# Calculators Cheap scientific calculator that does matrix operations

1. Jan 26, 2010

I do not have a calculator that does matrix stuff that would be great for my classes this semester. I don't want to spend $100+ on a graphing calculator since I use matlab at home strictly now. Im looking to solve simultaneous equations, matrix operations like det,eigen,mult,...etc Any help would be great! 2. Jan 27, 2010 ### story645 The TI line (83, 89, etc.) handles matrix math just fine, and some of them go for under 100. 3. Jan 27, 2010 ### cronxeh My Ti-89 is still a classic. The best you can get for the money. I wont bother with anything below Ti-89 4. Jan 27, 2010 ### bassplayer142 I was kind of aiming towards$20-30...

ebay? I haven't seen a graphing calculater under $80 in years, and I don't think non-graphing ones handle matrices. 6. Jan 27, 2010 ### bassplayer142 uhhg, maybe I can borrow one. Thanks everyone. 7.

It didn't seem like that was an exceptionally low price or anything, so you shouldn't have a problem finding one in your price range.
