So, today I finally SAGE downloaded and have been playing with it.

It's pretty fun to use, and helpful if I don't want to pull out my calculator, or need something a little powerful. It's not the easiest thing to use, though, and can be quite annoying. I intend to use it, and a lot of index cards, on some of the new
USAMTS problems over winter break.
