718 in Roman Numerals
Roman numerals are a way of expressing numbers using symbols. The symbols I, V, X, L, C, D, and M are used to represent different values. Roman numerals are often seen in royal titles, book names, sequences, and more. In this content, we will discuss Roman numerals, their rules, and examples.
What is 718 in Roman Numerals?
Royal titles such as Henry I, Henry II, and so on use Roman numerals to denote order or succession. In ancient times, people used fingers, sticks, and bones to count.
As societies became more complex, a standardized counting system was developed. The ancient Romans used this numeral system to count. The symbols we use are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
In Roman numerals, we use DCCXVIII to represent 718. Here, D is 500, CC is 200, X is 10, V is 5, and III is 3. Let's learn more about Roman numerals and how we write them.
Basic Rules for 718 in Roman Numerals
There are certain basic rules for writing numbers in Roman numerals. In this section, we will discuss some basic rules to remember when writing a number in Roman numerals.
Rule 1: Addition Method
The addition method is used when a smaller numeral is placed after a larger numeral. For example, XVIII → X + V + III → 10 + 5 + 3 = 18.
Rule 2: Repetition Method
To write larger numbers, certain Roman numerals can be repeated up to three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a smaller numeral precedes a larger numeral, the smaller is subtracted from the larger. For example, IX → X - I → 10 - 1 = 9.
Rule 4: Limitation Rule
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we do not write VV for 10; instead, we use X.
How to Write 718 in Roman Numerals
Let's learn how to write 718 in Roman numerals using different methods.
By Expansion Method
In the expansion method, the number is broken down based on place value. To write 718 in Roman numerals, follow these steps:
Break the number based on place value: hundreds, tens, and ones.
718 = 700 + 10 + 8
Convert each part into Roman numerals:
- 700 is DCC (500 + 200)
- 10 is X
- 8 is VIII (5 + 3)
Combine them:
- Therefore, 718 in Roman numerals is DCCXVIII.
By Grouping Method
For larger numbers, group the number and convert each group:
- 718 is 700 + 10 + 8
- 700 in Roman numerals is DCC
- 10 in Roman numerals is X
- 8 in Roman numerals is VIII
- So, 718 is written as DCCXVIII.
