The counting system of Roman Empire was different from the system of writing the numerals, which we use now days. Ours number system is called the decimal number system as it is made of 10 Numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. All these numbers are used to make big numbers which we use in our daily life. But the same numbers were written in Roman Empire using different symbols. This system is called Roman System of writing the numbers.

To write a roman number, we should know the different symbols used to write the numbers. Some of the common Romans numbers are as follows:
| Numbers | Roman Numerals |
| 1 | I |
| 5 | V |
| 10 | X |
| 50 | L |
| 100 | C |
| 500 | D |
| 1000 | M |
There are some rules to be followed for writing the Roman Numerals:
- Symbols I, X, C and M can be repeated 3 times at a given place and rest symbols can be used only one time.
- For addition and subtraction of the Roman numerals, we can use only the symbols I, X and C. When we place a smaller symbol at the left of the bigger symbol, it indicates subtraction and if we place a smaller symbol on the right, it indicates addition.
- A symbol ‘I’ can be added to any Roman symbol, but it can be subtracted from only two symbols namely ‘V’ and ‘X’.
- 'X’ can be added to all symbols, but can be subtracted from ‘L’ and ‘C’ only.
- ‘C’ can be added to every symbol, but can be subtracted from ‘D’ and ‘M’ only.
