一、口算。
35 + 5 = 6 + 57 = 62 - 30 + 9 =
95 - 80 = 44 - 5 = 8 + 53 + 30 =
20 + 48 = 35 + 20 = 85 + 6 - 40 =
71 - 3 = 26 - 8 = 50 - 3 - 9 =
20 + 75 = 38 - 20 = 27 + 3 + 41 =
68 - 30 = 63 + 8 = 72 + 20 - 8 =
6 + 36 = 30 - 8 = 54 - 5 - 30 =
44 - 40 = 79 + 20 = 35 - 6 + 50 =
3 + 37 = 55 - 5 = 20 + 36 - 8 =
62 - 40 = 67 + 8 = 80 - 5 + 4 =
