Roman numerals are the way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became complex, a standard form was required to count. Ancient Romans used the Roman numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman numerals, we use CXXXVI to represent 136, where C is 100, X is 10, and VI is 6. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, CXXXVI → C + XXX + VI → 100 + 30 + 6 = 136.
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, XXX → 30.
Rule 3: Subtraction Method
If a small number is followed by 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
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write LL for 100; instead, we use C.
Let’s now learn how to write 136 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 136 in Roman numerals using the expansion method.
To write 136 in Roman numerals, follow these steps:
Step 1: Break the number based on the place value. Place value includes ones, tens, hundreds, etc.
For 136, we write it as 100 + 30 + 6.
Step 2: Convert each number into Roman numerals:
100 in Roman numerals is C.
30 in Roman numerals is XXX.
6 in Roman numerals is VI.
Step 3: Combine the Roman numerals together
Therefore, 136 in Roman numerals is C (100) + XXX (30) + VI (6) = CXXXVI.
When writing a large number as a Roman numeral, we group the number. To write 136 in Roman numerals, we group 136 as 100 + 30 + 6.
100 in Roman numerals is C.
30 in Roman numerals is XXX.
6 in Roman numerals is VI.
So, 136 is written as CXXXVI in Roman numerals.
