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.

What is 1998 in Roman Numerals?

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 Roman Numerals. Earlier, people used 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.

In Roman Numerals, we use MCMXCVIII to represent 1998, where M is 1000, CM is 900, XC is 90, and VIII is 8. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 1998 in Roman Numerals

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.

Rule 1: Addition Method

The addition method is used when the smaller number is placed after the larger number. For example, VIII → V + III → 5 + 3 = 8

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.

Rule 3: Subtraction Method

If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, XC → C - X → 100 - 10 = 90

Rule 4: Limitation Rule

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.

How to Write 1998 in Roman Numerals

Let’s now learn how to write 1998 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

1998 in Roman Numerals by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 1998 in Roman numerals using the expansion method.

To write 1998 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc. For 1998, we write it as 1000 + 900 + 90 + 8

Step 2: Convert the number into Roman Numerals

1000 in Roman Numeral — M

900 in Roman Numeral — CM

90 in Roman Numeral — XC

8 in Roman Numeral — VIII

Step 3: Combine these Roman Numerals together.

Therefore, 1998 in Roman Numeral is M (1000) + CM (900) + XC (90) + VIII (8) = MCMXCVIII

1998 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals, we group the number.

To write 1998 in Roman Numerals, we group 1998 as 1000 + 900 + 90 + 8

1000 in Roman Numeral — M

900 in Roman Numeral — CM

90 in Roman Numeral — XC

8 in Roman Numeral — VIII

So, 1998 is written as MCMXCVIII in Roman Numerals.

Common Mistakes and How to Avoid Them in 1998 Roman Numerals

Students often 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.

Problem 1

Calculate the sum of MCM and XCVIII.

Okay, lets begin

The sum of MCM and XCVIII is MCMXCVIII.

Explanation

To find the sum of MCM and XCVIII, convert them to numbers first:

MCM = 1900,

XCVIII = 98.

1900 + 98 = 1998.

1998 in Roman Numerals is MCMXCVIII.

Well explained 👍

Problem 2

A historian found MCMXCVIII ancient coins and wants to distribute them evenly among IIIV collectors. How many coins will each collector receive?

Okay, lets begin

Each collector will receive CCLXIV coins.

Explanation

To find out how many coins each collector receives, divide the total number of coins by the number of collectors:

MCMXCVIII = 1998

IIIV = 7.

1998 / 7 = 264.

264 in Roman Numerals is CCLXIV.

Well explained 👍

Problem 3

Convert the year representing the founding of a city, MCMXLV, and the year of its major renovation, MCMLIII, into Roman Numerals and find their combined total.

Okay, lets begin

The combined total of the years MCMXLV and MCMLIII is MMMCMXCVIII.

Explanation

First, convert the Roman numerals to numbers:

MCMXLV = 1945,

MCMLIII = 1953.

1945 + 1953 = 3898.

3898 in Roman Numerals is MMMCMXCVIII.

Well explained 👍

Problem 4

A museum exhibit displayed MCMXCVIII artifacts and later added XX more. What is the new total of artifacts in Roman Numerals?

Okay, lets begin

The new total of artifacts is MMXVIII.

Explanation

To find the new total, add the additional artifacts to the initial count:

MCMXCVIII = 1998,

XX = 20.

1998 + 20 = 2018.

2018 in Roman Numerals is MMXVIII.

Well explained 👍

Problem 5

Express the year 1998 as a sum of two different Roman numerals and verify the result.

Okay, lets begin

1998 can be expressed as MCM + CMXCVIII.

Explanation

Break down 1998 into two parts: 1900 and 98.

1900 in Roman Numerals is MCM.

98 in Roman Numerals is XCVIII.

MCM + XCVIII = 1998.

Therefore, 1998 is correctly expressed as MCMXCVIII.
