A. Since a negative times a negative is a positive, (-5) (-9) would be 45.

B. 2 - 4 = - 2

C. 12 / (-4) = - 3

D. Adding a negative is essentialy the same thing as subtracting, so - 3 + (-7) is the same thing as - 3 - 7, which equals - 10.

Therefore, the only equation that results in a positive value is A.
