The BS in Mathematics develops the technical and analytical skills to analyze and solve problems logically and masterfully. Because so many careers require this essential skill, a degree in mathematics provides the gateway to endless career opportunities in virtually every industry.

Interested in applying your aptitude for math to real-world problems in science, computer science, engineering, business or industry? Applied mathematics might be your field. Here, you’ll take courses in calculus, statistics, discrete mathematics, operations research, numerical analysis, and physics and apply them to real-life situations, such as predicting the behavior of financial markets, explaining the risk factors of insuring a company, or building a bridge.

Actuaries assess the risk of an event occurring, and develop policies that help reduce costs associated with this event. To prepare for this lucrative career, you’ll take courses in calculus, the mathematics of finance, and numerical analysis, as well as courses in accounting, economics and business.

A minor in mathematics is an excellent complement to many majors, from accounting and finance to computer science, physics, management, and more. 

Mathematics majors who wish to pursue a career in education can obtain certification as a classroom teacher (grades 7-12) through STAC’s Adolescence Education program offered through the School of Education.
