Roman numerals are a way of expressing numbers using symbols like I, V, X, L, C, D, and M. Roman Numerals are used in various contexts such as royal titles, book names, sequences, and more. Here we will discuss Roman Numerals, their rules, and examples.
The royal titles, such as Henry I, Henry II, etc., use Roman Numerals. These symbols like I and II represent numbers.
Earlier, people counted using fingers, sticks, bones, etc., but as life became complex, a standardized form was needed. Ancient Romans used Roman Numerals to count. We use I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) to count.
In Roman Numerals, 774 is represented as DCCLXXIV. Here, D is 500, CC is 200, L is 50, XX is 20, and IV is 4. 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, DCCLXXIV → D (500) + CC (200) + L (50) + XX (20) + IV (4) = 774
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
If a small number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4
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 DDD for 1500; instead, we use MD.
Let’s now learn how to write 774 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 774 in Roman numerals using the expansion method. To write 774 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc. For 774, we write it as 700 + 70 + 4.
Step 2: Convert the number into Roman Numerals.
Step 3: Combine the Roman Numerals together. Therefore, 774 in Roman Numerals is DCC (700) + LXX (70) + IV (4) = DCCLXXIV
When writing a large number into Roman Numerals, we group the number. To write 774 in Roman Numerals, we group 774 as 700 + 70 + 4.
700 in Roman Numeral - DCC
70 in Roman Numeral - LXX
4 in Roman Numeral - IV
So, 774 is written as DCCLXXIV in Roman Numerals.
Calculate the sum of DCCXXIV and L.
A historian has access to a collection of DCCLXXIV manuscripts. If each archive box can hold XX manuscripts, how many full boxes can the historian fill?
A museum exhibit features a timeline that jumps from CCC to DCCLXXIV. How many years are missing from the timeline?
Determine the Roman numeral representation of the difference between M and CCXXVI.
Write the Roman numeral for 700 + 74 using the expansion method.
