Roman numeral, any of the symbols used in a system of numerical notation based on the ancient Roman system. The symbols are I, V, X, L, C, D, and M, standing respectively for 1, 5, 10, 50, 100, 500, and 1,000 in the Hindu-Arabic numeral system.
So, how do you know when to add or subtract letters when working out what number the Roman numeral equation represents? The simple answer is that a number needs to be subtracted if it appearsbeforea larger one. For this, you will need to refer to the chart of the seven letters used in...
Roman numbers are a unique numeral system originating in ancient Rome. These numbers have remained in Europe until the Late Middle Ages. Alphabet letters are used in this system to represent Roman numerals. Before understanding the Roman numbers, first, see what Roman alphabets are because Roman ...
Roman numerals can be easily read by expanding them. Then, we substitute the respective values and add or subtract them accordingly. For example, let us read the Roman numeral, VII. After expanding this, we get, V + I + I. After substituting the values as V = 5, I = 1, we get 5...
Problem Examples for XXI Roman NumeralsHere are a few examples of Roman numeral conversion problems involving XXI:Example 1: Convert XLIII to an Arabic decimal number. To solve this problem, we need to break down the Roman numeral into its individual symbols and calculate their values. XLIII ...
Example 1: Add the following: Roman numeral MMXX + XII. Solution: MMXX = 2020, and XII = 12 ⇒ MMXX + XII = 2020 + 12 = 2032 ⇒ The sum is 2032, which can be written as MMXXXII Example 2: Find the difference between MMXX and MDCXCIX. Solution: Roman Numeral MMXX is equal...

The Roman Numeral system was obviously pretty unwieldy and an evident shortcoming of it is the lack of simple means of defining larger numbers, possibly suggesting that the Romans had little need for such large arithmetic. God knows how they managed to undertake those amazing feats of engineering...
