Roman numerals follow specific rules: symbols are generally written from largest to smallest (left to right). Subtraction is used when a smaller symbol appears before a larger one: IV = 4 (5−1), XC = 90 (100−10), CM = 900 (1000−100). Only I, X, C, and M can be repeated (maximum 3 times). V, L, and D can never be repeated. Subtractive notation: only I before V or X, only X before L or C, only C before D or M.

Without vinculum (overlines), the largest standard Roman numeral is MMMCMXCIX = 3,999. Romans rarely needed numbers much larger than this for everyday use. With vinculum notation (overlines multiplying values by 1,000), numbers up to 3,999,999 can be represented. Romans also used dots and other notations for even larger numbers.
No. The Romans had no symbol for zero. The concept of zero as a number was developed in India and transmitted through Arabic mathematics. The Latin word "nulla" (nothing) was used to represent the absence of quantity. This absence of zero limited Roman mathematics — it made complex calculations very difficult compared to the Hindu-Arabic numeral system.
