An attempt is made to reduce a fraction by canceling individual digits in the numerator and denominator. This is not a legitimate operation, and does not in general give a correct answer, but in some rare cases the result is numerically the same as if a correct procedure had been applied. The trivial case of canceling trailing zeros is ignored. Examples of anomalous cancellations which still produce the correct result include (these and their inverses are all the cases in base 10 with the fraction different from 1 and with two digits): : $\backslash frac\; =\; \backslash frac\; =\; \backslash frac\; =\; 4$ : $\backslash frac\; =\; \backslash frac\; =\; \backslash frac$ : $\backslash frac\; =\; \backslash frac\; =\; \backslash frac$ : $\backslash frac\; =\; \backslash frac\; =\; \backslash frac\; =\; 2.$〔Boas, R. P. "Anomalous Cancellation." Ch. 6 in ''Mathematical Plums'' (Ed. R. Honsberger). Washington, DC: Math. Assoc. Amer., pp. 113–129, 1979.〕 The article by Boas analyzes two-digit cases in bases other than base 10, e.g., 32/13 = 2/1 and its inverse are the only solutions in base 4 with two digits.〔 The anomalous cancellation happens also with more digits, e.g. 165/462 = 15/42. ==References== 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「Anomalous cancellation」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.
