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. Have you noticed the 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. to count earlier. 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 CMLXXIII to represent 973, here CM is 900, L is 50, XX is 20, and III is 3.
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, then it is the addition method. For example, LXXIII → L + X + X + I + I + I → 50 + 10 + 10 + 1 + 1 + 1 = 73
To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.
If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number, it is the subtraction method. 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 DDDD for 2000; instead, we use MM, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 973 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 973 in Roman numerals using the expansion method. To write 973 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 973, we write it as 900 + 70 + 3.
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 973 in Roman Numeral is CM (900) + LXX (70) + III (3) = CMLXXIII
When writing a large number into Roman Numeral, we group the number. To write 973 in Roman Numeral, we group 973 as 900 + 70 + 3.
So, 973 is written as CMLXXIII 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 the ways to avoid them.
Calculate the sum of CDLXII and DXI.
The sum of CDLXII and DXI is CMLXXIII.
CDLXII is 462 and DXI is 511. The sum of CDLXII and DXI is 462 + 511 = 973. 973 in Roman Numerals can be written as CMLXXIII.
A historian is categorizing CMLXXIII artifacts equally among XIII different exhibitions. How many artifacts will each exhibition receive?
Each exhibition will receive LXXV artifacts.
To find the number of artifacts per exhibition, divide the total number of artifacts by the number of exhibitions. CMLXXIII = 973
XIII = 13
973 / 13 = 75.
75 in Roman numerals is LXXV.
Find the difference between MXX and XLVII.
The difference between MXX and XLVII is CMLXXIII.
The difference is found by subtracting one number from the other.
MXX = 1020
XLVII = 47
1020 - 47 = 973.
973 in Roman Numerals is CMLXXIII.
What is the product of X and XCVII?
The product of X and XCVII is CMLXX.
The product is the result of multiplying two numbers.
X = 10
XCVII = 97
10 × 97 = 970.
970 in Roman Numerals is CMLXX.
Convert 973 into Roman Numerals using the expansion method.
973 in Roman Numerals is CMLXXIII.
Step 1: Break down 973 into its parts: 900, 70, and 3.
900 = CM
70 = LXX
3 = III
Step 2: Combine them to get the Roman numeral: CM + LXX + III = CMLXXIII.
