Absolute Value

Son2 is a bit stuck on this:

(4-10)^2 + 3^2 -|5[-4(1+2)]^2|

 (^ means to the power of and | is the absolute value symbol)

Any thoughts much appreciated.

Oh, I didn't look at this post first - I was thinking you just meant the concept. To which I was going to say I absolutely don't want to lose the value of the negative balance I have on my statement from paying early.
I know the absolute value signs do not work like a parantheses. Does this site help http://www.purplemath.com/modules/absolute.htm?
