I've been googling all over for a solutions manual to the book Basic Mathematics by Serge Lang, but I've only been able to find one for his book on geometry. It's not a terrible problem, but I'm using the book for self-study. At first it seemed that any exercise with multiple parts had at least one part answered in the back, so I could check to make sure my general approach was correct. Now I'm at about the middle of the book, and multiple exercises per section have no answer in the back for any of the parts. Has anyone been able to find one? Should I just feel free to post my attempts at solutions here or perhaps on OpenStudy? I'm working on this book every day and I really don't want to ask constantly for someone more knowledgeable check all of my work for me. I could just trust in my own solutions, but I don't think that's the best idea right now.
