-[-2-18]

-[20]

20 correct? these are absolute bars by the way.

No, not correct. |-20| is 20. Put a minus sign in front of it and you have -20. The error is made going from line 2 to line 3.

but absolute is never negative

There is a minus sign OUTSIDE of the absolute value signs. It reverses the sign of the absolute value term, making it negative.

an absolute value can never be negative
