Arabic numerals replaced Roman numerals primarily because they made it easier to perform calculations. The place-value system of Arabic numerals allowed for more straightforward arithmetic operations, such as addition, subtraction, multiplication, and division, especially with the use of zero, which Roman numerals lacked. This efficiency in calculations, along with their simplicity and clarity in notation, contributed significantly to their widespread adoption over Roman numerals. While ease of reading is also a factor, the primary reason is the facilitation of mathematical computations.
