2026年亮点给力计算天天练二年级数学下册苏教版第38页答案
一、直接写出得数。(每题1分,共32分)
75 - 38 = 9×3 = 54 - 29 = 40 - 12 - 18 =
56 - 26 = 44÷4 = 56 + 24 = 80÷4 - 15 =
28÷2 = 86÷2 = 99÷9 = 33×3 - 80 =
8×7 = 23×3 = 700 + 90 = 14×2 - 9 =
15 + 51 = 41×2 = 75 + 18 = 20×4 - 11 =
10×9 = 81÷9 = 260 - 60 = 66÷6 + 59 =
37 + 30 = 17 + 68 = 31 + 68 = 61 - 39 + 20 =
46 + 24 = 72 - 53 = 670 - 70 = 45 + 10 - 8 =

三、填一填。(每空2分,共24分)
(
300
) + 50 = 350 550 - (
50
) = 500 (
11
)×5 = 55
(
67
) - 29 = 38 (
70
)÷7 = 10 (
12
)×3 = 36
610 - (
600
) = 10 2×(
32
) = 64 (
46
) + 52 = 98
2×(
34
) = 68 (
22
)×4 = 88 59 - (
27
) = 32

答案

300 50 11 67
70 12 600 32
46 34 22 27
