Roman numerals are a 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 more. Here we will discuss Roman Numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these symbols and wondered what they represent? Those are the Roman Numerals.
In ancient times, people counted using fingers, sticks, bones, etc. As life became more complex, a standard form was needed. The Romans developed the Roman Numeral system for this purpose. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used.
In Roman Numerals, we use DCXXXII to represent 632, where D is 500, C is 100, and XXXII is 32. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman Numerals. Let's discuss some basic rules that need to be remembered when writing a number in Roman numerals.
The addition method is used when a smaller number is placed after a larger number. For example, DCXXXII → D + C + XXX + II → 500 + 100 + 30 + 2 = 632.
Certain Roman Numerals can be repeated up to three times to form numbers. For instance, XXX → 30.
If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I = 5 - 1 = 4.
The symbols I, X, C, and M can be repeated up to three times, but symbols like V, L, and D cannot be repeated. For example, we use X for 10 instead of VV.
Let’s now learn how to write 632 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. Here is how we write 632 in Roman numerals using the expansion method. To write 632 in Roman Numerals, follow these steps:
Step 1: Break down the number based on the place value: hundreds, tens, and ones. For 632, we write it as 600 + 30 + 2.
Step 2: Convert each number into Roman Numerals:
600 in Roman Numerals- DC
30 in Roman Numerals - XXX
2 in Roman Numerals - II
Step 3: Combine the Roman Numerals: Therefore, 632 in Roman Numerals is D (500) + C (100) + XXX (30) + II (2) = DCXXXII.
When writing a large number in Roman Numerals, we group the number. To write 632 in Roman Numerals, group 632 as 600 + 30 + 2.
So, 632 is written as DCXXXII in Roman Numerals.
