In this technique, which call “one of the most important tools in combinatorics,” one describes a finite set ''X'' from two perspectives leading to two distinct expressions for the size of the set. Since both expressions equal the size of the same set, they equal each other. ==Examples== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Double counting (proof technique)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
