Mathematics · True or False?
The answer is True.
The Roman numeral system is essentially additive (with a few subtractive shortcuts like IV and IX) and completely non-positional: symbols like I (1), V (5), and X (10) keep the same value wherever they stand, so no placeholder digit is needed to mark an empty column the way it is in our Arabic decimal system. The Romans simply had no numeral for nothing. When writers needed the concept, they used the Latin word nulla ("none" or "nothing").
