. . The answer comes out to:
Question) Evaluate: 522(base 6) - 244 (base 6)
answer = 234 , one mark for both method and answer, no marks given for converting to decimal and back.
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?
