Roman Numeration System
By:Courtney Reid
Timeline
The Roman numeration System became the common way to do math in 500 BCE. The usage of the Roman numeration system decreased when other numeration system techniques evolved in the 14th century. It was base 10 but it didn't not include zero so it was inefficient for math purposes.The letters they used to symbolize the numbers where based off of the alphabet that the Romans used.

Calculations
To add Roman Numerals you write the letters out in order from largest roman numeral to the smallest roman numeral. For an example DCCLX would 500+100+100+50+10=760.
-To add two Roman numbers together you have to substitute subtractive (ex. IV would become IIII)
-Then you get rid of the addition symbol and put them together.(ex. DDCX+VIIII would become DDCXVIIII)
-Sort symbols from largest to smallest
-Group the symbols that are the same to make an even larger one. (ex.DDCXVIIII would become MCXVIIII)
-The next step would be to substitute the subtractive.
