Roman numeral to integer

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:

M(1000)+D(500)+C(100)+C(100)+XC(90)+IX(9)

2. Sum values

Now add the values:
1000+500+100+100+90+9 = 1,799.

So MDXCIX equals 1,799.
