Homework Statement

Anyone know any website or link or pdf or ebook which has questions to math topics and offers explanations to them? The book I am currently using has questions but no explanation or answers to the problems and this makes my understanding of topics quite tedious. Is there any weblink of you personally have an ebook or PDF file that has questions and detailed solutions? I desperately need one.
