여성이 악(惡)임을 증명하라

Proof that girls are evil.

First we state that girl require time and money:
Girls = Time × Money

And as we all know "time is money."
Time = Money

Therefore:
Girls = Money × Money = (Money)2제곱

And because "Money is the root of all evil.":
Money = √evil

Therefore:
Girls = (√evil)2제곱

And we are forced to conclude that:
Girls = Evil
