The numbers 1 through 9 are arranged in a 3 x 3 grid so that each number is in the grid exactly once. They are arranged such that the top row plus the middle row gives the bottom row. If the grid forms another such addition when it is rotated 90 degrees to the left, what is its composition?

(Note: The numbers don't flip, for example 6 doesn't turn into 9.)

(In reply to solution by derek)

I think someone needs to learn how to do math. on the first one 1 + 5 does not equal 7 and on the second 1 + 4 does not equal 6.
