How would you convert the Hindu-Arabic numerals of 9 90 1000 900 and 11 into Roman numerals and then add them up?

The above numbers converted into Roman numerals are IX, XC, M, CM and XI respectively and the Romans would have probably added them up in the following fashion: IX+XC = IC IC+M = IMC IMC+CM = IMM IMM+XI = MMX ndu-Arabic conversion: 9+90 = 99 99+1000 = 1099 1099+900 = 1999 1999+11 = 2010 For more complicated calculations the Romans would have used an abacus counting device.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
