答案： 解析：题目考查的是小数的加减法速算，直接进行数值计算即可。
答案：
2 + 2.6 = 4.6
0.7 + 3 = 3.7
0.29 + 2 = 2.29
0.15 + 1 = 1.15
3.24 + 0 = 3.24
6 + 3.4 = 9.4
2.8 + 3 = 5.8
7.4 - 4 = 3.4
7.4 - 0.4 = 7
2.5 - 2 = 0.5
4.9 - 4 = 0.9
4.9 - 3 = 1.9
2.11 + 1 = 3.11
0.37 + 2 = 2.37
9 + 0.52 = 9.52
0.5 + 8 = 8.5
12 + 0.4 = 12.4
7 + 0.3 = 7.3
7.3 - 3 = 4.3
17.3 - 7 = 10.3
2.4 - 2 = 0.4
0.28 + 2 = 2.28
3.25 - 2 = 1.25
7.36 - 5 = 2.36
2 + 3.7 = 5.7
7 + 3.7 = 10.7
10.7 - 3 = 7.7
0.56 + 4 = 4.56
8.7 - 7 = 1.7
8.7 - 0.7 = 8
9.4 - 4 = 5.4
9.4 - 9 = 0.4
3.78 - 3 = 0.78
12.55 - 10 = 2.55
12.9 - 0.9 = 12
12.9 - 2 = 10.9
7.4 - 4 = 3.4
2.8 - 2 = 0.8
2.2 - 0.2 = 2
2.2 + 0.8 = 3
