1995年元旦是星期日,再过2~(1995)天是星期几? 贵刊文[1]从以上趣题出发,通过分析、归纳并证明了如下猜想: (1)再过2~(3m)天是星期一; (2)再过2~(3m+1)天是星期二; (3)再过2~(3m+2)天是星期四.(其中m为非负整数) 文[1]的论证是分别利用初中的“因式分解”和高中的“二项式定理”给出的.本文运用连小学生也能理解的二进制给予证明,不仅新颖别致,也算对文
The New Year’s Day in 1995 is Sunday, and what day is the second day in 2~(1995)? Your article [1] starts from the above interesting questions and analyzes, summarizes, and proves the following conjectures: (1) Another 2~(3m) Day is Monday; (2) Another 2~(3m+1) days is Tuesday; (3) Another 2~(3m+2) days is Thursday. (Where m is a non-negative integer) Text [1] The argumentation is given using the “factor factorization” of junior high school and the “binomial theorem” of high school. This paper uses a binary, which is understandable by elementary school students, to prove that it is not only novel and unique, but also verbatim.
