I have the following magic square but cannot determine how the square is actually "magic".
It's a 3x3 as seen below in red with the green showing a few examples of row sums.
Each vertical and horizontal multiplication, for example AxBxC = 120, however, the diagonals do not.
The square of numbers at hand is not a magic square but a multiplicative semimagic square.
In the common definition of a magic square, we demand:
If we replace sum by product, it will be called a multiplicative magic square.
If one relax the constraint and the sum/product only require to be the same along rows and columns, it becomes a semimagic square.
