You're literally one click away from a better setup — grab it now! As an Amazon Associate I earn ... I use the Big Integer class from the last two videos to solve n! means n x (n-1) x ... x 3 x 2 x 1. For example, 10! = 10 x 9 x ... x 3 x 2 x 1 = 3628800, and the sum of the digits in the number 10! Adding up all the digits in 100! (factorial, not yelling the number). Videos going forward should be in 1440p 60fps if all goes right. Watch an experienced software developer (Florin Pop) work through the Factorial Digit Sum. Please ! Leave comments and questions in the comment section below.
