Roman Numerals: 4

How to Convert 4 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 4, we combine these letters starting from the largest value and working down to the smallest.

Let's break 4 into parts and build the Roman numeral step by step:

4 fits into what's left of the number one time.
That means we add IV to our Roman numeral because one × four equals 4.

Final Answer

After combining all the parts, the Roman numeral for 4 is:

IV


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.

How to Convert the Roman Numeral IV into a Normal Number

To convert a Roman numeral to a normal number, we read it from left to right and add up the values of each symbol. However, if a smaller symbol appears before a larger one, we subtract the smaller value instead of adding it.

Let's break down IV step by step:

Step 1: We see IV, which means we subtract four (subtract 4).
This is a subtraction case because I is smaller than V.

Total calculation: IV (4) = 4

Final Answer

The normal number for the Roman numeral IV is:

4


Tip: Remember the key rule - if a smaller numeral appears before a larger one (like IV), subtract the smaller value. If a smaller one comes after a larger one (like VI), add the values together.
