Factorials Demystified

Time is valuable, so why spend more of it preparing for your exam than absolutely necessary?

Okay, let's dive in.

A Tale of Two Candidates

Consider the following two hypothetical students studying for their respective exams.

Candidate A: Studies for 100 hours.

Candidate B: Studies for 80 hours.

Which student do you think is likely to get a higher score?

It's a trick question. On the surface, it seems like Candidate A is the obvious...
