Clocks do not always show the number 4 in this way. However, the stricter rules which modern society applies to the expression of Roman numerals are only a fairly recent change. back when Roman numerals were being etched on Roman buildings, it was not uncommon to see a number such as 400 expressed as CCCC, even though today we would express it as 100 before 500, i.e. CD.

There is no zero.Whenever a smaller number is to the left of a greater number, the smaller number gets subtracted from the greater number. Example: XC = 90 (100 - 10)A line over the top of a Roman numeral means it is multiplied by 1000.
