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 DCCCL to represent 850, where D is 500, CCC is 300, and L is 50. 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. For example, DCCCL → D + CCC + L → 500 + 300 + 50 = 850
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, XL → L - X → 50 - 10 = 40.
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.
Let’s now learn how to write 850 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 850 in Roman numerals using the expansion method.
To write 850 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place values include ones, tens, hundreds, etc. For 850, we write it as 500 + 300 + 50.
Step 2: Converting the number into Roman Numerals
500 in Roman Numeral — D
300 in Roman Numeral — CCC
50 in Roman Numeral — L
Step 3: Combining the Roman Numerals together.
Therefore, 850 in Roman Numerals is D (500) + CCC (300) + L (50) = DCCCL.
When writing a large number into Roman Numeral, we group the number.
To write 850 in Roman Numerals, we group 850 as 500 + 300 + 50.
500 in Roman Numeral — D
300 in Roman Numeral — CCC
50 in Roman Numeral — L
So, 850 is written as DCCCL in Roman Numerals.
Calculate the difference between DCCC and L.
A historian discovers DCCCXL ancient coins. If they distribute these coins equally among X archaeologists, how many coins does each archaeologist receive?
If a merchant has two chests containing CDXL and CDX coins respectively, what is the total number of coins?
A marathon course is CCL kilometers long. If a runner completes the course D times, what is the total distance covered?
Express the sum of DCL and CCXL using the expansion method in Roman Numerals.
