Pre-Algebra is a fundamental phase of learning mathematical concepts before advancing to higher levels of Algebra. Students usually begin learning Pre-Algebra in middle school, where they acquire algebraic concepts like fractions, decimals, percents, negative numbers, and equations solving. The term Pre-Algebra has various synonyms that can be used interchangeably, such as Elementary Algebra, Introductory Algebra, or Basic Algebra. These terms describe the same mathematical concepts and skills that students learn in the initial phase of Algebra. In essence, Pre-Algebra prepares students for more advanced algebraic concepts like Quadratic Equations, Linear Functions, and Polynomial expressions, among others.
