How many three-digit numbers are divisible by $ 11 $?
Attemp: The list goes 110,121,132....990.
That's just 10,11,12...90.
Subtract 9 from the list, we get 81.
Answer should be $\boxed{81}$
Correct?

As already stated in a comment, this is correct.
(Since I've twice now received delete votes for such answers, I might add that I'm writing this as a community wiki post so that the question doesn't remain unanswered, clogging the system, as there's nothing more to say beyond what's already been said in the comments.)
