A math professor teaches college students and, at many schools, also does research. There are two main doors. Community colleges and many teaching-focused colleges hire people with a master's degree (43% of workers in this field). Universities and tenure-track research jobs usually want a Ph.D. (37%). The path has three stages. First you build real mathematical depth and the habit of proving things. Then you become job-ready by earning a graduate degree, gaining teaching experience, and learning to explain ideas clearly. Finally you grow into an expert through research, curriculum design, and

Stage 1 of 3 · about 40 weeks
Build the proof-based mathematical core every math professor needs: calculus, linear algebra, and the ability to read and write proofs.
Calculus and differential equations
These are the courses you will teach most often, especially at community colleges and in service courses. You must know them so well that you can predict where students get stuck, such as the chain rule, u-substitution, or separation of variables.
Linear algebra
Linear algebra is the language of modern mathematics, statistics, and data science. It is also a core course you will likely teach. Learning vector spaces, eigenvalues, and matrix decompositions gives you a base for nearly everything later.
Proof writing and discrete mathematics
Upper-level math is about proof, not computation. Induction, contradiction, and contrapositive are the tools you will use daily and teach to others. Discrete math, including logic, sets, counting, and graphs, is also a core course you will be asked to teach.
Probability and statistics
Statistics and actuarial science are named in the job description. Many departments need people who can teach intro statistics, which serves the largest number of students.
Mathematical writing with LaTeX
Professors write exams, handouts, papers, and recommendation letters in LaTeX. It is the standard of the field and it is free.
