Adding Mixed Numbers with Uncommon Denominators

To convert an Arabic number into a Roman numeral, the following Roman numeral conversion rule can be used.

To make the Roman numeral for the Arabic number 2, for example, the Roman numeral I is added to the same Roman numeral I making the Roman numeral II. Therefore, Roman numeral II is equal to the number 2.

1 = I

2 = I + I = II

3 = I + I + I = III

Roman numeral conversion rule

Example: 4 = 5 – 1 or V – I. V – I is written in Roman numeral form as IV.

As a Roman numeral conversion rule, when a letter representing a number of lesser value (I before V) appears to the left of a letter of greater value (V after I), the lesser value (I) is subtracted from the greater value (V).
