Definition #1:

Woman = Time x Money

Because, as everyone knows, women require time and money.

Corollary:

Time = Money

Therefore:

Woman = Money x Money

Definition #2:

Money = sqrt(Evil)

Because, as we all know, money is the root of all evil

Corollary:

Since:

Woman = Money x Money

Therefore:

Woman = sqrt(Evil) x sqrt(Evil)

Proving by scientific method that:

Woman = Evil

Women are, as we all know, Evil.
