What are Roman Numerals?

For easier understanding, the following is a table that shows the particular numbers and their Latin symbols in Roman Numerals-

Methods of Calculating Roman Numerals
Following are some of the ways to calculate roman numerals-
Method I-
In this method, the alphabets are first arranged, and their numerical values are placed and then added accordingly.
XXXVII= X+X+X+V+I+I= 10+10+10+5+1+1=37
This is the basic rule for calculating Roman Numerals.
Method II-
This is the grouping method of calculating the value of the Roman Numerals.
For example:
XXXVII= (XXX)+ (VII)= 30+7= 37,
Or,
XXXVII= (XXX)+(V)+(II)= 30+5+2= 37
These are two ways of calculating the value. Once the students get a hang of calculating the values, they can easily find a method they feel more comfortable in and can calculate the values.
Rules to write Roman Numerals
A set of seven symbols make up the roman numerals.
Following are the rules to follow while writing roman numerals.
Rule I-
When a greater symbol is followed by a smaller symbol, the smaller symbol is added.
For example-
MV, where M>V, therefore, MV= M+V= 1000+5= 1005
Rule II-
When a letter repeats itself, the values are added.
For example-
XX=X+X= 10+10=20
Rule III-
When a bigger letter comes after a smaller letter, the smaller letter’s value is subtracted from the bigger letter’s value.
For example-
DM= 1000-500= 500
Rule IV-
The same letter cannot be used more than three times in succession.
For example-
XXX= 10+10+10= 30, but 40 is not XXXX, rather 40=XL (XL= 50-10=40)
