I did another one just like this about an hour ago. I did it the elegant, tedious way,
and it took about 2 feet of screen. Then I realized there was a totally bourgeois but

List all the possible pairs of digits that add up to 9, along with their flips:
18 . . . . . 81
27 . . . . . 72
36 . . . . . 63
45 . . . . . 54

How about 36 and 63 ?
So the original number is 63, and when you flip it, it becomes 36, which is 27 less.
