一、口算。
2 + 9 = 13 - 5 = 34 - 30 =
89 - 9 = 20 + 60 = 8 + 40 =
4 + 50 = 14 - 10 = 80 - 30 =
17 - 9 = 9 + 7 = 60 + 7 =
5 + 90 = 74 - 70 = 56 - 6 =
18 - 9 = 70 + 20 = 9 + 9 =
6 + 8 = 45 - 5 = 63 - 3 =
70 - 10 = 3 + 40 = 30 + 7 =
50 + 5 = 11 - 9 = 65 - 5 =
83 - 80 = 20 + 4 = 8 + 50 =
2 + 9 = 13 - 5 = 34 - 30 =
89 - 9 = 20 + 60 = 8 + 40 =
4 + 50 = 14 - 10 = 80 - 30 =
17 - 9 = 9 + 7 = 60 + 7 =
5 + 90 = 74 - 70 = 56 - 6 =

6 + 8 = 45 - 5 = 63 - 3 =
70 - 10 = 3 + 40 = 30 + 7 =
50 + 5 = 11 - 9 = 65 - 5 =
83 - 80 = 20 + 4 = 8 + 50 =
