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

1) IV + I = V
ReplyDelete2) VI +/- I = V (made the + symbol into a + above the - symbol)
3) V - II = III
Or make a != symbol out of the equal symbol.

I know... I tried doing these in my head because i didn't have matches around. So some looked right to me.
ReplyDeleteOh good... I thought I was missing something obvious.
