Hello, more than help with a problem I want to ask you if you could recommend me a good book on Number Theory. I'm looking for book easy to follow for a beginner. Thanks.
As someone who really does not ever do number theory this may be a useless.
This is lovely basic book: Discovering Number Theory by Maxfield and Maxfield.
[Disclaimer: I know the authors, man & wife].
Still, it is basic and readable.
