Through a convoluted connection, I discovered Longhand, a calculator application for Mac OS X. And by “calculator,” I mean “an application that calculates things,” not “an application that works like a real calculator.” It really is a cool idea: Instead of typing numbers and operations in sequence to get an answer, you type an equation as you would in a word processor, and the result is calculated in real time. Want to change the first operator from a plus to a minus? Just edit it; the result is automatically recalculated. It also supports variables, in case you really want to get complex. I’m going to try it and see how well it works, but so far, it looks pretty powerful.
