### Roman Numerals

1a. How was the Roman numerical system developed?
The system is based on the number 10 - so no doubt this ancient counting system was originally based based on a counting method using the fingers. A single stroke of the pen would represent one finger. The Latin word for 100 is centum and for 1000 is mille giving the numerals C and M.
1b.The social or cultural development behind the development system.
The Romans were active in trading and commerce, so from the time of learning to write they needed a way to indicate numbers.
1b i.Who developed the numerical system?
The numbers originated from the Etruscans, but the Romans then changed it to suit their counting system.
1b ii.Why was it developed?What function did it serve?
It was developed as the Romans required a numerical system for their trading and commerce.
Roman numerals traditionally indicate the order of rulers or ships who share the same name (i.e. Queen Elizabeth II). They are also sometimes still used in the publishing industry for copyright dates, and on cornerstones and gravestones when the owner of a building or the family of the deceased wishes to create an impression of classical dignity.
2a. In the Roman number system there is a repetition of symbols.These are the following numbers:
I = 1     V = 5
placing  any smaller value in front of any larger value,  indicates subtraction.That is, the preceding smaller value is subtracted from the following larger value. If ‘I’ is placed behind ‘V’ the it would mean that it is 4. Although IIII can be used, it is used rarely. Placing a smaller value after a larger one indicates that the smaller value is added to the preceding larger value. If ‘I’ is placed in front of ‘V’, is would that it is 6. In Roman number system IIII can be used, so it shows that there is a repetition of symbols in the system.
2b. In the Roman number system ‘X’ which equals to 10 is the base for the system
2c. There wasn’t a symbol of zero in the Roman number system till 1000AD in Europe.
2b. These are the symbolic representations of the various numbers.                                                        I = 1   V = 5   X = 10   L = 50   C = 100   D = 500   M = 1000   V = 5,000 X = 10,000   L = 50,000   C = 100,000   D = 500,000   M = 1,000,000
