Roman numeral

[Julene]

[Roman numerals] are numerals that replace the normal Arabic numerals. They use letters such as
I, V, X, L, C, D, and M. Each letter has a value and cannot be repeated more than 3 times. A bar over a [roman numeral] means it has been multiplied [1000] times so you dont have to write numbers that are like 20 numerals long.
