Matchstick Equations - Back to the Matchstick Puzzles
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

Spoiler for Solution:

Matchstick Equations - solution
XI - 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

What? Confused!

Hah, one thing you could do, is pick up a random match, and place it diagonally over the equals sign. Making the statement read, XI (doesnt equal) X.

1. move the I from XI over to after the V.
XI - V = IV
becomes:
X - VI = IV (10 - 6 = 4)

2. Move the I from the + to make it a -, and move it to after the V.
X + V = IV
becomes:
X - VI = IV (10 - 6 = 4)

Haha. square root of 1. Ha ha

Couldn't L + L = L also be changed with a movement of the plus sign matchstick to be L = L = L

and @ mogul, I thought of that same thing

[twilly]

i say we light all the matches and watch them burn

[nosmofui]

L+L=L

L+I=L I

[MCBergsma]

For the last one, why not
From:
VII = I

To:
II-I = I

?

[tandebauer]

The last one can not be solved
ll-l=l
that moves to many match sticks.
