246. Roman numerals: 10 plus 10 is not equal to 10

Easy Medium Hard Extreme


10 plus 10 is not equal to 10, but move only 2 sticks to make the equation true. Your answer must still be in Roman numerals.

    Depends on your definition of "moving", but you could also do:

    X + I = X I

    Strictly speaking you have to move two sticks: one from the left side of the = to the right side, and the other from a slant to straight up and down.

    Absolutely correct. Your answer is even better than the one above. Thanks!

    Or you can say:

    IX + I = X
