8.7×1.6+4.64
=8.7×1.6+4.64+0.16-0.16
=8.7×1.6+3*1.6-0.1*1.6
=（8.7+2.9）*1.6
=（8.7+1.3）*1.6+1.6*1.6
=10*1.6+1*1.6+0.6*1.6
=16+1.6+0.96
=16+1.6+1-0.04
=18.56
8.7×1.6+4.64=8.7×1.6+4.64+0.16-0.16
=0.87*16+0.29*16
=1.16*16
=16+1.6+0.96
=16+1.6+1-0.04
=18.56
=8.7×1.6+4.64+0.16-0.16
=8.7×1.6+3*1.6-0.1*1.6
=（8.7+2.9）*1.6
=（8.7+1.3）*1.6+1.6*1.6
=10*1.6+1*1.6+0.6*1.6
=16+1.6+0.96
=16+1.6+1-0.04
=18.56
8.7×1.6+4.64=8.7×1.6+4.64+0.16-0.16
=0.87*16+0.29*16
=1.16*16
=16+1.6+0.96
=16+1.6+1-0.04
=18.56
