Yes, changing the forum subdivisions would be nice. Politics and history will get a good discussion, though I don't expect more than 3 topics in the Mathematics section.

.999 =/= 1

As a logical error, only 1 can equal one. Equal means both values are the same (X = X).

Of course, people come up with this by dividing 1 by 3.

1/3 = .333, and multiplying that by 3 is .999, and therefore .999 = 1.

But that is wrong. Simply because 1 cannot be evenly divided by 3. There is still a remainder of .1
