2. Roman Numerals The history of Roman numerals and Roman mathematics isn't well documented. As humans likely began counting by using the simplest things available, the fingers, mathematics developed in a base unit of 10. Actively involved in trade and the use of monetary units, the Romans required a system where counting was more than fingers. The development of the numeric symbols may have been closely related, originally, to the shape of the hand: I for a single finger, V for the whole hand outstretched, X for both hands in the same manner.

3. Roman Numeral : I ; Unus, -a, -um = One This came from the Romans symbolizing the letter ‘ I ‘ for one finger.

4. Roman Numeral : II ; Duo, -ae, -o = Two

5. Roman Numeral : III ; Tres, Tres, Tria = Three

6. Roman Numeral 4 : Quattuor = Four The reason why four is not symbolized as IIII if the letter in front of it expresses greater amount you subtract the 2. This also represented the Roman God Jupiter.

7. Roman Numeral : Quinque = Five The symbol for 5 which is a V came from the romans. It’s meant to symbolize all 5 fingers.

8. Roman Numeral : VI Sex = Six Since the number is above 5, you have to use the V to symbolize 5 and then add additional numerals to equal the number your expressing.

9. Roman Numeral : Septem = Seven

10. Roman Numeral : Octo = Eight Octo now is expressed usually in shapes with anything that has 8 sides but to the Romans it had no meaning.

11. Roan Numeral : IX ; Novem = Nine All the digits that are the factor of 5 will always have the same rules.

12. Roman Numeral : X ; Decem = Ten The symbolize to the Romans was meant to symbolize both hands.

13. Roman Numeral : L ; Quinquaginta = fifty

14. Roman Numeral : C ; Centum = a hundred The symbol ‘ C ‘ is a short way to abreivate Centum.

15. Roman Numeral : D ; Quingenti, -ae, -a ; Five hundred

16. Roman Numeral : M ; Millie = a thousand

17. Roman Numeral : Zero Zero did not have a Roman numeral because the Romans felt it was not important. Zero was expressed by saying “Nulla” which means None.
