Talk:Brahmagupta-Fibonacci identity

From Wikipedia, the free encyclopedia

It is true this identity can be interpreted using norms for Q(i) but wouldn't it be more simple just to relate to the module property of complex numbers? It would also extend the property to real numbers. Since this identity is, as far as I know, generally used in the context of integer or rational numbers I would keep the norm comment also.Ricardo sandoval 06:41, 8 April 2007 (UTC)
