Okay, so I got the puzzle wrong in the previous post. Thanks to olego and delta_mike for catching that. It should actually be:

I + XI = X
Now, what's the fewest number of matches you need to move to make it a valid equation?

Well, I can see how to do it in one step:
Move the 'I' so that it reads "I + X = XI".

One. Take the I away from XI and lay it across the equals sign: I + X =/= X.

I'll offer a different "one". Move the I in XI to the left side, making it I + IX = X... or your previous post.

Zero. Walk around to the other side of the table and look at it again.
