Matchstick puzzle with roman numerals
I got a puzzle from a book that asks to move one matchstick to get a valid equation. My "solutions"
feels like cheating... Does anyone have a good idea? The original equation, layed out with matches, is
VI = V + VII
the original picture. Sorry for the low quality

Move the right most I so that it forms a square root sign with the right most V. So it looks something like this: $VI=V+sqrt{1}$
That is a nifty idea.

Something like this:
VII = V | VII (because 7=5|7, using bitwise |)
or:
VI ≠ V + VI

Bitwise or is very clever. The ≠ trick doesn't work because you don't have a valid equation

How about this?
From: the right stroke of the right most V
To: intersect with the I on the right.
Outcome: VI=V+IxI (take x as multiplication sign)
New contributor
These puzzles allow for some lateral thinking, but usually a slanted line cannot be a 1

I also though about something like that. But then the 1 is not really a 1.

How about:
moving the second I in VII so it turns the equal sign equal to a less than or equal sign (VI is less than or equal to V + VI)
2
Then you wouldn't have "a valid equation"!
