第四篇:人教版五年级数学简便计算归纳
小学数学简便运算归类练习
A、一般情况下,四则运算的计算顺序是:有括号时,先算,没有括号时,先算,再
算,只有同一级运算时,从左往右。
B、运用运算定律
加法交换律:a+b=b+a加法结合律: a+b+c=a+(b+c)
乘法交换律:a×b=b×a乘法结合律:a×b×c=a×(b×c)乘法分配律:(a+b)×c=a×c+b×c
C、减法性质:a-b-c=a-c-b=a-(b+c)除法性质:a÷b÷c=a÷c÷b=a÷(b×c)
一、当一个计算题只有同一级运算(只有乘除或只有加减)又没有括号时,我们可以随意“带符号搬家”
12.06+5.07+2.9430.34+9.76-10.3425×7×434÷4÷1.7
102×7.3÷5.141.06-19.72-20.287.2+2.2×1.22.6÷1.3+8.7
B、当同级运算需加括号或去括号时,即加或去括号时,括号前是加或乘号,可以直接加或去括号,而括
号前是减或除号,括号里要变号
700÷14÷518.6÷2.5÷0.41.06×2.5×45.68+(5.39+4.32)
19.68-(2.97+9.68)1.25×(8÷0.5)0.25×(4×1.2)1.25×(213×0.8)
三、乘法分配律的两种典型类型
A,、括号里是加或减运算,与另一个数相乘,注意分配
0.4×(0.25+2.5)(12+1.2)×0.2(40-1.25)×0.8
B、注意相同因数的提取。
0.92×1.41+0.92×8.597.8×9.9+9.9×2.21.3×11.6-1.6×1.311.9×9.9+1.19×
