Answer 4

A. is positive because when you use -(-) the negative becomes a positive, so it will actually be 7 1/2 + 3 1/4.
B is positive, because when you take -3.6 from -2 you get 1.6. -> when you use -(-) the negative becomes a positive.
C is negative because the result will be -2.4.
D is negative because when you take a positive from a negative the answer keeps being a negative, so it will be -7.3.
