Mathematics is a broad discipline that contains a range of areas of specialization within it. The required core courses provide fundamental background for mathematics in general. The concentrations allow the student to broaden this background or begin to specialize. Students must complete the core courses and a concentration.

An entering student in mathematics should have academic preparation to enroll in MATH 220 during the first semester. Admission to MATH 220 requires an acceptable ALEKS score. A student should attain grades of B in calculus in order to complete the advanced courses successfully.

The Department of Mathematics sponsors the Mathematics major, including the Teaching of Mathematics concentration; the Mathematics minor; Teacher Education Minor in Math, Grades 9-12; the Actuarial Science major; and a major in Mathematics and Computer Science in coordination with the Department of Computer Science.

### The Department of Mathematics offers the following majors:

Actuarial Science- an interdisciplinary subject involving mathematics, statistics, and financial economics. It is designed to prepare students to enter the actuarial profession, as well as to provide a background in quantitative finance and risk management.

Mathematics- Students must select a concentration in consultation with their adviser:

- Mathematics Concentration
- Graduate Preparatory Concentration
- Applied Mathematics Concentration
- Operations Research Concentration
- Teaching of Mathematics Concentration

Mathematics and Computer Science-Prepares students for professional or graduate work in mathematics and computer science.
