What can Dwight teach us about the signs of products/quotients?

You've probably heard it a million times.
A positive times a positive is a positive
A negative times a positive is a negative
A positive times a negative is a negative
A negative times a negative is a positive.

You've probably even used the little tic-tac-toe chart to remember.

Well here is another one to add to your already long list. I got this idea from a friend of mine, Ms.Goebel, Math teacher at Murrow HS.
Think of the positive sign as love and think of the negative sign as hate.

If someone loves to love that's a positive thing (So a positive times a positive is a positive)
If someone loves to hate that's a negative thing (So a positive times a negative is a negative)
If someone hates to love that's a negative thing (So a negative times a positive is a negative)
If someone hates to hate that's a positive thing (So a negative times a negative is a positive)

If that one doesn't do it for you try looking at it like this:
A positive sign is a friend and a negative sign is an enemy.
A friend of your friend is your friend (So a positive times a positive is a positive)
A friend of your enemy is your enemy (So a positive times a negative is a negative)
An enemy of your friend is your enemy (So a negative times a positive is a negative)
An enemy of your enemy is your friend (So a negative times a negative is a negative)

Just ask Dwight from the office he'll tell you all about it... check out the video below.
