@5fa039c3 move the bottom left match in the eight (making it a nine) and then laying it diagonally over the equals sign. 

 @5fa039c3 

Before: 8 + 3 - 4 = 0
After:  8 - 3 - 4 ≠ 0 

 @5fa039c3 shit, top right stick of the eight, making it a six, and moving it to the top of the four making it a nine.

ok two answers, one is the smart ass way LOL 

 @5fa039c3 moved the stick that made the horizontal part of the 4 to be 11.

8+3-11=0 

 @5fa039c3 

Make the 8 into a 9 and the 0 into a 8:

9+3-4=8 

 @5fa039c3 take the stick from the 8 making it a 6 move that stick on the 4 making it a nine 

 @5fa039c3 6+3-9=0 

 @5fa039c3 

Just how many homemade geniuses do we have in the Gitmo Nation anyway??😂 😂 

 @5fa039c3 9+3-4=8 

 @5fa039c3 8to6 4to9  took me longer than I expected 

 @5fa039c3 In the name of overthinking I made a graph of possible transforms.
