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., to count. 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 DCCCXXXVII to represent 837. Here, D is 500, CCC is 300, XXX is 30, and VII is 7. 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, VII → V + II → 5 + 2 = 7
To write a large number, certain Roman numerals can be repeated three times. CCC → 300.
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40
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 DD for 1000; instead, we use M, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 837 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 837 in Roman numerals using the expansion method. To write 837 in Roman numerals, follow the steps:
Step 1: Break the number based on place value. The place values are units, tens, hundreds, etc.
For 837, we write it as 800 + 30 + 7
Step 2: Converting the numbers into Roman numerals
800 in Roman numerals — DCCC
30 in Roman numerals — XXX
7 in Roman numerals — VII
Step 3: Combining them together.
Therefore, 837 in Roman numerals is DCCC (800) + XXX (30) + VII (7) = DCCCXXXVII
When writing a large number into Roman numerals, we group the number.
To write 837 in Roman numerals, we group 837 as 800 + 30 + 7
800 in Roman numerals — DCCC
30 in Roman numerals — XXX
7 in Roman numerals — VII
So, 837 is written as DCCCXXXVII in Roman numerals.
Students make mistakes when writing a number in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
A historian discovers DCCCXXXVII ancient coins and wants to equally distribute them into VII collections. How many coins will each collection receive?
Each collection will receive CXIX coins.
To find the number of coins each collection receives, divide the total number of coins by the number of collections.
DCCCXXXVII = 837
VII = 7
Therefore, 837 / 7 = 119.
119 in Roman numerals is CXIX.
A mural depicts DCCCXXXVII stars and needs to be divided into XIII panels. How many stars will each panel show?
Each panel will show LXIV stars.
To determine how many stars each panel shows, divide the total stars by the number of panels.
DCCCXXXVII = 837
XIII = 13
Therefore, 837 / 13 = 64.
64 in Roman numerals is LXIV.
An artist painted DCCCXXXVII unique patterns, and a collector wants to buy patterns in groups of XXIII. How many groups can the collector buy?
The collector can buy XXXVI groups of patterns.
To find out how many groups the collector can buy, divide the total number of patterns by the group size.
DCCCXXXVII = 837
XXIII = 23
Therefore, 837 / 23 = 36.
36 in Roman numerals is XXXVI.
Calculate the sum of DCCC and XXXVII in Roman numerals.
The sum of DCCC and XXXVII is DCCCXXXVII.
Sum is the result of adding two numbers.
DCCC = 800
XXXVII = 37
800 + 37 = 837
837 in Roman numerals is DCCCXXXVII.
What is the difference between DCCCXL and DCCCXXXVII?
The difference between DCCCXL and DCCCXXXVII is III.
The difference of two numbers is the value we get when subtracting one number from the other.
DCCCXL = 840
DCCCXXXVII = 837
840 - 837 = 3
3 in Roman numerals is III.
