提高解题中的变形能力,对于提高运算能力以及利用运算进行推理的能力,是非常重要的一个方面。本文仅就中学生解题过程中常见的几种变形,谈些粗浅看法。 一关于数和式的分解变形 在解运算题或证明题时,经常需要进行数或式的组合变形与分解变形。由于历来教学中重视组合变形而忽视
Improving the deformability in problem solving is a very important aspect for improving the computing ability and the ability to use computations for reasoning. This article only discusses some of the common distortions in the process of solving problems for middle school students. A decomposition of the number and type of equations In solving problems or proofs, often need to perform a number or combination of deformation and decomposition of the deformation. Due to the emphasis on portfolio distortion in the past teaching
