Math is a subject that you must learn to master the techniques of the content before mastering the content itself. Working through the examples written out in a textbook can act as a guide in assisting you with your homework problems. Typically speaking, homework is set up similar to the examples worked out by the author of the book. You could also use the answers in the back of the book as an additional in text guide by working out those problems where the solutions are given, even though they might not be part of the homework problems. It is important to understand each step and go at your own pace. Good luck!
