Who uses this concept?
I don't think that it is correct that anyone calls a proof "elementary" just because it does not use the square root of (-1). Nor is it true that an elementary proof is necessarily preferred.
It is not an assumption that (-1) can have a square root. It can be proved. Nor is the square root unique. (-1) has 2 square roots, if it has any.
I suggest killing this article. It just isn't useful. RSchlafly 00:11, 5 February 2007 (EST)
