## Explanation

Capital and lower case Roman numerals are used in both literary and mathematical contexts. Roman numerals are brailled as regular letters using the rules for capitalization and grade 1 mode. A Roman numeral represented by a single letter standing alone will require grade 1 indicators with the exception of i, which does not have a grade 2 meaning.

The capital letter indicator, dot six is used before a single upper case Roman numeral. A sequence of Roman numerals written in upper case will require the capital word indicator, dot six, dot six.
