1. 直接写出得数。
74 + 28 = 99 ÷ 3 = 180 + 270 = 120 ÷ (4 ÷ 2) =
60 × 17 = 69 × 3 = 964 ÷ 4 = 848 ÷ 8 - 48 =
1400 - 700 = 132 ÷ 4 = 142 - 22 = 99 × 2 + 18 =
53 × 20 = 19 × 30 = 208 ÷ 4 = 4 × 6 × 4 =
256 ÷ 4 = 210 × 6 = 360 × 0 = 12 × 40 - 80 =
459 ÷ 9 = 33 × 50 = 80 × 15 = 25 + 5 × 13 =
24 + 80 = 49 × 30 = 210 × 4 = (140 - 40) ÷ 2 =
690 ÷ 6 = 44 - 17 = 213 ÷ 3 = 2800 - 1400 + 200 =
