Step-by-step explanation

1. 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:

$D (500) + C (100) + C (100) + X L (40) + I X (9)$

2. Sum values

Now add the values:
$500 + 100 + 100 + 40 + 9$ = $749$ .

So $D ℂ X L I X$ equals $749$ .
