The Romans and others used the abacus to do their calculations. The Arabic system as demonstrated by the famous Fibonacci was clearly superior for doing calculations. The modern number system ultimately came from the itinerant artisans who traveled from the region of modern Lebanon and Israel to Egypt, to on their monuments. There is a sort of Rune stone figurine that has Egyptian hieroglyphs written on one side and a phonetic letters of a simplified Egyptian letters that represented the same message, but as an alphabet in their native language. That alphabet is the source of all modern alphabets *and* our numbers.
The Indian mathematicians created the zero to clean up the number system and over time the Arabic empire acquired both the numbers and alphabet. The did work to advance complex math like Al Gebra (the way), added to the knowledge accumulated from the Greeks and others as an amassed body of knowledge.
Eventually the knowledge came to Europe through the Spanish after they pushed Muslim rule out of Spain and began to seriously translate the Arabic into Latin where it was shared across Europe.
The rest is history after Bacon established the concept of the repeatable experiment in England. That allowed knowledge to expand based on a growing body of technology shared between members of a growing community who were in pursuit of understanding.
Thus, Roman numeral use fell to headers and the date at the end of a movie.

hey me again! todays comment-

Charles Boylan2020-12-29 15:00:40
The letter M with a dash above it represents 1 million, eg 1000 x 1000, the dash means x by 1000, just as L with a dash above it means 50,000. and D with a dash above it means 500,000.

i like the facts, and this is completely correct, but you forgt to mention when there are 2 dashes or more, in this situation, with __L = 50,000,000

Is there a site that instructs on how to do math in roman numerals? I mean like adding a column, subtracting, dividing or doing other forms of math? Is this really all the romans were able to do "write down a number". Seems just a little lame for math. BTW I can convert the numerals to Arabic numbers do the math and convert answer back to roman however I find nothing in the literature indicating they did this or had even gotten to Arabic numbers until after their empire fell.

Hi,very useful site. Easy to convert numbers to roman numerals and roman numerals to numbers. Can do my calculations very fast. Thank you for creating such a helpful and useful site.

An interesting website, though it has a very conventional approach to Roman Numerals -- the Romans themselves were not quite as strict, nor were many who used them afterwards. I put in MDCCCCIL and it didn't know it, though it was used by a book from an old style publisher. The four "C"s in a row threw the program because that is not conventional, but was done sometimes, and putting an "I" for one before and "L" for fifty would not usually be how one does "49" since it would normally be more the complex XLIX. The rules are not hard and fast, but more conventional versus a little more unusual -- this one uses them as if they were hard and fast. Works though, for that purpose.

totallly in love with this website!!!!
helped me a lot.

which means,there's no Roman numeral conversation in millions, I tried I couldn't get

Well apparently there is a conversion for millions, it just isn't on here. The conversion is _M

zubairuabdullahi 2020-12-03 23:35:03

hiiii 2020-12-03 18:38:55

To Thad, no, it is not a roman numeral. To Didi, MM is 2000. To Dan, there is no zero because nobody has been able to find out what stands for it. Whatever it is, it is not scientifically proven yet.

hiiii 2020-12-03 18:36:13

To Mrs. N, VIIX is not a roman numeral. Bigger numbers have to come first unless the first number is 4 or 9. Same goes for you Kbe, IIIVXX is not a roman numeral. i will do 2 more people. To ADRIEL, mdcccxlviii is equal to 1,848. Finally to This is a really good tool, you are right, but 32787 is _X_X_XMMDCCLXXXVII.

hiiii 2020-12-03 18:29:13

Hi again. I'm answering comments for you! To Sonu, XXV is 25, and XII is 12. Hope this was helpful

hiiii 2020-12-02 18:34:21

This was so fun. For some people though, it is difficult because there is nothing after M. There actually is though. for thousands (and 1M) you have one line over the letters, or one line beside. For example, 5K = _V. It is the same for millions and so on, you just add one line each time you get to M

sven 2020-10-29 21:01:03

this is an amazing app it is so easy and quick to use :)

This website is very helpful

Gremible 2020-07-21 03:09:44

I think we can see why the Roman Empire fell, or at least why there was no significant advancement in mathematics until the Spanish drove out the Moores and discovered Arabic numerals. Try doing division in Roman numerals.

Dhaneswar sing 2020-07-17 05:01:40

What is 7400000008137 in roman numeral? Please tell me quickly,

Trumpisfake 2020-07-14 21:04:58

Sonu 2020-06-09 18:50:44

Someone tattood on his arm XXV♄XII can anyone tell Me what this means?

suresh 2020-06-06 15:15:24

In Roman numerals, x can be used at the most how many times?

This is really a good tool. 2020-05-26 04:22:32

It is good but
32767 must be XXXMMDCCXVII(The three X's in front is "upperlined"),
but it says it is MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMDCCXVII.
You must implement something for bigger numbers.

WOOPWOOP 2020-05-20 17:54:47

I like using this website for my homework idk if its cheating!!

master64c7 2020-05-05 14:35:16

Why do people learning math need to learn this? This isn' t any cool formula or equation, its just how to say numbers in a more difficult way. :(

Eve 2020-03-24 18:42:59

It's useful for people who don't know roman numerals

Its gman on YouTubes little anoying brother >: ) 2020-03-23 18:55:59
