(MA30) MathematicsComputer Science B.S.
B.A. effective Fall 1998. B.S. effective Fall 2010.
Faculty advisors: Daniel Kane, Brendon Rhoades, Rayan Saab
This major gives mathematically minded students a specialization in theoretical computer science. It is not equivalent to an undergraduate degree in computer science nor is it meant to substitute for such. However, since computing applications often require a strong foundation in mathematics, this major could help to prepare someone to work in such a setting. (An internship could provide additional valuable training.) Course requirements include abstract algebra, statistics or probability, combinatorics, numerical analysis, and at least three of each of lower division and upper division courses in computer science. Up to 16 additional units of upper division coursework from approved course lists in mathematics and/or computer science are required.
Updates to the major
The following course substitutions and electives have been approved by Academic Senate and will be posted in the 20182019 Interim Catalog Update:
 CSE 15L is a required lower division course for 20182019 entering MathCS students.
 MATH 154 can substitute for MATH 184A in the Combinatorics requirement.
 MATH 171A and/or MATH 171B can count as List A electives.
 MATH 157 can count as a List B/C elective.
 MATH 160A and/or MATH 160B can count as List B/C electives.
 MATH 185 can count as a List B/C elective.
 MATH 187A and/or MATH 187B can count as List B/C electives.
 MATH 189 can count as a List B/C elective.
 CSE 131 can count as a List B/C elective.
 CSE 110 can count as a List B/C elective.
 MATH 104A and/or MATH 104B can count as List C electives.
If you would like any of these substitutions to count toward your major requirements, please notify us on the VAC and we’ll update your degree audit.
A note on duplication of credit
The UCSD Registrar’s Office no longer enforces duplication of credit between MATH 170A and MATH 174. You can disregard any mention of duplication of credit between these two courses when reviewing your major requirements.
