Take any 3-digit number in which the first and last digits differ by 2 or more. Reverse the number, and subtract the smaller of the two numbers from the larger. Then reverse the result and add up these two numbers. The result will always be 1089.

Example: 401-104=297. 297+792=1089.

abc = 100a + 10b + c
cba = 100c + 10b + a

abc - cba = 100(a - c) + (c - a) = 99(a - c)

Possible answers (def), excluding 99: 198, 297, 396, 495, 594, 693, 792, 891

198 = Reverse(891)
297 = Reverse(792)
396 = Reverse (693)
495 = Reverse(594)

d + f = 9
e = 9

def + fed = (9 * 100) + ((9 + 9) * 10) + (9 * 1) = 1089
