Which statement is true?
A.The sum of two positive integers is sometimes positive, sometimes negative.
B.The sum of two negative integers is always negative.
C.The sum of a positive integer and a negative integer is always positive.
D.The sum of a positive integer and a negative is always negative.
Just wanna make sure, isn't it the answer is D???
(+)X() = always negative

I disagree.

But
A is (+)X(+)=sometimes +/
B is ()X()=always negative
C is (+)X()=always positive
D is (+)X()=always negative
So A,B & C are not true, only I can find the answer is D. No?? 
The sum is the result of addition.
2 + (3) = 5 
Answer is A???

I mean B

B is correct.
