First, the line that makes you think division means division, pure and simple. I suspect what you are saying is that in arithmetic classes you are expected to get a numeric approximation if a division does not have a neat answer. That is not true in algebra. If you can't get an exact decimal answer in algebra, you should leave the answer in fractional but exact form unless told otherwise. Second, there is no plus or minus sign in front of 1.

Only two real numbers equal their own square root, namely zero and one.
