Frequently Asked Questions

Why is the limit 3,999?

Traditional Roman numerals use a horizontal bar (macron) over symbols to represent thousands. Standard notation without special symbols typically ends at MMMCMXCIX (3,999).

How does subtractive notation work?

To avoid having four identical symbols in a row (like IIII), a smaller symbol is placed before a larger one to indicate subtraction (IV = 5 - 1 = 4).

Is there a symbol for Zero?

No. The Romans did not have a numeral for zero; the concept of zero as a placeholder was not part of their system.
