87 in words: Eighty-seven
To write eighty-seven you work from the largest value down: LXXX (80) + VII (7). Set each group in turn, left to right, and stop when there is nothing left over. That gives LXXXVII.
There is no subtraction to handle here, so every group in LXXXVII simply adds on. Numerals like this are the ones to practise on before you tackle the subtractive forms such as IV and IX.
What LXXXVII means, letter by letter
LXXXVII is 87, "eighty-seven". It is built from LXXX (80) and VII (7), read from the largest value down and added together. Every symbol here is added in sequence, with no subtraction involved.
To read LXXXVII back, scan it left to right, largest value first, adding as you go. The running total lands on 87:
| Read | Worth | Running total |
|---|---|---|
| LXXX | 80 | 80 |
| VII | 7 | 87 |
There is no subtraction anywhere in LXXXVII, so every letter simply adds to the total: no letter changes the meaning of the one next to it. Read aloud, LXXXVII is simply "eighty-seven".
Write LXXXVII step by step
The rule is always the same: take the largest Roman value that still fits, write its symbol, subtract it, and repeat until nothing is left over. Applied to 87 that gives 7 steps.
| Step | Take | Write | Numeral so far | Left to write |
|---|---|---|---|---|
| 1 | 50 | L | L | 37 |
| 2 | 10 | X | LX | 27 |
| 3 | 10 | X | LXX | 17 |
| 4 | 10 | X | LXXX | 7 |
| 5 | 5 | V | LXXXV | 2 |
| 6 | 1 | I | LXXXVI | 1 |
| 7 | 1 | I | LXXXVII | 0 |
Nothing is left over after step 7, so the finished numeral is LXXXVII. Written out in English words that is "Eighty-seven".
Forms to avoid when writing 87
These are the spellings people reach for instead, and why each one is wrong for 87.
- Not LXXXXVII. X already appears three times in LXXXVII, which is the maximum. A fourth X is never valid, so if you need more you move up to the next symbol instead.
- Not LXXXVVII. V never repeats. Two of them would simply be the next symbol up, so a doubled V is not a numeral at all.
Check LXXXVII reads back as 87
Writing a numeral and verifying it are two different jobs, and the second one is what saves you on anything permanent. Read LXXXVII back left to right, adding each group and treating any smaller-before-larger pair as a single subtraction. If you land on 87, the numeral is correct. The converter above does exactly this and refuses any non-standard spelling, so a value it accepts is a value you can use.
Where you will see LXXXVII

Numerals up to a hundred like LXXXVII are the ones you meet most: clock hours, chapter numbers, sequels and anniversaries all live in this range, so learning to read LXXXVII on sight pays off more often than any larger numeral would.
