一、直接写出得数。（共32分）
810 - 370 = 182 + 418 = 69 + 231 = 72 ÷ (22 - 14) =
108 × 5 = 464 ÷ 4 = 37 × 40 = 23 × (82 - 62) =
99 - 39 = 29 × 5 = 20 × 80 = 648 ÷ 2 ÷ 4 =
268 ÷ 4 = 66 × 6 = 220 × 6 = 3200 - 1400 + 800 =
73 × 40 = 130 × 9 = 60 × 18 = 270 ÷ 3 + 50 =
40 × 65 = 340 ÷ 4 = 155 + 65 = 30 + 350 ÷ 5 =
57 × 11 = 87 - 19 = 616 ÷ 4 = (42 - 16) × 20 =
17 × 70 = 700 ÷ 5 = 980 ÷ 7 = 70 - (26 + 13) =

一 440 600 300 9 540 116 1480 460 60 145 1600 81 67 396 1320 2600 2920 1170 1080 140 2600 85 220 100 627 68 154 520 1190 140 140 31

二、用竖式计算，带☆的要验算。（共19分）
72 × 29 = 80 × 64 = ☆31 × 95 =
53 × 48 = 16 × 77 = 48 × 69 =

二 2088 5120 2945 2544 1232 3312 竖式及验算略

三、计算下面各题。（共18分）
24 × 41 - 325 (665 - 578) × 17 765 ÷ (125 - 116)
504 ÷ (28 ÷ 4) 38 × (156 - 98) 920 - 24 × 13

三 659 1479 85 72 2204 608
