在传统的数学问题中,所给出的条件和结论大都是完备、确定的解题者只能依据题目的条件(当然也包括隐含条件),通过合理的演算或科学的论证,从而求得或证实题目所指定的结论;而与题目紧密相关的其他可能情况,则解题者可不予考虑诚然,做这类问题的练习,作为数学教学中的重要内容, In the traditional mathematics problems, the given conditions and conclusions are mostly complete and definitive. The solver can only obtain the problem based on the conditions of the problem (including implicit conditions, of course), through reasonable calculations or scientific arguments. Or confirm the conclusions specified by the topic; and in other possible situations that are closely related to the topic, the solver may not consider the practice of such questions as an important part of mathematics teaching.
