I was looking at a pair of questions:
The rules of Math stackexchange state that a person asking a question should incorporate context in order that the answer be suitable for the person asking mathematical skill etc.
However in this pair of questions we have the same question being asked but clearly a different mathematical background. Indeed it is quite possible that the person asking the first question might not even recognise that the second question is the same.
If context is significant enough that a lack of it can cause a question to be closed or removed then shouldn't questions with significantly different contexts also be considered to be different questions?
