Major Requirements
In addition to the general college requirements, a major in mathematics must complete:
 MA126 and MA129 Calculus 1 and Calculus 2 (or equivalent)
 MA204 , MA220 and MA251 Calculus 3, Linear Algebra, and Number Theory (should complete before declaring the major)
 MA321 and MA375  Abstract Algebra 1 and Mathematical Analysis 1
 One of the following (which should be taken in the same year as its prerequisite whenever possible):
 Three other 300400 level oneunit courses, OR two other 300400 level oneunit courses AND two other 200 level one unitcourses not meeting one of the requirements above, (excluding Independent Studies: MA255 , MA355, MA455.) EC392 can also count as a 200level elective.
A student majoring in mathematics must also:
 Attend at least four departmental seminars or departmentapproved talks after declaring the major, and submit a onepage summary of each to the department chairperson within two weeks of the seminar. This should be completed by the end of Block 7 of the student's senior year. Consult the department for further details on what constitutes an approved talk. Need help with your seminar writeups? Download our helpful Seminar Writeup Handout to get a better idea of what is expected in your summaries.
 Complete a capstone experience intended to give the student an opportunity to engage mathematics in a deep and meaningful way. The capstone will challenge the student to read, write, and think about mathematics, drawing on the knowledge and skills that they have acquired throughout their studies. There are two ways to complete the capstone requirement:
 Pass MA408  History of Mathematics during the senior year. In this case, MA408 will not count as one of the 300400 level electives needed for the major.
 Complete a senior thesis. The thesis will involve either original research or substantial expository work. The student must have a thesis advisor in the department, and submit a thesis proposal to the department by the end of Block 3 of his or her senior year. The student must enroll in at least one block of MA499 (Senior Thesis) with his or her thesis advisor during the senior year. Consult the department for further details.
To be considered for graduation with Distinction in Mathematics, a student must complete three courses with a 300level prerequisite, one of which must be MA410. In addition, such students must complete a distinction project and be approved by a vote of the department faculty. (The distinction project satisfies the capstone experience requirement.) Further information is available from the department, and on the link above.
