Roman numerals are a method of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols used. Roman Numerals are utilized in royal titles, book names, sequences, and more. Here we will be discussing Roman Numerals, rules, and examples.
Roman numerals are often seen in various contexts such as royal titles, like Henry I or Henry II. These symbols (I and II) are part of the Roman Numeral system. In ancient times, people counted using fingers, sticks, and bones. As civilization progressed, a standard form of counting became necessary. The Romans developed the Roman Numeral system using symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman Numerals, we use DCCXCVIII to represent 798. Here, D is 500, CC is 200, XC is 90, and VIII is 8.
Let’s learn more about Roman numerals and how we write them.
There are certain basic rules for writing numbers in Roman Numerals. In this section, let’s discuss the basic rules to remember when writing numbers in Roman numerals.
The addition method is used when a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8.
Certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
If a smaller number precedes a larger number in Roman Numerals, it is subtracted. For example, XC → C - X → 100 - 10 = 90.
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. For 8, we use VIII, not IIIIIIII.
Let’s now learn how to write 798 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 798 in Roman numerals using the expansion method.
To write 798 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc. For 798, we write it as 700 + 90 + 8.
Step 2: Converting each number into Roman Numerals:
Step 3: Combine the Roman Numerals together. Therefore, 798 in Roman Numerals is DCC (700) + XC (90) + VIII (8) = DCCXCVIII.
When writing a large number in Roman Numerals, we group the number. To write 798 in Roman Numerals, we group 798 as 700 + 90 + 8.
So, 798 is written as DCCXCVIII in Roman Numerals.
Students often 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 sum of DCCXC and VIII.
The sum of DCCXC and VIII is DCCXCVIII.
DCCXC is 790 and VIII is 8.
The sum of DCCXC and VIII is 790 + 8 = 798.
798 in Roman Numerals can be written as DCCXCVIII.
A library has DCCXCVIII books, and they want to distribute them equally among VI shelves. How many books will each shelf have?
Each shelf will have CXXXIII books.
To find the number of books per shelf, divide the total number of books by the number of shelves.
DCCXCVIII = 798
VI = 6
798 / 6 = 133
133 in Roman Numerals is CXXXIII.
Find the difference between M and CCII.
The difference between M and CCII is DCCXCVIII.
M is 1000, and CCII is 202.
Subtracting these gives: 1000 - 202 = 798
798 in Roman Numerals is DCCXCVIII.
A historian found DCCXCVIII coins buried in the ground. If he divides them into piles of L each, how many piles will he have?
He will have XV piles.
Divide the total number of coins by the size of each pile.
DCCXCVIII = 798
L = 50
798 / 50 = 15
15 in Roman Numerals is XV.
Express the result of multiplying XLIX and XVI in Roman numerals.
The result is DCCXCVIII.
First, convert XLIX and XVI into numbers.
XLIX = 49
XVI = 16
Multiply the numbers: 49 × 16 = 784
784 in Roman Numerals is DCCLXXXIV.
