Pre-Algebra is recommended to be the first AoPS Book after the student completes the Beast Academy. The purpose of the book is to serve as an entire Prealgebra course. Students get the problems, and then they have the solutions to all of the problems along with explanations. There are over 1000 questions, and the solutions manual to the exercises/review problems/challenge problems gives explanations, not just answers. Topics in this book include properties of arithmetic, exponents, primes and divisors, fractions, equations and inequalities, decimals, ratios and proportions, unit conversions and rates, percents, square roots, basic geometry (angles, perimeter, area, triangles, and quadrilaterals), statistics, counting and probability, etc.
