Putting a (+) and (-) sign together is confusing.
Is this supposed to be:
.
|%28-7%29±abs%289%2B%28-4%2B%28-8%29%29%29|
=|%28-7%29±abs%289%2B%28-12%29%29%29|
=|%28-7%29±abs%28-3%29%29%29|
=|%28-7%29±3|
=abs%28-4%29 OR abs%28-10%29
=4 OR 10
.
-OR-
.
abs%28%28-7%29%2B%28-abs%289%2B%28-4%2B%28-8%29%29%29%29%29
=abs%28-7-+abs%289-12%29%29
=abs%28-7-3%29
=abs%28-10%29
=10
