This short article aims to present the Double Counting method as a resource to use in proof and to use some mathematical statements.Various arguments are constructed for practical problems in the middle, and their solutions are applied to mathematical results, sometimes not trivial, using double counting.The relevance of the study lies in the fact that it is an extremely simple idea, anchored in interesting solutions to some problems, which are provided for non-trivial statements.
