Step-by-step explanation

1. Clean up the input

Your input was cleaned into standard Roman numeral form: $r o m a n (D ℂ C X L)$ → $D ℂ C X L$ .

2. Expand symbols

Read left to right.
If a smaller symbol comes before a larger one, treat them as one subtractive pair (for example, IX = 9).
Otherwise, each symbol stands alone.

For this input we get:

$D (500) + C (100) + C (100) + C (100) + X L (40)$

3. Sum values

Now add the values:
$500 + 100 + 100 + 100 + 40$ = $840$ .

So $D ℂ C X L$ equals $840$ .
