1.直接写出得数。
43 + 12 = 32 + 52 = 16 + 51 = 17 + 62 =
45 - 38 = 63 + 17 = 27 + 48 = 52 - 16 =
44 - 18 = 57 - 29 = 45 + 23 = 34 + 27 =
17 + 8 + 21 = 45 - 13 - 21 = 85 - 46 + 46 =
45 - 24 + 19 = 15 + 47 - 12 = 78 - 24 + 24 =
35 + 40 - 21 = 51 - 31 + 23 = 67 + 17 - 40 =
43 + 12 = 32 + 52 = 16 + 51 = 17 + 62 =
45 - 38 = 63 + 17 = 27 + 48 = 52 - 16 =
44 - 18 = 57 - 29 = 45 + 23 = 34 + 27 =
17 + 8 + 21 = 45 - 13 - 21 = 85 - 46 + 46 =
45 - 24 + 19 = 15 + 47 - 12 = 78 - 24 + 24 =
35 + 40 - 21 = 51 - 31 + 23 = 67 + 17 - 40 =
答案：
55 84 67 79 7 80 75 36
26 28 68 61 46 11 85
40 50 78 54 43 44
26 28 68 61 46 11 85
40 50 78 54 43 44
2.用竖式计算。
70 - 45 + 28 = 52 - 29 + 68 = 26 + 35 - 47 =
91 - 32 + 19 = 27 + 58 - 73 = 24 + 39 - 17 =
70 - 45 + 28 = 52 - 29 + 68 = 26 + 35 - 47 =
91 - 32 + 19 = 27 + 58 - 73 = 24 + 39 - 17 =
答案：
（过程略）53 91 14 78 12 46
