Staff Review
This video goes through the most complicated of all absolute value equation cases -- when there is an absolute value expression on both sides of the equation. The problems done are explained completely and very clearly. This is a great tutorial on more complicated absolute value equations. -

I have enjoyed learning from YourMathGal until the use of 'stuff' and junk for the Absolute Value equations.... just doesn't help the thinking/learning process... using it once or twice for fun is okay - but I'd like to see -in addition- to the 'fun' words samples of what I'd see in a textbook. This would help me organize my thinking...
