Create a 4x4 Magic Square where each row, column, and diagonal adds to -7

Answer 1

Explanation:

First, a 4x4 magic square to remind you what it is: 8 11 14 1 13 2 7 12 3 16 9 6 10 5 4 15 Every row, column and the main diagonals add to the same total (here it is 34). What other groups of numbers add to 34? Actually in this example all broken diagonals also add to 34, and indeed 2x2 blocks do too.
