What? Oh, come on that's totally close enough. It's not even a stretch to accept square + circle = cylinder. Given the basis for all these other "formulas," if those work, this one works too. While I wouldn't call any of them deep mathematical truths, they do form a coherent working concept. -- - |) () /\/ also a math major and very pragmatic
