Suppose that I give an answer to a question and I get 2 upvotes and 2 downvotes. The reputation of that answer is supposed to be 16 ( 10x2 - 2x2 ). If you look at the question you will just see 0 as the numbers of upvotes/downvotes, giving the impression that the question has never received an upvote or an downvote. Is there a way to know the number of downvotes and upvotes to deduct the reputation of the answer?
We already have this feature. That is a privilege to see the vote count of the post named established user. You need 1000 reputation to gain that privilege. You already have that privilege in Stack Overflow.
You can see the actual votes by clicking on the score. See the privilege page to see how does it work.
