The mathematics program at PLU is designed to serve five main objectives: (a) to provide mathematical background for other disciplines, (b) to provide a comprehensive pre-professional program for those directly entering the fields of teaching and applied mathematics, (c) to provide a nucleus of essential courses that will develop the breadth and maturity of mathematical thought for continued study of mathematics at the graduate level, (d) to develop the mental skills necessary for the creation, analysis, and critique of mathematical and quantitative topics, and (e) to provide a view of mathematics as a humanistic endeavor.

Beginning Classes

Majors in mathematics, computer science and engineering, and other sciences usually take MATH 151 and MATH 152. MATH 151 is also appropriate for any student whose high school mathematics preparation is strong. Those who have had calculus in high school may omit MATH 151 (see the Advanced Placement section) and enroll in MATH 152 after consultation with a mathematics faculty member. Those who have less mathematics background may begin with MATH 140 before taking MATH 151. MATH 115 provides preparation for MATH 140.

Business majors may satisfy the requirement for the business degree by taking MATH 128, 151, or 152. (MATH 115 provides preparation for MATH 128.)

Elementary education majors may satisfy the requirement for the education degree by taking MATH 123 and MATH 124. (MATH 115 provides preparation for MATH 123.)

For students who plan to take only one mathematics course, a choice from MATH 105, 107, 123, 128, 140, or 151 is advised, depending on the student's interests, preparation and math placement results.

Math Placement Test

A placement test and background survey are used to help insure that students begin in mathematics courses that are appropriate to their preparation and abilities. Enrollment is not permitted in any of the beginning mathematics courses (MATH 105, 107, 115, 123, 124, 128, 140, 145, 151, and 152) until the placement test and its included background survey are completed. The link to the placement exam and survey is available at banweb.plu.edu.

The policy of the Department of Mathematics regarding mathematics credit for students who have taken the AP Calculus exams (AB or BC) or the International Baccalaureate Higher Level Mathematics Exam (IBHL) is as follows:

Exam Score Credit
Score Credit
Credit
AB
3*
MATH 151*
AB
4,5
MATH 151
BC
3
MATH 151
BC
4,5
MATH 151 and 152
IBHL
4,5
MATH 151
IBHL
6,7
MATH 151 and 152

*Consult with instructor if planning to take MATH 152.

If a student has taken calculus in high school and did not take an AP exam or IBHL exam, then the student may enroll in MATH 152 after consultation with a mathematics faculty member. In this case, no credit is given for MATH 151.

Minimum Entrance Requirements

The Office of the Registrar determines whether a student meets the minimum entrance requirements. When a student has a deficiency, after taking the Math Placement Test, the student will receive a recommendation about how to remove the deficiency based on the test results.

If the test result shows that a student is qualified to take MATH 115 or a higher numbered math course at PLU, then the deficiency will be removed when the student successfully passes such a course. In addition, the student will receive Math Reasoning (MR) GenEd credit. Please be aware that credit taken from MATH 105, MATH 107, or any non-math course which carries the MR attribute does not remove a math deficiency.

If the Math Placement Test result shows that the student is not qualified to take MATH 115 or a higher numbered math course, the student will have to take a course at at community college to remove the deficiency in his or her minimum mathematics entrance requirement. The course content should be equivalent to or more difficult than high school algebra or geometry and it must be approved by the Department of Mathematics.

Mathematics and General Education Program Elements

All mathematics courses will satisfy the mathematical reasoning (MR) element of the General Education Program. At least 4 semester hours are needed. All mathematics courses will satisfy the natural sciences, computer science, mathematics (NS) element of the General Education Program (GenEd). At least 4 semester hours are needed. A course cannot simultaneously satisfy Mathematical Reasoning (MR) and Science and Scientific Method (SM) GenEd elements.

In fulfilling the Math Reasoning Requirement, students with documented disabilities will be given reasonable accommodations as determined by the director of disability support services and the appropriate faculty member in consultation with the student.

Mathematics and the College of Arts and Sciences Requirement
(see College of Arts and Sciences Requirements)

All mathematics courses will satisfy the logic, mathematics, computer science or statistics part of Option III of the College of Arts and Sciences requirement. A course cannot simultaneously satisfy Option III of the College of Arts and Sciences requirement and a GenEd element.

Mathematical Major Requirements

The foundation of the mathematics program for majors includes:

  • MATH 151, 152, 253: The three-semester sequence of calculus
  • MATH 331 (Linear Algebra)

Students with a calculus background in high school may receive advanced placement into the appropriate course in this sequence.

Students who have taken calculus in high school but do not have credit for MATH 151 do not need to take MATH 151 for the mathematics major or minor. However, they still need to complete the number of hours in mathematics as stated in the requirements.

Upper-division work includes courses in introduction to proof, linear algebra, abstract algebra, analysis, geometry, differential equations, numerical analysis, mathematical finance, and statistics. See the description of the courses and the major (either bachelor of arts or bachelor of science) for more detail. Students majoring in mathematics should discuss scheduling of these courses with their advisors. For example, MATH 499 extends over two semesters beginning with MATH 499A in the fall semester. May graduates begin this capstone course in the fall semester of the senior year, while December graduates must make special arrangements with the department chair by the start of the Fall Semester in the year preceding graduation.

A grade of C or higher is required in all prerequisite courses.
