In the Baltics and Russia, the days of the week are often written as Roman numerals, with I being Monday. Instead of writing the same letter four times, a rule for subtraction is used. The letter is written once, then the next largest Roman numeral is written. When a lower number (such as I) appears before a higher one (such as V), the lower number is subtracted from the higher one. For example, 4 is not written as IIII, but instead as IV, because IV is V (5) minus I (1). The same is done for 9 - it is not written as VIIII, but instead as IX, because IX is X (10) minus I (1).
