2 in Roman numerals

2 = II

Working: I = 1, I = 1

The number 2 is written as II in Roman numerals.

Roman numerals are built by adding symbol values together from largest to smallest: I = 1, I = 1. Where a smaller symbol appears before a larger one — as in IV for 4 or IX for 9 — it is subtracted rather than added, which keeps the notation short.

Structurally, II is 2 symbols long. It is entirely additive: every symbol adds to the running total, with no smaller symbol standing before a larger one. The longest run is 2 identical symbols.

II is two tally marks. The additive principle is at its plainest here: symbols are simply written side by side and summed. It is only when repetition would run to four identical symbols that the subtractive shortcuts appear.
