The Natural Number System

The natural number system consists of positive counting numbers used for basic counting and ordering, starting from 1, then 2, 3, and so on, extending infinitely. These numbers are fundamental for quantifying objects, measuring, and ranking. Sometimes, zero is included, especially in mathematics, where it represents a null quantity or starting point. Natural numbers form the foundation for more complex number systems, such as integers, fractions, and real numbers. They are essential in everyday life for counting, tallying, and organizing information.
