Note 1: When writing Roman numerals, the same number cannot be used 4 times in a row. Therefore, the number 4 cannot be written as “IIII”. “IV” is used instead.
Example: The number 30 in Roman numerals is XXX. However, the number 40 cannot be written as “XXXX” as it is against the rules to write the same numbers 4 times. “XL” is used instead.
Note 2: The letter "C" is used to write 100 in Roman Numerals. To write the number 90, X is brought next to this letter.
