Question

13．加數(shù)=和-另一個加數(shù) 減數(shù)=被減數(shù)-差被減數(shù)=減數(shù)+差；
因數(shù)=積÷另一個因數(shù) 除數(shù)=被除數(shù)÷商被除數(shù)=除數(shù)×商．

Answer 1

分析 加數(shù)、和的關(guān)系：加數(shù)+加數(shù)=和，加數(shù)=和-另一個加數(shù)；被減數(shù)、減數(shù)、差的關(guān)系：被減數(shù)-減數(shù)=差，被減數(shù)=減數(shù)+差，減數(shù)=被減數(shù)-差；因數(shù)、因數(shù)和積的關(guān)系：因數(shù)×因數(shù)=積，積÷一個因數(shù)=另一個因數(shù)；被除數(shù)、除數(shù)和商的關(guān)系：被除數(shù)=除數(shù)×商，除數(shù)=被除數(shù)÷商，商=被除數(shù)÷除數(shù)；據(jù)此解答即可．

解答 解：加數(shù)=和-另一個加數(shù) 減數(shù)=被減數(shù)-差，被減數(shù)=減數(shù)+差；
因數(shù)=積÷另一個因數(shù)，除數(shù)=被除數(shù)÷商，被除數(shù)=除數(shù)×商．
故答案為：和-另一個加數(shù)；被減數(shù)-差；減數(shù)+差；積÷另一個因數(shù)；被除數(shù)÷商；除數(shù)×商．

點評 此題主要考查了加法和減法的互逆關(guān)系，以及乘法和除法的互逆關(guān)系的應(yīng)用，要熟練掌握．
