Welcome to the official web presence of the department of mathematics and computer science! What you'll be finding on these pages is mainly information on our courses, major/minor requirements, and faculty. Xavier has had a major in mathematics since 1916, and a major in computer science since 1975. While both programs continue to evolve, our primary goal remains unchanged. We want to provide an educational environment in which students can develop their abilities to undertake intellectually demanding tasks in both mathematics and computer science. Both of our programs support Xavier's mission by emphasizing critical thinking, logical reasoning, and the precise expression of ideas in the respective languages of the two disciplines.

With introductory classes of sizes in the 20s and smaller upper level classes, individual attention and faculty expertise are readily available. Each student in our department receives individual counseling from members of the department. The faculty believe that the best teaching can be done only when there is close faculty-student interaction for discussion, thinking, and exploring.
