Fix This Roman Numeral Equation

This Roman numeral equation is wrong, but you can fix it without changing any of the elements of the equation. How is this possible?

I + XI = X

Look at it upside down. Instead of changing the equation, you can change your perspective.

This is from Dan Brown’s novel, Origin.

Nice one — great one actually — but misleading because it says “fix it.” It should say “it is still right” or something like that.
