Post rules concerning positioning
i am trying to find any rules about the position of numbers but cant find any.

is the order in which they stand in any way important?

example is the 5*5 negative from 10/4
numbers range from -2 to 2
a certain space is a 3- with 2 possible fields
so the solutions can be (2 and -1) OR (1 and -2)
but seeing as how in standard math the position of these numbers is pretty important, does this also translate to the sudoku?

The definition is that:

an ordering exists for which the numbers in the cells,
with the operator applied, produce the target result.

So in a puzzle with available numbers [-2, -1, 0, 1, 2], and the clue 3-
in a cage of 2 cells, possible solutions are

1 - (-2)

and

2 - (-1)
