- Roman numerals consist of seven basic symbols: I, V, X, L, C, D, and M, representing 1, 5, 10, 50, 100, 500, and 1000, respectively.
- Symbols are combined to represent different values, with smaller-value symbols appearing to the right of larger-value symbols.
- Symbols may be repeated up to three times in a row, but no more. Exceptions include four of the same symbol (e.g., IV for 4) and nine of the same symbol (e.g., IX for 9).

Subtract V from XXIII:
To subtract V (5) from XXIII (23), we need to understand the subtraction rule in Roman numerals. When a smaller-value symbol appears before a larger-value symbol, it represents subtraction. In this case, we have XXIII (23) - V (5). By subtracting V from XXIII, we remove the value of 5 from 23, resulting in XVIII (18). Therefore, XXIII - V = XVIII.

XXIII Roman Numerals FAQs
Q1: Are Roman numerals still used today?
A1: Yes, Roman numerals are still used today in various domains. They are often seen in the copyright years of movies, on clock faces, in the names of monarchs and popes, and in numbering important events like Super Bowls. Additionally, Roman numerals are sometimes used for decorative or stylistic purposes in design, typography, and branding.
Q2: How do you read large Roman numerals?
A2: Reading large Roman numerals involves understanding the system's rules and principles. The basic rule is to start from the left and add or subtract the values of each symbol to determine the total value. When encountering a smaller-value symbol before a larger-value symbol, subtract the smaller from the larger. To read large Roman numerals more efficiently, it helps to break them down into smaller groups, identify patterns, and apply the rules accordingly.
Q3: What is the highest Roman numeral?
A3: The highest Roman numeral is M, which represents 1000. In ancient Rome, the concept of zero was not part of the numeral system, so there is no symbol for representing zero in Roman numerals. To represent larger numbers, a horizontal line or bar placed above a numeral multiplied its value by 1000. For example, a bar placed above M (represented as M̅) would indicate 1,000,000 (1 million). However, such large numbers are rarely encountered in everyday use of Roman numerals today.
Remember, Roman numerals have specific rules and conventions, and their usage may vary in different contexts.
