The objective of pre-algebra is to prepare students for the study of algebra. Pre-algebra includes several broad subjects:

• Review of natural number arithmetic
• New types of numbers such as integers, fractions, decimals and negative numbers
• Factorization of natural numbers
• Properties of operations such as associativity and distributivity
• Simple (integer) roots and powers
• Rules of evaluation of expressions, such as operator precedence and use of parentheses
• Basics of equations, including rules for invariant manipulation of equations
• Understanding of variable manipulation
• Manipulation and arithmetic with the standard 4-quadrant Cartesian coordinate plane

• 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.
