**Purpose:** To explore the properties
of inverse matrices. Our principal tool for this exploration is the expression
of elementary row operations as left multiplications by elementary matrices.

**Prerequisites:**

- The Helper Application Tutorial for your computer algebra system
- The ability to perform elementary row operations to reduce a matrix to its reduced row echelon form.
