CSUSM Department of Mathematics Mathematics students will develop the ability to explore, conjecture, and reason, as well as solve a variety of problems.

Opportunities for students with a strong background in mathematics are as diverse as they are plentiful. Medical schools, law schools, graduate schools, and employers in fields such as economics, accounting, management sciences, mathematics, natural sciences, social sciences, computer science, statistics, and communication seek graduates in mathematics. Mathematics majors can pursue a career in the teaching of mathematics at the K-12 level or college level. A degree in Mathematics from California State University San Marcos prepares you to meet any of these challenges, and our faculty are committed to helping you achieve your goals.
