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 often found in royal titles, book names, sequences, and more. Here we will be discussing Roman Numerals, their rules, and examples.
The royal titles, such as Henry I, Henry II, and so on. 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. As life became complex, a standard form was required for counting. Ancient Romans used 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 CMLXI to represent 961, here CM is 900, LX is 60, 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 a smaller number is placed after a larger number. For example, LXI → L + X + I → 50 + 10 + 1 = 61
To write a large number, certain Roman Numerals can be repeated up to three times. III → 3.
If a small number is placed before a larger number in Roman Numerals, it is subtracted from the larger number. For example, CM → M - C → 1000 - 100 = 900
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 961 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 961 in Roman numerals using the expansion method.
To write 961 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value: ones, tens, hundreds, etc. For 961, we write it as 900 + 60 + 1
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 961 in Roman Numeral is CM (900) + LX (60) + I (1) = CMLXI
When writing a large number into Roman Numerals, we group the number. To write 961 in Roman Numerals, we group 961 as 900 + 60 + 1
So, 961 is written as CMLXI in Roman Numerals.
Students often make mistakes when writing numbers in Roman Numerals. To master Roman Numerals, we can learn from a few common mistakes and the ways to avoid them.
A historian finds CMXLI ancient coins buried at a site, each marked with the numeral IX. How many coins are there in total?
There are a total of CMXLI coins.
The numeral IX represents the number 9.
If each of the CMXLI coins is marked with IX, it means there is one numeral IX on each coin.
CMXLI itself represents the number 941, indicating there are 941 coins in total.
A library receives a donation of CMXLI books and plans to place them evenly on XLVII shelves. How many books will each shelf hold?
Each shelf will hold XX books.
To determine how many books each shelf will hold, divide the total number of books by the number of shelves.
CMXLI = 941
XLVII = 47
941 / 47 = 20
20 in Roman numerals is XX.
Therefore, each shelf will hold XX books.
A collector has a series of CMXLI stamps and wants to add XL more to complete his collection. What will be the new total in Roman numerals?
The new total will be CMXCI.
To find the new total, add the number of additional stamps to the current collection.
CMXLI = 941
XL = 40
941 + 40 = 981
981 in Roman numerals is CMXCI.
A game requires players to subtract IX from CMXLI to find the secret code. What is the secret code in Roman numerals?
The secret code is CMXXXII.
Subtract IX from CMXLI to find the secret code.
CMXLI = 941
IX = 9
941 - 9 = 932
932 in Roman numerals is CMXXXII.
Convert the expression 961 – 20 into Roman numerals using the subtraction method.
The result of 961 – 20 is CMXLI.
To perform the subtraction, first convert the numbers to Roman numerals.
961 = CMLXI
20 = XX
Subtract 20 from 961: 961 - 20 = 941
941 in Roman numerals is CMXLI.
