What is ixxv in roman numerals?

Answer 1

IXXV is not a correctly constructed Roman Numeral. Theoretically as IX represents 9 and XV represents 15 you might suppose that 9 + 15 would mean that it represented 24 but as numerals should always start with the symbol of greatest value and IX is lower in value than 15 IXXV is obviously incorrect. The universally accepted correct method of writing 24 in Roman numerals is XXIV (or less commonly XXIIII).
