The rules as we now know them today now governing the Roman numeral system had absolutely nothing to do with the ancient Romans whatsoever because they were introduced during the Middle Ages and as a result of these rules the equivalent of the given numbers are now considered to be XLIX, XIX, CMXCIX and DCCIX respectively which does not quite lend themselves easily towards the purpose of arithmetical operations but the Romans would have most probably worked the equivalent of 49, 19, 999 and 709 in a logically abridged format as follows:-

IL+IXX+IM+IDCCX = MDCCLXXVI => (50-1)+(20-1)+(1000-1)+(710-1) = 1776

Note that if we were to work out the given numerals in an expanded format or indeed a combination of both abridged and expanded formats then the results would be exactly the same and that for more complicated calculations the Romans would have used an abacus calculating device.

What is a 5 letter word made up entirely of roman numerals?

The five letter word MIMIC can be formed from Roman numerals but as the individual numerals are in the wrong order it isn't a real Roman numeral.


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).


What does CCCXCIV mean in Roman numerals?

In today's modern usage of Roman numerals, CCCXCIV represents 394, but the ancient Romans would have converted and notated the equivalent of 394 into Roman numerals entirely quite differently.

How would you add together 51 plus 49 in two different ways and 51 minus 49 in two different ways but showing all calculations entirely in Roman numerals with explanations?

Doing arithmetic with Roman numerals is exasperating, and imho a pointless waste of time, except to demonstrate the obvious superiority of our "normal numbers," which use base-10 radix / positional notation that includes a zero digit as a placeholder. I'd venture to say science & technology -- commerce, too -- could never have developed in recent centuries if we still used Roman numerals for calculations. However, this web site explains some methods: http://turner.faculty.swau.edu/mathematics/materialslibrary/roman/


When was Roman Numerals changed to numbers?

Bear in mind that Roman numerals actually are numbers, they are just not the kind of numbers that we presently use, which are called Arabic numerals. Arabic numerals were first used in Europe in the year 976 AD. Roman numerals still have not entirely fallen out of use, although for most purposes we use Arabic numerals.
