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.
Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are Roman numerals. Earlier, people used to count using fingers, sticks, bones, etc. When life became complex, a standard form was required for counting.
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 DCCXXXII to represent 732. Here, D is 500, CC is 200, 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.
The addition method is used when the smaller number is placed after the larger number. For example, DCCXXXII → D + CC + XXX + II → 500 + 200 + 30 + 2 = 732.
To write a large number, certain Roman numerals can be repeated up to three times. For example, XXX → 30.
If a small number precedes a large number, it is subtracted from the large 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 VV for 10; instead, we use X.
Let’s now learn how to write 732 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 732 in Roman numerals using the expansion method. To write 732 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value: ones, tens, hundreds, etc. For 732, we write it as 700 + 30 + 2.
Step 2: Convert the number into Roman numerals.
Step 3: Combine the Roman numerals together. Therefore, 732 in Roman numerals is DCC (700) + XXX (30) + II (2) = DCCXXXII.
When writing a large number in Roman numerals, we group the number. To write 732 in Roman numerals, we group 732 as 700 + 30 + 2.
So, 732 is written as DCCXXXII in Roman numerals.
Students make mistakes when writing numbers in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
A historian discovered DCCXXXII ancient coins in a sunken ship. If each coin weighs I kilogram, what is the total weight of the coins?
The total weight of the coins is DCCXXXII kilograms.
Since each coin weighs 1 kilogram and there are DCCXXXII coins, the total weight is simply the number of coins. Therefore, the total weight is 732 kilograms. 732 in Roman numerals is written as DCCXXXII.
Calculate the difference between a year written as MMDCCLXIV and DCCXXXII.
The difference between MMDCCLXIV and DCCXXXII is MCMXXXII.
To find the difference, subtract the smaller number from the larger one.
MMDCCLXIV = 2764
DCCXXXII = 732
2764 - 732 = 2032
2032 in Roman numerals is MCMXXXII.
If a builder uses DCCXXXII bricks to construct a small wall, and each section of the wall uses CXV bricks, how many sections can he build?
The builder can build VI sections of the wall.
To determine the number of sections, divide the total number of bricks by the number of bricks per section.
DCCXXXII = 732
CXV = 115
732 / 115 = 6
6 in Roman numerals is VI.
A museum has DCCXXXII artifacts, and plans to display them in XL rooms equally. How many artifacts will each room have?
Each room will have XVIII artifacts.
To find how many artifacts each room will have, divide the total number of artifacts by the number of rooms. DCCXXXII = 732 XL = 40 732 / 40 = 18.3, rounding down gives 18 artifacts per room. 18 in Roman numerals is XVIII.
Convert the number of pages in a book, DCCXXXII, to Roman numerals using the breakdown method.
The Roman numeral for DCCXXXII is DCCXXXII.
Breakdown the number 732: 700 = DCC 30 = XXX 2 = II
Combine them: DCC + XXX + II = DCCXXXII
