Welcome to the Department of Mathematics

Department of Mathematics at Illinois State University



The Mathematics sequence in the Mathematics major first provides students with a strong foundation in Mathematics and then gives students the flexibility to explore various aspects of the discipline.

There is also the flexibility within the Mathematics major for a student to pursue a minor in a related field of study. Such a program can prepare students for jobs in industry and government as well as prepare students for graduate study in Mathematics.

Why Study Mathematics?

Mathematics is one of the oldest and the most basic sciences divided in to two categories: Applied Mathematics and Theoretical Mathematics.

Theoretical Math is involved with advancing science by developing new principles and new relationships between existing principles of math. Applied Math uses the theories and formulates and solves practical problems in business, government, and engineering and the physical, life, and social sciences.
