2026年亮点给力计算天天练二年级数学下册苏教版第16页答案
1. 直接写出得数。
26 + 37 = 71 - 38 = 27 + 28 = 48 - 33 + 26 =
58 - 19 = 92 - 56 = 44 - 29 = 18 + 29 - 19 =
46 + 32 = 66 - 37 = 81 ÷ 9 = 31 + 13 - 20 =
74 - 36 = 37 + 29 = 72 - 34 = 66 - 29 + 12 =
63 - 29 = 34 + 38 = 24 + 58 = 8 × 8 ÷ 8 =
37 + 43 = 65 - 38 = 24 ÷ 8 = 2 × 4 × 6 =
52 - 24 = 39 + 24 = 31 - 17 = 33 + 33 + 33 =
47 + 33 = 55 - 29 = 43 - 15 = 66 - 22 - 22 =
