Book/Books on elementary number theory

[Mastermind01]

Hello all,

I probably should have posted this in a math forum but I don't know of any. Can anyone recommend a book/books on elementary number theory with exercises? My math background is not very strong with very little knowledge of set theory so it should be understood by me. We're covering things like Euclid's division lemma, congruence modulo, Fundamental theorem of arithmetic among others...

Thanks in advance..

This seems exactly what you're looking for: https://www.amazon.com/dp/0486474178/?tag=pfamazon01-20 Very short chapters, but it covers plenty of material. Very, very, very good exercises. Low price. One of the best introduction books on abstract algebra out there (and yes, it covers the appropriate number theory).

Hardy and Wright (sixth edition is the newest one; and more complete it covers eliptic curves and so on and has more up to date references).
