1999 = MCMXCIX
1776 = MDCCLXXVI
I suppose you would first convert MCMXCIX to a form that has only added characters...
1999 = MDCCCCLXXXXVIIII
Then to subtract the smaller from the larger, just cancel the common parts from the greater number...
MDCCCCLXXXXVIIII
... leaving CCXXIII (223).
To add them, arrange the elements of both in descending order, then simplify if necessary...
MMDDCCCCCCLLXXXXXXVVIIIII
DD = M, CCCCC = D, LL = C, XXXXX = L, VV = X, and IIIII = V...
MMMDCCLXXV (3775)
No, you can do Sudoku with letters or shapes sometimes. You don't actually have to add or subtract or do math calculations when playing it.
To subtract in Roman numerals, you simply place a smaller number in front of a larger one. You subtract the value of the smaller number from the larger one. For example, to express 4 in Roman numerals, you write IV (5-1). Similarly, to express 9, you write IX (10-1).
For example - 1V = _____ II is 2 1V is 4 so 4 - 2 --------- 2 ---------- so to subtract u must first have the two numbers u add the same way if u add you will get 6
L is 50 and I is one, so LI would be 51. However, if the numerals were IL, then you would have to subtract. Then it would be 49.
Subtract 273.15 (or 273, for approximate calculations), from the number of Kelvin.

Notwithstanding the fact that in todays modern notation of Roman numerals 999 is now considered to be CMXCIX inasmuch that the ancient Romans would have probably subtracted the given numbers in either of the following formats:-As: MDCCLXXVI-IM = DCCLXXVII => 1776-(1000-1) = 777.Or as: MDCCLXXVI-DCCCCLXXXXVIIII = DCCLXXVII => 1776-999 = 777.For more complicated calculations the Romans would have used an abacus calculating device.QED

Yes the educated Romans were able to add and subtract mentally but for more complicated calculations they would use an abacus calculating device.

The idea is to subtract 1 from that number.
It is now generally accepted that the modern way of expressing 1999 into Roman numerals is now MCMXCIX but the ancient Romans would have probably worked out the above as follows:- A: MDCCLXXVI+IMM = MMMDCCLXXV => 1776+(2000-1) = 3775 B: MDCCLXXVI+MDCCCCLXXXXVIIII = MMMDCCLXXV => 1776+1999 = 3775 C: MDCCCCLXXXXVIIII-MDCCLXXVI = CCXXIII => 1999-1776 = 223 The above calculations are fairly easy and straightforward but for more complicated calculations the Romans would have used an abacus counting device.
before we show how to subtract in roman numerals, let's check the answer first. 1999 - 444 = 1555 1999 = MCMXCIX 444 = CDXLIV 1555 = MDLV if we separate them into each digit: 1999 = M/CM/XC/IX 444 = 0/CD/XL/IV (0 is just there as a placeholder so each has 4 "digits") 1555 = M/D/L/V And after this, we realize why people stopped using roman numerals and went with the superior hindu-arabic numerals. It just works.
Yes the ancient Romans were able to add, subtract, divide and multiply They also had their own numeracy system known today as Roman numerals
There are no advantages for Roman numerals for anything other than "looking vaguely cool" (and even that's questionable). In every other way they're far inferior to the normal Arabic numerals.
