Math freeware?

[Rhine720]

I'm sorta budgeted at the moment.. So freeware would be nice, but feel free to list what ever resources. I want some program that can help me learn math or atleast give me extra practice. Saying upper level of algebra and geometry and trig and calculas

In thinking some more, this is probably the best free reference for basic algebra:

For problems, I agree with socrunningman. Just get some books from the library and do the exercises. Try to find ones with a good answer key so you can understand how they got the solution. For calc, something like Stewart has a good range of questions and a decent answer key book. It is also easy to find an older version (like the 5th edition) for about $5.
