Standard roman numerals can only represent numbers up to 3999. An additional system or notation was eventually created for large numbers over 3999 and up to 3999999.

This additional system is called Vinculum notation.

The method is very simple. A bar is placed over a numeral character to signify that the character should be multiplied by 1000. For example, the number 5000 in vinculum notation would be:

VIn other words, 5 * 1000.

VXVAs with standard numerals, vinculum notation numerals run from left to right, from highest to lowest.
