Number System

The Number System forms the foundation of mathematics. Concepts such as divisibility, factors, multiples, remainders and arithmetic operations are built upon a clear understanding of numbers and their properties. A strong foundation in this topic makes it easier to understand many other areas of mathematics. This section is organised into carefully structured topics that explain each concept through clear explanations, step-by-step solved examples, summary tables, common mistakes and practice questions. Explore the topics below to build a solid understanding of the Number System one concept at a time.
