Roman numerals are a way of expressing numbers using symbols. The symbols I, V, X, L, C, D, and M are used in this system. Roman numerals are often seen in royal titles, book names, sequences, and more. Here we will be discussing Roman numerals, their rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you ever noticed these names and wondered what these symbols (I and II) represented? Those are Roman numerals.
People initially used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was needed for counting. Ancient Romans used the Roman numeral system for this purpose. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used to represent numbers.
In Roman numerals, we use CLXXXII to represent 182, where C is 100, L is 50, XXX is 30, and II is 2. 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 a smaller number is placed after a larger number. For example, CLXXXII → C + L + X + X + X + I + I → 100 + 50 + 10 + 10 + 10 + 1 + 1 = 182
Rule 2: Repetition Method
To write larger numbers, certain Roman numerals can be repeated up to three times. For example, XXX → 10 + 10 + 10 = 30.
Rule 3: Subtraction Method
If a smaller number precedes a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9
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, instead of writing LL for 100, we use C.
Let’s now learn how to write 182 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 182 in Roman numerals using the expansion method.
To write 182 in Roman numerals, follow these steps:
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc.
For 182, we write it as 100 + 80 + 2
Step 2: Convert each number into Roman numerals
100 in Roman numerals — C
80 in Roman numerals — LXXX
2 in Roman numerals — II
Step 3: Combine the Roman numerals together.
Therefore, 182 in Roman numerals is C (100) + LXXX (80) + II (2) = CLXXXII.
When writing a large number in Roman numerals, we group the number.
To write 182 in Roman numerals, we group 182 as 100 + 80 + 2
100 in Roman numerals — C
80 in Roman numerals — LXXX
2 in Roman numerals — II
So, 182 is written as CLXXXII in Roman numerals.
