	I'm looking for a fairly simple (and inexpensive) Macintosh
program to help my students learn matrix manipulations.  All I want them
to be able to do would be row operations, but with non-trivial matrices
(i.e., bigger than 3x3, not nice numbers).  I know about APL and some
fancy packages, but is there something simple that doesn't take much
time to learn?  I'm thinking of something like 1)enter a matrix,
2) select a row, 3) drag it onto another row, 4) enter the multiple
of the first row to be added to the second row, 5) and so on.
Any pointers?
