  1. 4 = 5 - 1 is also an answer

    1. So what you suggest is make the minus sign an equal sign. That's 1 move. How do you then change the "4" into a "5"? You need 1 extra matchstick...

  2. 1-1=0 is also possible, almost the same

    1. Nope... the instruction says move 3 and not 4 as in your solution.
