Roman numerals are a way of expressing numbers using specific symbols. The symbols used in Roman numerals are I, V, X, L, C, D, and M. Roman Numerals are often found in royal titles, book names, sequences, and more. Here, we will explore Roman Numerals, the rules governing them, and their examples.
Royal titles, such as Henry I, Henry II, and so on, often use Roman Numerals. You might have wondered what these symbols (I and II) represent. They are Roman Numerals.
In ancient times, people counted using fingers, sticks, bones, etc. As life became more complex, a standard form of counting was needed. The ancient Romans developed the Roman Numeral system to fulfill this need. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in counting.
In Roman Numerals, we use CXLVI to represent 146. Here, C is 100, XL is 40, and VI is 6. Let’s learn more about Roman numerals and how we write them.
Here’s the breakdown of Roman numerals for 146 in the requested format: ``` CXL = 100 + 40 = 140 CXLI = 100 + 40 + 1 = 141 CXLII = 100 + 40 + 2 = 142 CXLIII = 100 + 40 + 3 = 143 CXLIV = 100 + 40 + 4 = 144 CXLV = 100 + 40 + 5 = 145 CXLVI = 100 + 40 + 5 + 1 = 146
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, VI → V + I → 5 + 1 = 6.
To write larger numbers, certain Roman Numerals can be repeated up to three times. For example, XXX → 30.
If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40.
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, 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 146 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 146 in Roman numerals using the expansion method.
To write 146 in Roman Numerals, follow these steps:
Step 1: Break the number based on place value: hundreds, tens, and ones.
For 146, we write it as 100 + 40 + 6.
Step 2: Convert the numbers into Roman Numerals:
- 100 in Roman Numerals — C
- 40 in Roman Numerals — XL
- 6 in Roman Numerals — VI
Step 3: Combine the Roman Numerals together:
- Therefore, 146 in Roman Numerals is C (100) + XL (40) + VI (6) = CXLVI.
When writing a large number into Roman Numerals, we group the number. To write 146 in Roman Numerals, we group 146 as 100 + 40 + 6:
- 100 in Roman Numerals — C
- 40 in Roman Numerals — XL
- 6 in Roman Numerals — VI
So, 146 is written as CXLVI in Roman Numerals.
A historian is cataloging ancient artifacts and finds two chests. One contains CXLVI coins, and the other contains LXXIII coins. How many coins are there in total?
A library is organizing its collection and has CCLXXXVIII books, which need to be divided equally amongst II sections. How many books will each section have?
An archaeologist discovers two scrolls dating back to ancient times. One scroll is dated CXLVI years before the current era, and the other is dated XCVI years after that. What is the total number of years between the present and the older scroll?
A historian examines two ancient texts. One text mentions an event happening CLX years ago, and another mentions an event that occurred XIV years after that. How many years ago did the second event occur?
