Many persons are familiar with the Roman numerals for relatively small
numbers. The symbols I (capital i), V, X, L,
C, D, and M represent the decimal values
1, 5, 10, 50, 100, 500 and 1000 respectively. To represent other values,
these symbols, and multiples where necessary, are concatenated, with the
smaller-valued symbols written further to the right. For example,
the number 3 is represented as III, and the value 73 is represented
as LXXIII. The exceptions to this rule occur for numbers having units
values of 4 or 9, and for tens values of 40 or 90. For these cases, the
Roman numeral representations are IV (4), IX (9), XL (40), and XC (90).
So the Roman numeral representations for 24, 39, 44, 49, and 94 are
XXIV, XXXIX, XLIV, XLIX, and XCIV,
respectively.
