Calculators

So, in high school we were pretty much made buy a TI-89 Titanium. While it's a really great calculator, I don't need it at all. When I was done with high school, I chose a non-math career, my math skills also dropped, but that's to be expected.

Anyway, what should I do with it?

Taxes.
