We understand its applications and solve some problems involving its simplifications. First we notice factorials, then define it while noting its notation. We then practice identifying and evaluating a few common factorials. After going through some key observations, we practice simplifying expressions and solving equations involving factorials. We finally observe that the formula for rearrangements when all objects are distinct (and also when some objects are similar) contain our beloved factorial!
