Happy New Year, MMXI: 2011 In Roman Numerals

OK, now that you know that 2011 in Roman Numerals is MMXI, here is some background on the conversion between Roman Numerals and Arabic numerals which is what we currently use as our numbering system.

M=1000 | D=500 | C=100 | L=50 | X=10 | V=5 | I=1
The letters (roman numerals) are arranged from left to right with each letter decreasing in value as you go "down the line." The totals are derived through adding the numerical equivalent of all the letters.

Therefore . . .
MDCLXVI = 1000 + 500 + 100 + 50 + 10 + 5 + 1 = 1666.

The conversion between Roman Numerals and Arabic Numerals is a little bit more complicated than that but you get the idea.

Here is a list of Roman Numerals for the years 2011-2020

2011 = MMXI
2012 = MMXII
2013 = MMXIII
2014 = MMXIV
2015 = MMXV
