\(Is |a|>|b|?\)
so we are looking for whether a is farther away from 0 or b is farther away from 0.
1) \(a+b<-(a+b)\)...2(a+b)<0...we cannot say anything.
2) \(a>b\)...both are of same sign, we can answer yes or no, otherwise not possible to answer.Both positive |a|>|b|, and if both negative |a|<|b|

Combined...a+b<0...
If a>0, b has to be negative and |b|>|a|.
If a<0, b also will be negative, and if both are negative we know |B|>|a|, since a>b..
In both cases answer is NO..
Sufficient
