Help appreciated .. The world of Krypton (1987) #3

Please help me understand this better.

Nyra commits the greatest crime imaginable in what year? How is this pronounced ?

100,892 is my guess. In the Fifth Age of course.

How did you get that number?

Ten to the fifth power is 100,000. Then I added the 892 part. Mix 'em together and that equals 100,892.
