Methods Of Converting XXVII Roman Numerals To Arabic number

 

In this section, we are going to take a look at some of the ways that can be used to convert XXVII Roman numerals to Arabic numbers. Two methods are generally used in the convention of Roman numerals to Arabic numbers and vice versa, the two methods are elaborated below:

  • 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

XXVII = X + X + V + I + I = 10 + 10 + 5 + 1 + 1= 27.

  • Second Method

This second method involves grouping the Roman numerals for either subtraction or addition.

The illustration is given below

XXVII = XX + VII = 20 + 7 = 27. And you are good to go, isn’t that simple?

XXVII Roman Numerals

From the foregoing, we have seen that XXVII represents 27. But in this section, we are going to look at how to convert Roman numerals of any sort to Arabic number following established procedures.

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

Thousands Hundreds Tens  Ones
Arabic Numerals 2 7
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 7 is under the One’s column. From the table now, we see that the fourth row has Roman numerals of XX while the second row on the one’s column contains VII. Hence when you add the two together i.e XX + VII you will get XXVII which is equal to 27 in Arabic form.

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.

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;

  1. XXVIII = 10 + 5 + 3= 18
  2. 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

  1. IX = 10 – 1 = 9
  2. XXL= 50 – 10 – 10 = 30
  3. 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

  1. XXX = 10 + 10 + 10 = 30, hence 40 is not XXXX instead it is XL.
  1.  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

  1. CCC = 100 + 100 + 100 = 300
  2. CCLV = 100 + 100 + 50 + 5 = 255
