In each of the following three, move a single match to form valid equations. The = and + are composed of two matches each.

1. \/|+|=\/

2. \/|+|=\/|

3. \/|+|=|||

  1. 1) IV + I = V
    2) VI +/- I = V (made the + symbol into a + above the - symbol)
    3) V - II = III

  2. Or make a != symbol out of the equal symbol.

  3. Answers:
    1. \/+|=\/|

    2. \/||-|=\/|

    3. \/| / || = |||
    which comes about by taking the horizontal match of the "+" and using it as a slash and the remaining vertical match forming a 2 with the match to its right.


    Making a not equal sign works, too.

    I'm not sure about the V-|| = ||| I'm just not seeing the one match move?

  4. I know... I tried doing these in my head because i didn't have matches around. So some looked right to me.
