be forward, think backward

A bit more on the graphing calculator before I go.

I suddenly drew upon a revelatory process. Stick with me.

Bassinet >>>> Baby >>>> Garage sale / eBay / Craigslist

TI-83 >>>> ___________ >>>> ___________

See if you can fill in the blanks.

The more I thought about it the more I realized that a poor college graduate with a TI-83 in the boxes he's moving from his frat house might just want to get some cash. How would they do that? What could they sell?

Trust me when I say that you can type TI-83 into Craiglist anywhere in America and not be disappointed. I'm pretty sure that nothing has changed in the graphing world in the last ten years.
