I = 1 V = 5 X = 10
The ancient Romans used several letters to write
numbers. The letters they used to write numbers
up to 10 are shown in the box to the right.
If the smaller Roman numeral is written before the larger Roman numeral, subtract the
smaller value from the larger. For example:
IV = 5
1 = 4
If the smaller Roman numeral is written after the larger Roman numeral, add the values.
For example:
VI = 5
1 = 6
