# Courses and Requirements

*The goal of Hamilton’s Mathematics Department is to enable students to analyze and organize information using quantitative and statistical tools, to reason and argue logically, to employ appropriate problem-solving strategies, and to communicate complex ideas clearly and efficiently.*

Students may earn departmental honors by completing courses that satisfy the concentration with an average of 3.6 or higher, by taking a fourth full-credit elective that is at the 300 level or higher, and by making a public presentation to the department on a mathematical topic during their junior or senior year.

A minor in mathematics consists of 116, 216, 224 and two mathematics electives.

While all mathematics courses satisfy the QSR requirement, students seeking an entry-level course only for this purpose are encouraged to consider COLEG 105S: A World of Impending Disaster.
