9x =/= 9.
9x= 9* 0.99999999999999999999999999999999999.... which =/= 9, it = 8.99999999999999999999999999999999999999999999.....
however, you are correct, as the difference between 0.99999999999999999999999999999999999..... and 1 is so infintesimaly small it may as well be the same, just like 0.3333333333333333333.... is the same as 1/3, and in this case, 8.99999999999999999999999999999999999999999.... and 9.
fuck, i'm drunk. sue me.
