I. Combination formula and parting calculation

( 1)3×3=9 (2)45÷9=5 (3)9×3=27 (4)32-28=4 9+20=29 5+37=42 100-27=73 4×8=32

(5)5×4=20 (6)36÷4=9 (7)9×8=72 (8)4×2=8

20+80= 100 30-9=2 1 72+ 12=84 40÷8=5

(9)30-22=8 ( 10)8×3=24 ( 1 1) 15÷3=5 ( 12)40÷5=8 72÷8=9 56-24=32 25÷5=5 15-8=7

( 13)6×3= 18 ( 14) 13-7=6 ( 15) 1 1+20=3 1 ( 16)39- 12=27

18÷2=9 30÷6=5 55-3 1=24 27÷3=9

Second, off-model calculation.

( 1)63-40+25 (2)35+4×8 (3)27+8 1÷9 (4)6×8-24

(5)36÷6×4 (6)49÷7+63 (7)32+6×4 (8)90-64÷8

( 10)59-4×7 ( 1 1)6×(35÷5) ( 12)42÷( 18÷3)

( 13)(24+6)÷5 ( 14)3×7+50 ( 15)84-(45+5) ( 16)9×7+24

( 17)(48-39)×8 ( 18)48+8 1÷9 ( 18)94-7×9 (20)87-63+20
