Roman Symbols are the numerals used in the system of numerical notation. Roman Symbols came from Rome, where people wanted to use their own numerals to write various numbers. Roman Numerals are the collection of symbols C, D, I, L, M, V, X which are written in a specific order. A subtractive notation in Roman Symbols is found by taking the last character value and subtracting the value of the character that comes just before it.

### How to Read Roman Numerals?

C, D, I, L, M, V, X are any symbols of Roman Numerals. ‘I’ can be read as 1, ‘V’ can be read as 5, ‘X’ can be read as 10, ‘C’ can be read as 100, ‘M’ can be read as 1000. If ‘I’ is placed before V then it is 4. If ‘I’ is placed is after ‘V’ then is 6. Similarly, If ‘I’ is placed before ‘X’ then it is read as 9. If ‘I’ is placed after ‘X’ then it is 11. If ‘C’ is placed before ‘X’ then it is read as 90.

### Rules to Express Roman Symbols

1. We can use I and X 3 times in a numeral.
2. We never use V, L, D more than one time. We have to use it only once.
3. When we write a smaller symbol to the left of the greater symbol it means that the smaller numeral is subtracted from the greater one.
4. When we write a smaller symbol to the right of the greater symbol it means that the smaller numeral is added from the greater one.
5. We never write V to the left of X. Similarly, L and D are never written to the left to any other symbol.
