Neat! Nice variation. I do believe it is -2 to 2 and the solution would be:
0-2-112
-2-1021
-112-20
12-20-1
201-1-2

Just wonder how you're going to adjust the input so it accepts negative cells.

The introduction of new operations is always welcome, increasing the diversity of puzzles. After some experience with 5x5's or 6x6's, it would be interesting to introduce them in higher puzzles like 8x8 or 9x9 ...

Sneaklyfox: am not sure how on the left side of 2nd row, how -2 -1 = -1
or how you do the right hand corner -2 horizontal solution or the vertical -1 solution?
