    It's rather simple, really, if you give it a lot of thought.

    Notice on the grid that all the items that have a number that is a multiple of 9 (i.e., 9, 18, 27, 36...) are the same item. That's because when you take any two digit number and subtract it by each of its digits, you will always get a multiple of nine. A few examples:

    47 - 4 = 41 - 7 = 36 (4 x 9)

    39 - 3 = 36 - 9 = 27 (3 x 9)

    25 - 2 = 23 - 5 = 18 (2 x 9)

    After that, it's just a matter of simple programming.
