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 (I and II) represented? Those are Roman Numerals. Earlier 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 used to count.
In Roman Numerals, we use DCCXCV to represent 795, where D is 500, CC is 200, XC is 90, and V is 5. 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. For example, VI → V + I → 5 + 1 = 6
To write a large number, certain Roman Numerals can be repeated three times. III → 3.
If a small number is placed before a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9
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 795 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 795 in Roman numerals using the expansion method.
To write 795 in Roman Numerals, follow these steps:
Step 1: The number is broken down based on the place value, i.e., hundreds, tens, and ones. For 795, we write it as 700 + 90 + 5
Step 2: Converting the number into Roman Numerals
Step 3: Combining the Roman Numerals together. Therefore, 795 in Roman Numerals is DCC (700) + XC (90) + V (5) = DCCXCV
When writing a large number into Roman Numerals, we group the number. To write 795 in Roman Numerals, we group 795 as 700 + 90 + 5
So, 795 is written as DCCXCV 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 DL and CCXLV.
The sum of DL and CCXLV is DCCXCV.
DL is 550 and CCXLV is 245.
The sum of DL and CCXLV is 550 + 245 = 795.
795 in Roman Numerals is DCCXCV.
A historian is cataloging DCCXCV ancient coins into V equal groups. How many coins will each group contain?
Each group will contain CLIX coins.
To find the number of coins in each group, we divide the total number of coins by the number of groups.
DCCXCV = 795
V = 5 795 / 5 = 159
159 in Roman Numerals is CLIX.
Find the difference between M and CCV.
The difference between M and CCV is DCCXCV.
The difference is obtained by subtracting the smaller number from the larger one.
M = 1000
CCV = 205
1000 - 205 = 795
795 in Roman Numerals is DCCXCV.
If a marathon runner completes DCCXCV meters twice, how many meters has the runner covered in total?
The runner has covered MDLXXXX meters in total.
To find the total distance, multiply the distance covered once by the number of times.
DCCXCV = 795
795 × 2 = 1590
1590 in Roman Numerals is MDLXXXX.
Express the number 795 in Roman Numerals using addition.
The Roman numeral for 795 using addition is DCC + XC + V.
Break down 795 into its components: 700 + 90 + 5
700 = DCC
90 = XC
5 = V
Therefore, 795 = DCC + XC + V = DCCXCV.
