This application allows the student to work through several examples of a 3 by 3 system and to see the geometrical result of individual row operations. The system can be presented either as a system or as an augmented matrix. The application takes a bit of getting used to, but works well.

User can control coefficients of the three linear equations in \(\mathbf{R}^3\) and see the dynamic change of the three planes as the coefficients are being changed.
