Ah, I see we're still doing the "top dismissive comment" thing around here. Good to know. Computers? Bah! We've been "computing" for centuries. How does it work? You take a pencil and paper -- or a pen (should you be feeling bold), and you write out the computations one by one, and build up a result that way. Pythagoras managed to compute that the square of the hypotenuse is equal to the sum of the squares of the other two sides, and that rule still stands.
