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 many more applications. Here we will be discussing Roman numerals, rules, and examples.
Roman numerals can be seen in royal titles, such as Henry VIII, Henry IX, and so on. Have you noticed these titles and wondered what these symbols (VIII and IX) represented?
Those are Roman numerals. Ancient people used to count using fingers, sticks, bones, etc. As life became more complex, a standard form was required to count. Ancient 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 we use to count.
In Roman numerals, we use DCCCXXXIII to represent 833. Here, D is 500, CCC is 300, XXX is 30, and III is 3. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules for writing 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 a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8
To write larger numbers, some Roman numerals can be repeated up to three times. For example, CCC → 300.
If a small number precedes 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 VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 833 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 833 in Roman numerals using the expansion method. To write 833 in Roman numerals, follow these steps:
Step 1: Break the number down based on the place value: ones, tens, hundreds, etc.
For 833, we write it as 500 + 300 + 30 + 3.
Step 2: Convert each part into Roman numerals.
500 in Roman numerals — D
300 in Roman numerals — CCC
30 in Roman numerals — XXX
3 in Roman numerals — III
Step 3: Combine the Roman numerals together.
Therefore, 833 in Roman numerals is D(500) + CCC(300) + XXX(30) + III(3) = DCCCXXXIII
When writing a large number in Roman numerals, we group the numbers.
To write 833 in Roman numerals, we group 833 as 500 + 300 + 30 + 3.
500 in Roman numerals — D
300 in Roman numerals — CCC
30 in Roman numerals — XXX
3 in Roman numerals — III
So, 833 is written as DCCCXXXIII in Roman numerals.
Students often make mistakes when writing numbers in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
Calculate the square of DCCCXXXIII.
The square of DCCCXXXIII is DCXCIVCDLXXXIX.
First, convert DCCCXXXIII into Arabic numerals, which is 833.
The square of 833 is 833 × 833 = 694,089.
694,089 in Roman numerals is DCXCIVCDLXXXIX.
A library has a collection of DCCCXXXIII scrolls that need to be distributed equally among XIX sections. How many scrolls will each section receive?
Each section will receive XLIII scrolls.
To find the number of scrolls each section gets, divide the total number of scrolls by the number of sections.
DCCCXXXIII = 833
XIX = 19
833 ÷ 19 = 43
43 in Roman numerals is XLIII.
If you add DLXXIX and CCLIV, what will be the result in Roman numerals?
The sum of DLXXIX and CCLIV is DCCCXXXIII.
First, convert each Roman numeral to Arabic numerals:
DLXXIX = 579
CCLIV = 254
579 + 254 = 833
833 in Roman numerals is DCCCXXXIII.
What is the remainder when DCCCXXXIII is divided by XIII?
The remainder is I.
First, convert each Roman numeral to Arabic numerals:
DCCCXXXIII = 833
XIII = 13
833 ÷ 13 = 64 with a remainder of 1.
1 in Roman numerals is I.
Express the difference between CM and CLXVII using Roman numerals.
The difference between CM and CLXVII is DCCCXXXIII.
First, convert each Roman numeral to Arabic numerals:
CM = 900
CLXVII = 167
900 - 167 = 733
733 in Roman numerals is DCCCXXXIII.
