarded as the research of applied mathematics, not the application of mathematics.
This solution made me go to college for four years by mistake. At present, the major that is difficult to find employment is 10, and this major has one!
Computational mathematics focuses more on computers. In fact, it is the study of mathematics and programs. It is not for you to calculate anything, but for you to study a theory, a program at that time, and for people who don't know much about mathematics and computers to complete the calculations they need.
Don't choose these two majors without academic research!
