126 in roman numerals

Royal titles such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman numerals. In earlier times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was needed. The ancient Romans used the Roman numeral system. The symbols we use for counting are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

In Roman numerals, we use CXXVI to represent 126, where C is 100, XX is 20 (10+10), and VI is 6 (5+1). Let’s learn more about Roman numerals and how we write them.

There are certain basic rules for writing numbers in Roman numerals. In this section, let’s discuss some basic rules that need to be remembered.

Rule 1: Addition Method

The addition method is used when a smaller number is placed after a larger number. For example, VI → V + I → 5 + 1 = 6

Rule 2: Repetition Method

To write larger numbers, certain Roman numerals can be repeated up to three times. For example, XX → 20 (10+10).

Rule 3: Subtraction Method

If a smaller number is placed before a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X.

Let’s now learn how to write 126 in Roman numerals. Follow these methods:

• By Expansion Method

• By Grouping Method

In the expansion method, based on the place value, the number is broken down. Here is how to write 126 in Roman numerals using this method:

Step 1: Break the number based on place value: hundreds, tens, and ones. 

For 126, we write it as 100 + 20 + 6.

Step 2: Convert each part into Roman numerals:

100 in Roman numerals — C
20 in Roman numerals — XX
6 in Roman numerals — VI

Step 3: Combine them together:

Therefore, 126 in Roman numerals is C (100) + XX (20) + VI (6) = CXXVI

When writing a large number in Roman numerals, we group the numbers together. 

For 126, we group it as 100 + 20 + 6:
100 in Roman numerals — C
20 in Roman numerals — XX
6 in Roman numerals — VI
So, 126 is written as CXXVI in Roman numerals.

Roman numerals follow a pattern that makes them look similar. Here are some numbers related to 126:

• Addition Rule: The addition method is used when a larger numeral is followed by a smaller one. For example, CXXVI = C + XX + VI = 100 + 20 + 6 = 126.

• Grouping Method: Here, numbers are grouped based on place value and converted to Roman numerals. For example, 126 = 100 + 20 + 6 = CXXVI.

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeral system can be repeated up to three times. For example, XX = 20 (X is repeated twice).

• Subtraction Method: This method is used when a smaller numeral precedes a larger one. For example, XC = 90 (C  X = 100  10).

• Limitation Rule: Certain symbols like V, L, and D cannot be repeated. For example, 10 is written as X, not VV.
