Answer 1

Arabic numerals replaced Roman numerals primarily because they made it easier to perform calculations. The place value system of Arabic numerals, along with the concept of zero, allowed for more efficient arithmetic operations compared to the additive and subtractive nature of Roman numerals. This made calculations quicker and less prone to error. Additionally, Arabic numerals are generally easier to read and write, further contributing to their adoption.
