What is the largest number that can be written using Roman numerals without using the bar or subtraction principle?
X = 10X with a bar over it = 10000ex. - XII with a bar over it is 12,000example of subtraction principle IX = 9
Wow. I did not know that about the bar. Then the answer might be:MMMDCCCLXXXVIII = 3888Right or wrong?
Thanks! After I wrote it I had to check the Roman numeral page at Wikipedia to see something, and I saw that the bar is used when numbers go above 4000. Since there is no single numeral above 1000, I didn't know how many Ms could occur in a row. The limit is therefore 3.Now how would you write a number like 12,345?
So the bar would extend only over the first three numerals only….would there be a space between the XII and the CCCXLV? Or would they all be in a single string? This is good stuff to know for my final round on Jeopardy some day. 😉
