Know which letters stand for which numbers. I is 1, V is 5. X is 10, L is 50. C is 100, D is 500. M is 1000.
Locate the largest symbol within the number. This should be either the first or the second symbol.
If the largest symbol appears first, count how many times it appears in an uninterrupted row. This should be between one and three times. Multiply its value by the number of appearances and add this amount to the total.
If the largest symbol appears second, subtract the value of the symbol before it from its value. Add this amount to the total.
Repeat steps 2-4 with the numbers you have not yet accounted for.
Add up the values of each set of numbers to find the total value of the entire numeral.
