BA in Mathematics & Computer Science

Mathematics, statistics, and computer science are the subjects making up the “Mathematical Sciences.”  The Joint Major in Mathematics & Computer Science allows students to explore all of these related disciplines and is appropriate for Mathematics majors with an interest in applications in computer science and Computer Science majors wishing to have more breadth in foundations and applications. Mathematics & Computer Science majors should have advisors in both the Mathematics & Statistics Department and the Computer Science Department.

Learning Outcomes

Students completing the concentration in Mathematics & Computer Science will have:

  • In-depth knowledge in the mathematical foundations
  • Programming software engineering skills
  • Combined theoretical and technical skills to use on real-world applications


All students entering as freshmen in Fall 2018 and after will pursue coursework in the BU Hub, a general education program that is integrated into the entire undergraduate experience. BU Hub requirements are flexible and can be satisfied in many different ways, through coursework in and beyond the major and, in some cases, through co-curricular activities. Students majoring in Mathematics & Computer Science will ordinarily, through coursework in the major, satisfy BU Hub requirements in Quantitative Reasoning. Remaining BU Hub requirements will be satisfied by selecting from a wide range of available courses outside the major or, in some cases, co-curricular experiences.

Principal Courses

Unless otherwise noted, all required courses are 4 credit hours.
