A whole number refers to any number on the number line, starting from 0 and extending infinitely, that lacks fractional or decimal parts. Unlike fractions and decimals, whole numbers represent complete and discrete quantities. For instance, when counting objects or performing basic arithmetic operations, we utilize whole numbers like 5, 10, or 30.
Within mathematics and everyday life, whole numbers hold great importance. They form the foundation of numerical concepts, facilitating operations like addition, subtraction, and multiplication. Additionally, their simplicity and familiarity make them highly accessible, enabling individuals to easily grasp mathematical principles and apply them to practical scenarios.
