Because it's fun and can prepare you for a variety of excellent careers! If you like solving puzzles and figuring things out, then a mathematics major may interest you. In addition, applications of mathematics are everywhere and a strong background in mathematics can help you in many different careers.
Check out this website www.whenwilliusemath.com (from BYU). It describes what mathematics is useful for and what careers a background in mathematics can prepare you for.
The sections below provide information about careers in mathematics and the opportunities available to our mathematics majors.
The following links are to pages that provide information about the careers available to students of mathematics.
Two graduates of our department, Katie Fanning and James McCreary, are profiled in the American Mathematical Society's webpage about careers in mathematics. You can also view a slideshow about recent graduates from the department.
If you are considering graduate school in mathematics, you should think about participating in some research as an undergraduate. There are opportunities to do so with professors in our department or at other institutions during the summer at an REU (Research Experience for Undergraduates). REUs are usually four to eight weeks long and typically pay the student a stipend.
