Review of the Roman Numeral System

Roman numerals I, V,  Hindu-Arabic number system. After the token value or higher, the value of the first token is increased. A token with a higher  value will be devalued. So evidence first appeared between 900 and 800 BC. 

To express numbers starting with  4 or  9,  one of the larger values ​​is placed in front of a sign that reduces its value – for example, IV = -1 + 5 = 4, XC = -10 + 100 = 90, and CD = -100 + 500 = 400 Normally only three  symbols can be used in a row. The only exceptions are watches, which usually display 4 as IIII, and the number 4000, sometimes written as MMMM. When the tie line is placed over the number, the value becomes 1,000. 

Ancient Roman society used many different ways to represent numbers, and one of the most common ways was to represent the numbers 1 through 10 by hand. The ‘V’ represented five fingers, a V shape consisting mainly of fingers and toes, while the  single line or ‘I’ represented one half or finger. Two crossed arms form an ‘X’. 

Roman numerals of larger sizes derived from other symbols. M = 1,000 – this number was once represented by the Greek letter phi (ф). It was usually pronounced C, I, and C backwards; look at this: CIƆ is similar to M. It is a coincidence that mille is the Latin word meaning thousand. 

Numbers come before and after XXV and XXVIII. How can you read and write these numbers? 

The Roman numeral XXV represents the number 25 and XXVIII represents the number 28. Here are the numbers  before and after XXV and XXVIII and their meanings in  Arabic-Hindu numerology. The following technique can be used to calculate the  value of the numbers 

XXV and XXVIII. 

Method 1: With this method, we divide Roman numerals into individual letters, write the value of each letter, and then add or subtract as needed.  

Historical Examples  

As the Roman Empire collapsed, Christianity (ironically one of Rome’s first attacks on persecution) continued to use its own cultural system. 

Roman numerals are used to designate months in astronomy and periodic table groups in chemistry. Uppercase and lowercase Roman numerals arrange the elements in a convenient order, as shown in the table of contents and manuscript index. Additionally, Roman numerals are used as musical notation. 

In conclusion: Roman numerals are practical but not for good reasons. Roman numerals seem to have a timeless, historical aura that is especially evident on  watches.
