The Romans designed the numbers by repeating some symbols before the ancient Egyptians did many years ago.
Their numerical values are as follows; i = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000
These letters, which are occasionally used today, can be brought together to create larger numbers. For example, "25 ″," XXV "is written.
There are some rules that must be observed when writing these numbers:
A letter can be written up to three times each side.
If the letter to the right is smaller than itself, the numbers are summed. Like XI = 11, DCX = 610, lxxvii = 77.
When written to the left side is removed. Like XC = 90, il = 49, CD = 400. Only one letter can be written.
Different numbers can be written by typing letters that have a smaller value both to the right and left. Cmli = 951, XLVII = 47, CDLV = 455.
The largest and longest number to be written with the Roman numeral is "3888 ″. (MMMDCCCLXXXVIII)
Not too often, but when they need larger numbers, they draw a line to increase the value of the letters "1000 ″ times.
The letter values that are on the line are as follows; V = 5000, X = 10000, L = 50000, C = 100000, D = 500000, M = 1000000
Due to the difficulty of doing four transactions today is not much use. Although some procedures are developed, they are inadequate when it comes to large numbers. However, there are some use areas such as bullets, clocks, book pages numbering, etc.
