: ''Abstract algebra has an unrelated term word problem for groups.'' In mathematics education, the term word problem is often used to refer to any mathematical exercise where significant background information on the problem is presented as text rather than in mathematical notation.〔L Verschaffel, B Greer, E De Corte (2000) ''Making Sense of Word Problems'', Taylor & Francis〕 As word problems often involve a narrative of some sort, they are occasionally also referred to as ''story problems'' and may vary in the amount of language used.〔John C. Moyer; Margaret B. Moyer; Larry Sowder; Judith Threadgill-Sowder (1984) ''Story Problem Formats: Verbal versus Telegraphic'' Journal for Research in Mathematics Education, Vol. 15, No. 1. (Jan., 1984), pp. 64-68. http://links.jstor.org/sici?sici=0021-8251%28198401%2915%3A1%3C64%3ASPFVVT%3E2.0.CO%3B2-V〕 == Example == A mathematical problem in mathematical notation: : Solve for J: :: ''J'' = ''A'' − 20 :: ''J'' + 5 = (''A'' + 5)/2 might be presented in a word problem as follows: :''John is twenty years younger than Amy, and in five years' time he will be half her age. What is John's age now?'' The answer to the word problem is that John is 15 years old, while the answer to the mathematical problem is J = 15 (and A =35). 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「Word problem (mathematics education)」の詳細全文を読む スポンサード リンク
