I have no idea why this question here
has been downvoted in spite of many people answering it and I gave the answer myself got upvotes too but for some weird reason I got downvotes and I can't even ask on Mathematics section of Stack Exchange. Please see for yourself and if you find the question appropriate and inside the guidelines of the site, which it is please upvote it so that I can ask more questions on here. Thanks in advance!
No question in my account is on suspension and no question is on on hold. So I don't know why I'm not allowed to ask. Stack Exchange would certainly not disallow me to ask questions due to just two downvotes.
