642÷6=
288÷4=
84÷3÷4=

68÷2=34
95-68=27
108-23=85
87÷29÷3=1
32+28=60
48+39=87
954÷3=318
150-25÷5=145
1.2+1.5=2.7
388-236=152
5.9+0.82=6.72
360÷(12+28)=9
41×20=820
136×2=272
250×60=15000
156+44÷2=178
320-80=240
21×7=147
77×5=385
50×99×2=9900
3.8-0.8=3
0÷234=0
215÷5=43
7.35-0.35-4=3
650÷50=13
0.43-0.3=0.13
174÷2=87
5.8+2.1-0.38=7.52

288÷4=72
84÷3÷4=7

二、用竖式计算，带☆的要验算。（每题3分，验算各2分，共22分）
12.67 + 5.4 =
350 × 29 =
☆18 - 0.73 =
267 × 45 =
370 ÷ 52 =
☆792 ÷ 38 =

12.67 + 5.4 = 18.07
350 × 29 = 10150
☆18 - 0.73 = 17.27
267 × 45 = 12015
370 ÷ 52 = 7……6
☆792 ÷ 38 = 20……32
竖式及验算略

三、计算下面各题。（每题3分，共18分）
85 + 600 - 646 ÷ 34
53 × (45 + 69 - 32)
0.95 + 18.76 + 3.01
9.32 + 5.3 - 10.78
34 × (405 - 369) - 456
610 ÷ [(26 + 35) × 2]

85 + 600 - 646 ÷ 34 = 666
53 × (45 + 69 - 32) = 4346
0.95 + 18.76 + 3.01 = 22.72
9.32 + 5.3 - 10.78 = 3.84
34 × (405 - 369) - 456 = 768
610 ÷ [(26 + 35) × 2] = 5
