From:
VII = I

To:
II-I = I

This moves two matchsticks (or, if you look at available space, up to 4). You are allowed to move only 1.

However, for the first problem, I tried this:

XI - V = IV to IX - V = IV (you simply move the "I" from after the X to before it, changing 11 to 9.)
L + L = L I also solved as L = L = L

A MESSAGE FOR MANUEL

XI - V = IV answers X-VI=IV

X + V = IV ANSWERS X-VI=IV

L + L = L ANSWERS L+I=L I

VI = IV - III ANSWER VI=IV+II

XIV - V = XX ANSWER XV+V=XX

IX - IX = V ???

X = VIII - II ANSWER X-VIII=II

VII = I ???

L+L=L
remove upright from + and add to first L to make it C for 100-50=50.

[haoleroller]

For the last one how about:

VII>I

[atom_p]

L + L = L (more solutions) ... C - L = L or L + I = LI
?Why C-L=L
how about
L=L=L

IX - IX = V: move slightly one stick from the X to obtain V
IX - IV = V

Actually, it moves one matchstick.

You go from \/|| = | to /|-| = |, and of course the / is really just a | at an angle, so ||-|=|. I don't think the meaning was that you couldn't physically move the matchstick to give yourself enough room, you just couldn't change the formation of the sticks outside of moving the one. Otherwise a lot of them aren't solveable.

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

Here, using your first solution, you moved four sticks, not one. First, you removed the "I" from "XI." Then you moved the "- V" one spot to the left (moving three sticks). Then you put the "I" back after the "- V" (thus moving the fourth stick).

This problem is apparent in each solution.

I have moved just 1 matchstick in each solution ... I will use 1 color for the moved matchstick for each of the 3 possible solutions

puzzle:
XI - V = IV

solution 1: X - VI = IV (from XI - V = IV)
solution 2: XI - V = VI (from XI - V = IV)
solution 3: XI - VI = V (from XI - V = IV)

I advise you post at least 1 puzzle in "new puzzles" section, otherwise your account will be locked

[lambchopx12]

hmmm well is there anything that says you cant multiply because if you can then the last one is easy

From= II-I=I


To= I x I = I
