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?

  • 1000 = M

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