# Linear Algebra (Math 220) Assignments

#### Spring Semester, 2004

Assignments are listed by the date due.

PDF and DVI (requires TeX software) versions of this page are available for printing.

Most of these assignments are simply exercises designed to prepare you for the weekly quizzes. You may find it helpful to discuss these exercises with others, but if you watch someone else do an exercise, you will likely lose its benefit unless you subsequently work through the exercise privately. It is generally not helpful to seek explanation of an exercise that you have not attempted. When you have trouble with an exercise, it is important to try to state in words exactly where in that exercise and in what way you find yourself blocked.
