4 in Roman numerals is written as IV. Roman numerals use letters like I, V, and X to show numbers. These letters come from the number system used by people in ancient Rome. Each letter carries a value, and by putting them in a different order, we can make different numbers.
So, when we say four in Roman numbers, we use two Roman letters, which are I (which means 1) and V (which means 5), to get IV. Nowadays, we can see 4 Roman numerals along with others on old clocks or book chapters. Keep reading to learn more about the basic rules for writing four in Roman numbers.

4 in Roman Numerals
4 number in Roman is written as IV. This is because Roman numerals follow both addition and subtraction rules. Instead of writing four as four I’s (IIII), the Romans used a smarter way. In Roman numerals, I stands for 1 and V stands for 5.
So, to write 4 in Roman letters, we place I before V. This means we subtract 1 from 5. So, 5 minus 1 becomes 4. That’s why 4 in Roman numerals is written as IV. This method keeps the numbers short and easy to read. That’s how the 4 number in Roman is written using just two letters.
Basic Rules to Write Four in Roman Numbers
Roman numerals follow simple rules that help us understand how to correctly write numbers like 4 in Roman numerals. Once you know these rules, reading and writing numbers like 4th in Roman numerals becomes very easy. Here are the rules you need to know:
-
When a smaller letter comes before a bigger one, we subtract. For example, IV means 5 - 1, which is 4. That’s how we write four in Roman numbers.
-
When a bigger letter comes before a smaller one, we add. For example, VI means 5 + 1 = 6.
-
If a letter is repeated, we add the values. For example, III means 1 + 1 + 1 = 3.
-
The same letter cannot be repeated more than three times in a row. That’s why we don’t write 4 as IIII. Instead, we write it as IV.
These rules help us write numbers like 4 in Roman letters in the right way, without making mistakes.

Why Do We Write 4 as IV and Not IIII in Roman Numerals?
Have you ever wondered why 4 in Roman numerals is written as IV and not IIII? Let’s understand the reason behind it. In Roman numerals, there's a rule that says we should not repeat the same letter more than three times in a row. That means we can write 1 as I, 2 as II, and 3 as III. But writing 4 as IIII would break the rule.
So, instead of adding four I’s, the Romans used a smart trick. They wrote I before V, which means we subtract 1 from 5. That gives us IV, which is the correct way to write 4 in Roman letters. This rule not only keeps the writing short but also neat. That’s why we always write 4 in Roman letters as IV and not IIII.

Common Mistakes to Avoid While Writing 4 in Roman Letters
While writing 4 in Roman letters, many children make small mistakes. Here are a few common ones you should try to avoid:
Writing “IIII” instead of “IV”
A common mistake is repeating the letter I four times. But as per Roman numeral rules, the same letter should not be used more than three times in a row. So, four in Roman number must be written as IV, not IIII.
Mixing up IV and VI
Some students get confused between IV and VI. Remember, IV means 4 and VI means 6. The order of the letters is important. In IV, I comes before V, so we subtract (5 - 1 = 4). In VI, I comes after V, so we add (5 + 1 = 6).
Adding instead of subtracting in IV
Sometimes, kids think that IV means 1 + 5, which gives 6. But that is not correct. Since I come before V, we subtract. So 4 in Roman letters is written as IV, meaning 5 - 1. Learning these small rules will help you write the 4 number in Roman correctly every time.
