How MCMLXXXVII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1987 separately and joining the pieces gives MCMLXXXVII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 8 | 80 | LXXX |
| Ones | 7 | 7 | VII |
Reading it back, left to right:
- M = 1,000 → running total 1,000
- CM = 900 (M minus C) → running total 1,900
- L = 50 → running total 1,950
- X = 10 → running total 1,960
- X = 10 → running total 1,970
- X = 10 → running total 1,980
- V = 5 → running total 1,985
- I = 1 → running total 1,986
- I = 1 → running total 1,987
Why MCMLXXXVII has 10 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMLXXXVII after MCM — LXXXVII — spells out 87. Of the 201 years from 1900 to 2100, 1 have a longer numeral and 195 a shorter one.
The rules MCMLXXXVII follows
- Largest to smallest. MCMLXXXVII uses the symbols M, C, L, X, V and I (10 characters in all), and the values never increase from left to right except inside a subtractive pair.
- Subtraction. CM (900) is a subtractive pair: a smaller symbol in front of a larger one is taken away from it. Only six pairs are allowed — IV, IX, XL, XC, CD and CM — and MCMLXXXVII uses one of them.
- Repetition. XXX repeats X three times and II repeats I two times. I, X, C and M may repeat up to three times in a row; V, L and D never repeat.
Common mistakes when writing 1987
- MDCCCCLXXXVII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMLXXXVII.
The year 1987 in Roman numerals: where it appears
- Film and TV credits. Copyright lines at the end of films and TV programs of the period commonly gave the year in numerals — a 1987 production might end with “Copyright MCMLXXXVII.”
- Championship numbering. The pro football championship played in early 1987 was game XXI (21), since the series began with game I in January 1967.
- On a calendar. 1987 was not a leap year (365 days), and January 1 fell on a Thursday. A full date such as July 4, 1987 is often written VII · IV · MCMLXXXVII.
