由于“复数”在无线电、流体力学、测绘学等现代科学中有着广泛的应用,在中学阶段必须打好这方面的基础,因而全国统编教材提高了关于“复数”的要求,这是很必要的。学生在学习“复数”时不能很好系统概括,以感到内容不难而掉以轻心,但实际在解题时却往往出现差错,本文拟在教材内容的基础上对复数题加以归类,综合和提高,以便于复习时参考。 Since “plurality” has a wide range of applications in modern sciences such as radio, fluid mechanics, and surveying and mapping, it is necessary to lay a foundation for this in the middle school. Therefore, the national textbooks increase the requirements for “plurality,” which is necessary. of. Students are not able to summarize systematically when they are learning “plural numbers”. They feel that the content is not difficult to be taken lightly. However, they often make mistakes in solving problems. This paper intends to classify and categorize complex questions based on the content of teaching materials. For reference when reviewing.
