Roman Numerals

Over two thousand years ago, roman numerals were created and they are still used during this day and age. It’s interesting to know that something that was created such a long time ago still has it’s place in our world today. Many modern appliances and other things use roman numerals in place of numbers for various purposes, such as the numbering system used on the faces of many different clocks and watches. Building inscriptions, different magazines, monuments, official papers, and various books also sometimes have roman numerals on them in place of numbers.

The way that the system of roman numerals works is by using letters in place of numbers. There are seven different letters being used in place of numbers. They can be used by themselves or in different combinations with each other to represent all of the different numbers. If a bar happens to be placed over top of the roman numeral, then that means that you need to multiply the value of the roman numeral by one thousand.

The seven different letters being used in the system of roman numerals are I, V, X, L, C, D, and M. the letter “I” is the roman numeral that is used in place of 1, V is the roman numeral that is used in place of 5, X is the roman numeral that is used in place of 10, L is the roman numeral that is used in place of 50, C is the roman numeral that is used in place of 100, D is the roman numeral that is used in place of 500, and M is the roman numeral that is used in place of 1,000.

II is the roman numeral that is equal to 2 and III is equal to 3. When a letter that represents a lesser number is on the left side of a letter representing a greater number, you must subtract the lesser number from the greater number to find out what that roman numeral stands for. For example, in the roman numeral IV, I stands for 1 and V stands for 5. If you subtract 1 from 5, the answer is 4. Therefore, the roman numeral for IV is equal to 4.
