解答(包括证明,下同)数学题,是运用已有的数学知识和已掌握的技能、技巧获取或者巩固新的知识和技能、技巧的实践活动.解题策略,是指为实现解题目标而确定的方针和方法.对于有些题目来说,由于其解法不是唯一的,需要我们对各种解法进行分析、比较和鉴别,即对各种解法的优劣进行策略评价,以便择优而从.一、对解题策略自觉地有意识地进行评价,是巧解数学题,实现解题方法合理化、最优化的重要手段.
Answer (including proof, the same below) math problems, is the use of existing math and acquired skills, skills to acquire or consolidate new knowledge and skills, skills and practical activities. Problem-solving strategies, is to achieve the purpose of solving problems For certain topics, because of its solution is not the only, we need to analyze, compare and identify the various solutions, that is, the advantages and disadvantages of various solutions for strategic evaluation, in order to choose from. First, the problem-solving strategy to consciously and consciously evaluate, is a clever solution to mathematical problems, to achieve problem-solving method of rationalization, an important means of optimization.
