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.
