This course is designed for high school students who have a significant weakness in the fundamentals of mathematics and find it difficult to keep up with the current curriculum. We start with them from scratch in basic operations, simplifying expressions, dealing with fractions and roots, This course aims to establish the student in the basics of mathematics from the beginning, in a gradual manner suitable for students who have difficulties with the basic structures of the subject, so that they are prepared to study calculus later with greater confidence. Course content: • Basic operations on numbers (addition/subtraction/multiplication/division) • Simplifying algebraic expressions and analysis Fractions, roots, and exponents Solving linear and quadratic equations Inequalities and their representation • Introduction to functions: domain, range, graphing • Fundamentals of triangles and the trigonometric circle Training mechanism: • Live online explanations through interactive sessions • Immediate exercises during the explanation • Assignments after each meeting + brief correction • Level assessment test at the beginning and end of the course Teaching methods and techniques: • Simplify concepts using real-life examples • Using mind maps and visual organization • Gradual progression from easy to difficult to ensure understanding Expected learning outcomes: Understanding the fundamentals of algebra, functions, and trigonometry • The ability to solve basic problems without confusion • Readiness to enter calculus or higher tracks Target group: High school students who struggle with mathematics and want to build a strong foundation from the start. Prerequisites: There is no — the course starts from scratch
