Why are Roman numerals not commonly used in writing numbers like the Hindu-Arabic numerals?
Answer
The correct answer is A: The Roman numerals do not employ place value, so calculations are difficult to perform using these numerals.. The Hindu-Arabic numeral system uses place value (positional notation), where the position of a digit determines its value. This makes arithmetic operations like addition, subtraction, multiplication, and division relatively easy.

Explanation
The Hindu-Arabic numeral system uses place value (positional notation), where the position of a digit determines its value. This makes arithmetic operations like addition, subtraction, multiplication, and division relatively easy. Roman numerals lack place value, making calculations cumbersome - try multiplying XLVII by XIX without converting to Arabic numerals. This is the primary reason Hindu-Arabic numerals replaced Roman numerals globally.
