The reader should be able to enter a matrix into a TI-83 or 84 calculator, have the calculator solve the corresponding system and interpret the results.

This packet consists of two technology demo videos-one for entering a matrix into the calculator and the other for getting the calculator to do the computations for solving the corresponding system of equations.

Tutorial

This packet assumes that you know how systems of equations are represented as matrices and that you know the rules for solving systems of equations by elimination and with matrices.

This is a technology packet-it gives explicit instructions for using a TI-83 or TI-84 to solve a system of equations with matrices.

This video gives explicit instructions for entering your system of equations as a matrix into the calculator.

This video demonstrates the explicit instructions for having the TI-83 or 84 put a matrix in reduced row-echelon form, which solves the system of equations.
