Moving only one element, make the following expression true:

DX = IX

Adding one element, make the following expression true:

IX = VI

In both cases exclude the obvious method of transforming the equal sign into the inequality sign.

Good try LIS, but I wrote moving, not removing

Are you allowed to introduce other mathematical operators? Otherwise I don't see how the statement could ever be true with a D on only one side.

You're not allowed to introduce other math operators. But please consider the meaning of the Hint.

I understand your point, you may be right, but your solution is not in accordance with the given hint.

Well I've been considering away for a good 20 minutes now, and you've got me stumped. I concluded that there must be something more to it than just roman numeral math, since there aren't any standard solutions to the problems, as far as I can tell (there's really only one right way to write any given roman numeral, so no matter how you rearranged the figures, it would be impossible to end up with a correct solution, if that's all this is to it). Besides, your hint suggests something more outside the box in nature anyhow. So, I've been playing with measurement and monetary conversions used in France, Italy, the UK, and the U.S., to no avail. I tried time zone conversions, since one might argue that 500=100 if you look at the numbers as indicators of time, but I still can't make anything work out of that. Hopefully, if nobody figures it out in the next day, you can provide a bit more revealing clue.
