6 ÷ 6 =          95-68=                 0  ×9   =           27÷9=                    910-320=

73  + 37 =         0  ÷ 9 =                 680+220=           550+260=                   25÷4=

0  + 9 =           57-38=              8  ×  9   =             47÷8=             126-126=

 

二、计算(每题1分,计24分)

42+42÷7=               64÷8+70=                          500+320+80=                     60+60+60=           

8÷8×8=                   1300+700-1000=               30-30÷6=                   165-50-50=

273+35+65=                 120 + 395 + 80 =              90÷90×90=                 4000-3500 + 500= 

100-23-77=            165+165-165=                   65-(40-25)=               28÷7×6=

800+683-600=           45+36-45=                     5×8÷5=                      (27+36)÷7=  

650-599+250=            58+97-58=                   989-231+231=                 53-(48+5)=
