X-l=l (or 10-1=1)
Your task: Move one match to fix the equation.
You may not stack, break, or remove any matches.

Nice. An alternate solution is to move the negative sign to a diagonal slash through the equal sign, giving the roman numeral statement XI not equal I.
Ah, you may not stack. Sorry. Well done!
Thanks!
Although I should add for future teasers that you can't make a not equal sign.

I think you were good. The not-equal requires matches be stacked, which you addressed. I just got it wrong.
This may be an alternative solution that meets the requirements...
XI = 11
I really like the way the given answer reinterprets the X from ten to multiplication. This is a fun puzzle.

Ha, I came up with the same solution as you snow. XI = 11
This was clever, KD. Well done
