* Mathematics: For calculations, equations, and representing quantities.
* Science: In scientific notation, measurements, and data analysis.
* Technology: In computers, programming languages, and digital displays.
* Everyday Life: On clocks, money, calendars, addresses, and basically any time we need to express a number.
The Hindu-Arabic system is so widely adopted because it's:
* Efficient: It uses only ten symbols (0-9) to represent any number.
* Flexible: It can easily represent large and small numbers, fractions, and decimals.
* Versatile: It can be adapted for different languages and cultures.
While other numeral systems exist (like Roman numerals), the Hindu-Arabic system is the dominant and universal choice due to its practicality and ease of use.
