Define Girls = Evil Meaning

My grade 10 math teacher gave us this exquasion in class, very funny, but it all makes sense:

Girls Need Time and Money- Girls = Money x Time
Some people say time IS money- Girls = Money x Money

so right now Girls = Money2 (squared)

People say money is the ROOT of all EVIL

if you sqaure root a number squared it cancels everything out so you just have the word evil.
