一、直接写出得数。
$7.2 + 0.82 =$ $10 - 9.12 =$ $2.03 + 3.7 =$
$0.01 + 10.99 =$ $1.1 - 0.01 =$ $1 - 0.02 =$
$14.8 + 2.2 =$ $1.4 + 0.46 =$ $5.9 - 2.35 =$
$0.8 - 0.35 =$ $2.5 + 1.37 =$ $12 - 1.2 =$
$5.33 + 0.67 =$ $4 - 3.6 =$ $1.82 - 0.63 =$
$7.8 - 0.22 =$ $0.9 + 2.11 =$ $9.8 - 0.98 =$
$0.38 + 0.64 =$ $2 - 1.08 =$ $2.2 + 9.1 =$
$3.05 - 1.35 =$ $10 - 4.35 =$ $12.6 + 7.08 =$
$63.02 + 13.68 =$ $7.82 - 7.2 =$ $2.19 + 9.11 =$
$1.9 + 7.5 =$ $7.64 - 2.47 =$ $9.65 - 5.13 =$

答案： 8.02 0.88 5.73
11 1.09 0.98
17 1.86 3.55
0.45 3.87 10.8
6 0.4 1.19
7.58 3.01 8.82
1.02 0.92 11.3
1.7 5.65 19.68
76.7 0.62 11.3
9.4 5.17 4.52

二、用竖式计算。
$5.82 + 2.58$ $100 - 1.87$ $4.57 + 28.9$

答案： 8.4 98.13 33.47

一、直接写出得数。
13.84 - 5.8 = 3.86 + 7.23 = 7.8 - 0.08 =
4.57 - 4.07 = 4.05 + 4.5 = 2.09 + 3.44 =
2.75 - 1.8 = 0.99 + 1.8 = 7.2 - 0.95 =
0.48 + 0.52 = 3.38 + 4.07 = 4.3 - 0.22 =
9.4 - 0.04 = 1.04 - 0.8 = 1.37 + 3.7 =
7.2 + 2.8 = 0.49 + 0.51 = 42.8 - 4.28 =
6.2 - 0.6 = 21.5 + 9.5 = 32 - 0.86 =
2.63 + 0.37 = 1.5 - 0.45 = 8 + 2.5 =
3.66 + 2.24 = 5.9 - 3.6 = 16.82 - 4.9 =
7.32 + 2.68 = 4.32 + 5.34 = 2.65 - 0.53 =
