Main prob is how you can describe your moves. Obviously, the idea is to make the equation valid by moving as few matches as poss. If we called the left to right “a” across to “e”, that might help, also top, middle, lower. Let’s see how it unfolds.
Take the top match (horizontal one) on the 7 and move it to the middle.1-2= -1

Comments need a moniker of your choosing before or after ... no moniker, not posted, sorry.
