Hello, I have the TI-84+ Silver Edition. Is there a way I can copy numbers from earlier to paste into newer calculations? I have a Texas Instruments TI-30XS and I can scroll back on the display to copy and paste anything at any time. I'm hoping I can do the same with my TI-84+ Silver Edition. When I am doing a series of calculations I need to reuse numbers from earlier calculations, but I don’t want to keep writing down the numbers to re-enter them again later. I also have the TI-89 Titanium, Voyage 200 and TI-89 so I will take any advice you have on any of them to help me copy and paste but I'm most interested in my TI-84+ Silver Edition. Thanks indeed!
