Hello, I am also an undergraduate majoring in mathematics, two years older than you. According to my understanding of the department of mathematics, in fact, the advantages of the department of mathematics are great, at least I am not very worried about the subject of mathematics. In fact, the most important thing is to see what you want to do in the future. Don't just know which direction is good for employment and which direction is good for making money. You should add your hobbies before you think about it. If you like the study of mathematical theory and pay attention to the proof of logic, of course, basic mathematics is preferred. If you like development and feel a sense of accomplishment in applying mathematical knowledge to military affairs and fields, then apply mathematics. If you like the softness of the width and depth of economics and mathematics, then you choose operations research. As for probability statistics, don't choose those who are not good at it.

In fact, the way out for the birth of mathematics is not just a few choices:

Basic direction: continue to engage in scientific education research, teachers and professors. .....

Computational mathematics: (actually, it is a new branch of applied mathematics) mainly studies complex mathematics and the calculation of a large number of data, which can be involved in various industries. But the social demand is not great.

Applied Mathematics: This range is too large, and all kinds of applications involve all branches of mathematical knowledge. You can have a look, and there are many.

Operational control: The project mainly focuses on economy. If you are engaged in the financial industry in the future, most people in this direction will be in financial positions.

Probability statistics: To put it bluntly, it is to predict what the per capita income of China will be and what the world population will be in many years. This is what people who study this direction say.

Supplement: Actually, I study geomatics. I don't know how to collect data by simulated blasting and then analyze it with Matlab. There is also a software specially used to draw vibration waves according to the data. I forgot.

Most people think math is difficult, but it is not. It's just that you didn't devote yourself to your study. When you absorb a knowledge point and apply it, you will have a sense of accomplishment at that time.

Good luck. I believe you have a deeper understanding in every direction. As for what to choose, you still have to decide for yourself. Others can only make you better understand the role of each direction.

I hope I can help you!
