数学是思维的体操,它在培养和提高学生思维能力方面发挥着特殊作用,所有数学问题的处理过程都必然遵循普遍的规律;但要解决它的具体问题往往没有什么固定的模式可寻.在具体数学问题的解决过程中,一般都要经历一波三折,也正是在这种思维的曲折行进中,才使人们的思维得到了充分的展示和锻炼,这也正是数学学科的魅力所在.它山之石可以攻玉,不断转换问题的思考角度,是数学思维的一般方法,其中反客为主就是转换角度思考问
Mathematics is the gymnastics of thinking. It plays a special role in cultivating and improving the thinking ability of students. All the mathematical problems are bound to follow the universal law. However, there is often no fixed pattern to solve its specific problems. It is precisely the charm of mathematics that lies in the process of solving mathematical problems in general, and it is also in the twists and turns of this thinking that people’s thoughts are fully displayed and exercised. Mountain stone can attack jade, thinking of the problem of continuous conversion point of view, is the general method of mathematical thinking, which is the main anti-offensive thinking is to ask the conversion angle
