Simplifying a factorial divided by another factorial

The video tutorial explains how to simplify the calculation of 25 factorial divided by 23 factorial without using a calculator for the entire process. The teacher demonstrates that most terms in the factorials cancel out, leaving only the multiplication of the last two terms, 24 and 25, resulting in 600. This method simplifies the process by avoiding unnecessary calculations.
