Definition: A number represented by a one followed by a hundred zeroes.
[@more@]Usage: It is important when you are balancing your checkbook that you never confuse a googol with a googolplex, a number with a 1 followed by a googol of zeros. It is easy to do, given the similarity in pronunciation and spelling.
Suggested Usage: So, if I'm not a mathematician without enough to occupy my mind, how can I use this word? Funny you should ask. The obvious place is on the invitations to your parties: "Come to our party Saturday night for gaggles of gags and googols of giggles." (That kind of silly hyperbole should hold the attendance to full-time fun-lovers.) If you are totally immune to silly alliteration and hyperbole, you could refer to googols of googly-eyed fans surrounding a rock star. But then most of us wouldn't.
