Common Roman Numeral Mistakes

Two rules are often broken by mistake:

• No symbol may be repeated more than three times in a row (so 4 is IV, not IIII).
• V, L, and D (the “five” symbols) are never repeated (so 10 is X, not VV).

Check whether a numeral is written correctly, or find the correct version.
