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. 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 DCCLXXXVI to represent 786, here D is 500, CC is 200, L is 50, XXX is 30, and VI is 6. 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, then it is the addition method. For example, VI → V + I → 5 + 1 = 6
To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. It is a subtraction method. 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. Similarly, for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 786 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 786 in Roman numerals using the expansion method. To write 786 in Roman Numerals, follow the steps:
Step 1: The number is broken down based on the place value. Place values are ones, tens, hundreds, etc. For 786, we write it as 700 + 80 + 6
Step 2: Converting the numbers into Roman Numerals:
Step 3: Combining the Roman Numerals together: Therefore, 786 in Roman Numerals is DCC (700) + LXXX (80) + VI (6) = DCCLXXXVI
When writing a large number into Roman Numerals, we group the numbers. To write 786 in Roman Numerals, we group 786 as 700 + 80 + 6
So, 786 is written as DCCLXXXVI in Roman Numerals.
Calculate the sum of DCCLXXX and VI.
A historian found a document stating a king ruled for DCC years and his son ruled for LXXXVI years. What was the total length of their reigns?
A museum has a collection of DCCXC artifacts, and plans to add a collection of IX more. How many artifacts will the museum have in total?
A marathon runner completed a distance of DCCL miles and has LXXXVI miles remaining. What is the total distance of the marathon?
Convert the sum of CDLXX and CCCXVI to Roman numerals using the expansion method.
