I know a similar question has already been asked, but can anyone suggest a good book on mathematical logic that includes answers to exercises? I am looking for something that is conducive to self-study and knowing if I'm right or wrong with the exercises is very important to me. Thanks for any input.
I picked Chiswell and Hodges "Introduction to Mathematical Logic" which I found in Peter Smith's guide and I personally regard it as one of the best mathematical book I have ever read. It has a lot of exercises many of them have full solutions. I am also self learner and I know how important are exercises with at least answers if not full solutions.
