Try to rectify a mistake by moving a single matchstick, to get the correct equation.

(Edit: you can not place any matchstick diagonally over the equals sign)

The following equation is made of 11 matches:

XI - V = IV (more solutions)

The following equation is made of 11 matches:

X + V = IV (more solutions)

The following equation is made of 10 matches:

L + L = L (more solutions)

The following equation is made of 12 matches:

VI = IV - III (more solutions)

The following equation is made of 14 matches:

XIV - V = XX

The following equation is made of 11 matches:

IX - IX = V

The following equation is made of 12 matches:

X = VIII - II

The following equation is made of 7 matches:

VII = I

Matchstick Equations - solutionXI - V = IV (more solutions) ... X - VI = IV or XI - V = VI or XI - VI = V

X + V = IV (more solutions) ... IX - V = IV or X - VI = IV

L + L = L (more solutions) ... C - L = L or L + I = LI

VI = IV – III (more solutions) ... VI = IX – III or VI = IV + II

XIV - V = XX ... XV + V = XX

IX - IX = V ... IX - IV = V

X = VIII – II ... X - VIII = II

VII = I ... square root of 1
