整体与部分概念广泛地存在于小学数学知识中.“整”指整体,“零”指部分,整体可以分割成部分,部分组合成整体.要求整体量,可以先求出与整体量有关的部分量,即先“化整为零”求出部分量,再“聚零成整”求出整体量.反之,要求部分量,可以先求出与部分量有关的整体量,即先“聚零成整”求出整体量,再“化整为零”求部分量.下面分别探讨. Whole and part of the concept exists in the elementary mathematics knowledge. “Whole” refers to the whole, “zero” refers to the part, the whole can be divided into parts, part of the combination into a whole.Requirements of the overall quantity, you can first find the part and the amount of Quantity, that is, first “to zero” to find the part of the amount, and then “poly-zero into the whole” to find the overall amount. On the contrary, the required part of the amount, you can first find the partial amount and the amount of the whole, Integral “to find the overall amount, and then” consolidation "to seek part of the amount of the following discussion.
