Make Just One Move
26 - 63 = 1
The above equation is wrong, but can you fix it with just one move?
Hi sunny, the answer is to move the 6 up a little bit, so that you get 2^6 - 63 = 1. Changing the equal sign to not equal works, but you need to say what it is you are moving to create the not equal sign.
Change the 2 into a 7, for instance, and move that line you took out and create a does not equal sign.
