Answer 2

Step-by-step explanation:

Well, the year 1666 uses the Roman numerals in the order MDCLXVI, which is in descending order:

M=1000

D=500

C=100

L=50

X=10

V=5

I=1

Therefore, MDCLXVI is M + D + C + L + X + V + I = 1000 + 500 + 100 + 50 + 10 + 5 + 1 = 1666.

Strangely, this year consists of the number 666, deemed to be unlucky (which itself consists of the first 6 Roman numerals in descending order), and also was the year the Great Fire of London began, which burned London to the ground and cost thousands of people their properties
