294. Mathematical: Move 1 and remove 1

Easy Medium Hard Extreme


The equation is not true, but by moving only 1 matchstick (from the "+" sign) you get 7-1=6 which makes the equation true.

This is easy, but can you MOVE 1 and REMOVE 1 to come up with a different answer?

    Couldn't you also move the top left matchstick from the six to the top right and remove the bottom right matchstick from the six to create another true equation: 1+1=2
