The New York Times bestselling math workbook 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.
