数学开放性习题又叫数学开放题,是相对传统的封闭型习题(条件完备、结论确定)而言的。一个数学问题如果它的条件不完备,答案不唯一或者解决问题的方法不唯一,那么这个问题就可称之为数学开放题。数学开放题现在大约有3种定义:(1)答案不确定的数学问题称为开放题;(2)条件不完备、结论不确定的数学问题称为开放题;(3)数学开放题是指条件开放(条件在不断变化)、结论开放(多结论或无结论)、策略开放(可以采用多
Open math exercises, also known as mathematics open question, is a relatively traditional closed-type exercises (conditions are complete, the conclusion of the conclusion) is concerned. A mathematical problem if its conditions are incomplete, the answer is not unique or the method of solving the problem is not unique, then the problem can be called an open question of mathematics. Mathematical open questions now have about three kinds of definitions: (1) mathematical problems with uncertain answers are called open questions; (2) mathematics questions with incomplete conditions and inconclusive conclusions are called open questions; (3) mathematical open questions refer to Conditions are open (changing conditions), conclusions are open (many conclusions or no conclusion), strategy is open (can be used more
