a) Yes. For Example: if we add the numbers like 1 + 2 we will get the answer 3. So by adding positive integer and a positive integer we get a positive integer.
b) Yes.For example if we add the numbers like -1 + -3, we will get the answer as -4.So adding a negative integer and a negative integer we get a negative integer.
c) Yes. For example if we add 5+ (-3) we will get the answer as 2 and one more example is 7+(-9) we will get the answer as -2. So adding a positive integer and. A negative integer we get the answer as a positive or negative integer.
d) Yes. For example : if we add 6+(-6) we will get the answer as 0. So adding the opposite integers we get the answer 0.
