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, use Roman Numerals. Have you noticed the names and wondered what these symbols represent? Those are the Roman Numerals. In ancient times, people used fingers, sticks, and bones to count. As life became more complex, a standardized form was required.
The Roman Numeral system was developed by the ancient Romans for this purpose. The symbols used are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman Numerals, we use CMLXX to represent 970, where CM is 900, L is 50, and XX is 20.
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 a smaller number is placed after a larger number; then, it is the addition method. For example, LXX → L + X + X → 50 + 10 + 10 = 70
To write a large number, certain Roman Numerals can be repeated up to three times. XXX → 30.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, CM → M - C → 1000 - 100 = 900
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 970 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 970 in Roman numerals using the expansion method. To write 970 in Roman Numerals, follow the steps,
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 970, we write it as 900 + 70
Step 2: Converting the numbers into Roman Numerals
Step 3: Combining them together. Therefore, 970 in Roman Numeral is CM (900) + LXX (70) = CMLXX
When writing a large number into Roman Numerals, we group the number. To write 970 in Roman Numerals, we group 970 as 900 + 70
So, 970 is written as CMLXX 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 ways to avoid them.
A historian finds two ancient artifacts marked with numbers CM and LXX. What is the sum of these numbers in Roman numerals?
The sum of CM and LXX is CMLXX.
CM represents 900 and LXX represents 70. The sum is 900 + 70 = 970. Therefore, 970 in Roman numerals is written as CMLXX.
An art collector has DXL paintings and wants to distribute them evenly among five galleries. How many paintings will each gallery receive in Roman numerals?
Each gallery will receive CXVIII paintings.
To determine the number of paintings each gallery receives, divide the total number of paintings (DXL) by the number of galleries (5).
DXL = 540
540 / 5 = 108
108 in Roman numerals is CXVIII.
A scholar translates an ancient text that adds DCCC and CLXX. What is the result in Roman numerals?
The sum of DCCC and CLXX is CMLXX.
DCCC equals 800, and CLXX equals 170. Adding them gives 800 + 170 = 970. Thus, the sum in Roman numerals is CMLXX.
A mathematician subtracts XXX from M. What is the result in Roman numerals?
The result of subtracting XXX from M is CMLXX.
M is 1000 and XXX is 30. The difference is 1000 - 30 = 970. Therefore, in Roman numerals, the result is CMLXX.
Convert the number 970 into Roman numerals using the expansion method.
970 in Roman numerals is CMLXX.
Step 1: Break down the number 970. 970 = 900 + 70 Step 2: Convert each part to Roman numerals.
900 = CM
70 = LXX
Combine them to get CMLXX.
