How would you subtract 12 from 2011 in Roman numerals giving reasons for your answer?

MMXI - XII = MCMXCIX (1999)
The above is officially the correct answer which goes against all mathematical reasoning. There is evidence to suggest that the Romans themselves would have worked it out as:-
MMXI - XII = IMM (-1+2000 = 1999)

To subtract 12 from 2011 in Roman numerals, we can represent 12 as "XII" and 2011 as "MMXI." When subtracting "XII" from "MMXI," we start from the left and compare each corresponding numeral. "M" is greater than "X," so we keep it and move to the next numeral. "M" is also greater than "I," so we subtract "II" from "M" to get "MI." The final answer is "MI" (1001).

How do you subtract in Roman numerals?
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).
What are the advantages and disadvantages of using roman numerals?
Advantages of using Roman numerals: In outlines, you can differentiate between indented subsections, giving more clarity to an outline. It is harder to misinterpret a number if the number is smudged in writing.Disadvantages: There is no "zero" in Roman numerals. They are much harder to add and subtract, especially in numbers greater than ten. The hindu-arabic numbering system is more succinct (for example, the year "1988" in Roman numerals is "MCMLXXXVIII". The largest number that can be expressed properly in Roman numerals is 3,999,999 as MMMCMXCIXCMXCIX (the bolded characters would have a line over them.
Do roman numerals add and subtract?
Yes, Roman numerals can be added and subtracted. To add Roman numerals, simply combine the values of the individual numerals. For example, adding "X" (10) and "V" (5) would result in "XV" (15). To subtract Roman numerals, place a smaller numeral before a larger one and subtract its value. For example, subtracting "I" (1) from "V" (5) would result in "IV" (4).
What are the advantages for the roman numerals in trying to add and subtract?
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.
What number is iv?
IV is the Roman Numeral for the number 4.4When reading Roman numerals I before V means subtract 1 from 5.

In the same way that arithmetic is useful today for many reasons

How would you subtract 1776 from 1999 in Roman numerals giving reasons for your answer?
In today's terms 1999 and 1776 expressed in Roman numerals are MCMXCIX and MDCCLXXVI respectively. To find the difference of these numerals is almost impossible because of the way that 1999 is expressed despite the fact that 1776 is correct. But the Romans would have probably expressed these numbers in the following manner IMM and MDCCLXXVI. IMM is a simplification of MDCCCCLXXXXVIIII So: MDCCCCLXXXXVIIII - MDCCLXXVI = CCXXIII (223) by cancelling out the numerals. Check: MDCCLXXVI + CCXXIII = MDCCCCLXXXXVIIII = IMM when simplified The way we work out Roman numerals today is different in the way that the Romans actually did themselves because the rules governing the Roman numeral system were changed in the Middle Ages. Presumably to make it easier to convert Roman numerals into Hindu-Arabic numerals that were gradually being introduced into Western Europe.

What number is iv?
IV is the Roman Numeral for the number 4.4When reading Roman numerals I before V means subtract 1 from 5.
What number is represented by XL in roman numerals?
40. L is 50. Putting the X behind the L means you subtract the 10 from the 50, and you get 40.
Why were roman numerals invented?
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.
What does LI represent in Roman numerals?
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.
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)
How do you determine 46 in XLVI in roman numerals when the L in roman numerals means 50?
To determine 46 in Roman numerals, you have to subtract 1 (represented by I) from 50 (represented by L) which gives you 49 (XLIX). Then, add 1 (I) to get 50 (L), resulting in XLIX + I = 50 (L). Therefore, 46 in Roman numerals is XLVI.
