Roman Arithmetic - a possible New Problem

Dear Clive, Dear Friends, Hi and sorry for my absence during these weeks.

Thanks a lot for the problem, it is live now! I vaguely remember that there exist some subset of problems about deviations from "standard form", perhaps we'll review some of those in future :)

Also have found problem suggestion from Mathias in my mailbox, shall turn to it now. Sorry once more for the delay.

Welcome back Rodion, and thanks Clive!
