为了提高中学数学教学的貭量,为了使数学教学符合多快好省的方針,代数中恒等变形的內容、要求和安排,是大家热烈討論的問題之一。对于这个問題,我們也有一些想法,提出来同大家討論。其中不妥之处,請批評指正。一、恒等变形的作用代数中的恒等变形,是学习代数中其它內容的基础,也是学习其它数学的基础。就代数中的方程来說,为了学习一元一次方程,就需要有整式运算的基础;学习一元二次方
In order to improve the teaching of mathematics in middle school, in order to make mathematics teaching accord with the principle of “more efficient and more economical”, the content, requirement and arrangement of equal deformation in algebra are one of the hot topics for discussion. We also have some ideas on this issue that we propose to discuss with everyone. One of the inappropriate, please comment on criticism. First, the role of equal deformation The equal deformation in algebra is the basis for learning other content in algebra, but also learning the basis of other mathematics. In algebraic equations, in order to learn a one-time equation, you need to have the basis of integer operations; learning a quadratic
