The idea for this book came from my experiences as a finance instructor and tutor. Repeated observations of learners and areas where they struggle, ask for clarification, or request assistance working problems has led me to the main items I cover in this book. This is meant not to be an introduction to finance text but instead a guidebook that addresses the most common questions and areas of concern. It can be used as a supplement while taking an introduction to finance course or it can be reviewed prior to taking a course. A few individuals interviewed as part of preparation for this text also noted how it serves as a useful review for those who have completed the course in the past (new graduate students, for instance, in an MBA program).
