At a Glance - Sets, Functions, and Relations

"Sets, relations, and functions" doesn't have quite the same ring as "lions, tigers, and bears" (oh my!), but they can seem equally intimidating at times. Except for the fact that they're math concepts, not large animal predators, and you're not in danger of losing a hand if you try to reach out and pet one.

Probably.
