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 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. 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.
To represent 1971 in Roman Numerals, we use MCMLXXI, where M is 1000, CM is 900, LXX is 70, and I is 1. Let’s learn more about Roman numerals and how we write them.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, XI → X + I → 10 + 1 = 11.
To write a large number, certain Roman Numerals can be repeated three times. III → 3.
If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number. 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, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 1971 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 1971 in Roman numerals using the expansion method. To write 1971 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values include thousands, hundreds, tens, and ones. For 1971, we write it as 1000 + 900 + 70 + 1.
Step 2: Convert the numbers into Roman Numerals:
Step 3: Combine the Roman Numerals: Therefore, 1971 in Roman Numerals is M (1000) + CM (900) + LXX (70) + I (1) = MCMLXXI.
When writing a large number in Roman Numerals, we group the numbers. To write 1971 in Roman Numerals, we group 1971 as 1000 + 900 + 70 + 1.
So, 1971 is written as MCMLXXI in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian discovers that the year MCMLXXI marked significant events. Calculate the number of years since MCMLXXI to 2023.
The number of years from MCMLXXI to 2023 is LII.
To calculate the years between 1971 and 2023: 1971 in Roman numerals is MCMLXXI.
2023 - 1971 = 52.
52 in Roman numerals is LII.
An archaeologist finds a relic dated MCMLXXI and wants to place it between two other relics dated MCMXLIV and MMVI. Determine the chronological order of the relics.
The chronological order is MCMXLIV, MCMLXXI, MMVI.
MCMXLIV is 1944, MCMLXXI is 1971, and MMVI is 2006 in Roman numerals.
Hence, the order from earliest to latest is 1944, 1971, 2006.
A collector has a coin from the year MCMLXXI and another from the year MMXXI. Find the difference in years between the two coins.
The difference in years between MCMLXXI and MMXXI is L.
MCMLXXI represents 1971, and MMXXI represents 2021 in Roman numerals.
2021 - 1971 = 50.
50 in Roman numerals is L.
A document references events from MCMLXXI and MCMXCIX. How many years apart are these events?
The events in MCMLXXI and MCMXCIX are XXVIII years apart.
MCMLXXI is 1971 and MCMXCIX is 1999 in Roman numerals.
1999 - 1971 = 28. 28 in Roman numerals is XXVIII.
Translate the year MCMLXXI into the sum of its Roman numeral components.
The sum of the Roman numeral components of MCMLXXI is M + CM + L + X + X + I.
MCMLXXI is 1971 in Roman numerals. M = 1000, CM = 900, L = 50, X = 10, X = 10, I = 1.
Thus, 1000 + 900 + 50 + 10 + 10 + 1 = 1971.
The Roman numeral components are M + CM + L + X + X + I.
