• 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.
