小学数学二年级口算竞赛试题

8×6= 72 + 19 = 6 ÷1 = 180÷180= 48÷8 =

45 + 37 = 4×7= 550-550= 500-370= 25 + 75 =

55 +88 = 3200 -700= 69+24= 350-80 = 77 + 66 =

790 + 130 = 87-29= 800-330 = 99+11= 257-257=

65 + 35 = 69 ÷ 8 = 92 + 46 = 46÷7 = 50÷6=

0 ÷ 8 = 39 ÷ 9 = 93-39 = 86-68= 1000-300=

29+63= 54-45 = 7 ×7 = 75 ÷ 9 = 81÷9 =

800-260= 86×0= 470-80 = 55÷7 = 38 + 52 =

250+630= 77 + 33 = 380+70= 500-490= 66÷7 =

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(65438+每题0分，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)=

三。计算(每题2分，16分)

7×8×0×9+9×8= 1+2+3+4+5+6+7+8+9=

81-9-9-9-9-9-9= 15+15+15+15+15+15=

89+89-89+89-89= 64-5×8-2× 8=

147+148+149+150+151+152+153= 1+2+3+4+5+6……+94+95+96+97+98+99=
