How are numerical values represented in number representation?

Numerical values are represented through numerals, which are symbols used to express quantities in a standardized way. For example, the numeral "5" directly represents the quantity of five objects. This system allows for clear communication of numerical information across different contexts, such as mathematics, science, and everyday life.

Using numerals is efficient for calculation and comparison because it provides a concise way to represent larger quantities and complex mathematical concepts without ambiguity. Each numeral corresponds directly to a specific value, making it easy to understand and manipulate in mathematical operations.

Other methods of representation, such as visual images, words and definitions, or colors and shapes, may convey concepts related to numbers but do not serve as standardized representations of numerical values in mathematical notation.
