Seems like calculators are making a comeback, though why, I have no idea. Maybe it has something to do with the calculator in your computer and cellphone no longer working in a Mad-Max type future, after a burst of Gamma radiation hits the planet or something…

At any rate, HP wants you to be prepared, going so far as to offer a variety of colors. They’re small enough to fit on a keychain too, so if you have to battle zombies you won’t lose it. Thank God for HP. You’ll be the only survivor who can do math.
