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 and Henry II, use Roman Numerals. Have you noticed these 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. As life became more 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 MLI to represent 1051. Here, M is 1000, L is 50, 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 the smaller number is placed after the larger number. For example, MLI → M + L + I → 1000 + 50 + 1 = 1051
To write a large number, certain Roman Numerals can be repeated up to three times. For example, III → 3.
If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9
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 for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 1051 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 1051 in Roman numerals using the expansion method. To write 1051 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 1051, we write it as 1000 + 50 + 1
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 1051 in Roman Numerals is M (1000) + L (50) + I (1) = MLI
When writing a large number in Roman Numerals, we group the number. To write 1051 in Roman Numerals, we group 1051 as 1000 + 50 + 1
So, 1051 is written as MLI 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 the ways to avoid them.
Calculate the product of D and XI.
The product of D and XI is VL.
In numbers, D is 500 and XI is 11. The product of D and XI is 500 × 11 = 5500. 5500 in Roman Numerals can be written as VL.
A library has a collection of MCDII books and wants to distribute them equally among CXX students. How many books will each student receive?
Each student will receive XI books.
To find the number of books each student receives, divide the total number of books by the number of students. MCDII = 1402 CXX = 120 Therefore, 1402 / 120 = 11.68 (rounded to 11) 11 in Roman Numerals is XI.
Find the sum of CMXL and CXI.
The sum of CMXL and CXI is MLI.
Sum is the result of adding two numbers.
CMXL = 940
CXI = 111
940 + 111 = 1051
1051 in Roman Numerals is MLI.
What is the difference between ML and CXLIX?
The difference between ML and CXLIX is DCCI.
The difference of two numbers is the value we get when subtracting one number from another.
ML = 1050
CXLIX = 149
1050 - 149 = 901
901 in Roman Numerals can be written as DCCI.
Express the sum of DLIII and DXLVIII in Roman Numerals.
The sum of DLIII and DXLVIII is MXI.
Step 1: Convert DLIII and DXLVIII into numbers.
DLIII = 553
DXLVIII = 498
Add the numbers together: 553 + 498 = 1051
1051 in Roman Numerals is MXI.
