I had a solution that had bits that incremented and decremented a
roman numeral. That way I could add to or subtract from the first
number while decrementing the second until the second was zero. And so

I think I got to around 220/230 with this method. I don't have it on
me, either, and I think it was a blind alley I went up at one stage,
so I probably won't have submitted it..

But the method to add or subtract directly in RN just seemed far too
complicated to me.
