In mathematics, Roman numerals constitute a numbering system where numbers are indicated by specific sequences of letters. The predominant Roman numerals for the numbers one through ten are I, II, III, IV, V, VI, VII, VIII, IX, and X. Within this system, IV denotes the numeral four, signifying “one less than five,” and IX indicates the numeral nine, which translates to “one less than ten.”

Roman numerals Utilize the decimal or base ten systems instead of place value notation. A mix of symbols will represent the Arabic numeral. Roman numerals, which originate from the English alphabet, are not employed universally. English In contemporary Roman numeral notation, seven letters are utilized to signify different numeral values: I, V, X, L, C, D, and M correspond to 1, 5, 10, 50, 100, 500, and 1000, respectively. The English language is composed using a collection of 26 distinct letters known as the English alphabet.

We’ll explore XXV and XXVIII in Roman Numerals” thoroughly, including their meaning, how to convert them, and various illustrations.

**XXV Roman Numerals**

By merging the altered Roman numerals, the Roman numerals XXV can be expressed numerically. The accurate conversion of XXV Roman Numerals is achieved when the larger Roman numerals precede the smaller ones. Now, let’s examine the proper way to translate XXV Roman numerals into their equivalent numeric value.

**How to Write XXV Roman Numerals?**

Either of the two approaches presented below is suitable for determining the numerical equivalent of the Roman numerals XXV.

Approach 1: Split the Roman numerals into individual characters, note down the numerical equivalent for each character, and proceed to perform addition or subtraction with these values.

XXV equates to the sum of two Xs and a V, which respectively represent the numbers 10 and 5, thus yielding a total of 25.

Approach Two: Within this approach, we focus on incorporating both addition and subtraction of sets of Roman numerals.

XXV = XX + V = 20 + 5 = 25

Consequently, the Roman numeral XXV corresponds to the number 25.

**XXVIII Roman Numerals**

The numeral XXVIII in Roman numerals can be converted to numbers by combining the values represented by each Roman numeral letter, that is,

XXVIII

⇒ X + X + V + I + I + I

Add together 10, then another 10, followed by 5, and finally three more, each valued at 1.

⇒ 28.

The translation The placement of the Roman numerals in XXVIII is accurate because the greater-value numerals precede those of lesser value. Now, let’s understand how to properly translate XXVIII from Roman numerals into its corresponding number.

**How Do I Convert XXVIII Roman Numerals to their Numerical Value?**

To determine the numerical equivalent of the Roman numerals XXVIII, refer to either of the two suggested techniques outlined below.

Approach 1 involves breaking down the Roman numerals into individual characters, assigning the corresponding numerical value to each character, and then performing addition or subtraction operations as required.

XXVIII

⇒ X + X + V + I + I + I

Adding together 10, another 10, 5, and then 1 three times.

⇒28

Approach Two: This technique involves utilizing clusters of Roman numerals to perform operations like addition or subtraction.

XXVIII

⇒(XX) + (VIII)

⇒20 + 8

⇒28

Hence, when converted, the Roman numerals XXVIII are equivalent to the number 28.

**Basic Rules to Write Roman Numerals**

Students To prevent errors, it is essential to become proficient in the guidelines for composing Roman numerals. The four basic principles for inscribing Roman numerals are outlined below:

- The characters I, X, and C are allowed to appear three times consecutively. However, repetition of the letters L, V, and D is not permitted; doing so would render the number incorrect.
- When a digit of lesser value is placed to the left of a digit with greater value, it is deducted.
- A lower-valued digit, when placed to the right of a digit with a higher value, results in the addition of its value.
- Only the Roman numerals I, X, and C have the capability to be used in a subtractive manner.

**Roman Numerals to Numbers: Conversion Rules**

Here are the guidelines for conversion: roman numerals to numbers.

- Placing a bar above a numeral signifies that its value should be increased by a factor of 1000.
- When a letter representing a smaller value is positioned before a larger value, the lesser number should be subtracted from the larger one.
- When a higher-valued letter is placed to the left of a lower-valued number, the sum of both values is obtained.
