Developed from Brahmi numerals , the system introduced two revolutionary concepts: positional value (where a digit's value depends on its place) and the symbol for zero as both a placeholder and a number.

The system reached Europe via Spain and was championed by figures like Fibonacci, eventually replacing the more cumbersome Roman numeral system for commerce and mathematics. 2. Regional Variations

Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) are the most common symbols used worldwide to represent numbers in a positional decimal notation system . Despite the name, this system originated in India before being transmitted to the West through the Arab world.

Arab mathematicians like al-Khwārizmī adopted the Indian system, refining it and writing influential treatises that popularized it across the Islamic world.
