imo, answer should be 0.

if x*-y = -24

then -x*y is also equal to -24.

for every pair (x,-y) there is a corresponding pair (-x,y)

if x*-y = -24

then -x*y is also equal to -24.

for every pair (x,-y) there is a corresponding pair (-x,y)

I think integers are -24 & 1 such that their product is (-24*1) = -24

and so their sum would be (-24+1) = -23.

so, -23 is correct.

and so their sum would be (-24+1) = -23.

so, -23 is correct.

oopss .. misread the question as "the sum of all integers whose product is -24" ! agree with -23.
