The Applied Linear Algebra question collection contains more than 170 original questions with randomized answers that correspond to any introduction to linear algebra textbook. This collection was created by Bob Muncaster, an associate professor of mathematics at the University of Illinois at Urbana-Champaign and a longtime WebAssign user. Additional resources will be available soon.

Questions Available within WebAssign

Most questions from this textbook are available in WebAssign. The online questions are identical to the textbook questions except for minor wording changes necessary for Web use. Whenever possible, variables, numbers, or words have been randomized so that each student receives a unique version of the question. This list is updated nightly.
