Worksheet on Roman Numerals

Practice the worksheet on roman numerals or numbers. This sheet will encourage the students to practice about the symbols for roman numerals and their values.

Rules for Writing Roman Numerals

Rule I: When a symbol is repeated it means the value of each symbol is added. The sum is equal to the number formed.

For example: III = 1 + 1 + 1 = 3,

                     XX = 10 + 10 = 20

                   XXX = 10 + 10 + 10 = 30

Note: V, L, and D cannot be repeated 

Rule II: When a symbol with a smaller value is written before a symbol having a greater value, it means the value of the first symbol is subtracted from the value of the second symbol.

For example: IV = 5 - 1 = 4

                      IX = 10 - 1 = 9

Rule III: When a symbol with a smaller value is written after a symbol having a greater value, it means the value of the first symbol is added to the value of the second symbol.

For example: XI = 10 + 1 = 11

                      VI = 5 + 1 = 6

                   XIII = 10 + 1 + 1 + 1 = 13

Rule IV: For expressing numbers greater than 10, the numbers are first split in terms of tens and ones.

For example:

12 = 10 + 2 = XII

18 = 10 + 5 + 3 = XVIII

29 = 10 + 10 + 9 = XXIX

35 = 10 + 10 + 10 + 5 = XXXV
