About this course

Do you need a strong foundation in high school mathematics, covering the essential principles of algebra and geometry? This course provides a clear, structured text-based guide to reinforce your understanding of core mathematical concepts. By the end of this course, you will be able to confidently approach a wide range of mathematical problems, from solving complex equations to applying geometric theorems. You will gain the critical thinking skills needed to interpret problems and select the most efficient methods for finding solutions, preparing you for academic or professional challenges requiring quantitative reasoning. What you'll learn: * Understand the fundamental laws of algebra, including working with polynomials, exponents, and factoring techniques. * Master techniques for solving linear and quadratic equations, inequalities, and systems of equations using substitution and elimination. * Apply core geometric theorems related to triangles, circles, and quadrilaterals, including calculating area, perimeter, and volume. * Practice quantitative reasoning skills by interpreting word problems and translating real-world scenarios into mathematical models. * Learn the basics of coordinate geometry and introductory trigonometric ratios (sine, cosine, tangent) for right triangles. The course begins by establishing foundational algebraic terminology and manipulation rules before moving into practical applications of equations and inequalities. The final sections focus on building conceptual understanding of Euclidean geometry and applying formulas to solve spatial problems. This course is designed for absolute beginners, students needing a comprehensive refresher, or anyone preparing for standardized examinations requiring quantitative skills. No prior specialized mathematical knowledge is required—just a willingness to read and practice. Start building your essential mathematical foundation today.
