Penn State MATH 220: Matrices
MATH 220 is Penn State's compact linear algebra course (systems of linear equations, matrix operations, determinants, vector spaces basics, and eigenvalues) required across engineering, science, and data-oriented majors, usually taken alongside the calculus sequence.
Fennie is independent and not affiliated with Penn State University. This is an unofficial study guide.
What makes it hard
Two credits is the trap: students allocate two credits of attention to a course that introduces eigenvalues within weeks, and the half-sized format means every class meeting carries double weight. The computations are mechanical but unforgiving (one arithmetic slip in a row reduction invalidates everything after it) and the conceptual material arrives faster than intuition forms.
What you'll cover
- • Systems of linear equations and row reduction
- • Matrix algebra and inverses
- • Determinants
- • Vector spaces and independence basics
- • Eigenvalues and eigenvectors
The MATH 220 study guide
How to study for Penn State MATH 220, step by step.
- 1
Give it three credits of attention
MATH 220 moves from row reduction to eigenvalues in half a semester's worth of meetings. Schedule real weekly study time from day one. The two-credit label is how this course ambushes people.
- 2
Drill row reduction for accuracy, not just understanding
The method is simple; the arithmetic is where points die, because one slip invalidates every step after it. Practice slowly and check each row operation until error-free reduction is routine.
- 3
Verify your answers the cheap way
Linear algebra is self-checking: multiply your inverse back, substitute your solution, plug eigenvectors in. Building the verification habit converts silent exam errors into caught ones.
- 4
Attach meaning to eigenvalues early
Av = λv deserves more than memorization. Work small examples until you can say what an eigenvector is geometrically. The concept questions, and every later course that uses MATH 220, lean on that intuition.

FAQ
Is MATH 220 at Penn State hard?
The material is approachable, but the compressed format isn't: eigenvalues arrive within weeks, and arithmetic accuracy in row reduction decides more points than understanding does. Students who under-schedule it because it's two credits are the standard casualty.
What does MATH 220 cover?
Core matrix methods: solving linear systems with row reduction, matrix algebra and inverses, determinants, the basics of vector spaces and linear independence, and eigenvalues and eigenvectors.
When should I take MATH 220?
Most plans slot it alongside MATH 140 or 141. It needs little calculus. Taking it before courses like MATH 250 and the engineering core that quietly assume matrix fluency is the move that pays off.
More Penn State courses
MATH 140: Calculus With Analytic Geometry I
MATH 140 is Penn State's Calculus I (limits, derivatives, applications of differentiation, and an introduction to integration) required for engineering, science, and math-track majors. Grades hinge on two common evening midterms and a comprehensive final, with a long-standing weed-out reputation.
MATH 141: Calculus With Analytic Geometry II
MATH 141 continues the calculus sequence with integration techniques, applications of integrals, sequences and series, and parametric and polar topics. Among Penn State students it's widely regarded as the harder half of the sequence, with the same evening-exam, curved-grading format as MATH 140.
MATH 110: Techniques of Calculus I
MATH 110 is Penn State's applied calculus course for Smeal business majors and other non-engineering programs: derivatives, optimization, and basic integration with business applications, no trigonometry. It's one of the largest math enrollments at Penn State.
MATH 230: Calculus and Vector Analysis
MATH 230 is Penn State's multivariable calculus course: vectors and 3D geometry, partial derivatives, multiple integrals, and vector analysis through line and surface integrals and the big theorems. It's the third course in the sequence for engineering and science majors, with the familiar evening-exam format.
