8 in Roman Numerals

Roman Numerals are symbols representing fixed integer values.The Ancient Romans developed them when counting on fingers became impractical for numbers greater than 10. This led to the necessity to develop a standardized system for trading and communication.

The Roman Numeral system was a popular number system in Europe during the late Middle Ages, which was invented by the Romans to make counting at distances easier as well as beyond ten.

This system is made up of 7 symbols which are: I, V, X, L, C, D, and M, that is 1, 5, 10, 50, 100, 500 and 1000 respectively, to change the position of letters are among the things that you can convert a natural number into a Roman Number.   

The students have to remember the principles of reading and writing Roman numbers for the purpose of not getting them wrong. Here are the basic rules of Roman Numeral writing.

Rule 1: Addition Method - In an addition method, when a smaller number or a same number is placed after the larger number, we will simply add the values, i.e., V (5) + I (3) = VIII (8)

Rule 2: Repetition Method - In a repetition method, the Roman Numerals can be used only three times to get a bigger value. For example: I + I + I = III (3) 

Rule 3: Subtraction Method - In a subtraction method, the smaller number or a same number is placed before the larger number, then subtract the smaller number from the larger one. For example, IV = V (5) - I (1) = IV (4)

Rule 4: Limitation Rule - In a limitation rule, we can’t repeat a symbol more than 3 times. For example: we cannot write the 9 as VIIII, instead we need to write IX (by using subtraction method X (10) - I (1) to get IX (9)).

The 8 in Roman Numerals can be written simply by using symbols, it can be done by two methods listed below.

• by Expansion Method.
• by Grouping Method.

The expansion method is breaking down the numbers based on their place values like thousands, a hundred, tens, and ones respectively. For a better understanding, follow the steps given below.

Step 1: Break down the numbers into place values such as hundreds and tens.

Step 2: Change the place values of numbers into Roman Numerals.

Step 3: Combine the Roman Numerals to get the desired correct value.

For example: VIII

V = 5 

III = 1 + 1 + 1 = 3

5 + 3 = 8

VIII in Roman Numerals is equal to 8 in standard Numerical form.

The grouping method is the breakdown of large Numerals into small parts based on their Roman Numeral values. This method works as follows:

Step 1: Firstly, we look for Roman Numerals that should be added or subtracted.

Step 2: Breaking down the larger numbers into smaller ones.

Step 3: Then add or subtract values of the get desired Roman Numeral

For example: VIII

V (5) and I (3)

We simply add the values here, i.e., V (5) + I (1) + I (1) + I (1) = 8

The grouping method focuses on how smaller numbers are grouped together to get the larger number.

Roman Numerals may seem different from the numbers, but they both are similar. For example, the Roman Numerals of VIII is equivalent to the number 8. Below listed are the Roman Numerals which are related to VIII.

• I = 1
• II = 2
• III = 3
• IV = 4
• V = 5
• VI = 6
• VII = 7
• VIII = 8
• IX = 9
• X = 10

• Additional rule: According to this rule, when the Numerals are combined, their values are summed together. For example, VIII = V + III

• Subtraction rule: In Roman Numerals, the smaller number is placed in front of the larger one it means we should subtract the smaller number from the larger number. For example, XL (40) the X is placed before L (X = 10, L = 50), here we need to subtract from the larger number L (50) - X (10) = XL (40)

• Grouping method: Grouping method is a way of putting smaller numbers together to form a bigger number. For example, thinking of 13 as an X and III, i.e., XIII

• Limitation rule: A rule that specifies that the Numerals such as I, X, and C can only be repeated up to three times.
