To add Roman numerals, follow these steps: Convert each number to its Roman numeral equivalent. 1000 = M, 900 = CM, 90 = XC, 12 = XII, 9 = IX. Add the Roman numerals together: M + CM + XC + XII + IX = (1000 + 900 + 90 + 12 + 9) = 2011. So, the sum of 1000, 900, 90, 12, and 9 in Roman numerals is MMXI.
C stands for 100 and X stands for 10. In this case the number would be 90.
90 is written as XC
