For odd-numbered Magic Squares, we start with the lowest number in the top centre square. If we have a 3X3 square, we start with -4 and end with 4.
Let's refer to the square using a grid with rows A, B, C and columns 1, 2, 3.
Using the up-1 right-1 rule:
Square A2=-4; C3=-3; B1=-2; C1=-1; B2=0; A3=1; B3=2; A1=3; C2=4.

Both of these squares sum to zero horizontally, vertically and diagonally..
