解答算术应用題通常要經过五个步驟,即:审题、分解、解答、答題和檢查驗算。每一步驟各有其重要性,彼此相互关联。而分解这一步对整个解答过程是否正确經常起决定作用,因而成为一道重要关口。将应用題进行分解,不仅要求具有相应的知識和技能,而且要求具有相应的分析推理能力和正确的分解方法;特別是在解答一般复合应用題时,分解这一步经常是整个解答过程中的难点。 Answer arithmetic application questions usually go through five steps, namely: exam questions, decomposition, answer, answer and check checking. Each step has its own significance and is related to each other. The decomposition of this step on the whole process is often correct answer to play a decisive role, which has become an important juncture. Decomposition of the application of the problem, not only requires the corresponding knowledge and skills, but also requires the corresponding analytical reasoning ability and the correct decomposition method; especially in the solution of general composite questions, the decomposition of this step is often the difficulty of the entire solution process .
