What is 9001 in roman numerals?

Answer 1

In Roman numerals, M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, and I = 1. A single Roman numeral of lesser value placed before a Roman numeral of higher value means to subtract the lesser one, so CM = 900, CD = 400, XC = 90, XL = 40, IX = 9, and IV = 4, but the lesser number should be no more than one power of 10 less, meaning you do not write IC to mean 99. Drawing a line over a number means to multiply it by 1000, so -V- with a line over it means 5000.

So, 9000 would be M-X- with a line over the -X- to indicate that 10 is multiplied by 1000, so -X- with a line over it is 10,000 and the M preceding it means to subtract 1000. Then, add on the I for 1 to make 9001 = M-X-I
