严保艳19464238492 ______ 1.25*2.5*3 =1.25*2.5*4*8 =(4*2.5)*(8*1.25) =10*10 =100

隗香音210412.5x2.5x0.32的简便方法是什么 -
严保艳19464238492 ______ 12.5x2.5x0.32=12.5x2.5x(0.8x0.4)=(12.5x0.8)x(2.5x0.4)=10x1=10

隗香音21041.25*32 简便运算 -
严保艳19464238492 ______ 方法一: 1.25 * 32 = (1 + 0.25) * 4 * 8 = ( 4 + 1) * 8 = 40 方法二: 1.25 * 32 =1.25*8*4 =10*4 =40 扩展资料: 加法:a+b=b+a(加法交换律) a+b+c=a+(b+c) (加法结合律) a+99=a+(100-1)(近似数) 乘法:a*b=b*a(乘法交换律) a*b*c=a*(b*c)(乘法结合律) (a+b)*c=a*c+b*c(乘法分配律) (a-b)*c=a*c-b*c(乘法分配律变化式) (a+b+d)*c=a*c+b*c+d*c(乘法分配律变化式) a*c+c=(a+1)*c(乘法分配律变化式)
