Answer:
Distance from zero.
Explanation:
a good example would be this:
the absolute value of -8 is +8 because -8 is 8 units from zero on the number line.
with everything else, whenever you have a negative number and it's a negative integer, it'll always be negative, and whenever you're trying to switch from positive it'll always be plus.
I hope that makes sense!
Positive integer ( + 5, + 7, + 9 )
negative integers ( - 5, - 7, and - 9 )
