This book is intended as a study aid for fundamental algebra. The contents focus mainly on American high school curriculum. But anybody from any part of the world who is willing to learn a little algebra can be benefitted from this book. A big part of this book is focused on state regent exam (New York State). But it would be helpful for any high school student in America. The teachers can find some practice problems. The best part of the book is that there are answer explanations on all problems. This book is the outcome of my long years' experience of teaching and tutoring. Every problem is out of my imagination and creativity. These are not copied from any book or online resources. This book is for all students, teachers, future scientists, and engineers. A good foundation of math is very much necessary for future scientists. So I tried to include as many realistic problems as possible. Thank you all.
