How would you tot up 89.5 79.5 19 and 14 in Roman numerals giving step by step instructions and clear reasons for your answer?
Because of gradual changes over the past centuries the way we write out Roman numerals today to represent a quantity is different to the way that the Romans actually did themselves.
But there is evidence to suggest that the Romans would have probably wrote out the above numerals in a simplified form of SXC, SXXC, IXX and IXV because:-
SXC is a simplification of LXXXVIIIIS (-10.5+100 = 89.5)
SXXC is a simplification of LXXVIIIIS (-20.5+100 = 79.5)
IXX is a simplification of XVIIII (-1+20 = 19)
IXV is a simplification of XIIII (-1+15 = 14)
Simplification is obtained by placing equal values to both sides of the numerals but in opposite directions. They then would have probably added them up in the following manner:-
SXC+SXXC = ICLXX (169)
ICLXX+IXX = IIXCC (188)
IIXCC+IXV = CCII (202)
In his reference book about ancient numeracy systems entitled "History of Mathematics" volume 2 by David Eugene Smith first published in 1925 and ISBN 0486 204 308 examples are given that the Romans would sometimes simplify their numeracy system in the above manner. Presumably this was done in order to use less numerals for a given value.
Roman numerals: M=1000, D=500, C=100, L=50, X=10, V=5, I=1 and S=1/2

How do you work out 1776 plus 1999 in Roman numerals giving reasons for your answer?
Today we write out 1999 in Roman numerals as MCMXCIX because of changes made to the rules governing the Roman numeral system during the Middle Ages and to add these numerals to MDCCLXXVI is almost impossible. But the Romans themselves would have calculated 1999 on an abacus counting device as MDCCCCLXXXXVIIII and probably simplified them to IMM by placing I to both sides of the numerals. So: MDCCLXXVI + (-I+MM) = MMMDCCLXXV (3775)
