If the sum is not divisible by 9, you can still use the sum to see how far away the target is from 9. Eg: 622 -> 6 +2 +2 = 10 - not divisible by 9, but just 1 away. So we know 622 -1 is divisible by 9. So 622 -1 = 621. 6 + 2 +1 = 9. (621 / 9 = 69) Ex2 - 754 -> 7 +5 +4 = 16 (Not divisible, but 2 away from 18 which is) so 754 + 2 = 756 (7 + 5+ 6 = 18, divisible by 9. 756 / 9 = 84) ===============
