1. 口算。(建议用时6分钟)
17 - 7 = 11 + 2 = 7 + 9 = 6 + 5 - 9 =
1 + 9 = 12 - 9 = 2 + 14 = 15 - 2 - 9 =
18 - 5 = 13 - 2 = 11 - 9 = 12 - 9 + 7 =
2 + 9 = 15 - 9 = 7 + 12 = 18 - 9 + 6 =
19 - 1 = 13 + 5 = 13 - 9 = 19 - 4 - 9 =
9 + 3 = 16 - 9 = 5 + 9 = 11 + 8 - 9 =
17 - 9 = 15 - 4 = 9 + 9 = 13 + 1 - 9 =
16 - 1 = 13 + 6 = 17 - 5 = 16 - 9 + 11 =
9 + 4 = 17 - 4 = 18 - 9 = 7 + 8 - 9 =
14 - 9 = 14 - 3 = 9 + 6 = 17 - 9 - 5 =
18 - 4 = 6 + 5 = 10 - 2 = 9 - 3 + 6 =
6 + 7 = 15 - 3 = 3 + 13 = 4 + 7 + 7 =
