The rules now governing the Roman numeral system as we know them today had nothing to do with the Romans because they were introduced during the Middle ages but there exist credible evidence to show that the ancient Romans would have worked out all four calculations in the following formats:-
MDCCLXXVI+SXC = MDCCCLXVS => 1776+(100-10.5) = 1865.5
MDCCLXXVI+LXXXVIIIIS = MDCCCLXVS => 1776+89.5 = 1865.5
MDCCLXXVI-SXC = MDCLXXXVIS => 1776-(100-10.5) = 1686.5
MDCCLXXVI-LXXXVIIIIS = MDCLXXXVIS => 1776-89.5 = 1686.5
Note that in mathematics -(100-10.5) becomes 10.5-100 and that the above calculations were fairly simple and straightforward to work out but for more complicated calculations the Romans would have used an abacus calculating device.

How would you actually add together 1666 and 1999 in two different ways entirely in Roman numerals throughout both calculations with explanations?
See answer to question: ' How do you add together 1666 and 1999 in two different ways using Roman numerals'
What is the sum of 1999 and 2014 added together in two different ways entirely in Roman numerals with explanations?

How would you work out 1776 plus 549 in two different ways and 1776 minus 549 in two different ways but working out all four calculations entirely in Roman numerals with explanations?
Roman numerals are entirely inappropriate for doing such calculations. I believe the people in Roman times did such calculations on an abacus or something similar - which is basically similar to converting them to the Arabic numbers we use. If you really want to do it in Roman numerals - which is basically NOT a good idea - you would have to keep the thousands, hundreds, etc. separate, and handle carry (for addition) and borrowing (for subtraction).
How 100 subtracted by200 in roman numerals?
c - cc = -c
Which are the Roman numerals that are never subtracted?
The fives (V=5, L=50, D=500) are never subtracted in Roman numerals, because, for example, VX for 5 (10-5=5) is the same value as just plain V.
The symbol of roman numerals which can never be subtracted?
It looks like the letter N which is the symbol for nought and nothing can't be subtracted from anything because it remains the same.
What is 1776 plus 444 added in two different ways and 17776 minus 444 subtracted in two different ways but working out all four calculations in Roman numerals?
Both 1776 plus 444 added in two different ways will have sum of MMCCXX = 2220 and both 17,776 minus 444 subtracted in two different ways will have a difference of (XVII)CCCXXXII = 17,332
What is this roman numerals in number for xciv?
94. XC is 10 subtracted from 100, aka 90. and IV is one subtracted from 5 aka 4. 90+4=94
How would you subtract 999 from 1776 in two different ways with all work shown entirely in Roman numerals?
Notwithstanding todays modern conversion of 999 into Roman numerals which are now considered to be CMXCIX inasmuch that the ancient Romans probably would have subtracted the equivalent of 999 from 1776 in either of the following formats:- A: MDCCLXXVI-IM = DCCLXXVII => 1776-(1000-1) = 777 B: MDCCLXXVI-DCCCCLXXXXVIIII = DCCLXXVII => 1776-999 = 777 QED
How would you work out 1776 plus 9 in two different ways and 1776 minus 9 in two different ways but working out all four calculations entirely in Roman numerals with explanations?
When 9 is converted into Roman numerals it is IX which is an abridged version of VIIII and so the required calculations are as follows:-MDCCLXXVI+IX = MDCCLXXXV => 1776+(10-1) = 1785MDCCLXXVI+VIIII = MDCCLXXXV => 1776+9 = 1785MDCCLXXVI-IX = MDCCLXVII => 1776-(10-1) = 1767MDCCLXXVI-VIIII = MDCCLXVII => 1776-9 = 1767Note that in mathematics -(10-1) changes to 1-10QED
What do the roman numerals MCMXXIX equal?
M=1000CM=900D=500C=100X=10I=1When the I is placed before a X then 1 is subtracted from 10 = 9When the I is placed before a V then 1 is subtracted from 5 = 4So 1000 + 900 + 10 + 10 +9 = 1929The original answer was entirely deleted by WikiAnswers contributor Viki101 in whose view the answer should have been as the above. The original answer was as follows:In today's terms the Roman numerals MCMXXIX represent the number 1929.But in the times of the Romans themselves they would almost probably have written out 1929 as MDCCCCXXVIIII.
What does xxxix represent in roman numerals?
The Roman numeral XXXIX represents the number 39. X (10) is subtracted from L (50) in order to express the number 40, and then I (1) is subtracted from 40 to represent 39.
