Hey all, I've been using a TI-83+ Silver Edition for the past two years, and recently, it's died on me. Changing batteries (back up battery included) does nothing; I've tried multiple sets of triple As. Thus, I believe this calculator is dead and it's time to get a new one (Though I'm really surprised it didn't last longer ). I've already checked if the text was really light and things like that. Now, next year I'll be doing pre-calc, trig, etc etc so I'd like a calculator similar to the TI-83+ Silver Edition (I like the TI GUI, what can I say? ) Any suggestions? Should I just pick up another TI-83+ Silver Edition? (I believe they're quite a bit cheaper nowadays). Thanks much.
