Old Persian numerals were treated somewhat like Roman numerals: they were based on juxtaposition or addition[PDF], and not place-value [PDF] like Arabic, Mayan, or Bablylonian numerals
Unlike Roman, the numerals were always placed in a single direction (largest-value-on-the-left); there was no subtractive notation like IV for 4. Also, Roman had symbols for 5 (V), 50 (L), 500 (D) instead of 2, 20.
So n Old Persian, "5" was 2 2 1 and "18" was 10 2 2 2 2. Decimal 453 would have been 100 100 100 100 20 20 10 2 1.
