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 DCCXXXVIII to represent 738, where D is 500, CC is 200, XXX is 30, and VIII is 8.
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, VIII → V + I + I + I → 5 + 1 + 1 + 1 = 8
To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, XXX → 10 + 10 + 10 = 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, 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 as VIII, not IIIIIIII.
Let’s now learn how to write 738 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 738 in Roman numerals using the expansion method. To write 738 in Roman Numerals, follow the steps,
Step 1: The number is broken based on the place value: ones, tens, hundreds, etc. For 738, we write it as 700 + 30 + 8
Step 2: Converting the number into Roman Numerals
Step 3: Combining the Roman Numerals together. Therefore, 738 in Roman Numerals is DCC (700) + XXX (30) + VIII (8) = DCCXXXVIII
When writing a large number into Roman Numerals, we group the numbers. To write 738 in Roman Numerals, we group 738 as 700 + 30 + 8
So, 738 is written as DCCXXXVIII in Roman Numerals.
Calculate the sum of the Roman numerals CCCXXXVIII and CD.
A historian found DCCXXXVIII ancient coins and wants to display them in VIII rows equally. How many coins will each row have?
If you subtract CCCL from DCCXXXVIII, what Roman numeral do you get?
A puzzle game requires forming the number 738 using Roman numeral tiles. If you already have CDXXXVIII, what numeral do you need to reach 738?
Write the Roman Numeral for 738 using the expansion method.
