Overview ### ”You're a mathematics major? So, what are you going to do with it?”

**Mathematics Placement and Academic Support**

**Why Take More Mathematics Than is Required by Your Major or by the Salem Signature General Education Program?**

**Your Faculty**

**Your Program**

**Your Results**

The answer to this question is, “Whatever I want!” When you major in mathematics you are prepared to enter many different fields after graduation. One of our guiding philosophies is that if you couple your major (or minor) in mathematics with another major (or minor), your possibilities are endless. Some recent mathematics majors and minors at Salem have also completed undergraduate work in:

Accounting, arts management, biology, business administration, chemistry, communication, computer science, dance, economics, education, English, finance, French, German, history, interior design, international business, music, psychology, religion, sociology, Spanish, and studio art.

Our students have entered graduate and professional programs in mathematics, statistics, biometry, biology, chemistry, epidemiology, law, medicine, dentistry, economics, econometrics, accounting, religion, secondary education, educational statistics, public policy, nursing, secondary school administration, civil engineering, environmental engineering, and mathematics education. Our graduates have also found employment opportunities in a wide variety of fields after graduating from Salem, including public health, biostatistics, aviation consulting, fund raising, accounting, banking, financial planning, economics research, elementary, middle and secondary school teaching, and college and university faculty positions. We have alumnae who own their own businesses, who are well-respected artists, who have chaired boards, who are college professors, and who are award-winning high school teachers.

Opportunities for internships and summer research experiences are available locally, nationally, and internationally, and many of our students take advantage of study abroad opportunities in places such as Hungary, Japan, Germany, Australia, Hong Kong, Greece, and the United Kingdom.

On campus, mathematics majors and minors are active and visible participants in the Women in Science and Mathematics Program (WISMP), the Celebration of Academic Excellence, the QUEST Program, student life, and student government.

All undergraduate students entering Salem College take a Mathematics Placement Examination in order for the department to properly guide each student to the appropriate mathematics courses that satisfy Salem Signature requirements or that satisfy the requirements for her intended major. **Traditional-aged students** should click here for more information and Fleer Center students should click here for information and instructions. Students are encouraged to enroll in the course in which they are placed as early as possible during their Salem career so that they may benefit the most from the quantitative experience.

Academic support services are offered to students through the Office of Academic Support and through the QUEST Program for quantitative enrichment, science, and technology. The QUEST Center offers on-line resources and in-person tutoring for free to all Salem College students. The Mathematics Department also employs qualified work-study students whenever possible to provide free tutoring in many first- and second-year level courses.

Research continues to support the notion that women who take more mathematics courses in high school and in college experience a positive impact on future earnings. (See: Rose, Betz, *Math Matters: The Link Between High School Curriculum, College Graduation and Earnings*, 2001.) So, while you may only be *required* to take a single mathematics course for your major or for General Education purposes, we strongly encourage you to consider taking at least one additional course from our department in order to maximize your earnings potential, strengthen your applications for graduate or professional school, and increase opportunities for internships while a student at Salem College. Rest assured, we will help you and your advisor choose any and all mathematics courses which would be most beneficial to you based on your past mathematical experiences and your academic or career goals.

The mathematics faculty are active, engaged mathematicians who regularly participate in and present at national and international conferences and are committed to the undergraduate education of each Salem student, regardless of the student's major. With nearly seventy years of combined teaching experience at a variety of levels, and numerous teaching awards between them, you are assured a personal, professional, and individual experience, no matter how many mathematics courses you choose to pursue.

Success Stories

I was quickly won over by the genius, yet down-to-earth professors in the Math Department. My advisor, Debbie Harrell, is one of many unforgettable professors in the department who will give you all of the individualized attention you need to succeed. In College Geometry, Dr. Paula Young encouraged me to explore my love for sports in a class project where I looked at the fascinating geometry of basketball. In addition to the awesome faculty, class sizes are small and intimate. Your peer cohort is sure to bond as you triumph together through the Calculus course sequence, all the way into Real Analysis. The power of numbers is so strong, and mastering these techniques and problem-solving skills will give you an unparalleled confidence and sense of accomplishment.
Salem and its Department of Mathematics filled me with confidence to pursue what I thought was the unthinkable—six more years of school! Because of the relationships I formed, I was able to get amazing recommendation letters and had the credentials to get into a really great program for my field. I now do applied research on student-athletes at the national headquarters for the NCAA. I get to study the coolest topics relating to the college athlete experience such as academic performance, mental health and well-being, retention, major choice, relationships with coaches, and life after sport retirement.

I was quickly won over by the genius, yet down-to-earth professors in the Math Department. My advisor, Debbie Harrell, is one of many unforgettable professors in the department who will give you all of the individualized attention you need to succeed. In College Geometry, Dr. Paula Young encouraged me to explore my love for sports in a class project where I looked at the fascinating geometry of basketball. In addition to the awesome faculty, class sizes are small and intimate. Your peer cohort is sure to bond as you triumph together through the Calculus course sequence, all the way into Real Analysis. The power of numbers is so strong, and mastering these techniques and problem-solving skills will give you an unparalleled confidence and sense of accomplishment.
Salem and its Department of Mathematics filled me with confidence to pursue what I thought was the unthinkable—six more years of school! Because of the relationships I formed, I was able to get amazing recommendation letters and had the credentials to get into a really great program for my field. I now do applied research on student-athletes at the national headquarters for the NCAA. I get to study the coolest topics relating to the college athlete experience such as academic performance, mental health and well-being, retention, major choice, relationships with coaches, and life after sport retirement.
