Books of algebraic number theory

Question

I am learning algebraic number theory, the exercises are so hard for me, could you please recommend me a book with answers? Many thanks!

Answer 1

Reid's book from 1910(-ish) gives a very slow introduction. I don't think it has answers, but it has almost everything worked out in the text. If you don't mind the stilted, 100-year-old language, you mind find it useful. I see it's on Amazon:

https://www.amazon.com/Elements-Theory-Algebraic-Numbers/dp/1110380461

But I know there are scans of it online.

Answer 2

Murty & Esmonde's Problems in Algebraic Number Theory (available here as a pdf) is an excellent source of problems with solutions. However, as someone pointed out in the comments, looking up a solution to a problem is helpful only after you have worked on it yourself for a sufficient amount of time.
