I agree with abdulla
You can only fit the roman numeral 3 times.

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

DCCCCL is not a valid Roman numeral

An error on posting Anonymous - 2022-05-11 02:19:34:
The posting listed "...VI=4, V=5, VI=6..."
Seems to be merely a typo. We know IV=4.
Speaking of the number four: my Latin professor said "IIII" was in common usage, just as was the language we refer to as Vulgar Latin ("vulgar," meaning "of the common people" as opposed to Classical Latin, used by scholarly, educated, elite citizenry).
Fikri 2022-05-28 00:48:16
The Roman numeral ll is not a valid representation for number one hundred (the correct Roman numeral is C)
Anonymous 2022-05-11 02:26:17
Here are some more tips and tricks.
If the bigger number comes first you add. For example VI is 6 because 5 + 1 = 6
But if the lower number comes first you subtract. But you subtract the bigger number to the smaller number. For example IV is four because 5 - 1 = 4. You don't do 1 - 5 = -4
The same rule applies to bigger numbers like 40 and 90. 40 would be XL not XXXX because 50 - 10 = 40 and XC is 90 and not LXXXX because 100 - 10 = 90
Anonymous 2022-05-11 02:19:34
This might help you.
I = 1 II = 2 III = 3 VI = 4 V = 5 VI = 6 VII = 7 VIII = 8
IX = 9 X = 10
L = 50 C = 100 D = 500 M = 1000
The line above the number means to multiply by 1000 so V with a line above it would be 5,000 and M with a line above it would be 1000000

For those asking about IIII for 4 rather than IV, the only place you will (or should) see IIII is on a clock. Early clock makes thought using IV made the clock face look unbalanced. The 4 & 8 are both 2 places from the bottom. The 8, written as VIII, and IV looked unbalanced (due to the angle of the numbers and their width). So they wrote the 4 as IIII.

How do I write 500 million in Roman numerals? I tried online sites but they proclaim its invalid! They only go up to 3,999,999. I thought it would be D(M), with (M) being 1 million.
name 2022-04-16 13:23:54
Number 4 is written as a numeral as: IV and not IIII (though the IIII form circulated as an additive form);
Number 5 is written as a numeral as: V and not IIIII;
Number 10 will be written as: X and not VV, nor VIIIII;
Number 100 will be written as: C and not LL, nor LXXXXX, nor XXXXXXXXXX.
