Information about Roman Numerals
Roman numerals were a system used to count in the ancient times created by the Etruscan in 525 C.E. and were still continued to be used after the fall of Rome. Some of the roman numeral symbols are I=1, ll=2, V=5, X=10, L=50, C=100, D=500, and M=1000. They were used by the ancient Etruscan as a way to count the money they earned when they traded with other countries or allies. There was no roman numeral for 0. In roman numerals you can not put more than three of the same symbol next to one another. An example would be that you could not write llll= 4. Instead you would have to subtract through the symbols. In order to subtract you would have to put the symbol of lesser value in front of the symbol with greater value. lV=4. If V=5 and l=1. Five minus one would equal four! Amazing right?! The same thing also goes for any other symbols. The only rule to subtracting is you can not put more than one symbol to subtract. An example would be that you could not put llV=3, or you could not put XXL= 30. You would put lll=3 and XXX=30.
