1. 直接写出得数。
76 + 38 = 95 + 37 = 91 - 48 = 140 ÷ 2 ÷ 5 =
83 - 46 = 110 - 43 = 59 + 36 = 240 ÷ 4 × 0 =
19 × 4 = 106 ÷ 2 = 108 ÷ 6 = 400 ÷ 8 + 5 =
250 ÷ 5 = 405 ÷ 5 = 33 × 9 = 900 ÷ (54 - 45) =
660 ÷ 6 = 140 × 4 = 140 - 82 = 80 + 22 × 5 =
180 ÷ 3 = 728 ÷ 8 = 960 ÷ 8 = (358 + 42) × 5 =
76 ÷ 2 = 219 ÷ 3 = 52 × 3 = 146 - 47 × 2 =
27 × 4 = 77 × 5 = 87 × 4 = 28 × 5 + 5 =
