Question 4 What other operations can be performed on a magic square to yield another magic square? Besides adding a constant or multiplying by a constant, you can also: Subtract a constant from every number. Divide every number by a constant (if they are all divisible). Rotate the square by 90°, 180°, or 270°. Reflect (flip) the square horizontally or vertically. Any combination of these operations (e.g., doubling every number and then subtracting 1) will also result in a magic square.
