The major in Mathematics is designed to meet two goals: to introduce some of the central ideas in a variety of areas of mathematics and statistics, and to develop problem-solving ability by teaching students to combine creative thinking with rigorous reasoning. The major requires nine courses plus colloquium. Students are urged to consult with the department faculty on choosing courses appropriate to an individualized program of study.

### Calculus

*2 courses*

- Mathematics 140 (formerly 104) Calculus II or an equivalent high school course
- Mathematics 150 or 151 (formerly 105 or 106) Multivariable Calculus

Except in unusual circumstances, students planning to major in mathematics should complete the calculus sequence (Mathematics 130, 140, 150/151) before the end of the sophomore year, at the latest.

### Applied/Discrete Mathematics/Statistics

*1 course*

- Mathematics 200 (formerly 251) Discrete Mathematics
- Mathematics 209 Differential Equations and Vector Calculus
- Mathematics 210 Mathematical Methods for Scientists (Same as Physics 210)
- Statistics 201 Statistics and Data Analysis Statistics
- 231 Statistical Design of Experiments
- a more advanced elective in discrete or applied mathematics or statistics, with prior departmental approval.

### Core Courses

*3 courses*

- Mathematics 250 (formerly 211) Linear Algebra
- Mathematics 350 (formerly 301) Real Analysis or Mathematics 351 (formerly 305) Applied Real Analysis
- Mathematics 355 (formerly 312, 315, or 317) Abstract Algebra

### Completion

*3 courses plus colloquium*

- The Senior Major Course is any 400-level course taken in the senior year. In exceptional circumstances, with the prior permission of the department, a student may be allowed to satisfy the Senior Major Course requirement in the junior year, provided that the student has completed three 300-level mathematics courses before enrolling in the Senior Major Course (if it is a statistics seminar, one of the 300-level courses may be replaced by Statistics 231).
- Two electives from courses numbered 300 and above or Statistics 231.
- Weekly participation as a senior in the Mathematics Colloquium, in which all senior majors present talks on mathematical or statistical topics of their choice.
