About this course

Understanding how computers process and store data is the cornerstone of computer science and a key requirement for academic exams. This text-based course guides you through the fundamentals of positional number systems, from decimal and binary to octal and hexadecimal. You will transition from manual base conversions to confidently performing arithmetic operations in non-decimal systems, while learning how these concepts apply to modern computing topics like memory representation and bitwise logic. What you'll learn: * Understand the theoretical foundations of positional and non-positional number systems. * Convert numbers seamlessly between binary, octal, decimal, and hexadecimal bases. * Perform addition, subtraction, multiplication, and division in different number systems. * Solve standard computer science exam problems and logical puzzles systematically. * Apply binary concepts to modern computing scenarios like IP addressing and bitwise operations. * Practice your skills with step-by-step written exercises and self-assessment challenges. This course starts with essential terminology and foundational definitions before moving into practical conversion algorithms and arithmetic. Designed for absolute beginners and students preparing for computer science exams, this course requires no prior programming or advanced math experience. Start reading today to master the mathematical foundations of modern computing.
