The Romans would have written it as IIII We would write it as IV
iv is 4 in Hindu-Arabic. The Romans themselves would have used iiii, as they didn't use iv or ix (9) very often.
IIII (or IV) is a Roman numeral which represents the number 4.
Although the normal way to write the number four in Roman numerals is IV, that isn't much easier to write than IIII (if you count the pen strokes, it's 3 strokes vs. four strokes) and this system was intended by the Romans to be convenient to use, so they allowed that variation.
The Romans themselves would have used I, II, III, IIII, V. However more recent conventions replaced IIII with IV.
