You add the numbers together if numbers of the same size are placed next to each other or if a smaller number is placed to the right of a larger number. For example:
- II = 2
- III = 3
- VI = 6
- VIII = 8
- XX = 20
- XXI = 21
- CC = 200
You subtract the smaller number from the larger if a smaller number is placed to the left of a larger number. For example:
- IV = 4
- IX = 9
- XL = 40
- CD = 400
- CM = 900
Sometimes you will perform both operations:
- XIV = 14
- XIX = 19
