Your explanation wasnt too complicated jrandom.... For those that reckoned it got it wrong would you mind posting your original number up and the jumbled as well?

That's really clever. I can remember how we were taught rules to determine if something was evenly divisible by all numbers ranging from 1 (doh) to 9.
Interesting how the cross-sum rule can be used here...
[NERDMODE]
Any integer can be expressed as X=A*9+B, B being an interger between 0 and 9. If two numbers have an identical cross-sum(i.e. have the same numbers in them) they'll belong to the system described by one given B. If you take the difference between such numbers they will indeed always be evenly divisible by 9 since: Y=X2-X1=(A2*9+B2)-(A1*9+B1)=(A2-A1)*9, since B1=B2...
Apply the same rules to the taking one number out and remember that the cross-sum has to be 9 if the interger is to belong to the series of numbers given by X=A*9.

It is preferential to refrain from the utilisation of grandiose verbiage in the circumstance that your intellectualisation can be expressed using comparatively simplistic lexicological entities. (...such as the word fuck.)
