      Aside, quick-tip: If there is a 9 in the problem:

      A number is divisible by 9 if the sum of it's digits is divisible by 9. 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)

      It also works for 3 and 6, if the sum is even then it is divisible by 6, the more you know!

      Hard luck on my puzzle. Im afraid I only had a single 6 in it. Here is another way around it:

      7*8=56+2 = 58*(7+6) =754

      8*5 = 40+7 = 47*10 = 470+5+3 = 478
