In todays modern notation of Roman numerals they are as follows:-
Units 1 to 9: I, II, III, IV, V, VI, VII, VIII and IX
Tens 10 to 90: X, XX, XXX, XL, L, LX, LXX, LXXX and XC
Hundred: C
To select a number simply write it out in descending order as for example 99 = XCIX
The way we write out Roman numerals today differs in many respects to how the ancient Romans actuallydid themselves as for example 99 = IC which in Latin is undecentum meaning one from a hundred.
