• What is the use of learning Roman numbers?
• You can use it for Tally Charts it saves a lot of space on the page too by writing IV for 4 or V for 5 rather than writing in 1 2 3 4 5 6 7 8 9 10 11... etc... which takes up more room. It's like Tally Marks and Archaeologists think Roman Numerals may have started as Tally Marks.
• why are there letters with numbers?
Why is there no zero?
• The number zero does not have its own Roman numeral, but the word nulla (the Latin word meaning "none") was used by medieval scholars. "Zero" was used but as a word, "nulla" meaning "nothing", not as a symbol. When division produced zero as a remainder, "nihil", also meaning "nothing", was used. The initial "N" was used as a zero symbol in a table of Roman numerals by Bede or his colleagues around 725. We usually traslated the meaning of the symbols like ("X" means 10) but they didn´t, they understood "X" as "1,1,1,1,1,1,1,1,1,1". At present we use the Roman numerals for dirrections, organize books, data, historical dates, etc.
• Does ss have any meaning in Roman numerals? Could it possibly represent one-half?
• Is something wrong with the video? It's not loading or playing...
• Why is there not a specific number for zero?
• Roman numerals come from ancient rome but how is 100 c
• The ancient Romans spoke Latin. The Latin for 'hundred' or 'a hundred' is 'centum', which of course begins with 'C'. Which is also the reason why we have 'century' and 'centimetre', and also why the Romans had a type of military leader called the 'centurion'.
