The M comes from the roman sign for 1000.

I = One
V = Five
X = Ten
L = Fifty
C = One hundred
D = Five hundred
M = One thousand

All sings with a - above it had to be multiplied by one thousand.
All lower number in front of a higher number should be subtracted from the higher number so CM is 900, IV is 4, MCM is 1900, etc......

MCMLXXXVII would be 1987

M = 1000
CM = 900
L = 50
XXX = 30
V = 5
II = 2
Add them up and you’ll get 1987. The same goes for MMVII (2007).

So MM would actually be 2000 but as far as I Know it stand for More then M on this board.
