This math topic revolves around manipulating factorial expressions and calculating the value of permutations. It introduces permutations using the nPm notation, where "n" is the total number of items and "m" specifies a subset, focusing on fundamental problems to determine the correct value of given permutation formulas. These problems involve straightforward factorial calculations and their ratios, engaging students in factorial operation understandings such as "5!", "4! over 2!", and straightforward numerical results from these operations. This builds a foundational skill set in permutations necessary for deeper study in probability and statistics.
