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.
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 XLI to represent 41; here, XL is 40, 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.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, VI → V + I → 5 + 1 = 6.
Rule 2: Repetition Method
To write a large number, there are certain Roman numerals that can be repeated up to three times. III → 3.
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the large number. For example, XL → L - X → 50 - 10 = 40.
Rule 4: Limitation Rule
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 LL for 100; instead, we use C, and 80, we write as LXXX, not LLLL.
Let’s now learn how to write 41 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 41 in Roman numerals using the expansion method.
To write 41 in Roman numerals, follow the steps:
Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc.
For 41, we write it as 40 + 1.
Step 2: Converting the numbers into Roman numerals:
40 in Roman numerals — XL
1 in Roman numerals — I
Step 3: Combine them into Roman numerals together.
Therefore, 41 in Roman numerals is XL (40) + I (1) = XLI.
When writing a large number into Roman numerals, we group the number.
To write 41 in Roman numerals, we group 41 as 40 + 1:
40 in Roman numerals — XL
1 in Roman numerals — I
So, 41 is written as XLI in Roman numerals.
A historian finds a manuscript stating that XLII soldiers were stationed at a fort and XXIX reinforcements arrived later. How many soldiers are now at the fort?
An ancient scroll mentions that a treasure chest contains CLX jewels and is divided equally among IV heirs. How many jewels does each heir receive?
A merchant sells XCIII apples but later discovers that he had mistakenly counted X less. What is the corrected count of apples sold?
Determine the result of subtracting XIV from LV.
Write the Roman Numeral for 41 + 59 using the expansion method.
