Casio HS-8V Hand-Held Solar Calculator

It's a solar powered calculator that works. Not much else to say. I originally thought it was much bigger, but the dimensions given were "packaged" dimensions. It's maybe an inch bigger than the palm of your hand and fits in your back pocket.

This is a very good calculator. We have two of them at home.... It has the necessary buttons, and others including: MRC, M-, M+, check mark, and a +/- button on the top. The buttons are big enough, and spaced out well, so you shouldn't have a problem with a mess up on your calculator. Even if you do, you can press clear (red button at the top left hand corner) one time, and it won't erase your whole problem. Nice job, Casio.
