IC

C is 100 and I is 1

-> I before C = 99

The above answer provided by a WikiAnswers contributor is 100% correct. In fact the Latin (the language spoken by the Romans) word for 99 is undecentum which literally means one from a hundred. For example: Multiplying 11 by 9 in Roman numerals: XI times IX = -I(X+I)+X(X+I) Multiplying out the brackets = -X-I+C+X When simplified = -I+C = IC

To write 99 in Roman numerals, you would use the letters XC. XC is short for 100 (C) minus 10 (X), giving a value of 90, and then add the letter IX (9) to get a total value of 99.
