简便计算:960+16x0.64+9.84x64
简便计算:960+16x0.64+9.84x64

简便计算:960+16x0.64+9.84x64
960+16x0.64+9.84x64=960+0.16x64+9.84x64=960+10×64=960+640=1600

原式=960+(9.84+0.16)*64
=960+640
=1600

=960+16*0.64+984*0.64
=960+(16+984)*0.64
=960+1000*0.64
=960+640
=1600

960+16*0.64+984*0.64
=960+(16+984)*0.64
=960+1000*0.64
=960+640
=1600
