Rules to Remember for CXXVI Roman Numerals

Understanding a few Roman numeral rules makes CXXVI easier to read and write.

1. Addition Rule

When a smaller Roman numeral comes after a larger numeral, the values are generally added.

For example:

XI = 10 + 1 = 11

Similarly:

CXXVI = 100 + 10 + 10 + 5 + 1 = 126

2. Repetition Rule

Some Roman numerals can be repeated up to three times in succession.

For example:

• III = 3

• XX = 20

• XXX = 30

• CCC = 300

The symbols V, L, and D are not normally repeated.

Therefore, 20 is written as XX, not VVVV.

3. Subtraction Rule

When a smaller Roman numeral appears before a larger one in an accepted subtraction combination, its value is subtracted.

For example:

• IV = 5 − 1 = 4

• IX = 10 − 1 = 9

• XL = 50 − 10 = 40

CXXVI does not use the subtraction rule because its symbols are arranged in descending value.
