Introduction to the concept of matrices.

Different types of matrices discussed. Matrix algebra including addition, subtraction and multiplication. Matrix inverses and determinants.

Matrix Addition and Subtraction. Reduction to Row Echelon Form. Many times we come cross systems of equations and we're usually at odds with how to solve them. Most times we deal with two-variable or three-variable systems of equations but the methods explained in this section can be used to solve any number variable system of equations. The trick is picking which one would work better and faster for you.
