一、直接写出得数。
1.45 - 0.6 = 0.65 + 3.5 = 2.6 - 1.7 =
24.16 + 0.3 = 9.8 - 2.07 = 3.3 + 1.67 =
10 - 2.87 = 67.4 + 0.35 = 10 - 4.7 =
2.42 + 5.3 = 40 - 5.91 = 16.57 + 3.28 =
5.4 - 0.62 = 7.35 + 0.65 = 0.49 - 0.09 =
0.27 + 0.73 = 7.25 + 2.75 = 1.4 + 0.04 =
7.5 + 0.75 = 0.73 - 0.47 = 1 - 0.92 =
1.68 - 1.5 = 5.5 - 1.82 = 0.77 + 0.44 =
6.3 - 4.8 = 5.42 + 1.62 = 3.7 - 1.25 =
0.6 + 0.43 = 4 + 0.75 = 0.38 + 2.19 =

二、用竖式计算。
20.5 - 14.76 28.46 + 6.87 10 - 7.42

答案： 5.74 35.33 2.58

一、直接写出得数。
12.3 + 1.23 = 6.8 + 1.28 = 78 - 0.98 =
0.58 - 0.19 = 0.64 - 0.36 = 0.86 + 0.3 =
