Today we would write out the equivalent of 19, 49, 99 and 999 into Roman numerals as XIX, XLIX, XCIX and CMXCIX respectively and to add them up in this format is an almost impossible task.
However notwithstanding the above the Latin language itself lends credence to the fact that these numerals would have probably been written out as IXX, IL. IC and IM respectively during the Roman era which would make them straightforward to add up in the following manner:-
IXX+IL = LXVIII (19+49 = 68)
LXVIII+IC = CLXVII (68+99 = 167)
CLXVII+IM = MCLXVI (167+999 = 1166)
Roman numerals: M=1000, D=500, C=100, L=50, X=10, v=5 and I=1
Necessity is the mother of all inventions and Roman numerals were needed in the past just for the same reasons that we still need numbers today.
Roman numerals were inspired by Etruscan numerals of which Roman numerals originated from.
For exactly the same reasons why numbers are stillimportant to us today.
MMXIIII as the alternate (on clocks for example) version of number 4 is IIII
113 = CXIII in Roman numerals
In the same way that arithmetic is useful today for many reasons
Necessity is the mother of all inventions and Roman numerals were needed in the past just for the same reasons that we still need numbers today.
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)
