## Abstract

We present examples of interesting problems that hopefully make the learning and the teaching of linear algebra enjoyable. The problems are on matrix multiplication, rank, determinants, eigenvalues and eigenvectors, and matrices and graphs. The problem solving strategies used include “look for invariants”, “check parity” and “define an energy function”.
