IV Roman Numerals

IV Roman numerals represent the number 4. The numeral IV is a classic example of subtraction notation, where a smaller numeral is placed before a larger one. To represent IV  Roman numerals in numbers, we have to subtract the Roman numerals I (1) from V (5) as: IV = V - I. Since V comes after I, we simply subtract the value of numbers to get: IV = 5 - 1 = 4. Therefore, the Roman numeral IV is correctly expressed in numbers as 4.

Each Roman numeral like IV represents a unique number, and we can form more such numbers if we know the Roman numeral rules. In this article, we will learn in detail about how to write VI Roman numerals in numbers, along with rules and solved problems based on VI Roman numerals. By going through this page you can easily understand and interpret Roman numerals.

Basic Rules for Writing Roman Numerals

To write IV and other Roman numerals correctly, remember these simple rules:

1. Subtraction notation:

When a smaller numeral is placed before a larger number, subtract the smaller number.

Example: IV = 5 - 1 = 4

2. Additive notation:

When a smaller numeral is followed by a larger one, add the values.

Example: VI = 5 + 1 = 6

3. Repetition rule:

The numerals I, X, C, and M can be repeated up to three times in succession.

4. Non-repeating symbols:

The symbols V, L, and D are never repeated.

5. Descending order rule:

Write the numerals from largest to smallest without using subtraction notation.
