Well digit places have to be comma separated i think i told you, in low bases we have unique digits so there is no problems write out numbers without separaation of digitplaces. But when the base is higher than the number of digits you have a choice to make. Either you invent a new numeral(number digit.

I think you realise that BB = 11,11

So your example would of course be ,12345

I hope you see A,B,C,D,E,F is only replacement for 10,11,12,13,14,15
