一、直接写出得数。
0.36 + 5.42 = 1.98 - 0.04 = 0.32 + 0.5 =
10.8 - 5.4 = 5.63 - 2.3 = 8.79 - 0.48 =
0.75 + 1.2 = 0.41 + 0.56 = 4.7 + 2.04 =
1.15 - 0.03 = 1.23 + 6.35 = 1.75 - 0.6 =
0.51 + 1.3 = 3.2 + 1.68 = 32.8 + 1.1 =
4.09 + 3.7 = 1.02 + 0.97 = 7.3 - 1.2 =
16.8 - 8.6 = 1.47 - 0.32 = 0.46 + 6.4 =
10.4 + 5.3 = 3.5 + 0.16 = 4.73 + 2.25 =
2.2 + 6.3 = 3.8 - 1.7 = 8.95 - 7.24 =
1.85 - 0.12 = 5.16 + 0.31 = 4.6 - 3.2 =
