Mathematics:  

Mission: The Mathematics program at Moravian College fosters a community of faculty and students who promote the aesthetic, theoretic, and pragmatic qualities of mathematics in order to develop in its students communication and problem solving skills applicable to many disciplines that prepare them for fulfilling careers.

The Mathematics and Computer Science department offers three tracks for students in Pure Mathematics, Applied Mathematics, or Actuarial Science.  Study in this department ensures you'll gain valuable skills that will help you throughout your work life. You'll learn how to problem-solve and how to approach mathematics as a tool while gaining an in-depth knowledge of software and systems concepts in computer science, learning where they may fit in the quickly growing field of technology.

Pure Mathematics Track:  Student interested in a broad mathematics background or students who plan to attend graduate school in mathematics should consider the Pure Mathematics Track.  The Pure Mathematics track also provides quantitative and analytical skills, which prepare students to enter the workforce after graduation. Early, Middle, and Secondary education students are encouraged to follow the Pure Mathematics Track.

Applied Mathematics Track: Students interested in working in business or industry or students who plan to attend graduate school in applied mathematics should consider the Applied Mathematics Track.  The Applied Mathematics Track provides a strong foundation of mathematics and the tools required to solve real-world problems.

Actuarial Science Track:  Students interested in becoming an actuary should follow the Actuarial Science Track. An actuary is a mathematician trained to analyze information to calculate the monetary value of risk.  Actuaries progress in their professional career by passing a series of actuarial exams. The Actuarial Science Track prepares students for the first two actuarial exams (EXAM P and FM), giving them a solid foundation to begin a career as an actuary.  

Computer Science:

Computer science is the study of information processes and the creative application of abstraction and formal reasoning to solve problems. With the ever-increasing ubiquity of computational devices, computer science is an important field of study with diverse applications. From the natural and social sciences to the arts and humanities, computer science has become woven into the fabric of business, research, and everyday life.

At Moravian, the computer science program prepares students for professional life or graduate study. The core curriculum integrates a study of the theoretical underpinnings of the discipline with the practice of programming. Elective offerings explore the breadth of the discipline and expose students to the applications of computer science.

The Major in Mathematics

The Mathematics program consists of three distinct tracks: Pure Mathematics, Applied Mathematics, and Actuarial Science.  All mathematics majors are required to select a track when declaring their major.

All three tracks require the following four courses:  MATH 170 (or its equivalent sequence MATH 106 and MATH 166), MATH 171, 211, and 212.   In addition, all three tracks require a capstone experience. MATH 370 will serve as the capstone experience for most majors. Successful completion of MATH 400-401 (Honors) can serve as an alternative capstone experience, although students who plan to pursue an Honors project are encouraged to take MATH 370 in their junior year.  In addition, students must have at least three courses numbered 310-380, 390-399, or 400-401. (One of these three may be MATH 370.)

In order that students may understand and experience the depth and breadth of mathematics, the department’s major courses (other than the required courses and MATH 370) have been grouped into two areas: pure mathematics courses and applied mathematics courses.  

Current catalog courses in each of these areas are as follows:

Pure Mathematics Courses: MATH 220, 313, 327, 328, 329, and 340
Applied Mathematics Courses:  MATH 214, 221, 225, 231, 251, 332 and PHYS 343.
As special topics or new courses are offered, they will be placed in the appropriate group.

Pure Mathematics Track:
In addition to the four required courses and the capstone experience, the Pure Mathematics Track requires five additional courses in Mathematics.  One of these courses is a required course, MATH 220. For the remaining four courses, students in this track will choose three Pure Mathematics Courses and one Applied Mathematics Course.  
Students in the Pure Mathematics track must also choose two co-requisite courses from the following group of four courses: PHYS 111, PHYS 112, CSCI 120 and CSCI 121. Substitutions for this requirement may be made only with the approval of the Mathematics and Computer Science Department.

Applied Mathematics Track:  
In addition to the four required courses and the capstone experience, the Applied Mathematics Track requires six additional courses in Mathematics.  Two of these courses are required courses, MATH 220 and 221. For the remaining four courses, students in this track will choose three Applied Mathematics Courses and one Pure Mathematics Course.  

Applied Mathematics students must also choose two co-requisite courses from the following group of four courses: PHYS 111, PHYS 112, CSCI 120 and CSCI 121. Substitutions for this requirement may be made only with the approval of the Mathematics and Computer Science Department.

Actuarial Science Track:  
In addition to the four required courses and the capstone experience, the Actuarial Science Track requires six additional courses in Mathematics; three required courses and three electives numbered 210 or higher.  The additional required courses are MATH 231, 332 and 251. The three additional electives must include at least one Applied Mathematics Course and at least one Pure Mathematics Course.

Actuarial Science students must also take three co-requisite courses, which includes CSCI 120, ECON 152, and one ECON course chosen from the following group of three courses: ECON 225, 226 and 256.  Substitutions for this requirement may be made only with the approval of the Mathematics and Computer Science Department.

Secondary Education Certification:
Students planning to teach mathematics in secondary schools who are interested in the Pure Mathematics Track must complete the following courses: MATH 170 (or its equivalent sequence MATH 106 and  MATH 166), 171, 211, 212, 220, 231, 347, 348, 370, and one of the following: MATH 324, 365, or 366.

Students planning to teach mathematics in secondary schools who are interested in the Applied Mathematics Track must complete the following courses: MATH 170 (or its equivalent sequence MATH 106 and MATH 166), 171, 211, 212, 220, 221, 231, 347, 348, 370, and one of the following: MATH 230, 258, 251, 337, or PHYS 343.

Middle Level  Education Certification:
Students who are seeking certification in middle level education with a major in mathematics can complete either the Pure or Applied Mathematics Track.

Early Childhood Education Certification:
Students who are seeking certification in early childhood education with a major in mathematics should take the Pure Mathematics Track and are required to complete PHYS 111. The second co-requisite course is waived for these students. Students who are pursuing early childhood teacher certification with a major in mathematics do not need to complete MATH 125.

Courses in Mathematics (MATH) are listed below.

The Minor in Mathematics

The minor in mathematics consists of five course units in mathematics: MATH 170 (or the equivalent sequence Mathematics MATH 106 and MATH 166), MATH 171, and three MATH courses numbered 210 or above, including at least one of the following: MATH 212, MATH 220, MATH 231.

The Interdepartmental Major in Mathematics

The six mathematics courses that meet Set I requirements are MATH 170 (or its equivalent sequence MATH106 and MATH166), MATH 171, MATH 211, and three additional MATH courses chosen by the student with the approval of the advisor. Mathematics courses to be taken to satisfy Set II requirements will be determined by the student's prior preparation in mathematics and his or her educational objectives.

Courses numbered CSCI 286, CSCI 288, or CSCI 381-388 and courses from other schools may not be used to satisfy the major requirements without prior written departmental approval. The major also requires MATH 170 (or its equivalent sequence MATH 106 and MATH 166), MATH 171, MATH 216, and one additional MATH course numbered 210 or higher, or a two-semester laboratory sequence in science. Because analytic and abstract reasoning is important to the study and application of computer science, majors are encouraged to take additional coursework in science, mathematics, and logic.
