The course begins with a review of real numbers and their properties. Students learn about the different sets of numbers, such as natural numbers, whole numbers, integers, rational numbers, and irrational numbers. They explore concepts like absolute value, inequalities, and properties of exponents. Algebraic expressions, including polynomials and rational expressions, are introduced, and students practice simplifying and evaluating these expressions.

2. Equations and Inequalities

In this section, students delve into solving equations and inequalities. They learn various techniques for solving linear equations, quadratic equations, and systems of linear equations. The course also covers absolute value equations and inequalities, rational equations, and radical equations. Students develop the skills to analyze and solve these equations using algebraic methods.

3. Functions and Graphs

The study of functions and their graphs is a fundamental aspect of algebra. This section introduces students to the concept of a function and explores different types of functions, such as linear, quadratic, exponential, and logarithmic functions. They learn about function notation, domain and range, transformations of functions, and inverse functions. Students also gain proficiency in graphing functions and interpreting graphs to understand real-world situations.

4. Polynomial and Rational Functions

Polynomial and rational functions are essential components of algebraic study. In this segment, students delve into polynomial functions, including their properties, zeros, and factors.
