My brother brought something to my attention earlier this morning and I cannot find the answer with just a googling to end the argument, so I have come to you to ask and understand.

(0! 0! 0!) = n

He says that n is 6. I say that n is 1.

My reasoning: 0!=1 so 1x1x1=1

His reasoning: He won't explain it because he doesn't want to argue about it anymore, but he did mention something about absolute value, which didn't make sense because I saw no || anywhere in the equation.

I don't care who's right. I just want to know what the right answer is and how this equation is solved.

UPDATE:
So, since I spoke to him and showed him what all of you said, he said that the equation was actually (0!+0!+0!)!=6, which means that what was written on the piece of paper that he had given me was written in error.


Question: How many connections reads queue
Answer: Sort of. You can see though sys.dm_exec_requests executing a RECEIVE statement (including a WAITFOR RECEIVE). By simply peeking into the the currently executing text sys.dm_exec_sql_text(sql_handle) between the statement_start_offset and statement_end_offset you can see if the statement is RECEIVE or not (with some parsing...). Figuring out if an active transaction has issued a RECEIVE and is now processing returned messages is more complicated. 

Is somehow of an unusual request, why do you need to know?
