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, often use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman Numerals. Earlier people used to count using 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 DXXXII to represent 532, where D is 500, X is 10, and I is 1. 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.
The addition method is used when the smaller number is placed after the larger number. For example, DXXXII → D + X + X + I + I → 500 + 10 + 10 + 1 + 1 = 532
To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, X is repeated twice in DXXXII to represent 20.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4
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 VVV for 15; instead, we use XV.
Let’s now learn how to write 532 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 532 in Roman numerals using the expansion method.
To write 532 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 532, we write it as 500 + 30 + 2
Step 2: Convert the number into Roman Numerals
500 in Roman Numerals — D
30 in Roman Numerals — XXX
2 in Roman Numerals — II
Step 3: Combine the Roman Numerals together. Therefore, 532 in Roman Numerals is D (500) + XXX (30) + II (2) = DXXXII
When writing a large number in Roman Numerals, we group the number. To write 532 in Roman Numerals, we group 532 as 500 + 30 + 2
So, 532 is written as DXXXII in Roman Numerals.
