Obligatory Douglas Adams Note:

As revealed to Arthur through the Scrabble tiles in Life, the Universe, and Everything, the Ultimate Question is "What do you get if you multiply six by nine?" Those of us steeped in basic arithmetic since an early age, of course, dismiss this out of hand without thinking too hard about it.

However, I'd like to point out that it works if you do the math in base 13, which is somehow quite appropriate.

Farewell, Mr. Adams. I already miss the works you'd yet to make.
