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 more. Here we will be discussing Roman numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are Roman numerals.
Earlier people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required for counting. Ancient Romans developed the Roman numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used for counting.
In Roman numerals, we use DCLXII to represent 662. Here, D is 500, C is 100, L is 50, X is 10, and II is 2. 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, LXII → L + X + I + I → 50 + 10 + 1 + 1 = 62
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 larger 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, and for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 662 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, the number is broken down based on the place value. In this section, we will learn how to write 662 in Roman numerals using the expansion method. To write 662 in Roman numerals, follow the steps:
Step 1: Break the number based on the place value, which includes units, tens, hundreds, etc. For 662, we write it as 600 + 60 + 2.
Step 2: Converting the number into Roman numerals 600 in Roman numerals - DC 60 in Roman numerals - LX 2 in Roman numerals - II
Step 3: Combining these Roman numerals together. Therefore, 662 in Roman numerals is DC (600) + LX (60) + II (2) = DCLXII
When writing a large number in Roman numerals, we group the number. To write 662 in Roman numerals, we group it as 600 + 60 + 2.
So, 662 is written as DCLXII in Roman numerals.
Determine the sum of DCLXII and XXXVIII.
A library has DCLXII books and plans to distribute them evenly among VI schools. How many books will each school receive?
