Matrix Algebra made easy

Solving systems of equations with three or more variables is a complex operation to do by hand. Using traditional graphing calculators, it can still be complex. But there are some good tablet applications that make this work very easy and are intuitive to use. On my Asus Transformer I especially like Mobilecatronics Math Pak (which also has a wicked easy interface for statistics and various types of regressions). On my IPad, two outstanding apps are MatrixAlgebra from Remington Technologies and Matrices.Curves by Karim Kanoun. Here is a short video showing these two apps and how easy and intuitive they are to learn.
