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 earlier. 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 MML to represent 2050, where M is 1000, M is another 1000, and L is 50. 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, then it is the addition method. For example, MML → M + M + L → 1000 + 1000 + 50 = 2050
To write a large number, certain Roman Numerals can be repeated up to three times. For example, XXX → 30.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number; it is a subtraction method. 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 LL for 100; instead, we use C, and 80 is written as LXXX, not LXXXX.
Let’s now learn how to write 2050 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 2050 in Roman numerals using the expansion method.
To write 2050 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place value that is ones, tens, hundreds, etc.
For 2050, we write it as 2000 + 50
Step 2: Converting the number into Roman Numerals
2000 in Roman Numeral — MM
50 in Roman Numeral — L
Step 3: Combining them Roman Numerals together.
Therefore, 2050 in Roman Numeral is MM (2000) + L (50) = MML
When writing a large number into Roman Numeral, we group the number.
To write 2050 in Roman Numeral, we group 2050 as 2000 + 50
2000 in Roman Numeral — MM
50 in Roman Numeral — L
So, 2050 is written as MML 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 the ways to avoid them.
Calculate the total number of hours in L weeks and express it in Roman numerals.
The total number of hours in L weeks is MCMX.
In L weeks, there are 50 weeks. Each week has 7 days, and each day has 24 hours.
So, 50 weeks × 7 days/week × 24 hours/day = 8400 hours.
8400 in Roman Numerals is MCMX.
A company plans to distribute MMCCL computers equally among XLV branches. How many computers will each branch receive?
Each branch will receive L computers.
To find the number of computers per branch, we divide the total number of computers by the number of branches.
MMCCL = 2250
XLV = 45
2250 / 45 = 50
50 in Roman numerals is L.
Find the sum of MD and DL in Roman numerals.
The sum of MD and DL is MM.
Sum is the result of adding two numbers.
MD = 1500
DL = 550
1500 + 550 = 2050
2050 in Roman Numerals is MM.
The sum of MD and DL is MM.
What is the difference between MM and MCC in Roman numerals?
The difference between MM and MCC is DCCCL.
The difference of two numbers is the value we get when subtracting one number from the other.
MM = 2000
MCC = 1200
2000 - 1200 = 800
800 in Roman Numerals can be written as DCCCL.
Using the expansion method, write the Roman numeral for 1000 + 500 + 500 + 50.
The Roman numeral for 1000 + 500 + 500 + 50 is MM.
Step 1: Break down the numbers into their components.
1000 - M
500 - D
500 - D
50 - L
Add the numbers together: 1000 + 500 + 500 + 50 = 2050
Using the expansion method: 2050 = 1000 + 500 + 500 + 50 = MM.
