Can SS ever have a value less than zero? Solution No, they can never have a value less than 0 for all S = R, where R={1,2,3,4,.......} U {-1,-2,-3,- 4,......} so, SS is always negative for any real number. Positive and negative doesnt matter. As long as S is not an imaginary number like (-3). In which case the answer would be -3.....
