#### Symbols of Roman Numbers.

There are 7 Roman Numeral symbols. These are shown in the table below.

For example,They wrote V instead of 5, X instead of 10, and C instead of 100 and so on.

#### What are the rules of Roman Numbers?

Remember Romans Numbers have No Zero. You can go ahead without zero. As you see above there are 7 Roman symbols. We combine these symbols to make new numbers. e.g. 2 can be written in Roman Numbers by combining I and I i.e. 2 in Roman Numbers is II. Similarly, 4 can be made by Combining V and I i.e IV. etc.

Now Lets Learn the basic and easy rule of making Roman Numerals.

When a symbol appears after a larger (or equal) symbol it is added

• Example: VII = V + II = 5 + 2 = 7
• Example: LXXX = L + X + X+X = 50 + 10 + 10 +10= 80.

When symbol appears before a larger symbol it is subtracted

• Example: IX= X − I = 10 − 1 = 9
• Example: 10 = XX − I = 20 − 1 = 19

Remember don`t use the same number more than 3 times like IIII can not be used to make 4.This rule is used to make large roman numerals.

#### How to convert Roman Numerals?

If you want to convert decimal number to any roman numerals break the number into Thousands, Hundreds, Tens and Ones, and write down each in turn. Example

##### Example: Convert 1975 to Roman Numbers.

Break 1975 into 1000, 900, 70 and 5, then do each conversion

• 1000 = M
• 900 = CM
• 70 = LXX
• 5 = V

1000 + 900 + 70 + 5 = 1975, so 19754 = MCMLXXV
