Evaluate Roman Numerals
Roman numerals represent values with ordered symbols and standard subtractive pairs. The converter applies those rules to valid integers.
Formula: Use place-value symbols such as I, V, X, L, C, D and M with subtractive forms IV, IX, XL, XC, CD and CM
The calculator follows the mathematical relationship shown in the formula. Keeping symbols and values in their intended positions avoids many avoidable errors.
Use one simple test case to confirm the expected scale of the answer before processing a larger set of values.
