Mathematics B.S.

Students who major in Mathematics—the Queen of the Sciences—like patterns, puzzles, and challenges, and are curious about why things are true. Businesses, industries, and government agencies actively seek math majors for their strong analytical and abstract reasoning skills. A math degree also prepares you for many different types of graduate programs.

The Department of Mathematics is part of the Indiana University College of Arts and Sciences. In your coursework in the math department, you will meet world-class faculty who are recognized both for their contributions to the field and as award-winning teachers.

The Department of Mathematics offers four different types of undergraduate degrees:

  • The Bachelor of Arts (B.A.) offers you broad flexibility to combine your interest in math with almost any major, minor or certificate.
  • An interdepartmental major in mathematics and economics allows B.A. students to pursue one major that combines coursework from both disciplines.
  • The Mathematics B.S. gives a much deeper look at the subject. Within it, there are two different options: a B.S. I program, focusing on theoretical math, and a B.S. II program, concerned with mathematical applications.

As a math B.S. major you should investigate other opportunities available in the College of Arts and Sciences and beyond. The academic advisor and faculty can provide advice to you about combining math with another major or degree on campus.

The Mathematics department also offers a convenient and flexible math minor, designed to supplement any other major on campus.


Getting started

Math majors take a variety of courses from different areas of math. In fact, you may not yet be aware of the diversity that exists in the IUB math curriculum.

All math majors begin with the same sequence of required courses: three semesters of calculus and linear algebra. Taking these courses may help you determine which math degree is the best fit for you. After completing Calculus 1 and 2, the next steps are usually these two required courses:

  • Multivariable calculus – where calculus meets geometry in two and three dimensions
  • Linear algebra – lines, planes, vectors, matrices, and useful organizing principles

After that, you consider the two different B.S. programs: theoretical or applied math.

Tracks and concentrations

Math B.S. students study in depth the complex relationships between ideas in mathematics. Two Math B.S. programs are available: Program I, focused on theoretical math, and Program II, focused on applied math and related areas.

  • Program I requires more upper level and theoretical coursework than other math major options. In particular, you learn the foundations of the two main areas of mathematics. In analysis, you study functions, as in calculus. In algebra, you study symmetries and structures. Program I is recommended if you are interested in Ph.D. programs in mathematics. It can also be great training for a variety of other career fields.
  • Program II requires more applied math courses, including differential equations, computer programming, and an outside concentration from an area such as economics or a science. This program provides preparation for graduate school in applied areas such as finance, economics, statistics, informatics, computer science, and others. The B.S. II also complements another degree.

While any math major can help you prepare for a career as an actuary, the B.S. II program is especially relevant to actuarial studies. If you are interested in a career as an actuary you should plan to select two courses from the probability and statistics area. Particular courses from economics, computer programming and business will help you prepare for this popular and rewarding career field.

Upper level coursework

As a Math B.S. major you are required to take certain upper level math courses, including two analysis courses. Math B.S. I majors must also take two 400 level algebra courses while Math B.S. II majors take additional differential equations and an applied math sequence.

We encourage you to work with the academic advisor to discuss how the Math B.S. coursework will help you achieve your goals and complement your other interests.

Commonly pursued majors, minors and certificates

Math B.S. majors often pursue other degrees on campus or have an interest in additional minors or certificates. With the help of your academic advisor, you may be able to combine several areas of interest. The Economics B.A. degree is the most popular pairing.

You should investigate degrees and minors that will provide you with important skills to complement your math degree. Here are just a few ideas pursued by math majors at IUB:

Sometimes students majoring in other schools, such as the Kelley School of Business, Informatics, or the Jacobs School of Music, express interest in also pursuing a math major. The math academic advisor will work with you to find out if it is possible for you to combine your first degree with a concurrent second degree in math.

Math B.S. majors interested in teaching high school math should consider our special five year program, which combines the B.S. in Math with an M.S. in Secondary Education and a teaching certificate. This accelerated program allows you to earn a master's degree in secondary education by adding just one more year to your degree program. If you are interested in this program, please talk with your academic advisor to make sure you qualify and to plan your curriculum. The application for this program is due during fall of senior year, but it requires course planning much earlier.

If you are interested in a career as an actuary, you should consider adding the Economics minor.

Enhance your major

Working with faculty

When pursuing a degree in Mathematics, you have the opportunity to work with faculty who have expertise and experience in the field. Take advantage of office hours to talk with your instructors about your performance in class, the content of assignments, and how the course helps you work toward your goals.

Math majors are encouraged to apply for a Department of Mathematics Undergraduate Internship (UGI). This opportunity provides a small stipend and gives you applicable work experience grading papers, assisting faculty, and tutoring your peers.

The Indiana University Math Directed Reading Program (DRP) offers enthusiastic, highly-motivated undergraduate math majors the opportunity to learn advanced math topics in a structured, research-like environment. Participants spend a semester on an independent math project under the supervision of a graduate student mentor. Projects often take one of the following forms:

  • An introduction to a subject not covered by the departmental coursework.
  • An in-depth reading of a particular theorem or set of theorems.
  • A more advanced treatment of a standard subject.

The Laboratory of Geometry (LoGoffers students a chance to study a geometric concept deeply enough so that they could get a computer to produce meaningful pictures which would suggest further insights and conjectures. Students work in groups with other undergraduate students and with the help of a grad student and a faculty mentor. 

The National Science Foundation funds a large number of research opportunities for undergraduate students through its REU Sites program. The Math department offers a Research Experiences for Undergraduates (REU) program, providing undergraduates the opportunity to gain research experience over the summer. Talk with the academic advisor to learn more.

You can find other summer and semester long research opportunities through the American Mathematical Society, the Mathematical Association of America, and Pathways to Science.


The Department of Mathematics offers a departmental honors program for students interested in taking more challenging honors coursework in math. Most students enter this program with either S211 Honors Calculus 1 or S212 Honors Calculus 2 during freshman year. You can also start math honors with S311 Honors Calculus 3 or S303 Honors Linear Algebra during your freshman or sophomore year.

Most math honors students pursue a B.S. I program. If you are interested in departmental honors with the B.S. II program, talk with the academic advisor.

High achieving students may be recognized for Academic Excellence in the College of Arts and Sciences, or be eligible for admission to the Hutton Honors College.
