Applied mathematicians, on the other hand, use mathematics to develop theories and techniques to solve practical problems in business, industry, government, engineering, and the natural and social sciences. Applied mathematicians use computers extensively to solve complex problems and to process large amounts of data. Once you have selected between theoretical and applied math, you'll take a core of courses in your particular area of concentration. Required courses for both concentrations include Calculus I and II and Linear Algebra for Undergraduates. All math majors must earn a minimum of 120 credit hours to earn the B.S. degree?41 credit hours in the major; 46 hours in general education courses (subjects such as English, humanities, social and behavioral sciences, natural sciences, history, informatics; and the remainder in electives.

Once you've completed your degree requirements, usually near the end of your senior year, you'll take a written examination covering your entire undergraduate mathematics program. Your success on this exam, coupled with an Indiana University degree, provide compelling evidence of your preparation and strong foundation of knowledge in the field of mathematics to employers.
