The Department of Mathematical Sciences at Binghamton University offers courses and programs in mathematics, statistics and actuarial science. The main areas of concentration in the department are algebra, analysis, combinatorics, geometry/topology and statistics. The department offers both a flexible curriculum that allows students to construct a course of study that aligns with their own interests and goals, as well as a more intensive theoretical curriculum designed to be especially useful for students who wish to pursue graduate study in mathematics. The department also offers tracks in actuarial science that provide strong preparation for an actuarial career.

Students who major in mathematics gain mathematical reasoning and analytical skills that are beneficial in a broad range of careers. For example, in addition to educators (teachers and professors) at all levels, mathematics majors can pursue careers in data analysis, software development, national security, medicine and scientific research. Mathematics majors who specialize in actuarial science commonly find employment within insurance companies, consulting firms, federal and state insurance departments, universities, banks, investment firms, large corporations and public accounting firms.
