I am a freshman in high school I would like to major on physics and most likely in mathematics in college so I figured it would be worthwhile to start learning more math. In school I am currently learning geometry and next year my class will cover Algebra II. I was wondering what would be the best book for me to learn and hopefully master Algebra II. I have heard of Gelfand's book, Algebra. Would that give me a complete understanding of Algebra II or would I need an actually Algebra II text book for understanding Algebra II, if so what would be the best textbook. I would also like to keep the price of the book to around 20 dollars or less.
