Zero is so awesome. For example, it's the only number that it's own vector space. That's totally sexy. And another thing, every vector space must include "the zero vector" (which is usually zero, or some variation of it; i.e. 0 in R² = (0,0)T); otherwise the basic algebries will cease to function properly. Zero, by far, is a very important concept/number. ^_~
I did the test and only got π; then again, that is one of my nicknames.
