The Algebra of U

In Facebook I set my status as "F O G" to match my weather.

A friend responded "= F U N"

I saw a chance to do some algebra, and responded:

Algebra Time

F O G = F U N

F's cancel
O G = U N

Divide by N

O G / N = U

To which another friend responded:

F O O D = Y U M M Y!!!

hahahahahahahaha

So, back for some more algebra, I solved for U again with this response:

This one is for all the cannibals out there:

Solve for U

F O O D = Y U M M Y

Divide each side of the equation by M Y squared

F O O D / (M Y)² = U

So that is a square(d) meal deal
