The | | signs mean absolute value, and go around the parts of the equation like parentheses. As in parentheses, evaluate the insides of the absolute value first.
There are 3 absolute value signs in the equation you gave; I believe you mean |4-|-34||
Evaluate the inner most absolute value signs first, which is |-34|.
The absolute value of |-34| is 34 (always positive).
Now you have |4-34|, having simplified |-34|. Try to evaluate |4-34|
| 4-|-34|??? I know it is absolute value related but i still don't get it!
