What is the biggest difference between Roman Numerals and Hindu Arabic Numerals?
Second, Hindu-Arabic numerals include a symbol for zero, while the Roman system completely lacks that. The zero is used as a place holder in such numbers as 1028, indicating one thousand, no hundreds, two tens and eight singles. This place holder allows aligning of several numbers and makes addition and subtraction easier, and multiplication and division so much easier that calculations can be done with Hindu numerals that are simply impossible with Roman numerals.
