Magic 46 (Posted on 2011-11-03) Difficulty: 2 of 5
When the below magic square has been completed, each row and each column will add up to 46, as will each of the two main diagonals. The total of the four corners will also be 46 and each of the nine 2x2 subsquares will add up to 46 as well.

Complete the magic square.

Hints/Tips too easy Comment 2 of 2 |
I wont bother actually finding the numbers as the square is perfectly determined by the numbers given.

There is a 2x2 square with 3 numbers: 8, 14, 13 which determines the 4th.

Then you can get the 2x2 square directly below it,
the 3rd and 4th columns,
the 4th row,
the / diagonal,
the center 2x2 square,
the 2nd column and the 2nd and 3rd row,
and the first row/column
