Abstract
Matrix algebra has become a familiar research tool
in recent years, but the teaching and learning problem
is still formidable for many individuals. The
purpose of this paper is to present a simple generalpurpose
method of handling matrices for solving
simultaneous equations, including those involved in
regression and linear programming problems.
High-speed computers and different methods are
now used in most practical analysis in this field, but
teaching must rely on manual approaches to illustrate
the mathematical principles. The method presented
here is believed to shorten learning time .and reduce
the memory burden. In short, this is an introduction
to matrix algebra in one easy lesson. The
author wishes to thank Rex Daly and Martin Abel
for suggestions that have helped to improve this
article.
