任宏硕先生是中国科学院数学研究所的研究员。一般说,已经到了科学宝塔尖里的专家不会再回盼小学生的“启蒙”数学。然而由于任先生的坎坷经历,他便有了一个独特的视角;那些高深抽象的代数和小学生的加减乘除之间便有了一个独特的接触点。这个接触点是由他正上小学的儿子焊接的。而他的儿子便成为最早的受益者——北京海淀区数学奥林匹克学校的优秀学生。最近,任先生整理阐发了他的想法并将在本刊陆续登载他精心设计的题目。愿这些题目成为一块
Mr. Ren Hongshuo is a researcher at the Institute of Mathematics, Chinese Academy of Sciences. In general, experts who have reached the tip of a scientific pagoda will no longer look forward to “primary” mathematics. However, due to Mr. Ren’s rough experience, he had a unique perspective; there was a unique point of contact between the highly abstract algebra and the addition, subtraction, multiplication and division of pupils. This contact point was welded by the son he was attending elementary school. And his son became the earliest beneficiary - an outstanding student of the Beijing Mathematical Olympiad School in Haidian District. Recently, Mr. Ren organized and expounded his ideas and will publish his well-designed topics in the journal. May these topics become a piece of
