A Number Square is a 4x4 arrangement with a different number 015 in
each cell. For example, a Number Square could be:
1 12 3 2
9 8 13 7
4 15 0 11
10 14 6 5
Given the clues below, can you determine the composition of Number
Square 2?
 On the upperleft to lowerright diagonal, the upper left number minus
the number next to it down the diagonal equals 14; the lower right number
on the upperleft to lowerright diagonal minus the number next to it
up the diagonal also equals 14.
 The entry in col. 2, row 3 minus the number in col. 1, row 3 equals 7.
 The number in col. 1, row 3 minus the value in col. 1 row 4 gives 1.
 The four numbers down the leftmost column of the square add to 34.
 The sum of the four numbers in row 3 of Number Square 2 equals 24.
 Adding the four bottomrow numbers equals 37.
 Subtracting the number in col. 2, row 4 from the number in col. 3, row 4
leaves 1.
 The number in col. 3, row 1 less the number in col. 4, row 1 equals 4.
 Taking the entry in col. 4, row 2 from the value in col. 2, row 1 gives 5.
