Mastering Linear Inequalities: From Foundations to Problem Solving

Linear inequalities are a fundamental pillar of algebra, yet they often cause confusion when moving beyond basic equations. This text-based course demystifies the rules of inequalities, helping you build absolute confidence in your mathematical skills. By the end of this course, you will transition from understanding basic inequality signs to solving complex multi-step problems, representing solutions on number lines, and writing interval notation correctly. What you'll learn: 1. Understand the fundamental properties of inequalities and how they differ from standard equations. 2. Solve multi-step linear inequalities by applying algebraic operations systematically. 3. Graph solution sets accurately on a number line. 4. Write solutions using correct interval notation. 5. Apply inequalities to model and solve real-world word problems. 6. Avoid common pitfalls, such as flipping the inequality sign when multiplying or dividing by negative numbers. The course begins with essential terminology and foundational definitions before guiding you step-by-step through single-variable inequalities, compound inequalities, and practical applications. It is designed for school students, pre-algebra learners, or anyone looking to rebuild their mathematical foundation with no prior experience in inequalities required.
