人教版小学数学三年级下册口算练习题
人教版小学数学三年级下册口算练习题57×3×0=0,因为任何数乘以0都等于0.22×22=484,这是22的平方。
20×5=100,这是20和5的乘积。
5×8-8=32,这是5乘以8再减去8.92×7=644,这是92和7的乘积。
960÷4÷2=120,这是960除以4再除以2.513×9=4617,这是513和9的乘积。
72-72÷6=60,这是72减去72除以6的结果。
8×9-7=65,这是8乘以9再减去7.300×30=9000,这是300和30的乘积。
110×35=3850,这是110和35的乘积。
8+2×10=28,这是8加上2乘以10的结果。
8×122=976,这是8和122的乘积。
91×31=2821,这是91和31的乘积。
5×5+4=29,这是5乘以5再加上4.27×8=216,这是27和8的乘积。
6×7+6=48,这是6乘以7再加上6.15×61=915,这是15和61的乘积。
5×80=400,这是5乘以80.27+15=42,这是27和15的和。
50-24÷4=44,这是50减去24除以4的结果。
