A little math review

For those of you who read my story about numbers and don't really get it here's a little tutorial.

Ex. 6+-5n=56

First add the inverse operation of the number not attached to the variable.
Inverses, plus is minus and multiply is divide and vise vera.
Do it to both sides. PS NEVER DO MATH ON THE COMPUTER!!!!! TOOOO HARD!!!!!

-6 =-6
-5n = 50
---- ---
-5n -5n
n = -10
