Can you solve this?
5 - 7 = -2
Move the vertical in the + to make it 5-7 not equal 2.
5-7=-2
9 - 7 =2
Moving just *one* matchstick *without* changing the tracking or kerning? Is that what the challenge is?? In that case... ..... .... ... .. . . . . 9-7=2
The top of the seven to make the 2 into a 6 which makes the equation: 5 + 1 = 6
5-7=-2
Move the up-down stick on plus sign top right empty slot on the first numeral to make it a 9. Then you have 9-7 =2
