The Roman numeral for 9 is the symbol ‘IX’. It is a combination of the numerals ‘I’ (1) and ‘X’ (10), representing the subtraction of ‘I’ from ‘X’. For instance, the time ‘9:00’ is written as ‘IX:00’ using Roman numerals.
Roman numerals have historical significance and are still used in certain contexts. Their simplicity and subtractive notation make them useful for representing small numbers, such as in clocks and chapter numbering. The use of ‘IX’ to represent ‘9’ is a key development that demonstrates the flexibility and effectiveness of Roman numerals.
