1-1= 1-1= 1-2= 1-1= 2 3 3 4

Answer 1

1-1=0 1-2=-1
или ты чтото другое спрашиваешь и причем снизу цифры?

Answer 2

I'm sorry, but the equations you provided do not have consistent or correct answers.

1-1 equals zero, not one. 1-2 equals negative one, not one. 1-1 equals zero, not two. I'm not sure what the numbers 2, 3, 3, 4 are supposed to represent in this context.
