The Roman numeral XC stands for the number 90. This numeral is a combination of two values: X (10) and C (100). In Roman numeral conventions, placing a smaller numeral before a larger one signifies subtraction, so XC is 100 – 10, which equals 90. Understanding Roman numerals can be beneficial for various applications, including reading historical documents and understanding classical literature.

Understanding Roman Numerals

Roman numerals are a numeral system originating from ancient Rome. They use combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M. These symbols represent different values and can be combined to form other numbers.

Application in Modern Times

Conversion Techniques

To convert Roman numerals to Arabic numerals, one must understand the basic values and their combinations. For example, XC is broken down into 100 (C) minus 10 (X), which equals 90. Familiarity with this conversion process is useful for educational and historical purposes.

In summary, Roman numeral XC represents the number 90 through a combination of subtraction. Knowledge of Roman numerals enhances one’s ability to interpret historical and contemporary references accurately.
