《2025年一本暑假计算加应用题四年级数学北师大版》

1. 直接写出得数。(每题 1★)
$3.2 + 0.6 = $3.8 $4.8 - 2.2 = $2.6 $1.33 + 4.6 = $5.93
$6.8 - 3.2 = $3.6 $0.77 - 0.51 = $0.26 $5.12 + 3.23 = $8.35
$4.2 + 5.39 = $9.59 $7.9 - 3.6 = $4.3 $5.2 + 1.62 = $6.82
$0.3 + 6.5 = $6.8 $6.34 - 5.11 = $1.23 $0.8 + 2.1 = $2.9
$0.59 + 3.3 = $3.89 $4.8 + 1.1 = $5.9 $6.49 - 1.23 = $5.26
$9.6 - 5 = $4.6 $9.9 - 7.7 = $2.2 $1.57 + 7.33 = $8.9

答案： 3.8 2.6 5.93
3.6 0.26 8.35
9.59 4.3 6.82
6.8 1.23 2.9
3.89 5.9 5.26
4.6 2.2 8.9

2. 用竖式计算。(每题 4★)
$14.59 - 3.28 = $11.31 $7.44 + 12.17 = $19.61 $17.1 - 5.23 = $11.87

$8.22 - 5.72 = $2.5 $33 - 11.59 = $21.41 $15.4 + 18.82 = $34.22

$16.07 + 4.95 = $21.02 $154.59 + 12.8 = $167.39 $23.02 - 13.94 = $9.08(竖式略)

答案： 11.31 19.61 11.87
2.5 21.41 34.22
21.02 167.39 9.08(竖式略)
