I got that because that is how factorial is defined!
But that's the same as saying - Hence why we got cancellation towards the end of the problem.
your probably gonna get angry if i told you i didnt understand that so im gonna go youtube factorials and ill get back to this problem. thank you for trying to explain. your help was greatly appreciated.
