The Roman Numeral, as far as we know, was the only written numbering system used in Ancient Rome and Europe until about 900 AD, when the Arabic Numbering System, which was originated by the Hindu's, came into use. (The Arabic Numbers are the ones we use today 0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
Roman Numerals do not have a zero (0) and have 7 digits (I, V, X, L, C, M)
In our number system, Arabic numbers, we have ten digits (from 0-9) and we can make as big a number as we want with these.
