yea thanks, i see how it works when i convert it to decimal then back, i.e. base 6 = ...36,6,1 as opposed to decimal = 1000,100,10,1 but the question requires it to be done with a certain method, you don't get marks for converting to decimal then doing the subtraction then converting to base 6 again.

Do any of you know a method like this?
