1. Computer Science:

Computer science involves algorithm design, data structure, discrete mathematics and so on, and needs a good mathematical foundation. If you like computer science programming and problem solving, this major is a good choice.

2. Physics:

Physics is an experimental science, which needs mathematics to describe and explain the experimental results. In physics, mathematics is widely used, such as mechanics, heat, electricity, optics, quantum mechanics and so on. If you like exploring the laws of nature and the mysteries of the universe, this major is a good choice.

3. Engineering:

Engineering is an applied science and needs mathematics to solve practical problems. In engineering, mathematics is widely used, such as mechanical engineering, civil engineering, electrical engineering, aerospace engineering and so on. This major is a good choice if you like solving practical problems and designing new items or systems.

4. Statistics:

Statistics needs mathematics to analyze and interpret data. In statistics, mathematics is widely used, such as parameter estimation, hypothesis testing, variance analysis, regression analysis and so on. If you like processing data and analyzing problems, this major is a good choice.

5. Finance:

Finance needs mathematics for risk assessment and portfolio optimization. In finance, mathematics is widely used, such as stochastic process, mathematical statistics, econometrics and so on. If you like dealing with data and analyzing problems and are interested in the financial field, this major is a good choice.

In a word, mathematics is a basic subject, which is widely used, and many majors need a good mathematical foundation. If you are good at math, you can choose many majors, such as computer, physics, engineering, statistics and finance. Choosing a major that suits you needs to consider your own interests and abilities, as well as your future career development prospects and other factors.
