Roman Numerals

Roman numerals are a numeral system that originated in ancient Rome. They are still used today in certain contexts, such as on clock faces and in the names of monarchs and popes.

Basic Roman Numerals

The basic Roman numerals are I, V, X, L, C, D, and M. These symbols represent the numbers 1, 5, 10, 50, 100, 500, and 1000, respectively.

Subtraction in Roman Numerals

In Roman numerals, subtraction is often used to represent numbers that are not easily represented by a single symbol. To subtract a smaller number from a larger number, a smaller symbol is placed before a larger symbol. For example, to represent the number 4, the symbol IV is used, which means 5 - 1.

Roman Numeral That Cannot Be Subtracted

The Roman numeral V (5) can never be subtracted. This is because the symbols used in Roman numerals are arranged in a specific order, from largest to smallest. A smaller symbol can only be placed before a larger symbol to represent subtraction. Since V (5) is already smaller than X (10), it cannot be subtracted from any larger numeral.

Conclusion

In conclusion, the basic Roman numeral that can never be subtracted is V (5). Roman numerals are still used today in certain contexts, and understanding their basic principles can be helpful in deciphering their meaning.

The symbols V, L and D are not written to the left of a symbol that has greater value. This means that V, L and D are never subtracted.
