## Programs of the Department

Students in the Department of Mathematics are encouraged to develop superior thinking and problem-solving skills in preparation for mathematics-based careers and continued study. Our mathematics programs prepare students for a range of careers in education, industry and government. The mathematics major is also recommended for students planning for graduate or professional school.

The Department of Mathematics offers the following programs:

- A major in Mathematics, in which there are four concentrations
- A minor in Mathematics, designed to enhance major programs to which mathematics is readily applied
- Two combined major programs, offered in conjunction with the Department of Computer and Information Sciences

### Major in Mathematics

The Mathematics major has four areas of concentration from which to choose:

- The Mathematics Secondary Education Concentration, offered in conjunction with Towson UTeach, is designed for students who wish to become certified to teach mathematics in secondary schools.
- The Pure Mathematics Concentration emphasizes abstract mathematics and provides a strong background in mathematical theory, and prepares students for positions as researchers or analysts as well as for graduate study.
- The Actuarial Science and Risk Management Concentration, designated as a Center of Actuarial Excellence by the Society of Actuaries, provides students a solid background in mathematics along with specialized knowledge leading to career opportunities in the actuarial and financial professions.
- The Applied Mathematics Concentration provides a strong background in the foundations of applied mathematical methods, and is designed for students who wish to apply mathematics to problems in business and industry.

The Bachelor of Arts degree may be earned by adding the intermediate level of a foreign language or its equivalent to the major course requirements.

### Second Major Programs

Students may declare a second major and obtain a degree certifying that both majors have been completed. The Department of Mathematics encourages majors to pursue a second major or a minor in subjects in which mathematics is applied. In cooperation with the Department of Computer and Information Sciences, the following courses of study have been developed:

- The combined major in Mathematics and Computer Science
- The combined major in Mathematics and Computer Science with the Security Track

## Departmental Policies
