0.999999(9) = 0.999999(9) 1 = 1 FIRST EDIT: After a lengthy discussion between Borderlinux, GreenFreak and myself, I must concede that I am wrong and they are correct. .99(9) can in fact equal 1. The equation that helped me understand this is as follows: 1/3 + 1/3 + 1/3 = 1 and 9.99(9) is essentially 3.33(3) + 3.33(3) + 3.33(3) so it must equal 1. Good debate. I am not afraid or angered by a good debate as long as some kind of logical resolution can be achieved without people blowing their tops. SECOND EDIT: Ok. I just called and talked to my college math professor. I'm going with what she says cause she's a professional. The professor says: The correct mathematical terminology is that 0.99(9) tends to 1. The key word is "tends to". It means that .99(9) is very close, but can never equal 1. Pretty much "tends to" means that the number is so close that it doesn't make a difference anyway. I'm sticking with the professor.

No. 1 = 1. That is generally the idea of EQUALS, it must be the same mathematical value. Now, if you used an approximate symbol or asked for a limit, that would be true.

if by (9) you mean a way of representing infinitely repeating 9's, then yes. 0.9999999... continuing 9's forever does in fact equal 1.

True: 0.999999(9) ≠ 1 0.999999(9) ≈ 1 False: 0.999999(9) = 1
