What does the Roman Numeral IX mean?
The roman numeral IX or ix represents the number 9. Which is so true, it represents the number 9. Roman numerals are; I = one[1], V = five[5], X = ten[10], L = fifty[50], C = one hundred[100], etc. These are the symbols the Romans used. Which is the bases of there numbering system. In order for them to write numbers down as we do (1,2,3,4,5,6,7, etc) when all you have to use is 1,5,10,50,100, etc., is to use mathematics. Strange??? You might say. Very logical though. Okay, so when they want to represent numbers between the numbers they use; 1,5 10,50, etc. they add and subtract. With me so far??? K. It takes knowing ten symbols (0,1,2,3,4,5,6,7,8,9) for us to communicate numbers 1 thru 10. The Romans only need three and must know how to add & subtract. the use of those three symbols & placement of those symbols with each other. Before a basic number is subtracting and placement after a basic number is add. here are some examples; IV = 4 VI = 6 XL = 40 LX = 60 XXXVIII = 38 CLXII = 162
