The objective of pre-algebra is to prepare students for the study of algebra. Topics in pre-algebra include operations on real numbers; simplifying expressions; solving first-degree equations, inequalities and application problems; graphing linear equations; simplifying exponents; operations on polynomials; and factoring polynomials.

• Book: Prealgebra (OpenStax)
Prealgebra is designed to meet scope and sequence requirements for a one-semester prealgebra course. The text introduces the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics.
• Book: Prealgebra (Arnold)
This text addresses the fundamentals of arithmetic operations with signed number, including fractions and decimals as well as an introduction to signed numbers, including fractions and decimals as an introduction to some elementary topics in beginning algebra. Topics also include ratios and proportions, perfect squares and their square roots, elementary topics in geometry, systems of measurement, and monomial arithmetic.
