Why is 'x' the symbol for an unknown?

[Noon_waalqalami]

Interesting information not only for math also language history...

[imrankhawaja]

its also interesting with respect to the outcomes of choices we made...

X

suppose you are in the middle of X and there are actually four destinations with four outcomes..

wrong choice= wrong result
wrong choice = right result

right choice = right result
right choice = wrong result..

exactly a mystery thats why we have planet x, we have agent x, we have x GF lol (height of mystery) , we have X rays=>mystery finding rays..

in media we also have X files ,x factor,x men, xxx(vindiesel), and something aham ( hmm) ...also have x ratings lol

we have strange phenomenon like when we multiply we use X when we have to cancel we also use X lol

even we have x word puzzles in games..

That was funny. Thanks for sharing. We should also remember what Mr math has been going through for centuries.
He needs to now face the truth.
