2026年亮点给力计算天天练二年级数学下册苏教版第72页答案
1. 直接写出得数。
210 + 90 = 300 - 70 = 910 - 40 = 82 - 37 + 24 =
600 + 70 = 25 + 39 = 7800 - 800 = 71 - 28 + 30 =
61 - 32 = 73 + 27 = 6700 - 6000 = 83 - 47 + 11 =
22 × 3 = 4500 + 500 = 450 + 80 = 150 - 70 + 30 =
92 - 43 = 3300 - 400 = 1230 + 70 = 6 × 7 + 14 =
25 - 16 = 300 - 70 = 930 - 200 = 85 - 50 + 28 =
99 ÷ 9 = 1560 - 600 = 5700 - 5000 = 7000 + 700 + 300 =
3200 + 300 = 290 - 80 = 400 + 20 = 6600 - 600 + 400 =
