A brief guide to solving permutations is presented. Permutations relate to the quantification of possible arrangements of objects. The permutation formula, denoted by nPr = n! / (n-r)!, is typically utilized. Here, 'n' stands for the total number of items, and 'r' represents the items to be selected. The symbol '!' signifies factorial, which is the multiplication of all positive integers up to the mentioned number.
