Description: This takes all the arithmetic out of matrix problems. With this web site, the student types in their matrix, and then gives the computer the the row-echlon commands - no silly mistakes. This helps the student learn the concept with out being held down with calculations. It also has the ability to complety transform a matrix into rref while showing all the steps. A definite must see for any teacher.... It also works for inconsistent and dependent systems!

 Bethany Comment: Impressive free tool to take the drudgery of computation out of the linear algebra. It doesn't just do the computation for you either, it has a nice use of color to help instruct on how the computations are created.
