There are no four I-s coming together in Roman number system. The I on left of X indicates that I has a negative value, ie, 10 - 1=9.

Only if tally marks it would be four lines and a cross line over it. Which looks very different than the v. Roman numerals were written on narrow stone slabs. So they were short to be the three characters only. Unless year like 1903 MCMIII

Source(s): Edit add https://www.hautehorlogerie.org/en/encyclopaedia/g... Roman numeral IIII on dials. VIIII = 9, (...) XVIIII = 19, (...) XXIIII = 24, to limit examples to the numerals that would later be marked on a dial to indicate the twenty-four hours in a day. During the Imperial period, the subtractive principle

IX is correct

In Roman Numerals, you never use more than 3 1's.

the only correct way to signify 4.........is IV = 5-1

If you wanted to write 1994......You wouldn't write MDCCCC for 1900. you write MCM

1000 + (1000-100) = 1900

to write the 94........again, you don't write LXXXX for 90. again, it would be XC......100-10

to write the 4......you don't write llll you use lV

so 1994 would be MCMXCIV......NOT MDCCCCVXXXXIIII

IX. There is never more than three ones added to a five.

IX is the correct annotation.

It could be either, in Roman thinking, but in practice IX is used. The use of those four instances of "I" is in fact never seen in modern times. A thorough scan of ancient documents would probably turn up a few instances of "--IIII" at the end of a Roman numeral.

IX is 10 minus 1 aka 9

Most people would probably recognize the 5 plus 4 VIIII standing alone as an intended 9 too .

But writing it that way would get would confusing in combination with other random numbers.

IX. The rule is the number X9 is written this way. So "18" would be "XVIII" but "19" would be "IXX".

It is IX but I have seen it the other way too.
