There was an internet meme started last year about ambiguously written arithmetical expressions leading to arguments for different possible values. Of course this is not a good place to host pointless arguments, but this is a place where people can be directed to definitive confirmation of the ambiguity of such expressions as $48/2(9+3)$, with the highest voted answer to this post from April last year being a good example.
Yesterday a duplicate was asked, and it was closed as a duplicate. However, it was closed as a duplicate of a question that is also closed, so this does not leave a place to post an answer.
I am in favor of reopening the older version, What is 48÷2(9+3)?, and have cast a vote to do so. I think that "protecting" the question to block new users from answering is a good idea.
If you think that the question should be closed, why?
Incidentally, I had voted to close the older question, but if I remember correctly, I voted to close it as a duplicate of an even older question which I had answered, but instead the older question was merged into the newer one. Regardless, I am now in favor of reopening.
