Question

10-12 plz!!!!!!!!!!!!!!!!!!T.T

Answer 1

I'm guessing
(1,1) 1
(2,1) 2
(1,2) 1/2
If that's what it's asking,

Answer 2

-2 It would be a negative since it is a smaller number taking away a larger number and it would be negative 2 because 12-10 is 2 and you would put the negative sign in front of it.
