But I got one of these in a cereal box!

Here was have it, the wonder of the ages, a calculator that only costs $345! I wonder what the expensive ones cost. I remember my Dad furiously working at an adding machine, and before that, I guess, we had the abacus. But this one revolutionized everything. You could actually lift it and carry it around (with difficulty). The only calculator I own now is a fridge magnet doubling as a clip to hold papers (usually my grandkids' fingerpainting and stuff). I got it free somewhere from some place that was trying to get rid of them.
