N2  - Permutations and combinations is concerned with determining the number of different ways of arranging and selecting objects out of a given number of objects, without actually listing them. A permutation involves an arrangement of objects in a definite order while A Combinations On the other hand is not interested in arranging but only in selecting r objects from given n objects. A combination is a selection of some or all of a number of different objects where the order of selection is not important. In this Manuscript we are concerned about solving equations of permutation and combination, on how to determine n number of items and how it can be selected or arranged in r number of ways and also to introduce Anekwe’s method of swapping factorials in the case of determining r number of items.
