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 more. Here we will be discussing Roman numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are Roman numerals. Initially, 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 DCCVI to represent 706, where D is 500, CC is 200, and VI is 6.
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, indicating addition. For example, DCCVI → D + CC + V + I → 500 + 200 + 5 + 1 = 706.
To write a larger number, certain Roman numerals can be repeated up to three times. For example, CCC → 300.
If a smaller number is followed by a larger number in Roman numerals, we subtract the smaller number from the larger number. 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, for 10, we won't write VV; instead, we use X.
Let’s now learn how to write 706 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 706 in Roman numerals using the expansion method. To write 706 in Roman numerals, follow these steps:
Step 1: Break down the number based on the place value: ones, tens, hundreds, etc. For 706, we write it as 700 + 6.
Step 2: Converting the numbers into Roman numerals:
Step 3: Combine the Roman numerals together: Therefore, 706 in Roman numeral is DCC (700) + VI (6) = DCCVI.
When writing a large number into Roman numerals, we group the number. To write 706 in Roman numeral, we group 706 as 700 + 6.
So, 706 is written as DCCVI 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 sum of DCCVI and LXXXIV.
The sum of DCCVI and LXXXIV is DCCCXC.
In Roman numerals, DCCVI is 706 and LXXXIV is 84.
The sum of these numbers is 706 + 84 = 790.
790 in Roman numerals is DCCCXC.
A historian is organizing DCCVI ancient artifacts into XIV categories. How many artifacts will go into each category?
Each category will have LI artifacts.
To find the number of artifacts per category, divide the total number of artifacts by the number of categories.
DCCVI = 706
XIV = 14
So, 706 / 14 = 51.
51 in Roman numerals is LI.
Find the product of DCCVI and II.
The product of DCCVI and II is MCDXII.
In Roman numerals, DCCVI is 706 and II is 2.
The product of these numbers is 706 × 2 = 1412.
1412 in Roman numerals is MCDXII.
What is the difference between DCCVI and CLIV?
The difference between DCCVI and CLIV is DLII.
The difference between two numbers is found by subtracting one from the other.
DCCVI = 706
CLIV = 154
706 - 154 = 552
552 in Roman numerals is DLII.
Express 706 as a sum of Roman numerals using the expansion method.
The expression of 706 using the expansion method is DCC + VI.
Step 1: Break down 706 into its components. 700 is DCC, and 6 is VI. So, 706 = 700 + 6 = DCC + VI.
