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 so on. Here we will be discussing Roman Numerals, rules, and examples.
The 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 the Roman Numerals.
Earlier people used to count using fingers, sticks, bones, etc. 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 DLXXII to represent 572, where D is 500, L is 50, 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, then it is the addition method. For example, DLXXII → D + L + X + X + I + I → 500 + 50 + 10 + 10 + 1 + 1 = 572.
To write a large number, there are certain Roman Numerals that can be repeated three times. For example, III → 3.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number; it is a subtraction method. For example, IX → X - I → 10 - 1 = 9.
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 VV for 10; instead, we use X. Similarly, 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 572 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 572 in Roman numerals using the expansion method. To write 572 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place values are ones, tens, hundreds, etc. For 572, we write it as 500 + 70 + 2.
Step 2: Converting the number into Roman Numerals: 500 in Roman Numeral — D 70 in Roman Numeral — LXX 2 in Roman Numeral — II
Step 3: Combining them Roman Numerals together. Therefore, 572 in Roman Numeral is D (500) + LXX (70) + II (2) = DLXXII.
When writing a large number into Roman Numerals, we group the number. To write 572 in Roman Numerals, we group 572 as 500 + 70 + 2.
So, 572 is written as DLXXII in Roman Numerals.
A historian discovered DXXII artifacts and wants to distribute them equally among XIII museums. How many artifacts will each museum receive?
A collector has a collection of DXXII coins, and he sells CCLXII of them. How many coins does he have left?
Convert the sum of CCC and CCLXXII into Roman numerals.
A library has a total of DXXII books, and it plans to add another L to its collection. What will be the new total number of books in Roman numerals?
Write the Roman Numeral for 572 using the expansion method.
