800 in words: Eight hundred
Writing 800 is one of the easier jobs in the system: it is a round value, so it lands on whole groups with no remainder. Set DCCC (800) in that order and DCCC is finished.
Round hundreds and thousands are worth being able to write without thinking, because almost every longer numeral starts with one of them and then adds a tail.
What DCCC means, letter by letter
DCCC is 800, "eight hundred". It is built from a single group, DCCC (800). Every symbol here is added in sequence, with no subtraction involved.
To read DCCC back, scan it left to right, largest value first, adding as you go. The running total lands on 800:
| Read | Worth | Running total |
|---|---|---|
| DCCC | 800 | 800 |
There is no subtraction anywhere in DCCC, so every letter simply adds to the total: no letter changes the meaning of the one next to it. Read aloud, DCCC is simply "eight hundred".
Write DCCC 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 800 that gives 4 steps.
| Step | Take | Write | Numeral so far | Left to write |
|---|---|---|---|---|
| 1 | 500 | D | D | 300 |
| 2 | 100 | C | DC | 200 |
| 3 | 100 | C | DCC | 100 |
| 4 | 100 | C | DCCC | 0 |
Nothing is left over after step 4, so the finished numeral is DCCC. Written out in English words that is "Eight hundred".
Forms to avoid when writing 800
These are the spellings people reach for instead, and why each one is wrong for 800.
- Not DCCCC. C already appears three times in DCCC, which is the maximum. A fourth C is never valid, so if you need more you move up to the next symbol instead.
- Not DDCCC. D never repeats. Two of them would simply be the next symbol up, so a doubled D is not a numeral at all.
Check DCCC reads back as 800
Writing a numeral and verifying it are two different jobs, and the second one is what saves you on anything permanent. Read DCCC back left to right, adding each group and treating any smaller-before-larger pair as a single subtraction. If you land on 800, 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 DCCC
