Background of Project Euler Problem 20 C

I use the Big Integer class from the last two videos to solve Adding up all the digits in 100! (factorial, not yelling the number). Videos going forward should be in 1440p 60fps if all goes right. In this video I implement the comparison operators for our Big Int class and use it to solve In this video, I will be coding the solution for the 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! Hey Nerd boys and girls. Wanna learn about Factorials? Yeah, me neither, so we're also gonna look back at
