9.6*(1+7+2)
=9.6*10
=96
2:
3.6*4.8-3.9
=3.6*(4.8-1)-0.3
=3.6*3.8-0.3
=13.68-0.3
=13.38
9.6+9.6×7+2×9.6
=9.6x(1+7+2)
=9.6x10
=96
给我加分
1.9.6+9.6×7+2×9.6
=9.6×(1+7+2)
=9.6×10
=96

这题,你确定没抄错?
没有简便方法
9.6*(1+7+2)
=9.6*10
=96
2:
3.6*4.8-3.9
=3.6*(4.8-1)-0.3
=3.6*3.8-0.3
=13.68-0.3
=13.38
第一题:原式=9.6*(1+7+2)
