Talk:Quadratic residues

I'm sure someone wants to write out all the fun properties of Legendre symbols. It just happens not to be me right now. -- ComplexZeta

Is it any number n, or any integer n? --- cosinator

Where? --ComplexZeta 11:07, 27 June 2006 (EDT)

In the introduction it says 'We say that a is a quadratic residue modulo m if there is some number n so that n^2 − a is divisible by m.' If it were any number, I would think that any a could be a quadratic residue modulo m

Thanks for clarifying -Cosinator
