Question 245850
I can't tell when you are using 1 as an absolute value and when you're using it as a number.  
So, I would say to first replace the absolute value symbol |x| for parenthesis and let the inside figure be a positive number.
Then express them without the parenthesis.
Remember to preserve negative signs that are between two sets of absolute values because those do not change to positive.  
Notice I said "between two sets", not "within a set".  Some examples:
.
|-x|-|-x| would equal to (x)-(x) and equal to x-x.
.
|x|-|x| would also equal to (x)-(x) and x-x.
.
|x|+|-x| would equalt to (x)+(x) and x+x.
.
|-x|+|x| would equalt to (x)+(x) and x+x.
.

PS.  Next time please use shift + the third key to the right of letter "P" on your keyboard when expressing absolute values.
