This book is algebra with a jolt of fresh air and maybe a whiff of a caffeinated beverage. It's a complete algebra learning experience that engages readers by having them play games, solve puzzles, ponder mysteries, learn the fundamentals of Algebra I that current students are struggling with, or parents have long since forgotten. While readers experience the joy of math, they'll learn (almost without noticing) everything they always wanted to know but were afraid to ask about natural numbers, exponents, graphs and graphing, polynomials, factoring, algebraic fractions, solving equations, the quadratic formula, and much more. Like all of the books in our "Head First" series, "Head First Algebra" uses a visually rich format designed for the way the brain works. Based on the latest research in neurobiology, cognitive science, and learning theory, this book combines words and pictures in a playful, mixed-media style that not only helps readers understand a subject, but also to remember it.
