19 - 3 = 11 + 4 = 13 + 1 = 4 + 3 + 5 =
3 + 15 = 15 - 5 = 10 + 6 = 10 - 2 + 6 =
18 - 7 = 3 + 9 = 1 + 14 = 15 + 4 - 7 =
8 + 9 = 14 - 10 = 10 + 8 = 17 - 0 - 4 =
17 + 2 = 18 - 8 = 8 + 2 = 12 + 4 - 6 =
16 - 6 = 15 + 0 = 7 + 7 = 11 + 6 - 3 =
19 - 0 = 5 + 12 = 4 + 9 = 18 - 5 - 3 =
10 - 7 = 9 + 7 = 12 - 10 = 8 + 9 - 17 =
19 - 8 = 7 + 5 = 14 - 1 = 10 - 4 + 9 =
9 + 8 = 16 - 5 = 6 + 13 = 15 - 5 - 5 =
19 - 3 = 11 + 4 = 13 + 1 = 4 + 3 + 5 =
3 + 15 = 15 - 5 = 10 + 6 = 10 - 2 + 6 =

2. 在□里填上合适的数。(建议用时3分钟)
6 + □ = 14 □ - 3 = 11 □ + 12 = 15
□ - 10 = 6 □ + 8 = 10 10 - □ = 4
13 + □ = 16 19 - □ = 14 9 + □ = 18
17 - □ = 13 □ + 10 = 11 □ - 0 = 17
6 + □ = 14 □ - 3 = 11 □ + 12 = 15
□ - 10 = 6 □ + 8 = 10 10 - □ = 4
13 + □ = 16 19 - □ = 14 9 + □ = 18
17 - □ = 13 □ + 10 = 11 □ - 0 = 17
