Abstract  
In this document the author provides a series of lessons and exercises through which students can learn some fundamental concepts about matrices and practice elementary matrix algebra. The author goes on to show how matrices can be used for representing the structure of a molecule in terms of the Cartesian coordinates. Symmetry operations on coordinates of molecules can be represented by matrix algebra. CH_{4} is the molecule used to illustrate a rotation matrix operation on the coordinate matrix to yield a new view of the molecule. This document would serve as an introduction to matrices and how they are used in physical chemistry. It would also be useful as a document for learning to use Mathcad. Development of this document was made possible by the NSFsupported 1997 "Workshop for Integration of Numerical Methods into the Undergraduate Physical Chemistry Curriculum Using the Mathcad Software" at the University of South Alabama, Mobile, Alabama.
