A variable is a fundamental concept in mathematics, science, and computer programming. It represents a symbolic or named placeholder for a value that can change or vary.
Variables allow for the storage and manipulation of data in calculations, experiments, and computer algorithms.
They can hold different types of information, such as numbers, text, or complex structures, and their values can be modified during a program’s execution or within a specific context.
Variables play a critical role in modeling and solving problems across various disciplines, facilitating dynamic and adaptable data handling.
