27-9= 30÷5= 42+6= 8+23= 64÷8= 49-7=
82﹢8= 8×8= 56÷8= 35+7= 16÷4= 7÷7= 6×7= 8÷2= 48-9= 40+3= 81-9= 63-23= 24÷6= 6×9= 32÷8= 9÷3= 72-9= 4÷2= 54÷9= 42÷7= 27÷3= 97-42= 39+7= 8×8= 36÷6= 27÷9= 21÷7= 42÷6= 12÷3= 30+25= 18-6= 5+5= 9×7= 24÷4= 7×6= 8÷8= 1
28÷7= 7+58= 8×6= 9÷3= 51-7= 63÷9= 24÷8= 28÷4= 46+9= 6×6= 35÷7= 67-15= 3×6÷2= 54÷9×8= 24-8÷2= 18+9÷3= 28÷4= 4+2×2= 18÷6= 25+13= 46-30= 28÷4= 2÷1= 16÷2= 74+21= 35÷5= 7×8= 20÷4= 24÷4= 46+8=
二、填空。
( )×( )=24 ( )×( )=24 ( )×( )=24 ( )×( )=24
( )÷( )=3 ( )÷( )=3 ( )÷( )=3 ( )÷( )=3
三、 用递等式计算。
5×7-8 35+25-16 24-8÷2
= = = = = =
16÷2÷4 (18+27)÷9 18+9÷3 = = = = = =
56+12-49 28÷7×9 = = = =
28–7×3 9+6÷3 = = = =
四、笔算。
46+57= 60-27= 82-55=
35+24-18 90-23-18= 61-36+47=
39+15= 71–92= 9+53–62=
将下列算式填在合适的( )里。
