1、小学生小升初数学常见简便计算总结分析与解在进行四则运算时,应该注意运用加法、乘法的运算定律,减法、除法的运算性质,以便使某些运算简便。本题就是运用乘法分配律及减法性质使运算简便的。 例1、 例2计算9999×2222+3333×3334 分析与解利用乘法的结合律和分配律可以使运算简便。 9999×2222+3333×3334 =3333×(3×2222)+3333×3334 =3333×6666+3333×3334 =3333×(6666+3334) =3333×10000 = 分析与解将分子部分变形,再利用除法性

7、分母分别分解质因数,这样计算比较简便。 分析与解通过观察发现,原算式是求七个分数相加的和,而这七个分这可让他犯了难,施工现场距离项目部很远,没有车还真是不方便office,branchoffices(jurisdiction),riskmanagement,marketingmanagementsectorthroughsupervisionandinspectionfoundproblems,shouldbeassignedtheinvestigatorsarecorrectedinatimelyman
