About this course

Are you or your student struggling with the rules for combining positive and negative numbers? Misunderstanding signed numbers is one of the biggest roadblocks in early algebra and foundational mathematics. This course provides a clear, systematic approach to handling signed numbers, ensuring you understand the underlying concepts, not just memorize formulas. By the end, you will confidently perform all four basic arithmetic operations with integers, setting a strong foundation for higher mathematics. What you'll learn: * Understand the concept of signed numbers and their representation on the number line. * Apply the specific rules for adding and subtracting positive and negative integers correctly. * Master the multiplication and division rules for signed numbers, including handling zero and multiple signs. * Practice systematic problem-solving to rapidly increase calculation speed and accuracy. * Learn how to simplify complex arithmetic expressions involving multiple signed operations step-by-step. The course begins with core definitions and conceptual models, progressing through dedicated sections for each operation (addition, subtraction, multiplication, division). We conclude with systematic practice exercises combining all learned concepts. This course is designed for absolute beginners, middle school students, or anyone needing a reliable refresher on foundational arithmetic. No prior knowledge of algebra or advanced math is required.
