1. 直接写出得数。
230 - 40 = 210 - 109 = 704 + 216 = 64 - 64 ÷ 8 =
27 × 90 = 2200 - 1500 = 66 + 19 = 3 × 8 + 35 =
196 ÷ 7 = 910 × 7 = 303 ÷ 3 = 51 ÷ (29 - 26) =
860 ÷ 4 = 38 × 50 = 124 × 4 = 256 - 28 + 72 =
98 ÷ 2 = 595 ÷ 7 = 33 - 14 = 24 + 16 × 4 =
29 - 19 = 44 + 69 = 270 ÷ 5 = 96 ÷ (56 ÷ 7) =
30 × 32 = 24 × 50 = 21 × 90 = 45 × 20 ÷ 9 =
118 ÷ 2 = 201 ÷ 3 = 74 × 40 = 90 × (18 ÷ 9) =
230 - 40 = 210 - 109 = 704 + 216 = 64 - 64 ÷ 8 =
