    What joy filled my heart when I found that Babylonian schoolchildren were likely exposed to "square of the hypotenuse" over 3,000 years before I was! Coincidentally, I bought a math history book intended for children today -- it suits my math knowledge. Turns out the Babylonian arithmetic system depended very heavily on squares - and tables of squares. They lacked a regular multiplication system like ours and needed these tables of squares for multiplying numbers, in a manner all their own. That's why so many squares - and so many tables.

    It looks like Necessity is the mother of invention - and she's a real witch, sometimes.

    Good book: 101 Things You Should Know About Math - Sonia Mehta. Well, only 100 more to go, I guess.
