The following Roman numeral equation is of course incorrect.
Make the equation correct by moving exactly one letter anywhere. You must place that letter in the equation (cannot remove it). You can be creative.
Of course "not equal to" or > or < is not allowed.

To clarify, you mean move a single character (L, I or M) in the equation to a new location in the equation to make it valid. Would moving an I adjacent to another I to make a V or X be valid? Does the construction have to be valid? i.e. IM for 999 is not a valid Roman Numeral. Do you permit it?

I've got a solution.
Take the $M$ and split it up into four parts: one "|", one "", one "/", and another "|".
Next,
Take the "/" and the "", and put them vertically end-to-end above the "$-$" to make an (admittedly shifted) $L$.
This makes
$LI = LIII$ with two lines that we still need to use. Obviously, we throw them on the left side of the equation between the $L$ and the $I$ to get $LIII=LIII$

I've got a solution.
Take the $M$ and split it up into four parts: one "|", one "", one "/", and another "|".
Next,
Take the "/" and the "", and put them vertically end-to-end above the "$-$" to make an (admittedly shifted) $L$.
This makes
$LI = LIII$ with two lines that we still need to use. Obviously, we throw them on the left side of the equation between the $L$ and the $I$ to get $LIII=LIII$

I suppose. @ChrisCudmore he didn't specifically say if it could be broken up or not.

That's really stretching the meaning of "by moving exactly one letter"

To clarify, you mean move a single character (L, I or M) in the equation to a new location in the equation to make it valid. Would moving an I adjacent to another I to make a V or X be valid? Does the construction have to be valid? i.e. IM for 999 is not a valid Roman Numeral. Do you permit it?

Any single letter needs to be moved. The lateral thinking is "V" in "M " is also a letter.
