The Romans Numerals


We usually see this number in appendix or at the introduction of many books. Sometimes we got confuse about what this word represent. So, lets execute this confuse.

History of Roman Numerals
Roman numerals, as the name suggests, originated in ancient Rome. No one is sure when roman numerals were first used, but they far predate the middle ages. Theories abound as to the origins of this counting system, but it is commonly believed to have started with the ancient Etruscans. The symbol for one in the roman numeral system probably represented a single tally mark of the kind people would notch into wood or dirt to keep track of items or events they were counting.


How to Translate Roman Numerals
If smaller numbers follow larger numbers, the numbers are added. If a smaller number precedes a larger number, the smaller number is subtracted from the larger. For example, if you want to say 1,100 in Roman Numerals, you would say M for 1000 and then put a C after it for 100; in other words 1,100=MC in Roman Numerals.

Some more examples:
    .:: VIII = 5+3 = 8
    .:: IX = 10-1 = 9
    .:: XL = 50-10 = 40
    .:: XC = 100-10 = 90
    .:: MCMLXXXIV = 1000+(1000-100)+50+30+(5-1) = 1984
