Roman numerals are the 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 the 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 we use to count.
In Roman Numerals, we use DCLXXIV to represent 674. Here, D is 500, C is 100, L is 50, X is 10, 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 a smaller number is placed after a larger number. For example, DCLXXIV → D + C + L + X + X + IV → 500 + 100 + 50 + 10 + 10 + 4 = 674
To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, XX → 20 (X is repeated twice).
If a smaller number is placed before a larger number in Roman Numerals, we subtract the smaller number from the larger one. 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 VV for 10; instead, we use X. For 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 674 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 674 in Roman numerals using the expansion method. To write 674 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 674, we write it as 600 + 70 + 4
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 674 in Roman Numerals is DC (600) + LXX (70) + IV (4) = DCLXXIV
When writing a large number into Roman Numerals, we group the number. To write 674 in Roman Numerals, we group 674 as 600 + 70 + 4
So, 674 is written as DCLXXIV in Roman Numerals.
Students often make mistakes when writing numbers in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
What is the sum of DCLXXIV and CXXVI?
The sum of DCLXXIV and CXXVI is DCCC
DCLXXIV is 674
CXXVI is 126.
Adding these together:
674 + 126 = 800.
The Roman numeral for 800 is DCCC.
A library has a collection of DCLXXIV ancient manuscripts and plans to distribute them equally among II schools. How many manuscripts will each school receive?
Each school will receive CCCXXXVII manuscripts.
DCLXXIV equals 674,
II equals 2.
Dividing 674 by 2 gives 337.
CCCXXXVII is the Roman numeral for 337.
A historian finds that the difference between the number of relics in two collections is DCCXXIV. If one collection has MMMCD relics, how many relics does the other collection have?
The other collection has MMMDCLXXVI relics.
DCCXXIV is 724.
MMMCD is 3400.
Therefore, the other collection has 3400 - 724 = 2676 relics.
The Roman numeral for 2676 is MMMDCLXXVI.
Convert the multiplication of XLVII and XIV into Roman numerals.
The result of multiplying XLVII and XIV is DCLXVIII.
XLVII is 47 and XIV is 14.
Multiplying these gives 47 × 14 = 658
In Roman numerals, 658 is written as DCLVIII.
A monument inscription has a date written as DCLXXIV. Convert this date to the modern calendar year.
The date DCLXXIV corresponds to the year 674.
DCLXXIV in Roman numerals is 674 when converted to Arabic numerals.
Thus, the monument's date is the year 674.
