I think that the answer is a increase
It seems okay to me (if that what your asking) I don't know this subject very well ut the part your working on " I'm familiar with ?" Don't be surprised if I was wrong buuuuut it does look okay to me "(the answer)".

This would be something like [5] or -[-5] which is absolute value (>.<)
