There are a lot of open source math programs, but only a few have a Computer Algebra System.

An interesting program is Sage Mathematics, which is actually glue code between other math software.

Sage has many good features:

- Interactive learning
- Web interface/server
- Graphing (2D and 3D)
- Algebra, Calculus, and up...
- Web interface has multiple accounts, and is easy to administrate.

They have instructions on the Sage Math website for building from source, so I tried it with the current release, Sage 5.8.

It was not easy to compile, and took a lot of time, so I am distributing a binary tarball so people do not have to build it themselves.

I have not run the doctests yet, but plan to, and will post the results when done.

Chromium is the best browser for using the web interface, because it is fast and supports Javascript.

There are links to the binaries at http://github.com/ArchimedesPi/SageMathematics-raspi/

I *just* finished building/packaging/uploading Sage 6.0, it's great, I have it on the previously mentioned page.

So I've build Sage [5.8, 6.0] currently,
