Here's the Wikipedia entry for negative infinity: http://en.wikipedia.org/wiki/Negative_infinity

Basically, think number line that extends all the way to the right as far as it can go --infinity--and all the way to the left toward the negative numbers as far as it can go--negative infinity.

Voila!
