1st+2nd=3rd (Posted on 2011-09-14) Difficulty: 3 of 5
If we place 192 in the 1st row, 384 in the second row and 576 in the 3rd row, then we get a 3x3 square, exhausting all non-zero digits.
In this square 1st row + 2nd row = 3rd row.

Please provide all other arrangements, satisfying this condition.
