This free sample is taken from the complete Algebra book I have uploaded and recently upgraded, which is available for less than US$2. The book contains more than 115 carefully selected questions from the challenging world of Algebra, designed to develop both conceptual understanding and quantitative skill. I have kept the price intentionally low because, despite the considerable time, effort, and care invested in preparing this work, I am currently facing financial strain and personal stress and need to make it available at a price students and teachers can afford. My immediate need is to reach readers while making this work accessible to as many people as possible. I hope this free sample will allow you to see for yourself the level of mathematical depth, quality, and professional care that has gone into the complete book.
