一、口算:
32÷8= 8×7= 5×9= 32+41= 73-17=
27+15= 36+5= 3+29= 16+50= 41-6=
9×3-20= 45÷9+12= 100-8×8= 56 ÷8=
50-5×8= 65-8×8= 39+7÷7= 6×8=
二、脱式计算 :
4×7+22 (20-12)×2
= =
= =
72÷8+54 61-9×6
= =
= =
18÷2+35 60-7×6
= =
= =
32÷8+17 64÷8-6
= =
= =
26-12+47 32÷8×9
= =
= =
70-40÷8 53-(16+19)
= =
= =
(45-36)×9 72÷(32-24)
= =
