They made it easier to perform calculations
They were easier to read
The correct answer is: They made it easier to perform calculations.
Arabic numerals, also known as Hindu-Arabic numerals, replaced Roman numerals because they introduced a place-value decimal system, making mathematical calculations much simpler and more efficient. Unlike Roman numerals, which involved complex combinations of letters to represent numbers, Arabic numerals used a limited set of digits (0-9) and the concept of positional notation, where the value of a digit depends on its position within a number. This revolutionary mathematical system facilitated faster and more accurate calculations, leading to their widespread adoption.
