To know whether a a sum is positive, negative or zero with out adding, we use the following formulas :
A number is said to be positive integer if it is greater than zero and a number is said to be negative integer if it is less than zero.
Now,
Positive + Positive = Always Positive
Positive+ Zero = Always Positive
Positive + Negative = positive or zero
Zero + Positive = positive always
Zero + Zero = zero always
Zero + Negative = negative always
Negative + Positive = negative or zero
Negative + Zero = negative always
Negative + Negative = negative always
Hence, in a system where A and B are any two integers then
if A > B, then sign of A determine the Sign of Sum
and if A = -B then answer will be zero
