As far as I know, you can't. I know for a fact that those calc can save data... and if you have the cable to plug it into a pc, you can save the file (extension is like .83P or .X83). Those 2 extensions refer to basic programmation for TI. So you have 2 choices: - Convert your .doc or .pdf to a TI-Compatible format (Pretty sure you won't find any app for this) - Write everything yourself into your TI84. It's long... Last thing, I'm pretty sure there's not enough memory in there to store BIG files... TI84 only have 480kb of available space (and 24kbs RAM :lol: )
You cant. Though you should think about getting a TI-89. They're quite useful for calculus and physics and I think you can store basic text files.
