The listing, TI 85 graphing calculator has ended.
Graphing calculator with manual. Got this on here, actually, and there is no problem with it, we just ended up getting a Casio around the same time, and my daughter got used to the features on it and didn't want to take the time to figure out the functions on this one :(. GIN will receive a package of two backup batteries (cost 6$ ish). This uses regular batteries, but I guess that backup is just so if you run out of power unexpectedly, it will still function a little longer! :)
