一、口算。(每题1分,共27分)
52 - 31 = 7×9 = 540 + 80 =
250 + 70 = 32 + 29 = 20×3 =
240 - 90 = 11×9 = 160 - 70 =
800 + 300 = 72 - 44 = 88÷8 =
27 + 67 = 23×3 = 420 - 60 =
28÷4 = 230 + 90 = 180 + 130 =
440 - 80 = 40÷8 = 380 - 90 =
62÷2 = 280 + 80 = 71 - 43 =
4×12 = 63÷3 = 34×2 =

答案

一、21 63 620 320 61 60 150 99 90 1100 28 11 94 69 360 7 320 310 360 5 290 31 360 28 48 21 68
二、在(
31
)里填合适的数。(每题2分,共24分)
(
31
)÷9 = 3……4 28 + 28 = (
8
)×7
(
30
)÷4 = 7……2 320 + 430 = (
970
) - 220
(
32
)×2 = 8×8 72 - (
28
) = 4×11
120 - 80 = 5×(
8
) (
310
) - 90 = 140 + 80
96÷3 = (
64
)÷2 62÷(
7
) = 8……6
(
170
) + 70 = 330 - 90 420 - (
70
) = 170 + 180

答案

二、31 8 30 970 32 28 8 310 64 7 170 70
