-6s^2 - 7s/(9s) + 3/s
= (-54s^3)/(9s) - 7s/(9s) + 27/(9s)
=(-54s^3 - 7s + 27)/(9s)

Hi Benjamin;
The concept of positive indices means that the exponentials are positive.
The only negative exponential would be 3s-1.  It is already represented as 3/s.  There is nothing to correct.  However, simplification of (7s/9s) is required.
