## What Are Roman Numerals?

Roman numerals as the name implies can be traced back to the Ancient Roman Empire. The Roman numerals numbering system has been used by most Europeans for over 1800 years. This simply means that the Roman numbering system is older than the present Hindu-Arabic system of numbering which is predominantly used today.

## XXVIII Roman Numerals

Remember that I have stated earlier in the introduction, that XXVIII Roman numerals is the representation of the number ** 28**.

But in this section, we are going to look at how to convert Roman numerals to Hindu Arabic numbers and vice versa.

For easy comprehension, I have decided to summarize the conversion process in the table below. All you have to do is to pay keen attention and I bet you that you will get the gist easily. Let’s go

Thousands | Hundreds | Tens | Ones | |

Arabic
Numerals |
2 | 8 | ||

0 | ||||

1 | M | C | X | I |

2 | MM | CC | XX | II |

3 | MMM | CCC | XXX | III |

4 | CD | XL | IV | |

5 | D | L | V | |

6 | DC | LX | VI | |

7 | DCC | LXX | VII | |

8 | DCCC | LXXX | VIII | |

9 | CM | XC | IX | |

From the table above, we can see that 2 is under the Tens column and 8 is under the One’s column. From the table now, we see that the second row in the ten’s column has Roman numerals of XX while the eighth row on the one’s column contains VIII. Hence when you add the two together i.e XX + VIII, you will get XXVIII which is equal to 28 in Hindu Arabic form. And that’s all

Meanwhile, if you want to convert from Arabic to Roman numerals or vice versa. Simply put the number as in the above table, and definitely, the number will appear in the exact form that you want it to be. However, due to the limitations of the Roman numbering system, it is only possible to convert numbers from 1 to 3999.

However, to be able to convert Roman and Arabic numerals using the table above, you have to handle one Arabic digit at a time and then translate it to the right Roman number. But when using the table, it is pertinent for you to note that both the column and row for zeroes are usually empty, so ensure that your table is properly fixed before you start the conversion to avoid making mistakes.

Once you draw your table properly as the one above and tackle one Arabic digit at a time, I assure you that you will get the right answer when you carry out any other conversion.

### The Major Roman Symbols Used To Represent Arabic Numbers

- First Method

In this first method, we have to break the Roman numerals into single letters, then write the numerical value of each letter and after that, you can either subtract or add them.

The illustration is below

XXVIII= X + X + V + I + I + I = 10 + 10 + 5 + 1 + 1 + 1 = 28

- Second Method

## Rules For Converting Roman Numerals

All the known Roman numerals consist of a set of seven symbols. These combinations follow four vital principles. Hence, you must Know and adhere to these four key rules when converting Roman numerals.

Hence, this section is designed to guide you on what the rules are, and how it works with their application attached to enable you to use them without making mistakes.

- First Rule

This rule states that when a smaller symbol is after a great symbol, it is added.

The examples can be seen below;

- XVII = 10 + 5 + 2= 17
- LVIII = 50 + 5 = 58

- Second Rule

This rule says that when a smaller symbol appears before a greater symbol, it should be subtracted

Some of the examples are outlined below

- IX = 10 – 1 = 9
- XXL= 50 – 10 – 10 = 30
- CCM = 1000 – 100 – 100 = 800

- Third Rule

This rule states that the same symbol cannot be repeated more than three times in a row.

The examples can be seen below

- XXX = 10 + 10 + 10 = 30, hence 40 is not XXXX instead it is XL.
- CCC = 100 + 100 + 100 = 300, but 400 is not CCCC. Instead, 400 is a CD, etc.

- Fourth Rule

This states that if a symbol comes after itself, it is added.

The examples are below

- CCC = 100 + 100 + 100 = 300
- CCLV = 100 + 100 + 50 + 5 = 255
