**Posted In**: Math.

Numbers are part of our everyday lives, yet we don’t really know much about the numbers specifically, choose a number, any number, and ask yourself: “What else is there to know about this number besides the obvious?”. Odds are, you won’t come up with an answer on your own, so don’t kid yourself. But believe it or not, every number has some semblance of a meaning behind them, it’s just hard to find without talking to someone who really, really knows their numbers. But speaking of facts, let’s choose a number right now and answer a few questions… how about the number ten? Seems fair, let’s see what we can find out.
