Roman Numeral Challenge - geodave - 23-Apr-2012 The whole IX=9 stuff was added in the 19th century -- prior to that you never put them in reverse order at all. I thought that movie copyrights typically said "MCMLXXXIV" for 1984. Maybe I'm remembering incorrectly. Anyway: MMMDCCCLXXVI Roman Numeral Challenge - IceyLava108 - 23-Apr-2012 Quote:The whole IX=9 stuff was added in the 19th century -- prior to that you never put them in reverse order at all. 3,876 Roman Numeral Challenge - Hornlitz - 24-Apr-2012 MDCLXVI (this is actually the lowest number you can have that includes all the letters ) Roman Numeral Challenge - Lessinath - 24-Apr-2012 Dave is right. Originally they were not put in reverse order at all. MMMDCCCCLXXXVIII Roman Numeral Challenge - BitBuster - 24-Apr-2012 Ok, I'm confused...IceyLava seemed to imply that you COULD say IX, XL, etc...just not with the thousands. But then Dave said that the whole "small before large" thing was a 19th century thing...so which is it? Roman Numeral Challenge - geodave - 24-Apr-2012 I'm right, of course! Prior to about 1850, you always put them in the "bigger to smaller" order: MDCLXVI Then, somebody decided that it would be okay to "shortcut" the system by allowing letters that stood for "1"s in any place to be put to the left of the next two highest numbers, to denote "4" or "9". So, C, X, and I can do this: IV = 4 IX = 9 XL = 40 XC = 90 CD = 400 CM = 900 Now, granted, I've never seen anyone use CD, but I am SURE I've seen MCM to mean 1900 in a year. Also, you'll notice that on many clocks they use IX but they don't use IV. They use IIII instead. This might just be aesthetic, or it might be that the "4" thing came later than the "9" thing. [i also noticed that clocks have 4 numbers with just Is, 4 numbers with Vs and 4 numbers with Xs.] Roman Numeral Challenge - BitBuster - 24-Apr-2012 I would never trust a clock that had four I's. Just saying. Roman Numeral Challenge - Green Kitten - 24-Apr-2012 MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMI Kind of a pointless topic, huh?

Quote:Dave is right. Originally they were not put in reverse order at all. This isn't valid either, as you have four C's in a row. However, I will change it to MMMDCCCLXXXVIII... 3,888 Roman Numeral Challenge - BitBuster - 24-Apr-2012 Quote:Not a valid numeral: you cannot have more than three of the same numeral in a row. Then how do you express the number 4, if you can't have four in a row and you can't do the lower-before-higher trick? ::Scratches head:: |
