What are Roman Numerals?

Roman Numerals are what Romans used to use for numbers. Different symbols have different numeral values. For example, I = 1, V = 5, and X = 10. When these symbols are combined in different ways the other numbers are formed. There are several rules for the placement of the symbols.You may place up to 3 of the same symbol adjacent to each other to indicate addition. For example: I = 1; II = 1+1 = 2; III = 1+1+1 = 3. Note that IIII is not proper because you may have no more than 3 of the same symbol in a row.You may place a smaller symbol after a larger one to indicate addition. For example: V = 5; VI = 5+1 = 6; VII = 5+1+1 = 7; VIII = 5+1+1+1 = 8. Again VIIII would not be proper because there are 4 Is immediately adjacent to each other.You may place a smaller symbol immediately before a larger symbol to indicate subtraction. For example IV = 5-1 = 4; IX = 10-1 = 9.The basic numerals are:I = 1V = 5X = 10L = 50C = 100D = 500M = 1000If it has a line over it, it means multiply by 1000, like L, would be 50,000Some examples of correct Roman Numerals:III = 1 + 1 + 1 = 3IX = 10 - 1 = 9XIV = 10 + 5 - 1 = 14XXXII = 10 + 10 + 10 + 1 + 1 = 32LXIX = 50 + 10 + 10 - 1 = 69MMVIII = 1000 + 1000 + 5 + 1 + 1 + 1 = 2008MMIX = 1000 + 1000 + 10 - 1 = 2009Here are some of the roman numerals:1-I5-V10-X20-XX30-XXX40-XL50-L60-LX70-LXX80-LXXX90-XC100-C200-CC300-CCC400-CD500-D600-DC700-DCC800-DCCC900-CM1,000-MThe first few Roman numerals are: I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII and so on.
