The New York Times bestseller from actress and math genius Danica McKellar that teaches seventh to ninth grade girls how to conquer pre-algebra Stepping up not only the math but the sass and style, McKellar helps math-phobic teenagers moving up into high school chill out and finally "get" negative numbers, variables, absolute values, exponents, and more. As she did so effectively in Math Doesn't Suck, McKellar uses personality quizzes, reader polls, real-life testimonials, and stories from her own life--in addition to clear instruction, helpful tips, and practice problems--revealing why pre-algebra is easier, more relevant, and more glamorous than girls think.
