The Mathematics requirement for graduation consists of a three-year sequence of courses: Mathematics I, II, and III. These courses emphasize modes of mathematical reasoning and techniques of problem solving through the traditional topics of algebra, geometry, and right-triangle trigonometry. Students who wish to continue their study of mathematics have a variety of electives to choose from. Precalculus, Statistics, AP Calculus, AP Statistics, and AP Computer Science are offered every year. There is also a changing menu of various special electives that are offered occasionally, including Non-Euclidean Geometry, Chaos Theory, Discrete Mathematics, Evolution of Mathematics, and Decision Theory.
