一 口算题。
81 - 56 = 280 - 190 = 34 + 48 = 200 ÷ 40 =
175 ÷ 35 = 30 × 56 = 309 × 4 = 170 + 320 =
140 × 40 = 300 ÷ 4 = 520 ÷ 13 = 48 × 20 =
412 ÷ 2 = 72 + 28 = 81 - 39 = 12 × 50 =
67 - 28 = 560 ÷ 14 = 656 ÷ 8 = 700 ÷ 70 =
480 ÷ 3 = 160 × 40 = 37 × 40 = 32 × 6 =
910 - 190 = 22 × 200 = 27 × 30 = 360 ÷ 4 =
350 × 2 = 180 ÷ 30 = 240 ÷ 40 = 123 + 15 =
370 + 580 = 240 ÷ 2 = 420 - 80 = 55 ÷ 5 =
104 × 5 = 90 ÷ 30 = 270 ÷ 30 = 190 ÷ 2 =
480 ÷ 40 = 11 × 80 = 240 + 570 = 35 × 200 =
75 × 100 = 920 ÷ 40 = 480 ÷ 16 = 189 + 279 =
