The Ultimate Math Paradox: Why Is $0^0$ Equal to 1 (Most of the Time)?

Ask a room full of mathematicians, computer scientists, and high school students what $0^0$ (zero to the power of zero) equals, and you might just start a heated debate. Punch it into different calculators, and you might even get different answers: some say 1, some say undefined, and older models might flash an error.
