A degree in mathematics is useful for those seeking careers in fields in which analytical skills are a requirement such as teaching, business, and data science.

The **traditional mathematics major** is appropriate if students plan to teach or continue their education after graduation, or if they seek an interesting major within the liberal arts.

The **applied mathematics major** is suggested if a student plans a career in actuarial work, industrial mathematics, or applied statistics.

The **minor in mathematics** consists of 21 units of required course work. Please refer to the Degree Requirements section for more information.

**U20 Math 210 The Art of Mathematical Thinking**

Mathematics plays an important role in society, from engineering to architecture to the social and behavioral sciences. This course will expose non-math majors to fascinating sides of mathematics that are typically not discussed in standard math courses. Students will learn effective thinking techniques with applications beyond standard mathematics, and discover exciting ideas and new perspectives about the world. We will look at questions like: What do rabbits, piano keyboards, and pine cones have to do with the Parthenon? What do secret codes and bar codes have to do with number systems and prime numbers? What are some uses and misuses of mathematics in everyday life? Why are coincidences not so amazing after all?
