## Introduction

Mathematics has always been a fundamental component of human thought and culture, and the growth of technology in recent times has further increased its importance. UNC–Chapel Hill offers several degrees in mathematics and the mathematical sciences, providing students a choice of careers in this field. Among the jobs in industry, government, and the academic world that involve mathematics are actuary, analyst, modeler, optimizer, statistician, and computer analyst.

Students intending to teach mathematics in elementary and middle school and students enrolled in the School of Education who intend to major in mathematics should consult the School of Education section of the *Catalog* or the director of mathematical education in the Department of Mathematics. A section in the mathematics program of the *Catalog* suggests course selections for future high school teachers.

## Advising

All majors and minors have a primary academic advisor in Steele Building. Students should regularly meet with their advisors and review their Tar Heel Trackers to be sure that they are satisfying distribution and degree requirements. In addition, junior and senior majors are assigned each semester a mathematics faculty member as an advisor with whom they must meet to discuss course selections and any other questions before a hold on registration is lifted. The department’s director of undergraduate studies, assistant director of undergraduate studies, and manager of student services (see contact information above) are also available by appointment. Further information on courses, undergraduate research opportunities, the honors program, careers, and graduate schools may be obtained from the department’s Web site.

## Placement into Mathematics Courses

Standardized test scores such as the Advanced Placement (AP), Scholastic Achievement Test Subject Levels I or II (SAT), or the American College Test (ACT) can be used for placement into mathematics courses. Please visit the placement page of the department’s Web site for specific information regarding placement.

## Graduate School and Career Opportunities

The B.S. degree program, especially if it includes the sequences MATH 521–MATH 522 and MATH 577–MATH 578, is excellent preparation for graduate study in the mathematical sciences. The B.A. degree can be excellent preparation for graduate study in many fields, including admission into professional schools of law, business, and medicine. Both degrees are viewed by many employers as attractive, especially when accompanied by electives in areas such as statistics, computer science, economics, and operations research. Undergraduate mathematics majors with critical thinking skills and good analytical abilities are in demand in many business, industry, and government fields.
