Number Theory (Dover Books on Mathematics) Paperback – 12 October 1994

Really a great book, consider theory plus many problems, but if you are just starting then don't go and try to solve everything from this book, as Many as you can solve,cuz more you do the more you will get familiar with the patterns and then you will be able to solve the problem you left. And I will also sujest that see some vedios of number theory in YouTube before buying, then you will not feel disheartened or unconfident.Happy solving.

Its great book and very helpful

Just a reference book, not a classic. Price high.
