1、口算。0.7+0.9= 0.8+0.6= 8.24+3.76= 4.1-3.8= 14+0.78= 14.6-0.34= 1.3+8.56= 0.8-0.55= 4-0.04= 1-0.03= 30.5

+3.05= 0.8

-0.45= 0.78

+2.2= 5

-0.08=

3.25+0.75= 10-0.1= 1.5-0.5= 1-0.9= 2.3+0.6=

0.9+0.8= 1.9-0.9= 3.5- 2.4= 0.36+0.64= 0.96-0.3=

3.5+4.2= 6-0.5= 2.7-0.4= 1-0.3= 0.8+ 0.7= 4.5-3= 7.8-1.1= 3.4-1.5= 1.5

-0.5= 1-0.9=

2.3+0.6= 0.9+0.8= 1.9-0.9= 3.5 -2.4= 0.36+0.64=

0.96-0.3= 1.5-0.5= 1-0.9= 2.3+0.6= 0.9+0.8=

1.9-0.9= 2、计算下列各题8.65-6.31= 10

-7.64= 13.6

+8.46= 0.99

+1.1= 1.23+6.52=

5.32-0.93= 6.35-5.23= 1.23+5.69= 1.26+5.21= 0.96-0.23= 7.26-4.93= 2.16-0.23= 9.28+7.32= 5.2-0.9= 2.65+9.32= 4.63+8.92= 7.65-6.23= 8.28+4.75= 9.23+5.45= 6.23-4.53= 6.52+2.63=

4.62+8.95=

7.24+6.21= 8.52+4.65=

10-3.653.2+1.73= 18.7

+3.14= 23.5

-2.8=

3、脱式计算,能简便的要简便简便计算。(注意书写整洁)45.55-(6.82+15.55) 34.52

-17.87-12.23 3.6-1.28+3.09

4.32-(1.26+2.34) 2.5+3.25+0.75+7.5 4.57+3.17+3.43+5.83

23.75-8.64-3.36 17.83-9.5-7.83-0.5 3.45+8.7+16.55+1.3

8.54-5.96 27.38-5.34+2.62-4.66 21.63-(8.5+9.63)

3.6-1.28+3.09 4.321.26+2.34) 2.5+3.25+0.75+7. 5
