.

If S = (log 1/2) + (log 2/3) + (log 3/4) + ... + (log 998/999) + (log 999/1000),


then  S = .


Now, in the global product, cancel the denominators and numerators in all neighbor fractions, and you will get simple expression


    S = log%28%281%2F1000%29%29 = -3.


THEREFORE, the final   A N S W E R   is  S = -3.

Solved.
