At Earlham, we strive to teach our students mathematical fundamentals and problemsolving skills that they can apply in a variety of disciplines or in further study of mathematics. We work to help students become a part of the intellectual and cultural community of mathematicians. We do this by supporting them in doing research either here or in summer Research Experience for Undergraduates programs. We also do it by encouraging them to take part in mathematical competitions, to enjoy activities like our Pi Day and Celebration of the Mind events, to learn from special lectures and lunchtime conversations about math, and to be a part of the supportive and stimulating community of people working in the Math Studio.
The Association for Women in Mathematics (Careers That Count) describes mathematics as "… a powerful tool for solving practical problems and a highly creative field of study, combining logic and precision with intuition and imagination. The basic goal of mathematics is to reveal and explain patterns — whether the pattern appears as electrical impulses in an animal's nervous system, as fluctuations in stock market prices, or as fine detail of an abstract geometric figure."
A solid preparation in Mathematics can lead to a career in any field where the ability to recognize and exploit patterns is fundamental. Over the past few years, Earlham Mathematics graduates have gone on in various directions. Some are in graduate school studying applied mathematics, actuarial science, computer science, education, engineering, environmental science, law, mathematics, medicine, musicology or theology. Others have become high school teachers, business managers, computer programmers, systems analysts, environmental statisticians, actuaries or mathematics professors. Some Mathematics graduates have enrolled in Earlham College's Master of Arts in Teaching Program, while others have attended Earlham School of Religion, Indiana, Oregon State, Miami and Stanford universities and the universities of Kentucky, Michigan and Wisconsin.

Offered for firstyear students. Topics vary. (ES)
*MATH 180 CALCULUS A (5 credits)
Calculus is the mathematical study of quantities that change with time and of areas and volumes. The development of calculus is one of the great discoveries of humanity, and the resulting discipline is of fundamental importance not only for students of the natural sciences, but also graduate work in the social sciences. Introduces major issues in calculus: functions, limits, derivatives and integrals. Concludes with the fundamental theorem of calculus, which relates areas to rates of change. (AAR, AQR)
*MATH 190 DISCRETE MATHEMATICS (3 credits)
A course in mathematical invention and discovery. Starting with simple but unfamiliar mathematical systems, students do calculations, look for patterns, and work to convince themselves and one another of the truth of their insights as they collectively explore and develop new mathematical worlds. An early glimpse of what mathematical research is like. Strongly recommended as an introduction to college mathematics. Topics include number theory, combinatorics, set theory, logic and induction. (AAR)
MATH 195 MATH TOOLKIT (2 credits)
An introduction to the principal topics in mathematics needed by a Computer Science major, and intended for students of computer science.
