二、计算下面各题。
$18 - 3.58 + 2.56$ $20.3 + 9.95 - 3.49$ $8.67 + 14.5 - 15.7$
$7.3 - 2.38 + 23.6$ $10 - 1.29 + 3.67$ $1.34 + 3.87 + 5.2$

答案

16.98 26.76 7.47 28.52 12.38 10.41

解析

18 - 3.58 + 2.56 = 14.42 + 2.56 = 16.98
20.3 + 9.95 - 3.49 = 30.25 - 3.49 = 26.76
8.67 + 14.5 - 15.7 = 23.17 - 15.7 = 7.47
7.3 - 2.38 + 23.6 = 4.92 + 23.6 = 28.52
10 - 1.29 + 3.67 = 8.71 + 3.67 = 12.38
1.34 + 3.87 + 5.2 = 5.21 + 5.2 = 10.41
