For example, IV means 4, VI means 6.<br /> <br /> You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.<br /> <br /> You must separate ones, tens, hundreds, and thousands as separate items. That means that 99 is XCIX, 90 + 9, but never should be written as IC. Similarly, 999 cannot be IM and 1999 cannot be MIM. <br /> <br /> Sometimes you will see a numeral with a line over it. That means to multiply it by 1000. A numeral V with a line over it means 5000. This usage is no longer current, because the largest numbers usually expressed in the Roman system are dates.<br /> <br /> <br /> <table style="width: 90%;"><tbody> <tr> <th>Symbols</th> <th></th> </tr> <tr> <td>I</td> <td>The numeral one. II is two, III is three. You seldom see IIII as 4, since IV can also mean 4, plus its shorter to write.</td> </tr> <tr> <td>V</td> <td>The numeral 5.
