Roman Numerals were used in the ancient Romans to represent numbers. The characters consits I,V,X,L,C,D, and M they all represent a number that remined Romans about a certain number.
I represents 1, V represents 5, X represents 10, L represents 50, C represents 100, D represents 500, and M represents 1000. If a smaller digit is put first you subtract that many, for example: IV since 1 is infront of 5 is subtracts 1-5 to make 4. When the bigest digit starts off it adds.
I enjoyed this activity I learnt how to understand the Roman Numeral Method with adding and subtracting.
