The equation 1+7=0 was false. However, by moving the matchstick from the top of the 7 and putting it in front of the 1, we get -1+1=0. Rearranging this gives us 0=0, which is true.

Some of you have found an alternative solution and we thank them for sharing it with us. It consists of moving the vertical matchstick from the “+” sign and adding it to the top of the “1” to make it a “7”, thus giving us the following equation: 7-7=0.
