How to Convert 30 into Roman Numerals

Roman numerals are made up of seven letters: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). To write a number like 30, we combine these letters starting from the largest value and working down to the smallest.

Let’s break 30 into parts and build the Roman numeral step by step:

10 fits into what’s left of the number three times.
That means we add XXX to our Roman numeral because three × ten equals 30.

Final Answer

After combining all the parts, the Roman numeral for 30 is:

XXX

Tip: If a smaller numeral appears before a larger one (like IV), it means you subtract. If a smaller one comes after a larger one (like VI), it means you add. You’ll see both styles when needed.
