what years = MM and MCMXCVLL?

Answer 1

MM = 2000

"MCMXCVLL" is not in a proper format. Those "L"s are probably really "I"s.
MCMXCVII = 1997

Roman numerals break down this way:
M, mille = 1000
D, quingenti = 500
C, centum = 100
L, quinquaginta = 50
X, decem = 10
V, quinque = 5
I, unum = 1

The numbers are written left to write and added together. If a lower number appears before a higher number, those letters together represent the difference between those two numbers.

So, when we look at MCMXCVII, we see:
M = 1000
CM = 100 less than 1000 = 900
XC = 10 less than 100 = 90
V = 5
I = 1
I = 1

Just add those numbers together to get the total
1000 + 900 + 90 + 5 + 1 + 1 = 1997. Simple!

Answer 2

MM- 2000

MCMXCVLL is supposed to be MCMXCVII- 1997

Has something happened in your life in Between 1997 and 2000?

Answer 3

M=1000, C=100, X=10, V=5, L(I think you mean I) =1

a small number before a bigger one means take it away

so

MM =2000

MCMXCVLL = 1000 + (-100+1000)+ (-10+100) + 5 + 1 + 1
=1997

Answer 4

Those are Roman numerals. M represents 1000, so MM is 2000. The second number is broken down as follows:
M = 1000
CM = 900
XC = 90
VII = 7
Therefore: 1997.
I assume you found these at the end of movie credits, where the publish date of the movie is usually shown as Roman numerals.

Answer 5

2000 and 1997

Answer 6

2000 and 1997

Answer 7

2000
and 1997 if L is meant to be I

otherwise L is 50
so 2085! 1990 + 45 +50

Answer 8

I know MM= 2000
but the other no idea

Answer 9

MM = 2000
The other is not valid Roman Numerals, since L is never used in pairs. Also V never precedes L.
The valid part -- MCMXC stands for 1990.
If this is MCMXCVII it stands for 1997.

Answer 10

MM= 2000
MCMXCVLL= 1997
