When it goes over or equal 4000 It shows a line above the roman numeral and you can even put more than one line on top of the roman numeral.

SoulWatcher IL is a legal way to write 49 but it's not the standard way. The standard rule is that to take away from a roman numeral is that the "subtraction numeral" has to be the numeral listed directly BEFORE the numeral that is the "main numeral". (e.g. D is before M, X is before L, C is before D, etc.) (List: I V X L C D M) (Standard Roman Numeral "49": XLIX)

4000 is not MMMM
A number can NOT be repeated more than THREE TIMES in a row

Aurora 2023-05-09 18:28:57

Adding to the rules of subtracting within Roman Numerals:

Roman Numeral Symbols are split up into two groups:

1) Powers of 10:
10^0 = 1 = I
10^1 = 10 = X
10^2 = 100 = C
10^3 = 1000 = M

2) Powers of 10 multiplied by 5:
10^0 *5 = 5 = V
10^1 *5 = 50 = L
10^2 *5 = 500 = D

You CAN subtract symbols of the 1st group from the symbol that has its value multiplied by 5:
IV = 5-1 = 4
XL = 50-10 = 40
CD = 500-100 = 400

You CAN also subtract the symbols from the powers of 10 from the next bigger symbol within that group:
IX = 10-1 = 9
XC = 100-10 = 90
CM = 1000-100 = 900

You CANNOT subtract the symbols of the second group from the symbol that has its value multiplied by 2 as that would be redundand:
VX would be: 10-5 = 5 = V
LC would be: 100-50 = 50 = L
DM would be: 1000-500 = 500 = D

You also CANNOT subtract symbols from the powers of 10 multiplied by 5 from the next symbol within that group:
VL is not: 50-5 = 45, but: XLV = 50-10+5 = 45
LD is not: 500-50 = 450, but: CDL = 500-100+50 = 450

Roman numeral MMXXIII is 2023 in numbers.

Ayomi 2023-04-21 07:17:22

This is really great to my work that i do#]

2023-04-16 11:53:08

for SoulWatcher, and other people who wonder why things like, say, 49 is represented as XLIX, and not simply IL. this is because in standard roman numerals, you can only conduct subtraction with numerals that are behind in value by no more than one numeral.

that is, the following are valid:
IV = 4 (V is directly after I)
IX = 9 (X is one numeral after I; V)
XL = 40 (L is directly after X)
XC = 90 (C is one numeral after X; L)
CD = 400 (D is directly after C)
CM = 900 (M is one numeral after C; D)

and examples of technically invalid representations include:
IL =/= 49 (L is two numerals away from I; V, X)
VM =/= 995 (M is three numerals away from V; X, C, D)
VD =/= 495 (D is two numerals away from V; X, C)

Old movies have the copyright year in the credits expressed as Roman numerals. This was done to fool movie goers into thinking they were watching a new release when the studios were really just giving a new title to a movie that was a few years old.

Why? 2023-03-19 01:02:37

Thank God that unlike the imperial "system," the USA decided to not stay in 9th century Rome and switched to Arabic numerals.

XV is 15 and XXXIV is 39
What does alphabet mean?

Debra 2023-02-25 15:15:20

To vojse

The amount you are taking away goes in front of the letter, not after.
MD does not = 1000 - 500 , but 1000 + 500
DM = 1000 - 500

You do not write 4 of the same letter next to each other.
400 is not written, CCCC but it's 100 less than 500
400 = CD

I hope that helps.

vosje 2023-02-16 15:40:09

@susan frissell when looking further on that same site, i found
M____D_______C___C___C___C__V_I__I__I
(1000-500=500)+100+100+100+100+5+1+1+1=908
so i dont know, this is the same story...
M____D_______C___C___C___C_=CM
(1000-500=500)+100+100+100+100=900

can someone translate this. I think it's roman numerals. I suspect it is a year but not sure:

The chart is missing the line for 1000.

1999 = MCMXCIX.

Wouldn't MIM be simpler?

Maximvs 2023-01-19 08:45:36

To Babette:

In roman numerals, a lower symbol BEFORE a greater indicates a subtraction.
e.g.: IX = 10 (X) - 1 (I) = 9

By the other hand, if a lower symbol is AFTER a greater, it's an addition.
e.g.: VIII = 5 (V) + 3 (III) = 8

And there's a rule: the symbols to be subtracted/added must be read from right to left.

So, XIX = X + IX = 10 (X) + 9 (IX).

Zenith 2023-01-18 16:54:54

To Babette...You can't have the same numeral, repeating in order, MORE than 3 times. Any smaller valued numeral is subtracted from the next numeral that is greater. E.G. IX is 9..(1minus10) You have to recognize the lower valued numeral and put it in a separate bracket with the next greater numeral..... X(IX) 10plus(9)

Babette 2023-01-13 03:57:28

Hello, I'm new here. I was wondering why XIX=19, if X=10 and I=1? The way I understand it is 10+1+10=21

Can someone please tell me what I am missing?

King_Whatchamacallit 2022-11-25 19:43:48

@Ernest XLVII is 47, not 49. 49 would be XLIX

LNP 2022-11-20 10:55:10

For everyone saying 4000 is a V with a line on top, that's Vinculum, not an official form of roman numerals but more of an extension to standard roman numerals, also fun fact: the letter M is the only letter that bypasses the rule of "You cannot place a letter 4 or more times in a row", so standard 4000 would be MMMM

khushboo 2022-11-14 21:25:24

hi everyone my name is khushboo and I am 10 years old
first of all i do agree with abdullah but apparently 4000 in roman numerals is MMMM this is the only number that breaks the rules of roman numerals

What is the significance of the comma's and dots between letters? i.e. M,DCCC.XLV.

We can't repeat (M, X, |, or V) more than 3

Generally speaking very Good to know such Roman Numbers especially as time and infinity we are drawing closer climate change and numbers of all kinds Maths and time combine Eternity! Planets forces of life and Space high far away! BC-AD tIme in the Creators hands.

Ryan 2022-07-30 15:55:48

This is going well, but 99999 is not [M repeated 99 times]CMXCIX, It can just be [X with a dash][C with a dash]M[X with a dash]CMXCIX.
Roman numerals can't be repeated more than 3 times.
Other than that, it deserves a VIII out of X! (8 out of 10)

SoulWatcher 2022-07-28 11:58:16

I can read Roman Numerals but sometimes I get messy with the rules because I don’t know the rules I thought I did but I don’t. Not fully. Such as the number 49. I thought take L = 50 and l = 1
And say lL I don’t know why this is wrong. I can write it this way as well.XLIX. Why is the layer the inky right way? What rule am I missing that I can’t seem to find anywhere? Cheers

Rob 2022-07-23 06:33:47

Seems like 490 should be XD, but the correct conversion here is CDXC. Hmm. And 990 should similarly be XM, but the correct answer here is CMXC. This must violate rules of conservation, no? Why would one use four numerals when one could use two? Please clarify. Thanks.

for 4000 and over we need I V X L C D and M with a dash over it for example 15364 should be X-V-CCCLXIV instead of MMMMMMMMMMMMMMMCCCLXIV
