To meet the challenges, opportunities, and responsibilities encountered after graduation, mathematics majors are encouraged to obtain a broad but firm foundation in the discipline.

Majors acquire skill in the use of mathematical methods for dealing with problems from a variety of disciplines, and complement these tools with some training in computer science.

The math department offers two disciplinary majors, a B.A. and a B.S., and one disciplinary minor.

Requirements for the Major (B.A.)

disciplinary, 11 courses

MATH 135, MATH 204, MATH 232 and MATH 471; CPSC 124; either MATH 331 or MATH 375; two additional Mathematics courses at the 200-level or above; one additional Mathematics courses at the 300-level or above; and two additional courses chosen from Mathematics (MATH 131 and above) and Computer Science (CPSC 220 and above).

Requirements for the Major (B.S.)

disciplinary, 15 courses

MATH 135, MATH 204, MATH 232, MATH 331, MATH 375 and MATH 471; CPSC 124; three additional Mathematics courses at the 200-level or above; one additional Mathematics courses at the 300-level or above; one additional Computer Science course (CPSC 220 and above); and three additional courses in the Natural Science division that count towards the major in their respective departments.

Requirements for the Minor

disciplinary, 5 courses

One course at or above MATH 300 and four additional MATH courses at or above MATH 131.


Our students choose from a variety of introductory and advanced courses, each designed to provide students with an understanding of mathematical theories and methods from a variety of disciplines.

Below, you'll find a sampling of some of our most popular classes, as well as suggestions for making Math a part of your larger interdisciplinary experience at Hobart and William Smith Colleges.

MATH 278 Number Theory


Couple reason with imagination and consider a number of theoretic problems, some solved and some unsolved, within topics like divisibility, primes, congruencies and more. Then, enroll in PHYS 285 Math Methods, and study techniques that are useful in physical science problems like differential equations, multiple integrals and complex variables.

MATH 350 Probability


Learn the basics of probability functions while developing the skills needed to solve problems and build models. Once you’ve mastered probability, try ECON 202 Statistics, and study the methods of descriptive and inferential statistics that are most important to the study of economics by constructing your own survey, collecting data and then analyzing the data using methods learned during the course.

MATH 380 Mathematical Logic


Establish first order logic as a basis for understanding the nature of mathematical proofs and constructions like sentential logic, logical proofs and models of theories, and to gain skills in dealing with formal languages. If logic interests you, why not enroll in PHIL 240 Symbolic Logic, and study the techniques and theories of formal logic such as the theory of deductive reasoning and the concepts of validity, soundness, completeness and consistency.
