"twice as many positive integer as n"

doesn't it imply that n is positive integer?
so 2n is divisible by (2 x positive integer n)

never did it say the number of positive integers between 1~n;
if it implies so, shouldn't the statement say 'twice as many positive
integer"s" as n' at least?

i don't know, i might be wrong...

Is the integer n odd?
(1)n is divisible by 3.
(2)2n is divisible by twice as many positive integer as n.
=> 2n is divisible by twice as many positive integers as n is divided by many positive integers

句子被簡化, 我把它還原, 這樣應該句意較清楚
