4 in Roman Numerals

Writing 4 in Roman numerals involves representing 4 using Latin symbols V(5) and I(1). Since 4 is 1 less than 5, these symbols V and I are combined as per the subtraction rule. To convert 4 in Roman numerals, we first have to split it into parts as: 4 =  5(V) – 1(I) and then replace each number with its respective symbol: 4 = 5 – 1 = V – I = IV. 

Understanding how to read and write numbers, such as 4 in Roman numerals, helps students to connect mathematics to history. It also improves their logical thinking to combine smaller values to form larger numbers. Let’s learn how to write 4 in Roman Numerals, along with examples and solved problems.

How to Write 4 in Roman Numerals?

To write 4 in Roman numerals, we have to first break it down as 5 – 1 and replace the digits with symbols as V – I to get IV.

Let's understand this process step-by-step:

Step 1: Expand and write 4 in parts as: 4 =  5 – 1.

Step 2: Now, replace each digit with the respective Roman numeral: V – 1.

Step 3: Combine and write symbols as per subtractive rule of Roman numerals: 4 = IV.

So, 4 in Roman numeral is equivalent to IV

Basic Rules to Write Roman Numerals

Roman numerals follow some specific rules that help us write, convert and interpret them correctly:

• Addition Rule: When smaller numerals follow larger ones, their values are added.
  Example: VI = 5 + 1 = 6

• Subtraction Rule: When a smaller numeral comes before a larger one, it is subtracted.
  Example: IX = 10 − 1 = 9

• Repetition Rule: Symbols I, X, C, and M can be repeated up to three times.
  Example: XXX = 30

• Non-Repetition Rule: Symbols V, L, and D cannot be repeated.
   

Solved Examples on 4 in Roman Numerals 

Example 1: Find the difference between X(10) and VI(6) in Roman numerals?

Solution: We know that X = 10 and VI = 6

By subtracting the numeric values of X and VI we get: 10 – 6 = 4.

As, 4 is written as IV in Roman numerals

Therefore, X – VI = IV

 

Example 2: What is the value of IV(4) + VI(6) in Roman numerals?

Solution: First, write the value of IV and VI in numbers:

IV = 4 and VI = 6

Now add them to get their sum: 4 + 6 = 10

10 in Roman numerals is X.

Therefore, IV + VI = X

 

Example 3: Solve XXIV(24) – VI(6) and express the result in Roman numerals?

Solution: XXIV = 24 and VI = 6

By subtracting the values, we get: 24 ÷ 6 = 4

Therefore, XXIV ÷ VI = IV
