解题就是从未知到已知的转化,审题是关键,观察题目的已知条件和解题目标,看清题目的结构特征,为选择解法提供决策的依据,特别在数学问题中,条件有明有暗,明者易于发现,便于利用;暗者隐含于有关概念、知识的内涵之中,含而不露,极易忽视,稍不留心,便导致解题出错.这些隐含条件,在题目中是没有直接、明显给出的固有条件,它有待于解题者从题设、结论的语言、数或图形的特征或相关知识的联系上去剖析发掘.所以从某种意义上说,解数学题是一个从题目所列条件 The problem-solving problem is the conversion from the unknown to the known one. The problem-solving problem is the key. Observing the known conditions and problem-solving objectives of the problem, and seeing the structural features of the problem, provide the basis for the decision-making of the selected solution, especially in the mathematics problem. Dark, easy to find, easy to use; dark hidden in the connotation of the concept, knowledge, with no disclosure, easy to ignore, do not pay attention, it will lead to errors in the problem. These implicit conditions, in the title There is no inherent condition that is directly and clearly given, and it needs to be analyzed and explored by the problem solver in terms of the language of the question, the language of the conclusion, or the characteristics of the figure or related knowledge. So in a sense, the solution to mathematics The title is a list of conditions from the title
