The classic "pick a number" trick that makes you seem like a mathematical sorcerer. The equation (2x+6)/2 - x = 3 simplifies to 3 for any value of x. It's algebraic sleight of hand - you multiply by 2, add 6, divide by 2, then subtract the original number... and voilà, you always get 3. The character's demonic transformation represents that moment when you realize math isn't just for homework - it's for freaking people out at parties. Mathematicians have been pulling this stunt since Babylonian times, probably.
