Roman numerals have been around for centuries, used to represent numbers in the classical world and now used to denote the hours on clocks, or to number lists and outlines. The basic Roman numerals are I, V, X, L, C, D, and M, and these seven symbols can be combined to create any number. Counting in Roman numerals is not as difficult as it may seem, and with a little practice, you can become a master of this ancient numerical system.
The Basics of Roman Numerals
Roman numerals are written in descending order, meaning that the largest number is written first, with the rest of the numbers following in descending order. For example, the number 4 would be written as IV, meaning 1 (I) followed by 5 (V). Roman numerals do not use negative numbers, fractions, or decimals, but they can represent very large numbers. The largest number that can be represented in Roman numerals is 3,999 which is written as MMMCMXCIX.
Combining Roman Numerals
Roman numerals are combined in various ways depending on the number. The most basic combination is to simply add the numbers together, so 2 would be written as II, 3 would be written as III, 4 would be written as IV, and so on. Roman numerals are also combined by subtracting a smaller number from a larger one. For example, 4 would be written as IV, meaning 5 (V) minus 1 (I).
Roman Numeral Principles
Roman numerals also have a few principles to follow when writing them. The first principle is that a symbol can only be used three times in a row before it must be replaced with a larger one. For example, the number 4 cannot be written as IIII, it must be written as IV. The second principle is that a symbol can only be subtracted from the one that is 10 times larger, so 4 cannot be written as IL, it must be written as IV. The third principle is that only one symbol can be subtracted from a number. For example, the number 5 cannot be written as IVV, it must be written as V.
Roman Numeral Examples
Now that you understand the basics of Roman numerals and the principles behind them, let’s look at some more examples. The number 6 would be written as VI, meaning 5 (V) plus 1 (I). The number 7 would be written as VII, meaning 5 (V) plus 2 (II). The number 8 would be written as VIII, meaning 5 (V) plus 3 (III). The number 9 would be written as IX, meaning 10 (X) minus 1 (I). The number 10 would be written as X.
Counting in Roman Numerals
Counting in Roman numerals can be tricky, but with a few simple guidelines, you’ll be a pro in no time. The most important thing to remember is that Roman numerals are written in descending order. The largest number is always written first, and then the rest of the numbers are written in descending order. Once you have mastered the basics, counting in Roman numerals can become second nature.
