数学开放型题相对于传统的条件完备、结论确定的封闭型题而言,往往与问题有关、无关的条件交织在一起,究竟哪些条件无用,需要去取舍,缺少的条件需要去挖掘;或一个问题可能多个结果,有时几个结果有优劣,暂时不能取舍,需要我们去进一步研究。对问题的条件、结论比较、分析、判断, The open question of mathematics is related to the traditional closed-ended questions with complete conditions and conclusions. It is often intertwined with problems-related and unrelated conditions. What conditions are useless, need to be chosen, and the missing conditions need to be excavated; or The problem may have multiple results. Sometimes, several results are pros and cons. For the time being, it is not acceptable. We need further study. The conditions, conclusions, comparisons, analysis, and judgments of the problems,
